C150 Flaps
Hi there, ive just started my PPL training and was out with an instructor a few days back.
Taking off from our home grass strip, he asked me to put 10 degrees of flap on. Then after taking off from a solid runway which was longer she said not to bother.
I realise that on a longer runway you have all the time in the world to generate enough speed to creat lift however im a little unclear as to why, on a shorter runway with more friction from the grass you select 10 degrees of flap as surely it creates drag?
Could someone please clarify this for my newbie mind?!
