Longitudinal static stability — is important in determining whether an aircraft will be able to fly as intended. Static stability As any vehicle moves it will be subjected to minor changes in the forces that act on it, and in its speed. * If such a change causes further changes … Wikipedia
Electronic stability control — (ESC) is a computerized technology [1][2] that may potentially improve the safety of a vehicle s stability by detecting and minimizing skids.[3] When ESC detects loss of steering control, it automatically applies the brakes to help steer the… … Wikipedia
Flight dynamics — is the science of air and space vehicle orientation and control in three dimensions. The three critical flight dynamics parameters are the angles of rotation in three dimensions about the vehicle s center of mass, known as pitch , roll and yaw… … Wikipedia
Whammy bar — A whammy bar, tremolo arm/bar, or vibrato arm/bar is a component of a guitar, used to add vibrato to the sound by changing the tension of the strings, typically at the bridge or tailpiece. The whammy bar enables the player to quickly vary the… … Wikipedia
Ultralight trike — An ultralight trike, also known as a flex wing trike, weight shift control aircraft, microlight trike, deltatrike[1] or motorized deltaplane,[2] is a type of powered hang glider using a high performance Rogallo wing coupled to a propeller powered … Wikipedia
Tremolo arm — A tremolo arm or tremolo bar (also called a whammy bar or wang bar ) is a lever attached to the bridge and/or the tailpiece of an electric guitar or archtop guitar to enable the player to quickly vary the tension and sometimes the length of the… … Wikipedia
