For a given altitude, trim, and power, the airspeed is always the same no matter the wind. Wind only affects groundspeed.

Ground speed = true airspeed + wind component (where you're computing a vector based on wind direction to determine what amount of it is either tail wind (+) or headwind (-).

If acceleration is zero.

(Internet, therefore pedantry).
