Cospas-Sarsat system A satellite system designed to detect distress beacons transmitting on the frequencies of 121.5 MHz and frequency of 406 MHz
- Add new entries:
Locating The finding of ships, aircraft, units or persons in distress
Place of safety A location where rescue operations are considered to terminate; where the survivors' safety of life is no longer threatened and where their basic human needs (such as food, shelter and medical needs) can be met; and, a place from which transportation arrangements can be made for the survivors' next or final destination. A place of safety may be on land, or it may be aboard a rescue unit or other suitable vessel or facility at sea that can serve as a place of safety until the survivors are disembarked to their next destination.
3 Chapter 2
- Add new paragraph 2.1.3:
2.1.3 Establishment of the global aeronautical and maritime SAR systems under their respective international conventions provides the framework for a national system to handle SAR matters on land within the State and its SRR. Local government authorities and police would typically have the responsibility for land SAR and may not involve an RCC. However, the national SAR system should have arrangements in place for coordination with local authorities for land
MSC.1/Circ.1415 Annex, page 2
I:\CIRC\MSC\01\1415.doc
SAR response, as appropriate. In some cases, the national SAR system may be designated as being responsible for conducting certain land SAR operations; or, it may have a supporting role because the RCC received the initial alert or the local authorities requested the support of nearby national SAR facilities.
4 Chapter 4
- Replace paragraphs 4.2.2 (e), 4.2.3 and 4.2.4 with the following text:
4.2.2 (e) Common Language. The need for RCC staff and SAR unit crews to be proficient in speaking, writing and comprehending a common language to ensure effective information transfer is vital to successful conduct of SAR operations. In the case of a SAR action involving cooperative input from a number of RCCs and SRUs within a region, the most convenient language may be a common regional language. In the case of a SAR action likely to extend beyond regional areas, the appropriate common language is English. English, in any case, serves as the default SAR operational language in all cross-boundary operations where there is no other common language. Defining and mandating specific levels of proficiency in languages for RCC staff and SRU crews is, however, impractical because the regulatory framework of SAR services is insufficiently robust to support its implementation and maintenance. SAR service providers should, nonetheless, appreciate that where there is dependence upon spoken communication, mistaken transfer of operational information has been shown to be the most common causal factor in the occurrence of accidents and incidents and that every effort should be made to mitigate its risks by requiring SAR staff to attain a high level of appropriate language proficiency. As supportive tools, in undertaking coordination across language barriers, SAR service providers may take advantage of commercial interpretation services that are now readily available. Confirmation of verbal conversations with facsimile or other written messages can reduce misunderstandings and expedite coordination processes.
4.2.3 Publications which can be used to alleviate language barriers between vessels, aircraft, survivors, and SAR personnel include: the International Code of Signals, the Standard Marine Communication Phrases (SMCP) and Appendix I – SITREPs and Codes, of IAMSAR Manual, volume II. These documents should be included in RCC libraries and be understood by the staff who should be able to recognize coded messages based on these references. Ships should carry these documents and SRUs should carry the Code.
4.2.4 While tools like the International Code of Signals and SMCP are readily available and can be genuinely useful, they should not be thought of as total solutions for the challenges of communicating effectively across language barriers. Because of the range of topics and behaviours requiring common understanding, effective transfer of information in situations of operational emergency is dependent upon a very comprehensive command of language. Thus, no form of standardized phraseology or code can address the extent of need. A high level of proficiency in common (or plain) language is necessary.

I:\CIRC\MSC\01\1415.doc
- Add new paragraph after paragraph 4.5.17:
4.5.18 406 MHz distress beacons can be registered in the International 406 MHz Beacon Registration Database (IBRD), available online and free-of-charge. The IBRD provides access to beacon owners who wish to directly register their beacons in the IBRD, when no registration facility exists in their country or the responsible Administration has agreed to allow direct registration in the IBRD. Administrations can also opt to centrally control the registration of beacons identified with their country code, but wish to make registration data available to international SAR services via the IBRD.
All SAR services need to access beacon registration data held in the IBRD to efficiently process distress alerts. Administrations should designate a National Point of Contact to the Cospas-Sarsat Secretariat (contact details are contained in Appendix D). Cospas-Sarsat will accept designations from the Cospas-Sarsat Representative or, for non- participating countries, the representative of an IMO or ICAO Member State. Cospas-Sarsat will provide each National IBRD Point of Contact with user identifications and passwords to be used by:
- National Data Providers for registration of beacons with their country code(s);
- SAR services for IBRD queries; and
- authorized shore based service facilities and inspectors to verify proper coding and actual registration of the beacon.
These IBRD user identifications and passwords should be distributed within each country under the responsibility of the National IBRD Point of Contact.
Further guidance on the IBRD registration process, including a letter template to request password access to the IBRD for SAR services, is provided on the Cospas-Sarsat website.

- Introduction of GMDSS aboard only some vessels adds capabilities for those vessels, but also introduces incompatibility between those vessels and vessels not GMDSS-equipped. It also introduces need for SAR authorities to support two maritime mobile systems both ashore and afloat. IMO recognizes this incompatibility and has developed guidance on some matters common to SOLAS-convention vessels and non-regulated craft; and, decided that all GMDSS ships, while at sea, shall continue to maintain, when practicable, a continuous listening watch on VHF channel 16 since When most ships discontinue watchkeeping on Channel 16, most small vessels will still depend on channel 16 for distress, safety and calling.
- Rename section G.6, as follows:
- G.6 406 MHz Distress Beacons
- Replace paragraphs G.6.1, G.6.2 and G.6.3 with the following paragraphs:
G.6.1 There are three types of 406 MHz distress beacons: the maritime emergency position-indicating radio beacon (EPIRB) which is part of the GMDSS, the aeronautical emergency locator transmitter (ELT), and the personal locator beacon (PLB). All three types of this distress beacon have their signals relayed via Cospas-Sarsat satellites, local user terminals (LUTs) and mission control centres (MCCs) to SAR Points of Contact (SPOCs) which include RCCs.
G.6.2 Many civil aircraft worldwide, especially operating on international flights and over ocean areas, are required to carry the 406 MHz distress beacon. However, some national regulations may allow for the 121.5 MHz ELT on domestic flights. This old style ELT depends on other aircraft or airport facilities to detect its aural signal.
- Amend paragraph G.6.4, as follows:
- Most ELTs and EPIRBs 406 MHz Distress Beacons provide a homing signals capability on 121.5/243/406 MHz; some also on 243 MHz, and some may also integrate SARTs into their designs.
MSC.1/Circ.1415 Annex, page 8
I:\CIRC\MSC\01\1415.doc
- Renumber paragraphs G.6.4 and G.6.5 to G.6.3 and G.6.4.
- Add new paragraph after paragraph G.6.4:
G.6.5 The 406 MHz PLB is not a mandated international carriage requirement, but may be carried on a person and has similar characteristics to EPIRBs and ELTs. However, the PLB has different specifications.
- Add on Page G-4, new section, as follows:
G.9 Mobile Telephone – Satellite and Cellular
G.9.1 A mobile telephone can be a satellite or cellular telephone. The satellite telephone connects to orbiting satellites and can provide regional or global coverage. Cellular telephones connect to a local terrestrial network of radiocommunications base stations known as cell sites. The mobile telephone enables the caller to connect to and from the public telephone network including other mobile telephones, and fixed telephone lines. Portable satellite and cellular telephone systems were not developed as part of the international SAR system and have limitations for distress alerting. But, since any available means may be used for distress alerting, national administrations should make appropriate arrangements and establish procedures to handle distress alerts from mobile telephones.
G.9.2 Due to the widespread use of cellular telephones, specific guidance has been provided in the IAMSAR Manual, volume II, chapter 2 Communications. Many aspects of the guidance in that section regarding cellular telephones can also apply to the satellite telephone.

"Inmarsat sometimes finds it necessary to bar a vessel's SES from transmitting and receiving communications. In such cases, the SES can still be used by vessels to send distress alerts or make distress calls. In the case of an emergency an RCC will initially attempt to contact the vessel, to ascertain whether the distress alert is real or inadvertent. If the RCC is unable to communicate with the vessel, they will then check its status in the "MRCC Database". Mandatory or discretionary barring will prevent communications with the vessel. The RCC may then call its associated
MSC.1/Circ.1415 Annex, page 25
I:\CIRC\MSC\01\1415.doc
LES, to confirm the barring status of the terminal. The LES will verify the status by referring to the appropriate tables (barring/authorization, etc.). If the terminal status is confirmed as barred, the RCC will then request the LES to unbar the terminal so that communications with the vessel can be established.

"Any RCC that is not associated with an Inmarsat LES may not know through which LES it is attempting to communicate with a vessel. There can be a number of reasons why a non-associated RCC is unable to communicate with the vessel, including barring of the vessel or local/national telecommunication issues. If local/national telecommunication issues are not relevant and barring is suspected, the RCC should first try to contact the vessel via an Inmarsat-associated RCC, who will be able to arrange for the barring to be lifted. Alternatively, the non-associated RCC may contact either Inmarsat Customer Services or Inmarsat NOC (or both) which operate on a 24-hour basis. Inmarsat will check its Electronic Service Activation System (ESAS) for the correct status of the terminal, i.e. active, barred, etc. If the terminal is found to be active and not barred, Inmarsat will assist the RCC by providing any other information or advice as requested."

"Vessel Tracking Communications
Various forms of communication can be used for vessel tracking. Ship reporting systems can use voice reporting over VHF and HF, DSC and Inmarsat. Many ship reporting systems use Inmarsat-C polling or Inmarsat automated position reporting (APR). AIS uses a time-division multiple access (TDMA) scheme to share the VHF frequency, also known as the VHF Data Link (VDL). There are two dedicated frequencies used for AIS – AIS 1 (161.975 MHz) and AIS 2 (162.025 MHz). LRIT can employ any form of communication which meets the required functional specification, but most vessels use Inmarsat equipment to report every six hours to their data centre via a communications service provider and application service provider. A vessel monitoring system (VMS) can use various systems for tracking, including Inmarsat, Iridium and Argos."

Insert new subparagraph (b) and include the following text (and renumber all subparagraphs of paragraph 3.8.6 accordingly):
"The term "cold" can be applied to water as warm as 25°C (77°F): long periods of immersion in water as high as this temperature can result in a fall in deep body temperature. It follows that most of the planet is covered in "cold" water". Delete text "to avoid frostbite. In temperature below 18º Celsius (0º F, survivors become easily fatigued." in subparagraph (c) (old subparagraph (b)).
Replace text of subparagraph (d) (old subparagraph (c)) with the following text:
"The warmest ocean water that can be expected at any time of year is 29°C (84°F). About one third of the earth's ocean surface has water temperatures above 19°C (66°F). Figure N-14 in appendix N shows the realistic upper limit of survival time for people wearing normal clothing in water at various temperatures. The graph is based on the analysis of known survival cases and laboratory experimentation, and shows a reasonable upper limit for search duration. But the search planner must remember that this graph can only be indicative and that a number of uncertainty factors can improve or reduce survival time."
Insert new subparagraph (e) and include the following text:
"Guidelines based on analysis of accidents, together with laboratory-based experimental evidence, show a clear correlation between water temperature, body cooling and survival times. However, it is also apparent that, because of the vast array of personal factors that can influence survival time in cold water, this time can vary from seconds to days. Factors that slow the loss of body heat are:
 high body fat;  heavy clothing;  survival clothing; and  the use of a protective behaviour.
Factors that make a person lose body heat faster are:
 gender (females are more prone to hypothermia);  age (children and the elderly are more prone to hypothermia);  low body fat;  light clothing;  exercising (such as situations where persons without lifejackets have to swim); and  seasickness.
MSC.1/Circ.1415 Annex, page 28
I:\CIRC\MSC\01\1415.doc
Thus, in water at 5°C (41°F), the 50 per cent survival time for a normally clothed individual is estimated to be about one hour, with a recommended search time of six hours. The corresponding times for 10°C (50°F) are two hours and 12 hours. While in water at 15°C (59°F) the 50 per cent survival time is about six hours, with the recommended search time of 18 hours. Between 20°C (68°F) and 30°C (86°F) search times exceeding 24 hours should be considered, and searching for several days should be considered for water temperatures at the upper end of this temperature scale.
As there are many factors to consider, this model cannot be used for all situations. SOLAS survival suits are meant to keep a person alive for 24 hours in extremely cold water; and, a person may be able to keep himself out of the water by climbing onto wreckage, for example. It should be kept in mind that factors working positively on survival times are often unknown to the SMC. Some of these factors include, but are not limited to the following:
 Near-naked swimmers would be at the lower ranges of these times. In calm water there may be an exceptional individual (someone who is very fat and fit) who will exceed expectations. If it is known that the victim is such an individual, consideration should, exceptionally, be given to extending the search times from 3-6 to 10 times the predicted 50 per cent survival time.
 For inshore incidents, survival times may be less because of breaking water and adverse currents. However, consideration must be given to the possibility that the inshore survivor managed to get ashore. Consequently, the limiting effects of cold water cooling will no longer be the only consideration, and the search must be continued until the shore has been thoroughly searched.
 For offshore incidents, it is reasonable to expect that individuals may be better equipped to survive and have access to appropriate protective clothing, lifejackets and possibly liferafts. Consequently, search times for them should be at the upper limits of those expected (10 times predicted 50 per cent survival time), unless obviously adverse conditions prevail – and should exceed them if it is possible that survivors may have been able to get out of the water.
 Survival time is shortened by physical activity (such as swimming) and increased by wearing heavy clothing and, if wearing a lifejacket, adopting protective behaviour (such as huddling with other survivors or adopting a foetal position in the water). Specialized insulated protective clothing (such as immersion suits or wet suits) is capable of increasing survival time from 2 to 10 times. The SMC should bear in mind that ingress of as little as half a litre of water into an immersion/survival suit can reduce its insulation value by 30 per cent, and that wave height of one metre can reduce it by an additional 15 per cent.
Predicting survival times for immersion victims is not a precise science; there is no formula to determine exactly how long someone will survive, or how long a search should continue. The SMC must make some difficult decisions based on the best information available and a number of assumptions, and should extend the search time beyond that which they can reasonably expect anyone to survive."

"Scenario analysis and development, along with related investigative efforts to obtain more information, often determine a successful outcome to the distress incident. The search planner must think like a detective who is trying to solve an important case or a scientist who is trying to answer an important question. Lines of evidence must be followed to see where they lead. The available facts must be viewed from different perspectives. Missing information must be filled in with different, but plausible, assumptions to create plausible scenarios. At times, several scenarios can be developed that are consistent with all or most of the known facts. These scenarios must be carefully evaluated and weighted according to the search planner's judgement about which scenarios are more likely and which are less likely to represent the actual situation. These efforts can be difficult, demanding tasks and require dedication by the search planner to attain the best chance for success."

Replace text of paragraph with the following text:
"The same basic theory of search applies on land as well as in the marine environment. In both cases, the goal is to increase the cumulative POS as quickly as the available resources will allow. However, the planning methods and search techniques used on land are often different from those used in the marine environment. If the initial search object is a forced landing site, then search object motion is likely not an issue. If the search object is a lost or missing person, whether from a forced landing site or some other circumstance such as a lost hiker, hunter or child, search object motion may be an issue. However, in these cases, the influences of lost person's behaviour, weather, terrain, and vegetation take the place of winds, currents, and drift. Aerial search effectiveness is reduced over areas that are mountainous or covered with significant amounts of vegetation. Searching with land facilities may be the only alternative. Land facility search procedures are covered in the International Aeronautical and Maritime SAR Manual for Mobile Facilities."
MSC.1/Circ.1415 Annex, page 33
I:\CIRC\MSC\01\1415.doc
- Add new paragraph 5.18.2 and insert the following text:
"Searching for lost persons with ground parties may involve large numbers of searchers. Logistics (keeping track of searchers and providing food and shelter for them) can become quite complex, especially in remote areas. Search environments, and hence sweep width values, can vary dramatically over short distances, such as when pasture lands and dense forests are adjacent to one another. Search assignments normally involve small teams of persons. Search areas are based on terrain, vegetation, a corresponding estimated search speed, sweep width, etc. Decisions about which areas to search when there are insufficient search facilities should be determined by where the cumulative POS can be increased at the greatest rate. Search area boundaries are normally defined by physical features such as ridgelines, water boundaries, roads, trails, fences, visible power lines and pipelines, etc. These search areas may have irregular shapes. Decisions about the best balance between team size (number of persons) and assigned area size must be made. Additional "search" techniques include searching for signs of the lost person's passage (footprints, discarded items, disturbed vegetation, etc.), the use of trackers, both human and animal, and establishing a perimeter around the overall search area, then patrolling it for signs that the lost person crossed the perimeter and left the original search area."
- Insert new paragraph 5.18.3 and include the following text:
"Search effectiveness can be improved by combining air assets with ground parties."
- Insert new section 5.21 called "Geographic Referencing" and include the following text in new paragraph 5.21.1:
"If position information is communicated in Latitude and Longitude format in the planning and conduct of a SAR operation, it is recommended that the Degrees, Minutes, Decimal Minutes (DD° MM.mm') format be used."
- Insert new paragraph 5.21.2 and include the following text:
"Geographic referencing refers to the ability to locate a point on the Earth's surface, either physically or on a chart or map. A system of coordinates is used to define a location in physical space. Mariners and aviators typically use latitude and longitude to define their position but these coordinates can be displayed in different ways and people on land may use a different coordinate system, such as a grid system. On land after a major disaster or in undeveloped areas, landmarks and navigational aids, such as roads, may not be recognizable so the use of a coordinate system may be the only way to find specific locations. Search facilities must have a good geographic reference system to conduct an effective search as well as to safely operate near each other, especially to avoid airspace traffic conflicts."
MSC.1/Circ.1415 Annex, page 34
I:\CIRC\MSC\01\1415.doc
- Insert new paragraph 5.21.3 and include the following text:
"Charts and maps have two primary difficulties in providing a location: (1) showing the Earth's spherical shape as a flat surface, and (2) the Earth is not a perfect sphere. Another complication is States using a different basis, or datum, for developing charts. Also, land maps may use a local reference point to show positions on the basis of grid distances (usually east and north, in metres) from the reference point. These concerns usually do not interfere with routine, local SAR operations but they can become significant concerns when assisting other States or coordinating with local authorities during disasters. Search planners and SAR facilities need to be aware of these differences, and when feasible, should be using the same charts and maps as well. If it is not possible for all personnel and facilities to use the same coordinate system and maps or charts, the SMC should be prepared to convert position data from one system to another and ensure positions are provided in the appropriate form for use. SAR facilities and personnel using electronic navigation systems (e.g. GNSS) must ensure their navigation devices are set to the appropriate datum and coordinate system."
- Insert new paragraph 5.21.4 and include the following text:
"For routine SAR operations, Mass Rescue Operations or large scale disasters, SAR agencies must be able to understand how geographic information is communicated among the SMC, OSC, ACO and various SAR facilities. This becomes an even greater challenge when SAR facilities transition between maritime and land-based SAR operations, or in large-scale disaster operations that involve many different SAR facilities that may have different ways to communicate position information. In the development of State and regional SAR plans, States should consider concerns such as:
How does the SMC effectively use position information from external sources (e.g. general public, other agencies (non-emergency and emergency), etc.) and communicate that position information accurately and efficiently to various aeronautical, marine or land-based SAR facilities in forms they can use?
Do States have unique, national coordinate systems that may not be familiar to other international SAR facilities requested to assist in a SAR, MRO or disaster response operation?
What is the "right" reference system that should be used for a specific SAR, MRO or disaster response operation?
Is there only one reference system that satisfies the requirements of all SAR facilities? If there is more than one reference system, how is the data translated and sent to the various SAR facilities?
How and when is position information in one reference system converted to another?
How is position information received in non-standard formats (street addresses, landmark names, etc.) converted to a standard reference format?
In large scale MRO and disaster operations, how do SAR facilities navigate when landmarks such as street signs and homes are destroyed?
MSC.1/Circ.1415 Annex, page 35
I:\CIRC\MSC\01\1415.doc
How do multiple SAR facilities safely and efficiently operate in the same area, particularly for mass rescue operations? For aeronautical SAR facilities, avoiding airspace traffic conflicts is a major safety issue to prevent mid-air collisions. The safe operation of multiple aviation SAR facilities in the same area may be highly dependent on all units having a common and accurate sense of their location in relation to other aviation units."
- Insert new paragraph 5.21.5 and include the following text:
"Latitude and longitude are angular measurements in degrees (the symbol, " ° "), minutes (the apostrophe symbol, " ′ "), and seconds (the quotation symbol, " ″ "). However, Latitude and Longitude can be read and written in different formats such as:
 Degrees, Minutes, Decimal Minutes (DD° MM.mm′);  Degrees, Minutes, Seconds (DDº MM′ SS″); and  Degrees, Decimal Degrees (DD.DDDDº)."
The SC should standardize how position information is communicated by the SMC, OSC, ACO and SAR facilities to limit confusion in assignments (search areas, survivor locations, etc.) and SAR planning."
9 Chapter 6
- Amend the following text in paragraph 6.8.1:
Delete last sentence in paragraph 6.8.1.
Add text "Survivors might need to be advised to focus on keeping themselves alive rather than trying to assist in their rescue since this could improve their chances of survival." at the end of paragraph.
- Insert new paragraph 6.8.2 and include the following text (and renumber all paragraphs of section 6.8 accordingly):
"When hoisting a person who may be suffering from hypothermia, especially after long-term immersion in water, and especially when lifting them some distance, such as to the deck of a high-sided vessel or into a helicopter, they should be lifted horizontally or near-horizontally. Hoisting such persons in a vertical position may cause loss of consciousness, severe shock or cardiac arrest. A rescue lifting system, rescue basket or stretcher should be used, or two strops or loops with one under the arms and the other under the knees."
- Amend the following text in paragraph 6.13.20:
Delete subparagraph (c).
- Amend the following text in paragraph 6.15.5:
Add text "(MRO communications are discussed in more detail later in this chapter)" at the end of third bullet.
- Insert new section "Communications planning for MROs" after paragraph 6.15.35 (add two new paragraphs and renumber all paragraphs following the new 6.15.37).
MSC.1/Circ.1415 Annex, page 36
I:\CIRC\MSC\01\1415.doc
- Insert new paragraph 6.15.36 and include the following text:
"Efficient MRO responses depend upon efficient communication – and efficient communication requires planning, understanding of the plan by those who will have to put it into effect and its rapid implementation at the time of the incident. The following are some of the factors MRO communications planners are recommended to consider:
 Who is likely to be involved in the response to a MRO, including supporting organizations and others with legitimate interest (for example, officials, family members of victims, and the news media)?  What are their information needs likely to be?  Where do they fit in the overall command, control and coordination (and therefore communications) structure?  What are the information priorities?  What communications facilities do the responders have?  Are there enough people to operate the communications systems, potentially over a long period? The planning should include provision for relief personnel.  How should these facilities best be used to avoid overload? How should large amount of data (such as search plans or passenger lists) be communicated?  Do people know what to say and who to talk to? Do they understand their unit's place in the communications network, other units' roles, and the overall information priorities? Are they aware of the importance of clear procedures and communications discipline?  Are there likely to be language difficulties, including potential misunderstanding of technical language?  Who will "control and keep order" on the various parts of the communications network, and do they understand this particularly important role?  To what extent are different responders' communications systems and procedures interoperable? Can communications hubs be established or liaison officers exchanged, to help explain priorities, procedures and technical language?  How long might the incident last? Distress frequencies may be used for their initial response, but the plan should ensure that these frequencies are cleared as soon as practicable."
- Insert new paragraph 6.15.37 and include the following text:
"Appendix C outlines a basic MRO communications plan structure."
10 Chapter 7
- Amend the following text in paragraph 7.3.1:
Add text "VHF" between "and" and "HF" in second sentence.
- Replace the text of paragraph 7.4.2 with the following text:
"In situations such as piracy or armed robbery against ships where the ship or crew is in grave and imminent danger, the master may authorize the broadcasting of a distress message, preceded by the appropriate distress alerts (MAYDAY, DSC, etc.), using all available radiocommunications systems. Also, ships subject to the SOLAS Convention are required to carry equipment called the Ship Security Alert System (SSAS) for sending covert alerts to shore for vessel security incidents
MSC.1/Circ.1415 Annex, page 37
I:\CIRC\MSC\01\1415.doc
involving acts of violence against ships (that is, piracy, armed robbery against ships or any other security incident directed against a ship). The system is intended to allow a covert activation to be made which alerts the competent authority ashore and denies knowledge of its activation to perpetrators of the acts of violence. Under the SSAS concept, national governments should establish a security forces authority to be in charge of providing the response to such security incidents. The RCC, due to it being available on a 24-hour basis, is often the first point of contact between the ship and coastal authorities concerned. Two common systems for transmitting SSAS alerts are Inmarsat and Cospas-Sarsat. (A sample SSAS alert message is found in appendix B, under RCC-Cospas-Sarsat Message Formats.) National procedures can vary but the role of the RCC, if involved, is usually to receive the SSAS alert and inform the security forces authority that will be in charge of the response. Actions taken by the RCC upon receiving a covert SSAS alert include:
 do not acknowledge receipt of the alert;
 do not attempt to contact the ship originating the alert;
 do not send any communications to other ships in the vicinity of the ship under threat unless directed by the security forces authority;
 if the position of the incident is within its SRR, the RCC should immediately inform its national security forces authority;
 if the position of the incident is outside of its SRR, the RCC should relay the alert to the appropriate RCC using the normal methods of communications; and
 place SAR resources on standby, if appropriate, since it may become a SAR case."
- Amend the following text in paragraph 7.6.1:
Add text ", or vessels, craft or life-saving appliances left adrift at sea that may cause an unnecessary SAR alert in the future." at the end of fourth sentence.
Add text "or recovery" between "repairs" and "by" and delete text "more complicated" in fifth sentence.
- Amend the following text in paragraph 7.7.1:
Add text "As recommended in annex 14, the plan should provide for cooperation and coordination with the rescue coordination centre, as necessary." after first sentence.
Add text "The plan is to include the ready availability of, and coordination with, appropriate specialist rescue services to be able to respond to emergencies where an aerodrome is located close to water and/or swampy areas or difficult terrain and where a significant portion of approach or departure operations takes place over these areas." at the end of the paragraph.
MSC.1/Circ.1415 Annex, page 38
I:\CIRC\MSC\01\1415.doc
- Replace text of paragraph 7.7.2 with the following text:
"Aerodromes should make provisions with local SAR service providers for water rescue and mass casualties near aerodromes as appropriate. The aerodrome emergency plan is required to contain procedures for periodic testing of the adequacy of the plan and for reviewing the results in order to improve its effectiveness. Testing may be by joint exercises conducted so that:"
11 Chapter 8
- Amend the following text in paragraph 8.1.1:
Replace text of last bullet with the following text:
"during the distress phase, the SMC or other proper authority determines that further search would be to no avail because additional effort cannot appreciably increase the probability of successfully finding any remaining survivors or because there is no longer any reasonable probability that the distressed persons have survived."
- Amend the following text in paragraph 8.2:
Add text "and rescue personnel and facilities are returning to normal duties" at the end of first sentence.

- Add section C-5 on MRO communications in a maritime incident.
- Amend the following text in the MRO exercises section:
Add text "and operations" at the end of the last bullet of section.
- Amend the following text in the MRO incident management section:
Replace text "and" with "a" after text "and demands of" in sub-bullet Incident Command System.
- Insert section C-5 MRO Communications in a maritime incident and add the following text:
"MRO communications in a maritime incident
Efficient communications in major maritime response incidents are best arranged by dividing communications between several different frequencies. The number of frequencies used may vary, depending on the circumstances, but is unlikely to exceed five. The diagram below shows a major incident with numerous surface and air units responding and several different activities taking place on scene and, in support, ashore. But the communications plan set up to deal with this incident is relatively simple so that all those responding may readily understand it. And, it needs to be established from the outset which could include relations to the media (see also chapter [volume III, section 2]).
MSC.1/Circ.1415 Annex, page 45
I:\CIRC\MSC\01\1415.doc
Concept of a communications plan for a major incident
1 The primary coordinating frequency – initially VHF FM Channel 16 but a common working frequency may be assigned to ensure Channel 16 is available for other distress alerts – is used by the casualty, the OSC, the ACO (if designated) and, if possible, the SMC. If the incident is out of the SMC's VHF range, the SMC will communicate primarily with the OSC by satellite or MF or HF radio communications. Other units on scene should monitor the primary coordinating frequency if possible, to be kept up to date by SITREPs, etc., but will not usually transmit on it.
2 Surface SAR units and other surface units such as ships responding to the distress alert will use a second frequency – usually VHF FM channel 6 – controlled by the OSC.
OSC
Specific operations: searches, etc.
Winching operations
Shoreside authorities for example; the operators of a ship or aircraft casualty, harbour authorities, medical & fire fighting services, salvage & counter- pollution services, etc.

3 Aircraft may also use this second frequency under the OSC's control, if suitably equipped. If responding aircraft are not equipped with marine VHF or in cases where it would be more efficient to control them separately (such as multiple aircraft on scene) an ACO should be designated. The aircraft will then use a third frequency – usually VHF AM 123.1MHz – controlled by the ACO.
4 If other activities are taking place on scene, additional frequencies may be used for the necessary communications. If a helicopter, for example, needs to winch to or from a ship, these two units should switch to a mutually compatible frequency not already in use, returning to the main working frequencies after the winching operation is complete. Another example would be a search being conducted as part of the overall SAR operation. In this case the units assigned to the search will switch to a mutually compatible frequency controlled by a search coordinator. This coordinating unit reports to OSC or RCC as appropriate.
5 In a major incident, such as an MRO, there will need to be significant exchange of information with authorities ashore – the operators of a ship or aircraft casualty, harbour and other receiving authorities, shoreside emergency services providing support, authorities and agencies concerned with counter-pollution and salvage operations, and so on. These many organizations should communicate via the RCC, not directly with units on scene. This enables the SMC to maintain a clear overall picture of the response. Efficient procedures for this aspect of the communications plan can and should be pre-planned. The exchange of liaison officers is recommended."

PROPOSED AMENDMENTS TO IAMSAR MANUAL – VOLUME III
1 Foreword
- Replace the original text with the following text:
"The primary purpose of this volume, the "Mobile Facilities (volume III)" is to assist vessels and aircraft in the performance of a search, rescue, or on-scene coordinator function and with aspects of SAR that pertain to their own emergencies. It is intended to be carried aboard rescue units, aircraft and vessels.
A new edition is published every three years. The 2013 edition includes the 2010 amendments (adopted by ICAO and approved by IMO's Maritime Safety Committee at its eighty-seventh session in May 2010 that became applicable on 1 June 2011) and the 2011 and 2012 amendments (adopted by ICAO and approved by IMO's Maritime Safety Committee at its ninetieth session in May 2012 that became applicable on 1 June 2013). The amendments were prepared by the ICAO/IMO Joint Working Group on Harmonization of Aeronautical and Maritime Search and Rescue at its sixteenth session, in September 2009, seventeenth session, in September 2010, and eighteenth session, in October 2011, respectively, and were endorsed by the IMO Sub-Committee on Radiocommunications and Search and Rescue (COMSAR) at its fourteenth session, in March 2010, fifteenth session, in March 2011, and sixteenth session, in March 2012, respectively.
The Manual is published jointly by the International Civil Aviation Organization and the International Maritime Organization.
The IAMSAR Manual is subject to copyright protection under ICAO and IMO. However, limited reproducing of forms, checklists, tables, graphs and similar content is allowed for operational or training use.
Each IAMSAR Manual volume is written with specific SAR system duties in mind, and can be used as a stand-alone document, or, in conjunction with the other two volumes, as a means to attain a full view of the SAR system. Depending on the duties assigned, it may be necessary to hold only one, or two or all three volumes.
 The Organization and Management volume (volume I) discusses the global SAR system concept, establishment and improvement of national and regional SAR systems, and cooperation with neighbouring States to provide effective and economical SAR services;
 The Mission Coordination volume (volume II) assists personnel who plan and coordinate SAR operations and exercises;
The primary purpose of the three volumes of the International Aeronautical and Maritime Search and Rescue Manual is to assist States in meeting their own search and rescue (SAR) needs and the obligations they accepted under the Convention on International Civil Aviation, the International Convention on Maritime Search and Rescue, and the International Convention for the Safety of Life at Sea (SOLAS). These volumes provide guidelines for a common aviation and maritime approach to organizing and providing SAR services. States are encouraged to develop and improve their SAR services, to cooperate with neighbouring States and to consider their SAR services to be part of a global SAR system."

 When two or more SAR facilities are working together on the same mission, one person on-scene may be needed to coordinate the activities of all participating facilities.
MSC.1/Circ.1415 Annex, page 53
I:\CIRC\MSC\01\1415.doc
 The SMC designates an OSC, who may be the person in charge of a:
- search and rescue unit (SRU), ship, or aircraft participating in a search, or
- nearby facility in a position to handle OSC duties.
 The person in charge of the first facility to arrive at the scene will normally assume the OSC function until the SMC arranges for that person to be relieved.
 SAR Mission Coordinator
 Each SAR operation is carried out under the guidance of an SMC. This function exists only for the duration of a specific SAR incident and is normally performed by the RCC chief or a designee. The SMC may have assisting staff.
 The SMC guides a SAR operation until a rescue has been achieved or it becomes apparent that further efforts would be of no avail.
 The SMC should be well trained in all SAR processes, be thoroughly familiar with the applicable SAR plans, and:
□ gather information about distress situations □ develop accurate and workable SAR action plans □ dispatch and coordinate the resources to carry out SAR missions.
 SMC duties include:
□ obtain and evaluate all data on the emergency □ ascertain the type of emergency equipment carried by the missing or distressed craft □ remain informed of prevailing environmental conditions □ if necessary, ascertain movements and locations of vessels and alert shipping in likely search areas for rescue, lookout and/or radio watch □ plot the areas to search and decide on methods and facilities to be used □ develop the search action plan and rescue action plan as appropriate □ coordinate the operation with adjacent RCCs when appropriate □ arrange briefing and debriefing of SAR personnel □ evaluate all reports and modify search action plan as necessary □ arrange for refuelling of aircraft and, for prolonged search, make arrangements for the accommodation of SAR personnel □ arrange for delivery of supplies to sustain survivors □ maintain in chronological order an accurate and up-to-date record □ issue progress reports □ determine when to suspend or terminate the search □ release SAR facilities when assistance is no longer required □ notify accident investigation authorities □ if applicable, notify the State of registry of the aircraft □ prepare a final report.
