If the vehicle isn't moving by the time the impeller reaches the stall speed, either it will start to move, or the engine RPM will no longer increase. In other words, stall speed is the engine RPM at which the torque converter transfers the power of the engine to the transmission. In the real world, the torque converter's stall speed roughly equates to the clutch engagement point on a manual transmission. Let's say you're driving your stick-shift car around town. Normally, you'd give the car a little gas and ease off the clutch pedal gently enough to get a smooth start.
When an airplane is flown at an angle that exceeds the critical angle of attack, the airplane will stall. In deliberate training stalls we decrease airspeed and avoid the abusive control inputs that cause unusual attitude stalls. Low speed is not the cause of the stall; the cause is the angle of attack.he normal stall is when the wing stalls. When the tail stalls it is called a tail-stall. The tail stalls are very abrupt and the nose pitches down near the vertical. This stall increases the effective AOA of the tail.
