Any abnormality in the parameters of oil will lead to other operations related problems in the steering gear. 4. Check that Stand-by DG is on auto-start. In effect the autopilot 'learns' the vessel's handling characteristics in calm weather and then, when the weather deteriorate, can distinguish between those errors in heading due to the weather and those due to vessel's normal handling characteristics. This produces electrical impulses by operation of the steering control. Three state estimation algorithms are discussed and their performance in estimating the steering angle is tested under several scenarios including model uncertainty, measurement noise and sensor faults. The system waits 30-45 seconds to give the homeowner a chance to deactivate the system to prevent false alarms. The video signals for the various channels are then routed to a conventional video and audio distribution system on the aircraft which distributes . For non-hydraulic type.
