in turn shall be significantly longer than the 1° mark. The marks and figures shall preferably be red or a light colour on a dark background.

(2) Additional linear range scales may be provided.

(3) Damping of the ROTI shall be provided with a time constant which may be varied during operation in the range zero to at least 10 seconds.

91. Accuracy—(1) The indicated rate of turn shall not deviate from the actual rate of turn of the ship by more than 0.5° per minute plus 5 per cent of the indicated rate of turn of the ship. These values include the influence of earth rate.

(2) Periodic rolling motion of the ship with an amplitude of ±5° and period of up to 25 seconds and periodic pitching motion with an amplitude of ±1° and period of up to 20 seconds shall not change the mean value of the indicated rate of turn by more than 0.5° per minute.

(3) The ROTI shall meet these accuracy requirements at all ship speeds up to 10 knots.

92. Operation—(1) The ROTI shall be ready for operation and comply with these standards within 4 minutes of being switched on.

(2) The design shall be such that whether operating or not the ROTI will not degrade the performance of any other equipment to which it is connected.

(3) The ROTI shall include a means of enabling the operator to verify that it is operating.
