Wolfgang states: "If the airframe can't get back in the envelope, then the airframe needs to be fixed."
There are lots of historical examples to the contrary, like the F4 Phantom. Once in a flat spin, the plane was unrecoverable from any altitude. "Stick Forward, Ailerons and Rudder Neutral, If not Recovered, Maintain Full Forward Stick and Deploy Drag Shoot" were not enough.
Yet the F4 was the work horse fighter for the Navy, Air Force, Marines, and hosts of allies for decades. And it was fast, over Mach II.
Yet, you stayed far far away from "departing" -- high angle of attack, stick one way and the rudder the other.....
Most advanced stalls in IVP are recoverable, given 10,000 feet or so.
But unlike the F4, most of our IVPs are not equipped with Martin-Baker ejection seats.
The F4 never got fixed. The IVP got "fixed." It's called the "ES," with larger differently shaped wings and fixed gear, that became the Columbia/Cessna.
The "fix" was a series of tradeoffs that IMHO made it a less desirable plane -- slower, fixed gear, non-pressurized.
I'll happily keep the un-fixed version of the IVP myself, thank you.

Knowing where the edges of the envelope are and how
to get beck in the envelope should be required.
If the airframe can't get back in the envelope,
then the airframe needs to be fixed.

David, I have no problem
with anyone who wants to explore the “envelope” of his/her airplane. However,
I take great exception to you grounding me because I might choose to not get
as near to the edge as you. Lynn

.6 I agree 100%
also. If you don’t
know what the incipient stall feels like in the stick and the airframe you
should not be flying the Legacy or 320’s. (Not knowing
this is the single biggest killer of Lancair
pilots.) David
