axis of pitch
41Controllable pitch propeller — A controllable pitch propeller (CPP) or variable pitch propeller is a type of propeller with blades that can be rotated around their long axis to change their pitch. If the pitch can be set to negative values, the reversible propeller can also… …
42y-axis — i. The lateral axis of the aircraft about which an aircraft pitches. Also called the pitch axis, normal axis, z axis, and yawing axis. ii. A vertical two dimensional system of rectangular coordinates. The reference line on which distances above… …
43feathering axis — The axis about which the pitch angle of a helicopter rotor blade is varied. The feathering axis is the same as a spanwise axis …
44angle of pitch — the angle between two planes one of which includes the lateral axis of an airplane and the direction of the relative wind and the other of which includes the lateral and the logitudinal axes that in normal flight is measured between the… …
45propeller pitch — The acute angle between the chord of a propeller and a plane perpendicular to the axis of rotation. The three main pitch angles are coarse, fine, and feathered …

47angle of pitch — Aeron. the acute angle between the longitudinal axis of an aircraft or spacecraft and the direction of the wind relative to the vehicle. * * * …
48vehicle pitch angle — the angle between the vehicle x axis and the ground plane …
49three-axis autopilot — An autonomous flight control system that has full authority in the pitch, roll, and yaw. See automatic pilot …
50geometrical pitch — noun : the distance an element of an airplane propeller would advance in one revolution if it were moving along a helix having an angle equal to that between the chord of the element and a plane perpendicular to the propeller axis …
