Wing Loading
The total weight of an aircraft divided by the area of its wings, affecting how fast it can fly and how maneuverable it is.
TECHNICAL DEFINITION
Wing loading is an aerodynamic parameter defined as an aircraft's total weight divided by its wing area, influencing its stall speed, maneuverability, climb rate, and overall flight performance characteristics.
BACKGROUND
The fuel economy in aircraft is the measure of the transport energy efficiency of aircraft. Fuel efficiency is increased with better aerodynamics and by reducing weight, and with improved engine brake-specific fuel consumption and propulsive efficiency or thrust-specific fuel consumption. Endurance and range can be maximized with the optimum airspeed, and economy is better at optimum altitudes, usually higher. An airline efficiency depends on its fleet fuel burn, seating density, air cargo and passenger load factor, while operational procedures like maintenance and routing can save fuel.

USAGE NOTE
High wing loading generally means faster flight but less maneuverability for an aircraft.
