"For example, rapid acceleration required moving no less than six levers." Taken from http://en.wikipedia.org/wiki/Lavochkin_La-5

I have read this article and was trying to figure out what the six levers were.
My guess is
Throttle
Pitch
Mixture
Supercharger?
Boost?
Cowl flaps?
Nose-down trim?
Anyone have any input on this one?
