Best Lift Over Drag Ratio


Best Lift Over Drag Ratio (L/Dmax) is the maximum ratio of lift generated by an aircraft to the drag it experiences. It is the most efficient state of an aircraft in terms of producing lift with minimum drag. At this point, the aircraft can fly the furthest distance with the least amount of fuel. Pilots aim to maintain the aircraft at this ratio during cruise flight to maximize fuel efficiency. L/Dmax varies for different aircraft and is affected by factors such as weight, altitude, airspeed, and configuration. It is an important parameter in aircraft design and performance analysis.
