EAWS Aviation Survival and Egress Systems 2 — Questions and Answers
Question 1: What is the minimum altitude at which an ejection seat is typically effective for a zero-zero ejection?
- 0 feet and 0 knots (zero-zero capable) (Correct answer)
- 500 feet AGL
- 1,000 feet AGL
- 200 knots airspeed only
Correct answer: 0 feet and 0 knots (zero-zero capable)
Modern zero-zero ejection seats are designed to safely eject aircrew at zero altitude and zero airspeed on the ground, providing full parachute deployment.
Question 2: What is the purpose of a 'PRC-90' or 'PRC-112' survival radio?
- Fire control communications
- Encrypted tactical communications
- Personnel recovery and search and rescue communications (Correct answer)
- Air traffic control communications
Correct answer: Personnel recovery and search and rescue communications
The PRC-90 and PRC-112 are emergency radios used by downed aircrews for personnel recovery communications with search and rescue forces.
Question 3: When donning an anti-exposure suit, which area must always be checked for airtightness?
- Knee joints
- Neck and wrist seals (Correct answer)
- Ankle zippers
- Chest pocket closures
Correct answer: Neck and wrist seals
The neck and wrist seals of an anti-exposure (immersion) suit must be checked for airtightness to ensure the suit provides thermal protection in cold water.
Question 4: What is the purpose of a personal locator beacon (PLB)?
- Track aircraft fuel consumption
- Automatically transmit distress signals to search and rescue satellites (Correct answer)
- Monitor aircrew vital signs
- Control drone aircraft
Correct answer: Automatically transmit distress signals to search and rescue satellites
A PLB automatically transmits a distress signal on emergency frequencies to COSPAS-SARSAT satellites, enabling rescuers to locate downed personnel.
Question 5: What does 'HEED' stand for in aviation survival equipment?
- High Explosive Egress Device
- Helicopter Emergency Egress Device (Correct answer)
- Hazardous Equipment Emergency Disposal
- High Endurance Emergency Device
Correct answer: Helicopter Emergency Egress Device
HEED (Helicopter Emergency Egress Device) is a small self-contained underwater breathing apparatus that provides breathable air during helicopter underwater escape.
Question 6: Which signal mirror technique is used to aim reflected sunlight at a rescue aircraft?
- Hold mirror behind your back
- Use the aim-through hole to align reflection with target (Correct answer)
- Flash mirror randomly to attract attention
- Cover mirror until aircraft is within 500 feet
Correct answer: Use the aim-through hole to align reflection with target
The aim-through hole technique allows the survivor to direct reflected sunlight precisely at a rescue aircraft or ship by aligning the reflection through the sighting hole.
