An old rule-of-thumb I remember has it that aligning the flap with a

Never heard it but it sounds like a good bush piloty sort of thing to do.


My flight instructor, a former drug-smuggler, taught me that very
technique.


The most lift is always gained with the most flaps.

I try to shy away from the use of the word "always". There are some
aircraft that use flaps for their induced drag. An example is a glider with
large span 90 degree flaps. As an owner of such a craft I can testify that
increased lift is not associated with flap setting greater then 40 degrees.
Setting beyond 45 definitely exist only for the drag they create.

Really?

Even if true, you sometimes end up picking up drag faster than increased
lift at extreme flap settings, depending on the aircraft.

On your typical Cessna 152, 172, 182 206, etc the most lift for the
least drag is approx 20 degrees. Flaps at 40 degrees gives you the most
lift but also more drag than at 20 degrees. Just depends on what you're
trying to accomplish. The first 20 years of Bonanza production there
wasn't a flap indicator in the aircraft, don't have one in mine. The
factory put a stripe that you could line up with the trailing edge of
the wing to get 20 degrees. Those disappear with the first paint job.

I'll bet there's a Gummint regulation that sez you can't hide that stripe.

I re-marked mine with a Sharpie.
