5.4.1 All directional control systems shall normally
be operated from the craft's operating station.
5.4.2 If directional control systems can also
be operated from other positions, then two-way communication shall
be arranged between the operating station and these other positions.
5.4.3 Adequate indications shall be provided at
the operating station and these other positions to provide the person
controlling the craft with verification of the correct response of
the directional control device to this demand, and also to indicate
any abnormal responses or malfunction. The indications of steering
response or rudder angle indicator shall be independent of the system
for directional control. The logic of such feedback and indications
shall be consistent with the other alarms and indications so that
in an emergency operators are unlikely to be confused.
