ELEVATOR, a hinged moveable part on the trailing edge of the horizontal stabilizer for airplane pitch (nose up and nose down) control.
升降舵，铰连在水平安定面后缘上的可动部件。用以操纵飞机的俯仰运动(机头朝上及朝下)。
This article clears the measuring coupling relationship between horizontal azimuth and pitch angles by detailed mathematical deduction.
本文通过详细的数学推演，厘清了水平方位角与俯仰角测量耦合的关系。
Pitch axis - Horizontal or lateral axis, passes through the airplane from one side to the other - nose up and nose down control is by elevators (and stabilizer for trim).
俯仰轴—又称水平轴或横轴。由飞机的一侧通向另一侧。飞机绕此轴转动即造成机首的俯与仰。俯仰控制是由升降舵来达成的，水平安定面则为配平之用。
