In flight mechanics, the weight of an airplane refers to the force with which the aircraft is pulled toward the center of the Earth due to gravity. It is a fundamental parameter used to understand and analyze the aircraft’s performance and behavior during various phases of flight.
W = m * g
Where:
- W is the weight of the airplane (in newtons or pounds-force).
- m is the mass of the airplane (in kilograms or pounds).
- g is the acceleration due to gravity (approximately 9.81 m/s² or 32.2 ft/s²).
