Final answer:
The True Airspeed (TAS) is affected by wind, while the Indicated Airspeed (IAS), Groundspeed (GS), and Calibrated Airspeed (CAS) are not.
Step-by-step explanation:
The A/S (airspeed) that is affected by wind is called the True Airspeed (TAS). TAS is the speed of an aircraft relative to the air mass in which it is flying. It takes into account the effect of wind on the airspeed and gives the actual speed of the aircraft through the air.
On the other hand, Indicated Airspeed (IAS), Groundspeed (GS), and Calibrated Airspeed (CAS) are not directly affected by wind. IAS is the speed read directly from the aircraft's airspeed indicator, GS is the speed of the aircraft relative to the ground, and CAS is the IAS corrected for installation and instrument errors.
