Flapless Landings Aim • To learn the principles and considerations of conducting a safe approach without using flaps Application • Flapless landings • When there is a flap system failure • In very gusty conditions • To land at high speed Overview • Revision • Definitions • Principles / Considerations • Air Exercise • Airmanship Revision • Effect of Power and/or flap on the descent profile Without Power or Flap L D W Without Power, With Flap L D W With Power, Without Flap L D W T Definitions Flapless landing • A landing that is conducted safely without the use of flaps Principles / Considerations Compared to a normal approach to land, a flapless approach will have: – A flatter flight path, due to less drag – Higher approach speeds, to maintain a safe margin over the stall speed – Higher nose attitude to maintain sufficient angle of attack – Reduced forward visibility – Minimal flare, but longer float (due to more airspeed and less drag – A longer landing run Air Exercise The circuit is conducted as normal, except for the speed! Glide Approach Normal Approach Flapless Approach 1200 rpm 75 kt 70 kt Expect more float Avoid excess hold-off 65 kt Air Exercise • Nose attitudes Airmanship • Lookout • Thorough Checks • Avoid high-nose attitude on touchdown because of possible tail strike • Will require longer hold-off • If in doubt – go around • Correct handover/takeover procedure作者: 猪也能飞 时间: 2013-10-28 19:18:07
