- If acceleration is continued or collective is decreased with stabilator trailing edge down, longitudinal control will be lost.
- Slew stabilator to 0' above 40 kias, full down below 40 kias.
- If stabilator is slewed to 0' and Auto Control Reset is pressed during acceleration, a pitch down nose attitude may occur.

- Pressing Auto Control Reset after a failure results in auto mode for one second.
- If a signal to one actuator is present, the stabilator could move 4' - 5'.
- Multiple attempts could result in an unsafe position.
