The relationship between minimum control speed (VMC) and stall speed and the effect of density altitude on that relationship.
Bottom line
Where VS is encountered before VMC, the departure from controlled flight might be quite sudden, with strong yawing and rolling tendencies to the inverted orientation and a spin entry.
Key numbers
| Number | What it means |
|---|---|
| 3,000 feet AGL minimum throughout the maneuver | VMC demo floor |
| approximately 20 knots above VS when limiting rudder travel | Rudder-limit speed |
