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).
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 ...
One low-speed spin test of 50 rpm and one high-speed spin test of 2,573 rpm of the rotor blades to take a health check of the helicopter after it endured sandstorms and temperatures as low as −124 °F (−87 °C) during the Martian winter.

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 ...
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).
For example, a flight test project conducted by the National Research Council of Canada titled “Aerodynamic Low-Speed Buffet Boundary Characteristics of a High-Speed Business Jet” and presented at the 24th International Congress of the Aeronautical Sciences involved an intermediate capacity, high-speed business jet with highly swept wings ...
Maximum Endurance and Range versus airspeed. The maximum endurance condition would be obtained at the point of minimum power required since this would require the lowest fuel flow to keep the airplane in a steady, level flight. Maximum range condition would occur where the ratio of speed to power required is greatest.
