ComNav 1101 Autopilot
Rudder Error
Occurring only in AUTOPILOT mode or NAV mode, this message will
be displayed if the Autopilot cannot detect any movement by the
rudder in response to a command to move.
1. Place the Autopilot in POWER STEER mode. Measure how long
it takes after pressing one of the DODGE buttons until the
digital rudder angle reading begins to change, particularly when
the last rudder movement was in the other direction.
a) If it takes longer than about 1 second for the rudder to
begin to move, check for air in the hydraulic steering
system, if so equipped.
b) Check for slack or worn parts in the steering system,
particularly if it is a mechanical steering system.
2. If the digital rudder angle reading does not change, but the
rudder is definitely moving, check for a broken Rudder Follower
Linkage, or a defective Rudder Follower.
