Weight

Weight is the force of gravity which acts vertically through the center of the airplane toward the center of the earth. The weight of the airplane is not a constant. It varies with the equipment installed, passengers, cargo, and fuel load. During the course of flight, the total weight of the airplane decreases as fuel is consumed. Additional weight reduction may also occur during some specialized flight activities, such as crop dusting, fire fighting, or sky diving flights.
