Answers

1. POH (Pilot Operating Handbook) — binding; values vary per aircraft type.
2. 79 KIAS (C172).
3. Odd thousand ft + 500 → 5500, 7500, 9500 ft etc.
4. 500 ft AAL for VFR; 1000 ft AAL for IFR.
5. Gas, Undercarriage, Mixture, Prop, Switches/Seatbelts — pre-landing check.
6. 15 kt (max demonstrated crosswind C172).
7. Mixture IDLE CUT-OFF immediately (cuts fuel).
8. Fresh fuel reignites the fire — restart attempt is dangerous.
9. Master switch OFF first — all circuits cut.
10. 4-6 hours with normal breathing; 1 h with 100% O₂; 20 min hyperbaric.
11. Fly straight ahead, max 30° turn for obstacles, NO turn back to field.
12. 65 KIAS (Vbg C172).
13. Size, Slope, Surface, Surroundings, Sun, Spectators.
14. At least 50 NM lateral distance.
15. RVR < 600 m typically (or before CAT II/III approach).
16. Immediate go-around with throttle FULL, pitch to Vy or stick-shaker, configuration unchanged.
17. 1500 m ground visibility (800 m for helicopter).
18. 5 hours of night flight training (3 h dual + 1 h cross-country + 5 solo take-offs/landings).
19. MTOM ≥ 136,000 kg (300,000 lb).
20. About 2900 ft AGL (flock of Canada geese, both engines flameout).
21. EU 965/2012 Air Operations.
22. Carriage of dangerous goods.
23. −43 °C (very low, hence easily flammable).
24. > 50 NM distance from coast.
