I had someone give me the following source:
It didn't really help me much though.
I see that it said that true airspeed is the speed of the plane relative to the atmosphere. However, if you pick a stationary point of space in the atmosphere, it would seem to be the same as airspeed relative to the ground because both the ground and the atmosphere are fixed points.
I'm really annoyed by this already and want to understand what "relative to the air" indicates and why the speed of the plane is not effected by either the wind speed (which I assumed was the air) or the stationary point in the atmosphere (which appears to be the same as relative to the ground).
