The ideal position for a static port is a position where the local air pressure in flight is always equal to the pressure remote from the aircraft, however there is no position on an aircraft where this ideal situation exists for all angles of attack. When deciding on a position for a static port, aircraft designers attempt to find a position ...
Static wicks on the winglet and aileron of an EasyJet Airbus A319-100. Static wicks, also called static dischargers or static discharge wicks, are devices used to remove static electricity from aircraft in flight. They take the form of small sticks pointing backwards from the wings, and are fitted on almost all civilian aircraft. [1]
[7]: 8 If the center of gravity is aft of the neutral point, the static margin is negative. The greater the static margin, the more stable the aircraft will be. Most conventional aircraft have positive longitudinal stability, providing the aircraft's center of gravity lies within the approved range.
For a stable aircraft, if the aircraft pitches up, the wings and tail create a pitch-down moment which tends to restore the aircraft to its original attitude. For an unstable aircraft, a disturbance in pitch will lead to an increasing pitching moment. Longitudinal static stability is the ability of an aircraft to recover from an initial ...
Qatar Airways announced it was grounding its five Dreamliners. [53] Ethiopian Air was the final operator to announce temporary groundings, of its four Dreamliners. [54] As of January 17, 2013, all 50 of the aircraft were grounded. [54] [55] [56] On January 18, Boeing announced that it was halting 787 deliveries until the battery problem was ...
As all information from the sensors is transmitted electrically, routing of pitot and static pressure lines through the aircraft and associated maintenance tasks is avoided. [ 5 ] In simpler aircraft and helicopters, the air data computers, generally two in number, and smaller, lighter and simpler than an ADIRU, may be called air data units ...

It is one measure of how strongly an aircraft wants to fly "nose first", which is clearly very important. 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 ...
