  2. Static wick - Wikipedia

    en.wikipedia.org/wiki/Static_Wick

    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]

  3. Longitudinal stability - Wikipedia

    en.wikipedia.org/wiki/Longitudinal_stability

    For a tailless aircraft, the neutral point coincides with the aerodynamic center, and so for such aircraft to have longitudinal static stability, the center of gravity must lie ahead of the aerodynamic center. [13] For missiles with symmetric airfoils, the neutral point and the center of pressure are coincident and the term neutral point is not ...

  4. Lofting coordinates - Wikipedia

    en.wikipedia.org/wiki/Lofting_coordinates

    Two points on a fuselage at waterline 100/fuselage station 93 and waterline 101/fuselage station 276. Lofting coordinates are used for aircraft body measurements. The system derives from the one that was used in the shipbuilding lofting process, with longitudinal axis labeled as "stations" (usually fuselage stations, frame stations, FS), transverse axis as "buttocks lines" (or butt lines, BL ...

  5. Trailing cone - Wikipedia

    en.wikipedia.org/wiki/Trailing_Cone

    It does this by giving an accurate measurement of the ambient atmospheric pressure (static pressure) well clear of the aircraft's fuselage. The trailing cone system trails at least one fuselage length behind the aircraft (SpaceAge Control) via a high-strength pressure tube. Static pressure is measured forward of the cone by several static ports.

  6. Center of gravity of an aircraft - Wikipedia

    The move compromised the aircraft's balance to the point that control of the aircraft was lost. [6] In July 2013, a de Havilland Canada DHC-3 Otter departed Soldotna, Alaska, stalled after rotation and crashed 2,300 ft (700 m) away from its brake-release point as it was overloaded by 418 lb (190 kg) and its CG was well aft of the rear limit ...

  7. 2013 Boeing 787 Dreamliner grounding - Wikipedia

    en.wikipedia.org/wiki/2013_Boeing_787_Dreamliner...

    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 ...

  8. Stability derivatives - Wikipedia

    en.wikipedia.org/wiki/Stability_derivatives

    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 ...

  9. Ground effect (aerodynamics) - Wikipedia

    en.wikipedia.org/wiki/Ground_effect_(aerodynamics)

    When an aircraft flies at or below approximately half the length of the aircraft's wingspan above the ground or water there occurs an often-noticeable ground effect. The result is lower induced drag on the aircraft. This is caused primarily by the ground or water obstructing the creation of wingtip vortices and interrupting downwash behind the ...
