Recognize conditions that lead to a spin for future avoidance.
Bottom line
In order to spin any airplane, a stalled condition needs to exist. At the stall, the presence or introduction of a yawing moment can initiate spin entry. In a multiengine airplane, the yawing moment may be generated by rudder input or asymmetrical thrust.
Key numbers
| Number | What it means |
|---|---|
| no lower than 3,000 feet AGL for multiengine slow flight, or higher if recommended by the manufacturer | Slow flight floor |
| recovery no lower than 3,000 feet AGL for multiengine stall practice, or higher if recommended by the AFM/POH | Stall practice floor |
| never introduce an engine failure below VSSE; if no VSSE is published, use VYSE | Engine failure floor |
