Canadian Beech,
It's the opposite actually, I digged too much. There's a question in XYZ book about larger flap setting and the answer was longer runway is needed and then the other books that I've been reading is saying the opposite.
I'm just getting confuse, I understand that this question can get tricky, larger flap setting will get you airborne sooner but will degrade your climb gradient.
FYI, I hit the books 7 to 9 hours a day for a month now.
Thanks for the advice though.
