FAA Aircraft Dispatcher (ADX)Regulations (Part 121)Easy
A Part 121 certificate holder is operating a turbine-powered airplane with 25 passenger seats. Under 14 CFR 121.354, which of the following is required equipment?
- AA cockpit voice recorder (CVR).
- BA Terrain Awareness and Warning System (TAWS).
- CA crewmember interphone system.
- DA flight data recorder (FDR).
Show answer & explanationAnswer & explanation
Correct answer: B. A Terrain Awareness and Warning System (TAWS).
14 CFR 121.354 requires that no person may operate a turbine-powered airplane with 10 or more passenger seats unless it is equipped with a TAWS.
Why the other options are wrong
- A. CVR requirements (121.359) are based on aircraft type and date of manufacture, not solely on passenger seat count.
- C. A crewmember interphone system is required under 121.319, but not specifically tied to the TAWS requirement.
- D. FDR requirements (121.343) are based on aircraft type and date of manufacture, not solely on passenger seat count.
TAWS Requirement (121.354)
14 CFR 121.354 mandates that all turbine-powered airplanes configured with 10 or more passenger seats must be equipped with a Terrain Awareness and Warning System (TAWS).
- Applies to turbine-powered airplanes.
- Triggered by 10 or more passenger seats.
- Enhances flight safety by alerting pilots to terrain hazards.
Memory trick: Ten seats or more, turbine power, TAWS must soar.
