Which items are signaling devices in aircrew survival gear?

• A. Flare/beacon.
• B. GPS receiver.
• C. Radar altimeter.
• D. Radio transceiver.

Answer: (A)

Signaling devices in aircrew survival gear are meant to draw rescuers’ attention by emitting a distress signal that can be detected without relying on normal communications networks. A flare or beacon does exactly that. A flare can be seen by rescuers at long distances, especially at night, providing an immediate visual signal of a location. A beacon, such as an emergency locator beacon or personal locator beacon, transmits a distress signal on dedicated frequencies (often with GPS coordinates) to search-and-rescue services, guiding responders to you.

In contrast, a GPS receiver provides location information to help you navigate or document where you are, but it does not emit a signal. A radar altimeter measures altitude for flight safety, not for signaling rescuers. A radio transceiver enables two-way communication, which can aid in contacting help, but it isn’t primarily a distress signaling device. Therefore, flare or beacon best meets the role of signaling devices in aircrew survival gear.
