The power required at the beginning of a flight refers to the amount of power that the aircraft’s engines or propulsion system must produce to overcome the aerodynamic drag and other resistive forces during takeoff and initial climb.
Power required in the beginning of the flight =T*V/1000
- T: Thrust. It is the force generated by the aircraft’s engines or propulsion system to overcome aerodynamic drag and other resistive forces and propel the aircraft forward.
- V: True Airspeed (TAS). It is the actual speed of the aircraft relative to the surrounding air.
- 1000: The division by 1000 is used to convert the final result into kilowatts (kW) or another unit of power.
