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 ...
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]
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]: 92 If the center of gravity is forward of the neutral point, the static margin is positive. [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 ...
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 ...
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 ...
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 ...
During takeoff, ground effect can cause the aircraft to "float" while below the recommended climb speed. The pilot can then fly just above the runway while the aircraft accelerates in ground effect until a safe climb speed is reached. [2] For rotorcraft, ground effect results in less drag on the rotor during hovering close to the ground. At ...
