ANSWERS TO KHUN PAUL'S AVIATION QUIZZ

1. Over Vne 112 kts see Page 18. 2. False 3. Yes. Weight has no effect on glide ratio. 4. Lower. If a clean wing stalls at 15 degrees, the flapped portion stalls about 12 degrees. 5. Impossible to recover from a stall. 6. Best range see Page 18 and question 15. 7. Over read. See Page 18 8. ASI under reads higher, over reads lower altitude. VSI shows no reading. Altimeter reads height when blockage occurred. 9. True. Ground effect increases lift. 10. 9 knots – see Page 18 11 Manoeuvring speed. It varies with weight.12. 50% - see Page 18 13. Laminar flow wings and thrust not drag from the cooling design 14. Give way and circle 15. True. Most efficient lift/drag typically 4 degrees angle of attack. We relate this to a given airspeed. 16. 352 Nm. See Page 18. 19-14 = (5x60) plus 57-05 = (52) 17. Fuel Radio Engine Direction Altitude 18. Ubon 30^th 12.50h wind 15 kts @ 200. 170 varying 250 deg. Vis 10km. Rain. Cloud -Scattered 1,800 CuNim -Scattered 7,000 -Broken 10,000. 16/30 temp/dew point. QNH 1004. No significant weather. 19. Better radio, visibility, engine out options. 20. 6 % 21. Icing and shock cooling  22. True. 23. Control surface flutter. Sudden turbulence. 24. Increase approach speed and expect sink or rotor. 25. Increased downwash angle changing the tail’s angle of attack is more powerful. 26. 5,500 Page 19 27. At least 1,000 above Page 19 28. 5 km Page 19 29 Sqwawk 4404  30. You are in between  low and high pressure areas. 31. 20 seconds 32. The weather will probably be much better over the sea. 33. Close to stall speed and possibility of power-on departure stall. 34 1,500m horizontal and 300m vertical. Page 19  35. 210 at 15 kts (free wind 30 degrees veer and 50% stronger)
