“WTF is the difference between air speed and true air speed?”
It can be nothing, and it can be a huge amount. Depends on the relative wind and air density. I could be flying at an indicated air speed of 100kts, and not actually be moving forward, therefore, my true airspeed would be zero.
Ever seen or done a tailslide? Fun.
Oh I see, you were referring to the difference between true and indicated airspeed. Makes sense.
No, I have never done a tailslide. At least I dont think so (since I don’t know what a tailslide is). But one time I got myself into a major flat spin at only about 1000 ft, recovered with massive amounts of rudder, and then decided that civil avation was better off without me. I accepted the fact that some of us have the wrong stuff, and I never flew (solo) again.
