Pitching moment due to pitch rate - the pitch damping term, this is always negative. Since the tail is operating in the flowfield of the wing, changes in the wing incidence cause changes in the downwash, but there is a delay for the change in wing flowfield to affect the tail lift, this is represented as a moment proportional to the rate of ...
A commonly used solution to pitch-up in modern combat aircraft is to use a control-canard. [9] Another modern solution to pitch-up is the use of slats. When slats are extended they increase wing camber and increase maximum lift coefficient. [10] Pitch-up is also possible in aircraft with forward-swept wings as used on the Grumman X-29. With ...
Flight dynamics in aviation and spacecraft, is the study of the performance, stability, and control of vehicles flying through the air or in outer space. [1] It is concerned with how forces acting on the vehicle determine its velocity and attitude with respect to time.
The longitudinal stability of an aircraft, also called pitch stability, [2] refers to the aircraft's stability in its plane of symmetry [2] about the lateral axis (the axis along the wingspan). [1] It is an important aspect of the handling qualities of the aircraft, and one of the main factors determining the ease with which the pilot is able ...
The aircraft struck the ground at a speed of 340 knots, causing the death of the three crew members and all fifteen passengers. [ 5 ] In the 1975 Tan Son Nhut C-5 accident , USAF C-5 68-0218 with flight controls damaged by failure of the rear cargo/pressure door, encountered phugoid oscillations while the crew was attempting a return to base ...
The aircraft crashed shortly after takeoff due to an excessive rate of turn on the part of the crew during the climb. January 19, 1988 9 7 8 Trans-Colorado Airlines Flight 2286: Bayfield: Colorado: Fairchild Swearingen Metroliner: The aircraft crashed during approach due to descent below the approach profile during a rapid descent.

Blade pitch acts much like the gearing of the final drive of a car. Low pitch yields good low speed acceleration (and climb rate in an aircraft) while high pitch optimizes high speed performance and fuel economy. It is quite common for an aircraft to be designed with a variable-pitch propeller, to give maximum thrust over a larger speed range ...
An attitude and heading reference system (AHRS) consists of sensors on three axes that provide attitude information for aircraft, including roll, pitch, and yaw. These are sometimes referred to as MARG (Magnetic, Angular Rate, and Gravity) [ 1 ] sensors and consist of either solid-state or microelectromechanical systems (MEMS) gyroscopes ...
