Ground speed is the horizontal speed of an aircraft or other object relative to the Earth’s surface. It is the actual speed at which the object is moving over the ground. The ground speed is affected by both the true airspeed (the speed of the aircraft through the air) and the wind speed and direction.

Equivalent Airspeed (EAS) in flight mechanics refers to the calibrated airspeed corrected for compressibility effects. It represents the airspeed at sea level that would result in the same dynamic pressure as the true airspeed at a given altitude. EAS is a valuable parameter for aircraft performance calculations and flight testing, allowing for a more accurate
