Ground velocity refers to the speed and direction of an object relative to the ground. In the case of a plane, it is the speed and direction at which the plane is moving over the Earth's surface.
Airspeed is the speed of an object relative to the air, while ground velocity takes into account the movement of the air itself. This means that ground velocity may be affected by factors such as wind speed and direction, while airspeed is not.
Ground velocity can be measured using instruments such as GPS (Global Positioning System) or by using mathematical calculations based on the plane's airspeed, heading, and wind speed.
Knowing the plane's ground velocity is important for navigation and flight planning. It allows pilots to accurately determine their position, track their progress, and adjust their flight path if needed.
Yes, ground velocity can change during a flight due to factors such as wind speed and direction. Pilots must constantly monitor and adjust for these changes to ensure a safe and efficient flight.
