If the AB is reduced to
minimum AB, the engine would actually be dragging on
the engine mounts at high Mach numbers
Isn't this case just the plane slowing down so the dragging on the mounts is just an unbalanced phase until new equilibrium?
Further reduction
of engine thrust below military power will result in no
propulsive thrust on the aircraft
Isn't this even more slowing down to an even lower speed?
