Mach Number on Stall-Speed
I'm wondering if there's any generalized rules of thumb regarding the effect of mach number on stall-speed? Instinctively, I would assume supersonic aircraft would have the least effect, and subsonic aircraft the most.
With that said, what variations are there for an aircraft like an F-86 which was supersonic in a dive at low and high altitude? I was told the F-4 had a variation of around 15 knots from subsonic speed at low altitude and high subsonic-speed at around 35000 feet if I recall.
