CFC Search & Rescue Coordination 4 — Questions and Answers
Question 1: What is the correct phraseology for a flight communicator to acknowledge a distress call?
- [Callsign] MAYDAY, I read you, help is coming
- [Callsign] DISTRESS ACKNOWLEDGED, standby for instructions
- [Callsign] MAYDAY, [your station], received MAYDAY, [time], [your callsign] (Correct answer)
- MAYDAY [callsign] this is [station], copy your distress
Correct answer: [Callsign] MAYDAY, [your station], received MAYDAY, [time], [your callsign]
Standard ICAO phraseology for acknowledging a MAYDAY is to repeat the distressed station's callsign, identify your station, state 'received MAYDAY,' give the time, and end with your callsign.
Question 2: In the IAMSAR Manual framework, which body is responsible for providing overall coordination of SAR services within a Search and Rescue Region (SRR)?
- Mission Coordinator (MC)
- Rescue Coordination Centre (RCC) (Correct answer)
- On-Scene Coordinator (OSC)
- Sub-Regional Coordination Centre (SRCC)
Correct answer: Rescue Coordination Centre (RCC)
The Rescue Coordination Centre (RCC) is responsible for the overall coordination of SAR services within its designated Search and Rescue Region.
Question 3: A 406 MHz ELT provides which key advantage over a 121.5 MHz ELT?
- Longer battery life and lower cost
- Encoded identification allowing near-instant distress alert via COSPAS-SARSAT (Correct answer)
- Ability to transmit voice communications
- Compatibility with older aircraft receivers
Correct answer: Encoded identification allowing near-instant distress alert via COSPAS-SARSAT
406 MHz ELTs transmit a unique encoded identification that is processed by the COSPAS-SARSAT satellite system, enabling near-instant alert and precise position determination.
Question 4: What is 'sweep width' in SAR search planning?
- The physical width of the search aircraft's wingspan
- The effective lateral range at which a sensor can detect the search object with 50% probability (Correct answer)
- The total width of the assigned search area
- The distance between parallel search tracks
Correct answer: The effective lateral range at which a sensor can detect the search object with 50% probability
Sweep width is the effective lateral range at which a sensor detects the search object 50% of the time, used to calculate optimal track spacing.
Question 5: A flight communicator coordinating a water survival situation should consider which factor FIRST when estimating survival time?
- Wind speed and direction
- Water temperature and risk of hypothermia (Correct answer)
- Distance from the nearest shoreline
- Availability of life rafts or flotation devices
Correct answer: Water temperature and risk of hypothermia
Water temperature is the primary factor in survival time estimation because hypothermia is the leading cause of death in water survival situations.
Question 6: When coordinating SAR with military assets, a flight communicator must ensure that:
- Military aircraft always assume the OSC role
- Appropriate coordination is established through the Joint Rescue Coordination Centre (JRCC) or military liaison (Correct answer)
- Civilian aircraft yield all airspace to military SAR aircraft
- Military SAR operations are reported separately to ICAO
Correct answer: Appropriate coordination is established through the Joint Rescue Coordination Centre (JRCC) or military liaison
When military SAR assets are involved, coordination must be established through the JRCC or appropriate military liaison to ensure unified command and communication.
Question 7: Which document serves as the primary international guide for organizing and conducting SAR operations?
- ICAO Annex 2 — Rules of the Air
- IAMSAR Manual (International Aeronautical and Maritime Search and Rescue) (Correct answer)
- FAA Order 7110.65 — Air Traffic Control
- IMO SOLAS Convention Chapter V
Correct answer: IAMSAR Manual (International Aeronautical and Maritime Search and Rescue)
The IAMSAR Manual is the primary international reference for organizing and providing SAR services and coordinating SAR operations.
