englishal asked WHY was there no mention of a stage of flap for S/F? for the AA5 The aeroplane could handle a much shorter strip with flap, so it seems daft not to use them??
For the answer to that may I steer you towards what the Grumman Owners Club’s Safety Director once had to say on this
RE: Why "no flaps" for takeoff? Basically what I believe he is saying is if you use the correct S/F procedure for the Grumman and rotate to the optimum AOA , which in a Grumman is unnaturally high, zero flaps will give you the shortest take off roll.
The flaps on Take Off debate within the Grumman Community is long running and if you want to spend a couple of evenings going though all 775 matches on the subject go to the Grumman Gang archives site
