What is center line thrust?
A design where the propeller thrust line passes through, or very close to, the aircraft's center of gravity. Adding or reducing power on a true CLT design has little effect on pitch, and the design is not subject to a power push over the way a high thrust line design is. Most gyroplanes are not built this way; a high thrust line, paired with a proper stabiliser, is the more common modern layout instead.

That is the whole entry for now. The longer version, with the mechanics and worked examples, is still to be written. See autorotation for how those read once they exist.
