If you use the

In a Cessna if you try to use a zero flap airspeed with flaps 20 you
will wonder why you have to hold it on the ground to keep it from
flying. Having the flaps stuck at 20 is no emergency.



The longer it
takes you to realize it, the closer the trees get.

In a Cessna you will shoot over those trees with no problem.
