In aviation, endurance is the maximum length of time that an aircraft can spend in cruising flight. in another word it is also the amount of an aircraft can stay on air with one load fuel. Endurance is different from range, which is a measure of distance flown.
What is the difference between the range and the endurance of an aircraft?
Endurance is the measure of how long any aerial vehicle can stay aloft, it is a measure of time (hours, minutes, seconds). Range is how far an aerial vehicle can get on a load of fuel, it is a measure of distance (miles, kilometers, yards and meters). … However, at such a low speed its range is small.
How is aircraft endurance calculated?
Let us calculate the expression for endurance of a jet aircraft. For steady, level flight, TA = TR, minimum weight of fuel per unit distance cor- responds to a minimum TA/V . Kindly note that, since TA = TR, hence range of aircraft (with jet engine) will be maximum if N(fuel)/m is minimum or TR/V is minimum.
What is best endurance speed?
The speed which gives the minimum drag for a given aircraft weight and altitude is called best endurance speed. Flying at higher speeds then the best endurance speed increases the drag and the fuel flow, and therefore reduces the endurance.
What is the longest a plane can stay in the air?
The longest nonstop commercial flight in the world is scheduled at 17 hours and 50 minutes. This route from Los Angeles to Singapore serviced by United Airlines isn’t the longest by distance, but it has the longest duration due to commonly strong headwinds.
How do you calculate endurance?
- When the tensile strength is less than 200 kpsi (1400 MPa), the endurance strength = 0.5*tensile strength.
- When the tensile strength is greater than 200 kpsi (1400 MPa), the endurance strength = 100 kpsi (700 MPa)

How does temperature affect aircraft performance?
High air temperatures affect the physics of how aircraft fly, meaning aircraft takeoff performance can be impaired on hot days. The amount of lift that an airplane wing generates is affected by the density of the air. … The lower the air density, the faster an airplane must travel to produce enough lift to take off.
How do you find the maximum range of airspeed?
Multiply your power-off stall speed by 1.5 to determine maximum-range airspeed. For retractable gear, multiply by 1.8.
What is range of an aircraft?
The range can be seen as the cross-country ground speed multiplied by the maximum time in the air. The fuel time limit for powered aircraft is fixed by the fuel load and rate of consumption. When all fuel is consumed, the engines stop and the aircraft will lose its propulsion.
What is maximum range airspeed?
Therefore, the maximum range airspeed occurs where a line from the origin is tangent to the power required curve. … This also corresponds to the minimum point on the thrust required curve (drag polar).
What is maximum cruise speed?
The typical cruising airspeed for a long-distance commercial passenger aircraft is approximately 880–926 km/h (475–500 kn; 547–575 mph).
What is long range cruise speed?
Long-Range Cruise (LRC) speed is the traditional cruise speed. It has been historically defined as the speed above Maximum-Range Cruise (MRC) speed with a 1 percent decrease in fuel mileage, but a 3-5% gain in cruise velocity, as illustrated below.
How can aircraft improve performance?
5 Ways To Improve Your Aircraft’s Performance
- 1) Reduce the weight. Reducing unnecessary weight can help in a lot of ways. …
- 2) Move the center of gravity aft. Having an aft center of gravity will reduce your tail down force (but remember, you need to stay within CG limits). …
- 3) Lean the mixture. …
- 4) Choose the right altitude. …
- 5) Incorporate drag reducing devices.

Why do planes do not fly over the Pacific?
The primary reason airplanes don’t fly over the Pacific Ocean is because curved routes are shorter than straight routes. Flat maps are somewhat confusing because the Earth itself isn’t flat. Rather, it’s spherical. As a result, straight routes don’t offer the shortest distance between two locations.
What is the shortest flight in the world?
The record holder for the world’s shortest commercial flight is scheduled for just 90 seconds. In good conditions, Loganair’s 1.7-mile jaunt between the Scottish islands of Westray (population: 640) and Papa Westray (population: 72) in the Orkneys, off the north coast of the mainland, can take under a minute.
Do planes stop in the air?
No a plane doesn’t stop in midair, planes need to keep moving forward to remain in the air (unless they are VTOL capable). What it can do is simply turn around or go over/under the obstruction. VTOL means vertical takeoff and landing. It essentially means they can hover in place like a helicopter.
