Proper procedures for maneuver entry and safe recovery.
Proper procedures for maneuver entry and safe recovery.
Bottom line
The moment the pilot first recognizes the uncontrollable yaw, or experiences any symptom associated with a stall, the pilot simultaneously retards the throttle for the operating engine to stop the yaw and lowers the pitch attitude to regain speed. A VMC demonstration that is allowed to degrade into a single-engine stall with high asymmetrical thrust may result in an unrecoverable loss of control and a fatal accident.
Key numbers
| Number | What it means |
|---|---|
| At least 3,000 feet AGL for the VMC demonstration | Min altitude |
| Approximately 10 knots above VSSE or VYSE, whichever is higher | Entry speed |
| 1 knot per second, no faster | Decel rate |
| Up to 5 degrees, as appropriate for the airplane make and model | Max bank |
| Approximately 20 knots above VS when limiting rudder travel | Rudder limit speed |
