The Lockheed SR-71 Blackbird holds the official Air Speed Record for a crewed airbreathing jet engine aircraft with a speed of 3,530 km/h (2,190 mph). The record was set on 28 July 1976 by Eldon W. Joersz and George T. Morgan Jr. near Beale Air Force Base, California, USA.
Maximum landing gear operating speed. This is the maximum speed at which the landing gear on a retractable gear aircraft should be extended or retracted. [7] [9] [20] V LOF: Lift-off speed. [7] [9] V MC: Minimum control speed. The minimum speed at which the aircraft is still controllable with the critical engine inoperative. [7]
The auction ended without a sale. [21] In January 2004, a seaworthy 16,000-ton Brazilian aircraft carrier Minas Gerais, formerly the British HMS Vengeance, was listed. The auction was removed when eBay determined that the vessel qualified as ordnance, even though all weapons systems had been removed. [22]
The Guinness Book of World Records lists the Soviet Tupolev Tu-95 bomber and its derivatives (Tu-114 and Tu-142) as "the fastest propeller-driven aircraft in standard production form", with a maximum cruise speed of 925 km/h (575 mph; 499 kn) or Mach 0.82.
All fixed-wing aircraft have a minimum speed at which they can maintain level flight, the stall speed (left limit line in the diagram). As the aircraft gains altitude the stall speed increases; since the wing is not growing any larger the only way to support the aircraft's weight with less air is to increase speed.
The concept of maximum operating maneuvering speed was introduced to the US type-certification standards for light aircraft in 1993. [1] [6] The maximum operating maneuvering speed is selected by the aircraft designer and cannot be more than , where V s is the stalling speed of the aircraft, and n is the maximal allowed positive load factor.
Airspeed is commonly given in knots (kn). Since 2010, the International Civil Aviation Organization (ICAO) recommends using kilometers per hour (km/h) for airspeed (and meters per second for wind speed on runways), but allows using the de facto standard of knots, and has no set date on when to stop.
This aircraft attained a maximum speed of Mach 2.19 and set a world record for a small closed course in 1959. According to the Fédération Aéronautique Internationale , the aircraft held the flight airspeed record from 5 to 31 October of 1959, with a speed of 1,441.6 mph (2,320 km/h) attributed to Maj. André Turcat .
