The velocity of the aircraft with respect to the ground, Vground, is its speed and direction relative to the Earth’s surface. It accounts for both the aircraft’s airspeed and the wind’s velocity. This velocity is essential for navigation, flight planning, and air traffic control. It determines the aircraft’s ground track and ground speed. Passengers experience this velocity as the sensation of movement during flight. The Formula to calculate Vground as follows:
Where:
- Vaircraft is the Aircraft velocity in m/s
- Vwind is the Wind velocity in m/s,
