I hate the expression, "bleeding energy"....

There is not such thing in aircraft performance. There is only sustainable performance and instantenous performance.

If it the performance is sustainable then the aircraft can achieve that performance until it runs out of fuel.

There is not an aircraft in existance that can sustain instantenous performance so it is just silly to talk about it as "bleeding energy". In fact, the generally speaking aircraft with the higher braking forces will win the instantenous turn competition. All aircraft at the same angle of bank and velocity will make the same turn.

"I hate the expression, "bleeding energy"....

So when a manoeuver diagrams have values of negative Specific excess power (Ps) and these are used to compare sustained turn performance and energy bleed rates between 2 aircraft what do you call it ?

The worlds fighter pilots use the term "Energy Bleed' everyday. ...... but I guess they are all misguided dealing with the real world rather than theoretical commentary.
