The weight of an aircraft in unaccelerated flight is the gravitational force pulling the aircraft downward. It is countered by the lift generated by the wings, enabling the aircraft to maintain a constant altitude and trajectory without acceleration. The formula to calculate Weight is as follows:
Where:
- is the weight of the aircraft in N,
- is the lift generated by the wings in N,
- is the thrust produced by the engines in N,
- is the Thrust angle in radian.
