Use of stabilised electronic bearing line (EBL) So far, gyro input has been excluded from this paper. In pilotage, gyro compasses are frequently observed to be in error, lag during turns and sometime just wander. Perhaps new compass technology will increase the...
North up presentation The principles of this technique can be applied in north up mode provided the offseting of the EBL and VRM are relative to the vessel. However, with both the reference point and the index moving, this method retreats from the simplicity and...
Conclusion This method of conducting controlled turns is straight forward and easy to use. The planning is simple and results in turns being defined by their radius and a reference point’s distance from the turn centre. These two values allow for a quick and simple...
Apparent motion of targets on head up On head up display, the apparent movement of a fixed target is determined by the vessel’s own movement. The three degrees of freedom of a vessel’s horizontal movement are: longitudinal velocity – surge transverse velocity...
