11.1.1 All control and manoeuvring functions of
the craft should be exercised from the craft's control position.
11.1.2 An emergency device should be provided
independent of the main remote control systems to ensure that, in
the event of any one control system failure, it should be possible
to remove the propulsive thrust and bring the craft safely into the
displacement mode.
11.1.3 If provision is made for a machinery control
station outside the craft's control position, means of communication
should be provided between these positions; transfer of control from
one station to another should be effected only from the craft's control
position.
