A newbies impression of the 109 and spit

[IvanK]

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

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

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.
