fokker100 take off flap affects on performance
Having just been on an Austrian Fokker 100 Birmingham to Innsbruck I noticed no flap (trailing edge ) at Birmingham Take off, but on take off at Innsbruck there was quite a bit out ( but not drooping down , ie like a horizontal wing extension ) somewhere between 5 and 10????? guessing that Innsbruck needs it because of climb out clearance or is it runway length just wondered how the two settings affected say V1 VRotate and climbout Rate of ascent or was runway length a factor I'm assuming aircraft loading was fairly similar ( no empty seats ) and a fairly full fuel load for that journey .
