Maximum speed for stability characteristics. [7] [9] V FE: Maximum flap extended speed. [7] [8] [9] V FTO: Final takeoff speed. [7] V H: Maximum speed in level flight at maximum continuous power. [7] [8] [9] V LE: Maximum landing gear extended speed. This is the maximum speed at which a retractable gear aircraft should be flown with the landing ...
Both Tu-116 and Tu-142 claim higher maximum speeds. 5 February 1952: Flight Lieutenant Edward Powles: 690: 1,110.447: Supermarine Spitfire PR.XIX PS852: Reached (Mach 0.96) during an emergency dive while carrying out spying flights over China, the highest speed ever recorded for a piston-engined aircraft (though not in level flight). [68] 14 ...
Table II-5-1-2 Aircraft approach categories do not change during day-to-day operation. To change an aircraft's category, an aircraft must be re-certified with a different maximum landing mass. [1]: II-5-1-3 Pilots may not use a lower category than the one certified, but may choose to use a higher category for higher speed approaches. [2]
At a glance, the pilot can determine a recommended speed (V speeds) or if speed adjustments are needed. Single and multi-engine aircraft have common markings. For instance, the green arc indicates the normal operating range of the aircraft, from V S1 to V NO. The white arc indicates the flap operating range, V SO to V FE, used for approaches ...
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.
Graph of altitude/speed region envelope for Lockheed U-2 depicting coffin corner. Coffin corner (also known as the aerodynamic ceiling [1] or Q corner) is the region of flight where a fast but subsonic fixed-wing aircraft's stall speed is near the critical Mach number, at a given gross weight and G-force loading. In this region of flight, it is ...
Commercial flights typically travel between 480 to 575 mph speeds, according to Flex Air Flight School. Eddie Sheerr, a meteorologist with NTV News in Canada, said in a post on X that the planes ...
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. While the exact numbers will vary widely from aircraft to aircraft, the nature of this relationship is typically the same; plotted on a graph of speed (x-axis) vs ...
