Thrust Force (): This represents the force generated by the aircraft’s engines during the climb phase. It is the force that propels the aircraft forward and upward, overcoming various resistance forces, including aerodynamic drag and the component of gravitational force that opposes the climb.
- is the thrust force during the climb phase.
- is the aerodynamic drag force, which opposes the aircraft’s motion and varies with airspeed.
- is the weight of the aircraft, which is the force acting due to gravity and is equal to the mass of the aircraft multiplied by the acceleration due to gravity.
- is the flight path angle, which is the angle between the aircraft’s flight path and the horizontal plane.
