Almost every turbocharged airplane engine ever built operates "over square"


We're not talking turbocharges airplanes for this one, however I do
understand the over square concept in takeoff, and other operations.
Aside from that, its a relationship that has been established. When
flying at 2200 RPM or so and going full power you run a greater risk
of breaking something than at full pitch (high RPM). This is all I
was trying to say.
