Bad place to stall

Suppose you are in the final quarter of a loop maneuver, looking at the
ground. Your speed is high and you are pulling back hard to bring the
plane back to level. Can that result in a stall?

Yup.

Find a V-g diagram for the airplane and you will see where the airspeed
and g-loading intersect.

pull back hard, kick in some rudder and you'll get a neat snap roll.

Once upon a time there was a geology instructor at Western Washington
University who was also an aerobatic pilot. He got hooked up with someone
over in the Middle East (king of Jordan?) and went there to teach him
aerobatics...the Arab was already jet-qualified. He did exactly what you
describe, only on television news. Hard way to watch someone die.

Yes indeed. Low altitude vertical recoveries and the safety issues
associated with them as they relate to the air show demonstration
environment happen to be a specialty of mine. There is an feature article
dealing with what I have to say on exactly this issue in the Feb 2004 issue
of Aeroplane Monthly; "Precision Decision" by Gen Des Barker of the South
African Air Force. You can either obtain a back issue from the publisher or
if you email me back channel, I'll be happy to send a copy of the article to
you on a pdf file. The article deals almost directly with your question as
that relates to flying the P51 Mustang, although it covers a great deal
more.

By "level" I assume you mean no longer losing altitude. There are lots of
videos on the web of people mushing into the ground at the bottom of a loop.
The nose is often pointed up ( a bit). But they're well stalled and still
descending. You can stall at any speed. (Up until the point where you tear
the wings off.)

moo

Yes.

Thanks. That is exactly what I wanted to know. Many pilots tell me
things like, "You can't stall when you're going fast." They're wrong!

Speed has nothing whatsoever to do with stalling. What makes you stall
below the stall speed is that you are continuing to increase the AOA
trying to maintain level flight.
