Stalls and Thoughts

WrongO againO. The "coffin corner" is an altitude (point on a chart where
the stall speed and Mach come together) with a max power setting. If you go
faster, you get mach buffet. If you go to slow, you stall. If you reduce
power setting, you stall. If you nose over to recover, you mach buffet.
With your example I can see why you're confused.

"Generally"?, "most certainly"?, I'd say "in one case". The other way
around is correct. That is "if you are in the area of reverse command,
you are dragging it in". Notwithstanding that the phrase includes the
notion of approaching and/or landing. The coffin corner is also not on
the back side of the power curve. It is at the asymptote and you can
never get into the back side. That's why it a corner. It is certainly
not referred to as "dragging it in" there. Been there with the best test
pilots in the world in a 747-400 while I was testing the 400. No one has
ever referred to is as that.

You're kidding right?

I believe you are repeating wht I have said. I said that "dragging it in"
generally refers to flying the approach in the area of reverse command or
if you will behind the power curve. This is absolutely correct. Coffin
corner is the area behind the curve where sink rate can't be stopped with
power but requires reduction in angle of attack.
For a perfect example of an aircraft in coffin corner, see the Edwards AFB
accident involving a young AF pilot who got his F100 so deep into coffin
corner behind the curve he couldn't recover the airplane; not enough air
under him to reduce the angle of attack. He applied full burner but
couldn't fly it out on power alone. Reduction of angle of attack was what
he needed and he didn't have the room. THIS is the definition of coffin
corner and it most certainly IS in the area of reverse command.
