At low speeds, the forward wing will stall first, causing the nose to fall, increasing air speed and automatically exiting a stall. The BlackFly has a...

wing centre of gravity is close to the hang point and, at the trim speed, the wing will fly "hands off" and return to trim after being disturbed. The...

should occur to minimize fuel consumption. Performance optimization allows the FMS to determine the best or most economical speed to fly in level flight...

Amanita muscaria, commonly known as the fly agaric or fly amanita, is a basidiomycete of the genus Amanita. It is a large white-gilled, white-spotted...

Fly-by-wire (FBW) is a system that replaces the conventional manual flight controls of an aircraft with an electronic interface. The movements of flight...

A fly-killing device is used for pest control of flying insects, such as houseflies, wasps, moths, gnats, and mosquitoes. A flyswatter (or fly-swat, fly...

In aviation, V-speeds are standard terms used to define airspeeds important or useful to the operation of all aircraft. These speeds are derived from...

sources said Lockheed Martin was developing an airplane able to fly six times the speed of sound or Mach 6 (4,000 mph; 6,400 km/h; 3,500 kn) for the Air...

A fly-in, also called an aviation meet, is a pre-arranged gathering of aircraft, pilots and passengers for recreational and social purposes. Fly-ins may...

rotational speed of the rotor is constant; reducing it at lower flight speeds can reduce fuel consumption and enable the aircraft to fly more economically...

500-foot (760 m) altitude and 90-mile-per-hour (140 km/h) speed needs about 60 horsepower (45 kW) to fly straight and level. The C150 is normally equipped with...

Supersonic speed is the speed of an object that exceeds the speed of sound (Mach 1). For objects traveling in dry air of a temperature of 20 °C (68 °F)...
