Well, a lot of people have never flown in combat, but one could have
deduced from the fact that we were talking about the P-51 Mustang (a
WWII fighter plane) and the "war" part in "war emergency power" that
the most likely application of war emergency power was indeed, um,
during wartime? War, as in, combat?

A lot of aircraft have flown in a lot of wartime, but they didn't do
it at emergency war power. Obviously, more than just wartime is
required to justify it.

Look Anthony, the engine is designed to fly at X power setting without doing
undue harm to itself so the plane can land and fight another day. In combat,
X might not be enough at some moment to get the pilot out of harms way. So
the aircraft is capable of providing X+ which while it will give the pilot
some added power and maybe the chance of saving both himself and the
airframe it will cause the engine to be replaced.

It is very much like the parachute that Cirrus is using today. If they are
used something is going to break but the a pilot has a chance to survive
that they might not have otherwise had.
