Hello, when ATC on Expert Server instructs you to maintain 200 knots, it means airspeed or ground speed?
Because I had issues with this few times. I stalled and crashed on Expert Server, because the ATC instructed me to not exceed 180 knots, so I was flying 170 knots airspeed. But the ground speed was 210 knots. Then the ATC sent me: please, follow instructions or you will be ghosted. And again instructed not to exceed 180 knots. So then I thought they mean ground speed but it was too slow for me and I stalled and crashed.
So does it mean airspeed or ground speed?
Thanks a lot.
Merry Christmas by the way!
