How do you find maximum endurance?

For retractable gear, multiply by 1.8. In order to determine the approximate maximum-endurance airspeed, multiply your power-off stall speed by 1.2 for single-engine fixed gear airplanes and 1.3 for single- or multiengine retractable gear airplanes.

What is the maximum endurance?

Maximum endurance occurs when you have the greatest amount of flying time (T) for the least amount of fuel (F). Said another way, T/F is at a maximum. As can be seen below under Specific Endurance, the reciprocal of the fuel flow is your endurance and you get the best endurance at the low point of the curve.

How do you find the maximum endurance of an aircraft?

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.

Why is Max endurance at sea level?

Because the horsepower requirement for maximum endurance speed is much lower than the maximum rated output, the horsepower loss due to thinner air is not an issue until one is higher up. This is why “leaning” is required at higher altitudes. But “air density” is the correct answer.

What’s the difference between maximum endurance and range?

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 steady, level flight. Maximum range condition would occur where the ratio of speed to power required is greatest.

When does an airplane reach its maximum endurance?

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 steady, level flight. Maximum range condition would occur where the ratio of speed to power required is greatest.

Which is the fastest speed for maximum endurance?

The speed corresponding to the bottom of the power required curve is the speed for maximum endurance (Figure 1). Go to Top Maximum Range To maximize the range, we want to get the maximum distance for each pound of fuel burned. Starting with our basic relation or, splitting out the units Now if we divide both sides by velocity, we get

When to minimize fuel flow for maximum endurance?

In order to do this, we must minimize the fuel flow. Since the fuel flow is proportional to the power required, the fuel flow will be minimized at the point where the power required is a minimum. The speed corresponding to the bottom of the power required curve is the speed for maximum endurance (Figure 1). Go to Top Maximum Range
