Default More flaps?

I was wondering, after he got on the backside of the power curve and
committed to flight, could he have recovered it by putting out more
flaps?

Cheers


Don't think so. Back side behavior depends on how deep you are into the
back side. There is an area (as in slow flight) as you go into reverse
command where to maintain altitude on the back side you need to apply
power. You can do this until you max the available power. At that point
available power gives way to developing sink rate. Go past that point
and into a sink rate and the only way out is to reduce angle of attack.
This is what many in the flight test community refer to as a "coffin
corner", not of course to be confused with the classic aerodynamic
coffin corner experienced at altitude associated with mach crit vs stall
speed.
