True airspeed (TAS) refers to the actual speed of an aircraft relative to the surrounding air, excluding the influence of wind. During takeoff, while the aircraft's ground speed can be affected by wind conditions—such as increasing with tailwinds or decreasing with headwinds—true airspeed itself is independent of these factors. Therefore, true airspeed does not change regardless of whether there is a headwind, tailwind, or calm wind conditions during takeoff.

This relationship is essential for pilots to understand, as it helps ensure they are aware of their aircraft's performance and the atmospheric conditions affecting it. While ground speed will vary due to wind, true airspeed provides a consistent measure of the aircraft's speed through the air, which is critical for aerodynamic performance.
