Correct answer is... 107 km/h. It is equal to 58 kn or 67 mph. It is higher value then stall speed of other aircrafts of a similar size. Average is about 18 km/h (10 kn or 11 mph).
The stall speed is the speed at which detachment of airstream going over the wing will occur. In practice, it deprives the Mooney M22 Mustang of the lift, the pilot, which leads to the free fall of the airplane. The pilot partly or fully loses the possibility to control the airplane.the stall speed depends on many factors. The pilot can positively influence the stall speed using flaps or slots (if installed). Then, the stall speed decreases. On the other hand, the pilot has to maintain much higher speed when turning. Then, the stall speed increases.
