The Coefficient of Lift for Max Glide Endurance is a parameter that signifies the lift efficiency required for achieving the longest possible duration of unpowered flight. It represents the ratio of the lift force generated by the aircraft’s wings to the dynamic pressure of the surrounding air and the wing’s area. In the context of maximizing glide endurance, this coefficient indicates the optimal lift-to-drag ratio attained by adjusting the aircraft’s angle of attack. By operating at the angle of attack corresponding to the maximum lift coefficient, aircraft can sustain flight for extended periods without engine power, crucial for applications like gliders or endurance UAVs. The formula to calculate Coefficient of lift for Max Glide Endurance as follows:
Where:
- CL is the Coefficient of Lift,
- CD0 is the Zero Lift Drag Coefficient,
- K is the  Constant, (K=1/(pi*e*AR)).
