Document Summary
At this point in the course, we"ll be discussing various aspects of aircraft flight control, for both manual (pilot-in-the-loop) and automatic flight control systems (afcs), and observe potential tie-ins to our general coverage of aircraft performance. 1 to 4 provide a number of pertinent attitude and direction angles, and associated parameters, that would be of interest for flight control and navigation. As we proceed, we"ll refer to these figures as required. Elevators (or forward-positioned canards) provide a pitching moment )m about the aircraft"s centre-of-gravity (c. g. Ailerons provide a rolling moment )l" about the x-axis, and rudders provide a yawing moment. These moments are needed to move the aircraft"s attitude to a desired position (pitch angle 2 , roll angle n , yaw or airframe heading angle r ) as referenced to the earth (as per figs. Consider the equations of angular motion that govern the above events. R,q,p are the angular rate accelerations about the aircraft"s respective axes.
