What is the difference between Max range and max 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.
What is maximum endurance airspeed?
The maximum endurance of an aircraft (or the time aloft) refers to a flight condition that requires the minimum fuel power.
How do I max out my endurance?
To maximize the endurance, we want to maximize the amount of time that we can stay in the air. 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.
Why does range increase with altitude?
Air Density: Increasing altitude (decreasing air density) increases the range up to an optimum altitude, and then decreases again. Air density decreases the amount of power but as air density decreases, the resistance of the air decreases also, therefore that means less drag.

Why is the Mach number important to aerodynamics?
Because of the importance of this speed ratio, aerodynamicists have designated it with a special parameter called the Mach number in honor of Ernst Mach, a late 19th century physicist who studied gas dynamics. The Mach number M allows us to define flight regimes in which compressibility effects vary.
What is the maximum range of an aircraft?
The maximum range condition is obtained at maximum lift/drag ratio (L/DMAX). Increased aircraft weight increases the drag due to increase induced drag (greater lift required).
Which is the speed which gives the maximum range?
The speed which gives the maximum range for a given aircraft weight and altitude is called best range speed. Flying at higher speeds than the best range speed increases the drag and the fuel flow, and therefore reduces the range.
