GENERAL&PURPOSE

This purpose is achieved by a series of indications and alarms to alert first the OOW and, if he is not responding, then to alert the Master or another qualified OOW.
. ● Additionally, the BNWAS may provide the OOW with emergency for immediate assistance if required.
. ● The BNWAS should be operational whenever the ship’s heading or track control system is engaged, unless inhibited by the Master.
