So at a certain altitude stall speed and mach buffet speed meet
|Quoting Rsbj (Reply 7):|
I believe stall speed increases with altitude because air has momentum
|Quoting Wingscrubber (Reply 9):
Rsbj, I understand your idea about air having momentum and causing the airflow to detach earlier, but remember its the aircraft which has the momentum, not the air Smile
The air being thinner, or rather the lower ambient pressure would be the main factor though...
|Quoting Jspitfire (Reply 2):
In smaller, slower aircraft, the aircraft's ceiling is determined by it's engine performance. On large aircraft, the ceiling is where Vmo and Vs meet.
