The maximum range of an airplane refers to the max distance it can fly for a given fuel supply. This measurement is crucial for pilots and airlines as it determines how far an aircraft can travel on a full tank of fuel under specific conditions. Factors influencing maximum range include the aircraft's aerodynamic efficiency, weight, engine performance, and environmental conditions such as wind. Understanding maximum range enables pilots to plan fuel needs, flight paths, and operational limits effectively.

The other options do not accurately capture the concept of maximum range. Maximum duration airborne relates to how long an aircraft can stay in the air, which is influenced by fuel consumption rates but not a direct measure of distance. The highest altitude speaks to the performance capabilities during flight but does not provide insight into travel distance. Maximum speed refers to the aircraft's ability to move through the air but again does not correlate with how far it can travel given a specific amount of fuel. Thus, maximum range is distinct and specific to distance traveled per fuel load.
