The stall speed must be less than the landing speed which is 173mph (about 150 knots).
Also, as a rule of thumb, landing speed for an airplane should be less than about 225 knots since airplane tires are the limiting factor in landings and ideally one would land at the slowest speed possible without stalling.
Previous answer ...it's between 200mph and 350mph. (That's a pretty wide margin)
2193 mph
About 3 times the speed of sound. (3 mach)
What is SR71 auto insurance
The stall speed of an aircraft depends on its altitude, weight, configuration, and lateral and vertical acceleration. The stall speed for a 777 is dependent on these real-time factors.
I am not 100% sure but i think the stall speed of the F-15 eagle is around 500km\h I also saw a documentary that says the stall speed is 530km\h
The maximum speed of a SR71 is 2,200 mph at 80,000 ft.
The stall speed of an airplane is inversely proportional to the square root of the load factor. Therefore, with a load factor of 4, the stall speed would be 35 knots (70 knots / √4).
The stall speed is around 130knots for an F-15 C Eagle
SR71 Blackbird Model M-21: maximum speed: 2211miles/h Generally, the given answer for all models of the SR71 is: "In excess of Mach 3", or more than three times the speed of sound. see related links below for more info
164nm
450mph
In landing configuration (full flaps), the stall speed is 40 knots (indicated airspeed). With flaps up it is 48 knots.
