Powered aircraft range is limited by the aviation fuel energy storage capacity (chemical or electrical) considering both weight and volume limits. [1] Unpowered aircraft range depends on factors such as cross-country speed and environmental conditions. The range can be seen as the cross-country ground speed multiplied by the maximum time in the ...
The maximum range condition is obtained at maximum lift/drag ratio (L/DMAX). The effect of altitude on the power required of a propeller-driven aircraft with same weight. Power required is inversely proportional to the endurance for a given fuel load. In aviation, endurance is the maximum length of time that an aircraft can spend in cruising ...
Takeoff safety speed. The speed at which the aircraft may safely climb with one engine inoperative. [7] [8] [9] V 2 min: Minimum takeoff safety speed. [7] [8] [9] V 3: Flap retraction speed. [8] [9] V 4: Steady initial climb speed. The all engines operating take-off climb speed used to the point where acceleration to flap retraction speed is ...
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. This results in a 3–5% increase in speed. [8] It is also a more stable speed than maximum range speed, so gives less autothrottle movement. [9]
As of 2020, more Learjet 35s have been sold than any other Learjet aircraft. [4] As a private jet the Learjet 35 was popular because of its good range (it can fly 2,056 miles nonstop), takeoff and landing performance (its Honeywell engines provide 3,500 pounds of thrust and can land on short runways at regional airports), fast cruise ...
An aircraft with drop tanks will have a greater radius of action than the same one without. In military aviation, the combat radius of an aircraft is often given with its mission profile (without in-air refueling). For example: The F-16 Fighting Falcon's combat radius is 550 km (340 mi) on a hi-lo-hi mission with six 450 kg (1,000 lb) bombs.
This is the speed which covers the greatest distance for a given amount of fuel. Maximum endurance (time in the air) is achieved at a lower speed, when drag is minimised. For jet aircraft, maximum endurance occurs when the lift-to-drag ratio is maximised. Maximum range occurs at a higher speed. This is because jet engines are thrust-producing ...
The Lockheed SR-71 Blackbird is the current record-holder for a crewed airbreathing jet aircraft. An air speed record is the highest airspeed attained by an aircraft of a particular class. The rules for all official aviation records are defined by Fédération Aéronautique Internationale (FAI), [1] which also ratifies any claims. Speed records ...
