"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.
