2. Aircraft dynamic modes - Wikipedia

   The period is usually on the order of 3–15 seconds, but it can vary from a few seconds for light aircraft to a minute or more for airliners. Damping is increased by large directional stability and small dihedral and decreased by small directional stability and large dihedral.

4. Autopilot - Wikipedia

   en.wikipedia.org/wiki/Autopilot

   A stability augmentation system (SAS) is another type of automatic flight control system; however, instead of maintaining the aircraft required altitude or flight path, the SAS will move the aircraft control surfaces to damp unacceptable motions. SAS automatically stabilizes the aircraft in one or more axes.

5. Stability derivatives - Wikipedia

   en.wikipedia.org/wiki/Stability_derivatives

   Stability derivatives, and also control derivatives, are measures of how particular forces and moments on an aircraft change as other parameters related to stability change (parameters such as airspeed, altitude, angle of attack, etc.). For a defined "trim" flight condition, changes and oscillations occur in these parameters.

6. Guidance, navigation, and control - Wikipedia

   en.wikipedia.org/wiki/Guidance,_navigation,_and...

   Guidance, navigation and control (abbreviated GNC, GN&C, or G&C) is a branch of engineering dealing with the design of systems to control the movement of vehicles, especially, automobiles, ships, aircraft, and spacecraft. In many cases these functions can be performed by trained humans.

7. Flight control modes - Wikipedia

   en.wikipedia.org/wiki/Flight_control_modes

   A flight control mode or flight control law is a computer software algorithm that transforms the movement of the yoke or joystick, made by an aircraft pilot, into movements of the aircraft control surfaces. The control surface movements depend on which of several modes the flight computer is in.

8. Gyroscopic autopilot - Wikipedia

   en.wikipedia.org/wiki/Gyroscopic_Autopilot

   The key feature of the gyroscopic stabilizer apparatus was that it incorporated a gyroscope to regulate the control surfaces of the aircraft. [1] Lawrence Sperry managed to design a smaller and lighter version of a gyroscope, [1] and the device was integrated into an aircraft's hydraulic control system. Using a negative feedback loop, the ...

   Cockpit controls and instrument panel of a Cessna 182D Skylane. Generally, the primary cockpit flight controls are arranged as follows: [2] A control yoke (also known as a control column), centre stick or side-stick (the latter two also colloquially known as a control or joystick), governs the aircraft's roll and pitch by moving the ailerons (or activating wing warping on some very early ...
