4 ideas to know cold.
Classic GPWS monitors terrain proximity:
Tip: TAWS uses GPS and a terrain database to look ahead.
A stick shaker warns of approaching stall; a stick pusher pushes the nose down if the stall is reached.
1 excessive descent rate, 2 terrain closure, 3 altitude loss after take-off, 4 unsafe terrain clearance, 5 below glideslope, 6 callouts, 7 windshear.
FDR: flight parameters (≥ 25 h). CVR: crew audio (last 2 h).

Answer: B. ground proximity warning system
It warns of unsafe proximity to terrain.
Answer: D. excessive descent rate
"SINK RATE" / "PULL UP".
Answer: B. altitude loss after take-off or go-around
"DON'T SINK".
Answer: C. unsafe terrain clearance when not in the landing configuration
"TOO LOW GEAR / FLAPS / TERRAIN".
Answer: B. a terrain database and the aircraft position (GPS) to look ahead
Provides forward-looking terrain avoidance.
Answer: B. pull up immediately with maximum thrust
The crew should apply full thrust and pitch to the maximum safe angle.
Answer: A. the weather radar to detect microbursts ahead of the aircraft
Doppler radar detects velocity changes.
Answer: C. pushes the control column forward to reduce the angle of attack at the stall
It is used on aircraft with poor stall characteristics (e.g. T-tail).
Answer: C. flight parameters such as altitude, speed, heading and control positions
At least 25 hours of data are retained on modern FDRs.
Answer: C. orange
Often called "black boxes", but they are bright orange for visibility.
Answer: C. 37.5 kHz
Operates for at least 30 days when immersed.
Answer: D. the flaps, slats, trim or speed brakes are not in the take-off position when the thrust is advanced
Also activated for parking brake set.
