2. Range (aeronautics) - Wikipedia

   en.wikipedia.org/wiki/Range_(aeronautics)

   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. The maximum range condition is obtained at maximum lift/drag ratio (L/DMAX)

3. Fuel economy in aircraft - Wikipedia

   en.wikipedia.org/wiki/Fuel_economy_in_aircraft

   By increasing efficiency, a lower cruise-speed augments the range and reduces the environmental impact of aviation.According to a research project completed in 2024 and focusing on short to medium range passenger aircraft, design for subsonic instead of transonic speed (about 15% less speed) with turboprop instead of turbofan propulsion would save 21% of fuel compared to an aircraft of ...

   Design speed for maximum gust intensity. [7] [8] [9] V C: Design cruise, also known as the optimum cruise speed, is the most efficient speed in terms of distance, speed and fuel usage. [16] [17] [18] V cef: See V 1; generally used in documentation of military aircraft performance. Denotes "critical engine failure" speed as the speed during ...

6. Cruise (aeronautics) - Wikipedia

   en.wikipedia.org/wiki/Cruise_(aeronautics)

   [6] [7] [better source needed] The speed which covers the greatest distance for a given amount of fuel is known as the maximum range speed. This is the speed at which drag is minimised. For jet aircraft, "long-range cruise" speed (LRC) is defined as the speed which gives 99% of the maximum range, for a given weight.

7. Drag curve - Wikipedia

   en.wikipedia.org/wiki/Drag_curve

   The minimum power required, at a speed of 195 km/h (121 mph) is about 86 kW (115 hp); 135 kW (181 hp) is required for a maximum speed of 300 km/h (186 mph). Flight at the power minimum will provide maximum endurance ; the speed for greatest range is where the tangent to the power curve passes through the origin, about 240 km/h (150 mph).

8. Rolls-Royce ACCEL - Wikipedia

   en.wikipedia.org/wiki/Rolls-Royce_ACCEL

   It is designed to have the highest energy density for an aircraft, and should allow a 170 nmi (310 km) range. [3] The aircraft is derived from the carbon fibre Sharp Nemesis NXT racer, which has a cruising speed of 282 kn (522 km/h) with a 350 hp (261 kW) piston engine, but can reach 355 kn (657 km/h) with a highly tuned engine. The maximum ...

9. Speed and rate of climb - Wikipedia

   en.wikipedia.org/wiki/Rate_of_climb

   The Cessna 172 is a four-seat aircraft. At maximum weight it has a V Y of 75 kn (139 km/h) indicated airspeed [4] providing a rate of climb of 721 ft/min (3.66 m/s). Rate of climb at maximum power for a small aircraft is typically specified in its normal operating procedures but for large jet airliners it is usually mentioned in emergency ...
