  2. Flight airspeed record - Wikipedia

    en.wikipedia.org/wiki/Flight_airspeed_record

    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 ...

    en.wikipedia.org/wiki/V_speeds

    Maximum landing gear extended speed. This is the maximum speed at which a retractable gear aircraft should be flown with the landing gear extended. [7] [8] [9] [20] V LO: 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 ...

  4. Airspeed indicator - Wikipedia

    en.wikipedia.org/wiki/Airspeed_indicator

    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 ...

  5. Flight envelope - Wikipedia

    en.wikipedia.org/wiki/Flight_envelope

    General aviation aircraft have very small flight envelopes, with speeds ranging from perhaps 50 to 200 mph, whereas the extra power available to modern fighter aircraft result in huge flight envelopes with many times the area. As a trade-off however, military aircraft often have a higher stalling speed.

  6. Indicated airspeed - Wikipedia

    en.wikipedia.org/wiki/Indicated_airspeed

    Ground speed is just a pilot aid to estimate if the flight is on time, behind or ahead of schedule. It is not used for takeoff and landing purposes, since the imperative speed for a flying aircraft always is the speed against the wind. The Machmeter is, on subsonic aircraft, a warning indicator.

  7. Coffin corner (aerodynamics) - Wikipedia

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

    These curves typically intersect at some altitude higher than the maximum permitted altitude for the aircraft. This intersection is the coffin corner, or more formally the Q corner. [3] The above explanation is based on level, constant speed, flight with a given gross weight and load factor of 1.0 G. The specific altitudes and speeds of the ...

    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 ...

  9. Cessna 441 Conquest II - Wikipedia

    en.wikipedia.org/wiki/Cessna_441_Conquest_II

    The Cessna 441 Conquest II is the first turboprop powered aircraft designed by Cessna and was meant to fill the gap between their jets and piston-engined aircraft. It was developed in November 1974, with the first aircraft delivered in September 1977. It is a pressurized, 8–9 passenger turbine development of the Cessna 404 Titan.
