Definition#
Weight is the force of gravity acting on the total mass of the aircraft and its contents. In level flight, weight must be balanced by lift. Weight decreases during flight as fuel is consumed.
Why It Matters Operationally#
Weight determines required lift, stall speed, takeoff distance, climb rate, range, and landing distance. Exceeding weight limits (MTOW, max landing weight) is prohibited and may compromise structural integrity.
