Range (aeronautics)
Videos
The maximal total range is the maximum distance an aircraft can fly between takeoff and landing. Powered aircraft range is limited by the aviation fuel energy storage capacity considering both weight
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 a steady, level flight. Maximum range condition would occur where the ratio of speed to power required is greatest. The maximum range condition is obtained at maximum lift/drag ratio (L/Dmax)
Lift-to-drag ratio
Videos
In aerodynamics, the lift-to-drag ratio is the lift generated by an aerodynamic body such as an aerofoil or aircraft, divided by the aerodynamic drag caused by moving through air. It describes the aer

…The corresponding fuel weight flow rates can be computed now: F = c p P b r Thrust power is the speed multiplied by the drag, is obtained from the lift-to-drag ratio: P a = V C D C L W g ; here Wg is the weight (force in newtons, if W is the mass in kilograms); g is standard gravity (its exact value varies, but it…
Drag vs Speed. L/DMAX occurs at minimum Total Drag (e.g. Parasite plus Induced)
