Rich, another part of the equation,just to confuse you further, if you happen to be flying an aircraft with a big ol` recip (R 1820, R2800, R3350), a real danger is an overboost. These engines are equipped with a one or two stage supercharger. On takeoff if you didn`t push the prop(s) up (flat pitch), it would be possible..no for certain, you could apply too much power for the prop setting and damage the engine(s). Back in the dark ages, when I was a cadet going through Navy flight training,flying the North American T28B, the Navy, with it`s infinate wisdom, declared that an overboost would be an automatic "down" (in other words, a failure for that flight). Of course the cadets, on solo flights, if they happened to overboost an engine didn`t report it. The consequence was a rash of engine failures.Glad I switched to jets...less levers to push and pull.
