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.
An increase in weight increases the stall speed of the aircraft. Therefore, the landing approach speed increases as the aircraft's weight increases. The kinetic energy ( 1 / 2 mV 2) that has to be dissipated to stop an aircraft is a function of the mass of the aircraft and the square of its speed at touchdown. The kinetic energy ...
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]
At final approach, the aircraft's forward speed was 220 knots (250 mph; 410 km/h) and it had a sink rate of 1,850 feet per minute (9.4 m/s), while a safe landing would require 140 knots (160 mph; 260 km/h) forward speed and 300 feet per minute (1.5 m/s) sink rate. Moments before landing, the roll to the right suddenly worsened significantly and ...
Since commercial aircraft development is normally funded by the aircraft manufacturer and/or private investors, the certifying agency does not have a stake in the commercial success of the aircraft. These civil agencies are concerned with the aircraft's safety and that the pilot's flight manual accurately reports the aircraft's performance.
The aircraft was operating from Shanghai Hongqiao International Airport. Upon landing, the aircraft rolled down the whole length of the runway before plunging into the bay where it was completely submerged except for the cockpit. An excessive approach and landing speed were pointed out as probable cause of the accident. [65]
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.
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]
