BDI display

The BDI display shows deviation from the bearing to waypoint and distance to waypoint. Cross track Error, Bearing to Waypoint, Distance to Waypoint, Time to Go, COG and SOG are also shown. Time to Go is calculated on the basis of distance to destination and velocity made good towards destination.

D4701_1

The line to the waypoint symbol is shown at an angle equal to the difference between the COG and the Bearing to Waypoint. The waypoint symbol is the symbol of the target waypoint as seen on the chart.

The range scale automatically scales for distance. The ranges shown are 4nm, 20nm, 40nm, 100nm, 200nm, 400nm, 1000nm, 2000nm, 4000nm. In each case the range scale has graduations at ¼, ½ and ¾ of the current scale.

The steering instruction is STEER STARBOARD if the waypoint line is 1° or more to port, STEER PORT if the waypoint line is 1° or more to starboard or ON COURSE if the waypoint line is dead ahead. If no GOTO or follow is in progress, the steering instruction is NO TARGET, no steering arrows are shown, but the rhumb line indicator is shown.

The graphical XTE indication will place arrows either side of the steering instruction and pointing towards it dependent on the difference between COG and bearing to Waypoint. The first arrow is shown when the difference reaches 5° and thereafter at 5° intervals.
