Default Stalls??

Why is it so many pilots are afraid of stalls? I see it over an over
when doing flight reviews and checks. Why are pilots so afraid of
flying in the low end of the speed envelope? Isn't that where the
nasty things can happen? Isn't that where a pilot should be
comfortable and competent?
What do you think?


I think that to consider stalls within the confines of the low-speed end of
the envelope is naive at best and dangerous at worst. With 24,000+ hours
you obviously know that, but after skimming through the many (many) replies
to this thread I see scant little, if any, acknowledgement that the stall
occurs at a given angle of attack (AoA), not a SPEED!

You can safely (as in not over-stress the airframe) use full control
deflection from the bottom of the green arc (usually Vs) to Vmo. At Vmo,
full elevator deflection will result in the airframe's maximum certified G
load, right before the stall. IOW, max-G and stall occur simultaneously.
Below Vmo, the wing will stall before max-G. At 1G, the wing stalls at Vs.

Here's something to really fry your noodle: at zero-G, the wing wont stall
(think about it).

My point is, stalls are an aerodynamic phenomena that is tied to the AoA,
not the ASI. I have a CFI, ATPL, aerobatics endorsements, etc, and
several thousand hours too...but all this is basic aeronautical knowledge
that is taught at ab-initio stage. Stalls shouldn't be feared, just
understood, then practised until they are as familiar as any other phase of
flight - right across the speed envelope.

BTW, you haven't lived until you've done accelerated stalls that transition
into accelerated spins! Hoo-har!!
