WebCessna defines bootstrapping as "The unstable manifold pressure condition that occurs when the wastegate closes at high altitude under low RPM operation." In other words, it is the point that the manifold pressure begins to fall off when the RPM is reduced. WebConversely, if it is pitched for cruise, the static rpm will be low and takeoff will be sluggish. A further consideration is, the Lycoming O-360 is a high compression engine and does not like to be “lugged” — high manifold pressure and low rpm. Which is the condition you would have on takeoff with a fixed, high pitch prop. — Jim
