What defines the maximum distance an aircraft can fly on a specific amount of fuel?

The maximum distance an aircraft can fly on a specific amount of fuel is defined by the concept of "max range." This term refers to the ability of an aircraft to travel the furthest distance possible using a set quantity of fuel. It takes into account various factors including aerodynamics, weight, engine performance, and cruising altitude, allowing for optimal fuel efficiency during flight.

Max range can be influenced by factors such as airspeed, altitude, and flying technique, making it a critical parameter in flight planning and operations, especially for long-distance flights. Knowing the max range helps pilots understand how to maximize the distance they can cover before needing to refuel, which is essential for mission planning and safety considerations.

Best glide speed and max endurance, while related to operational efficiency and time spent in the air, focus on different aspects of flight—gliding effectively without engine power and prolonging flight duration, respectively. Those factors do not directly address the maximum distance achievable with the available fuel.
