systems that include a joystick controller.
Check the connections to, and operation
of the joystick.

EV-1 and ACU, or EV-2 and drive
interface unit.
Check all physical data connections
between these devices, as appropriate.
PILOT RESET NORMAL (UNEXPECTED
HARDWARE RESET)
• Autopilot resets due to an external
event (such as use of the sleep switch,
or faulty wiring causing the autopilot
components to power cycle).
Check all system wiring, especially
power-related wiring.

The EV-1 / EV-2 software has detected
a fault it cannot recover from, and has
reset the pilot.

/ EV-2 to reset and re-initialize.
