In lots of wiki pages it says best flight ceiling for planes varies by up to 5000ft, optimal 2000ft, the most I can fly at without alot of effort, varies on campaign but around 700 max on Moscow, Tunisia, so it makes me think the measurement for height and speed is a different metric…
I also know that WT and EL are different gameplay wise, but if I climb to 700, what is that equivalent too?
I don’t have game open, I just want to know equivalent altitude and speed, ie 350TAS is 500mph?
This is false, TAS is not ground speed, TAS is your indicated airspeed corrected for atmospheric conditions and instrument error. Ground speed is literally ground speed.
