The lowest NOE flying is by helicopters because they have lower speeds and more maneuverability than fixed-wing aircraft, particularly fast jets. Helicopters can fly at treetop levels or even below the height of surrounding trees where there are clear areas (such as in river gullies), [ 1 ] flying under wires (such as electricity cables) rather ...
The British Auster WW2 reconnaissance aircraft had a placarded stall speed of 24 knots (44 km/h; 28 mph), [5] but that was merely the speed at which its control surfaces lost authority. As reported in many personal accounts by the pilots in their memoirs, the speed at which the aircraft would actually stall was 24 miles per hour (39 km/h).
Although the official record for fastest piston-engined aeroplane in level flight was held by a Grumman F8F Bearcat, the Rare Bear, with a speed of 850.23 km/h (528.31 mph), the unofficial record for fastest piston-engined aeroplane in level flight is held by a British Hawker Sea Fury at 880 km/h (547 mph).
British Airways Flight 216 reached a top speed of 809 mph Sunday and landed at London Heathrow 20 minutes early after departing its gate at 6:38 p.m., FlightAware data shows. Did these flights ...
The commercial Overture airliners will be able to carry 64 to 80 passengers at Mach 1.7, about twice the speed of today’s subsonic airliners, meaning a flight could cross the Atlantic in just ...
The fastest speed the XB-1 had reached prior to the January 28 flight was Mach 0.95, just below the supersonic threshold of Mach 1, which it hit during its last test flight on January 10.
Stall speed or minimum steady flight speed for which the aircraft is still controllable. [7] [8] [9] V S 0: Stall speed or minimum flight speed in landing configuration. [7] [8] [9] V S 1: Stall speed or minimum steady flight speed for which the aircraft is still controllable in a specific configuration. [7] [8] V S R: Reference stall speed. [7 ...
where a 0 is 1,225 km/h (661.45 kn) (the standard speed of sound at 15 °C), M is the Mach number, P is static pressure, and P 0 is standard sea level pressure (1013.25 hPa). Combining the above with the expression for Mach number gives EAS as a function of impact pressure and static pressure (valid for subsonic flow):
