Raychart 425 Chartplotter Owner's Handbook Document # 81172_3 Date: March 2002 Raychart 425 Chartplotter iii Raychart 425 Chartplotter Owner's Handbook SAFETY NOTICES CAUTION: HIGH VOLTAGE The display unit contains high voltages. Adjustments require specialized service procedures and tools available only to qualified service technicians ­ there are no user serviceable parts or adjustments. The operator should never remove the display unit cover or attempt to service the equipment. CAUTION: NAVIGATIONAL AID This device is only an aid to navigation. [. . . ] The checkered pattern moves down the screen to simulate movement when SOG is greater than 2 knots. The steering instruction is STEER STARBOARD if the XTE is 0. 01nm or more to port, STEER PORT if the XTE is 0. 01nm or more to starboard or ON COURSE if the XTE is less than 0. 01 on either side. If no GOTO or follow is in progress, the steering instruction is NO TARGET. The graphical XTE indication places arrows either side of the steering instruction and pointing towards it, dependent on the value of XTE. Chapter 3: Operation 3-25 The first arrow is shown when the XTE reaches 0. 01nm, the second at. 05nm and subsequently at 0. 1nm intervals. 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 (Figure 3-41). D4701_1 Figure 3-41: BDI Display The line to the waypoint symbol is shown at an angle equal to the difference between the COG and the Bearing to Waypoint. The range scale automatically scales for distance. The ranges shown are 1nm, 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. 3-26 Raychart 425 Chartplotter 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. Waypoint Data The Waypoint Data display comprises text data occupying the whole screen (Figure 3-42). ROUTE ROUTE 01 WAYPOINT WPT 001 BRG 234° T RNG 12. 4 nm COG SOG XTE 230° T 6. 8 0. 5 Kts nm TIME 13:29 TTG ETA 01:03 14:32 12/12/99 12/12/99 STEER STARBOARD D4702_1 Figure 3-42: Waypoint Data Display If a route is not selected, the ROUTE field displays NO ROUTE. The WAYPOINT field shows the name of the waypoint. If the waypoint is part of a route then the title field includes the waypoint index in the route. If there is no target waypoint the text indicates NO WAYPOINT and all waypoint data is shown as dashes, one per character. If a route is being followed and the waypoint is not named, the text shows the waypoint number within the route (as displayed on screen). If a GOTO Cursor or Port is in progress, the text indicates GOTO CURSOR or GOTO `Port Name'. Any local time offset is set in the System Set Up menu, see Chapter 4. Chapter 3: Operation 3-27 The Time To Go (TTG) and Estimated Time of Arrival (ETA) data relate to the target waypoint (not the whole route) and are based on the Speed Over Ground (SOG) towards the target. If the VMG is negative, or data is not available, these fields are replaced by dashes, one per character. The steering instruction is STEER STARBOARD if the XTE is 0. 01nm or more to port, STEER PORT if the XTE is 0. 01nm or more to starboard or ON COURSE if XTE is less than 0. 01 on either side. 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 places arrows either side of the rhumb line indicator and pointing towards it, dependent on the value of XTE. The first arrow is shown when the XTE reaches 0. 01nm, the second at. 05nm and subsequently at 0. 1nm intervals. Note: The steering instruction and graphical XTE indication are repeated on all text-only displays. Navigation Data The Navigation Data display comprises text data occupying the whole screen (Figure 3-43): POSITION 50°45. 252 N 1°06. 000 W (c) COG 230° T SOG 6. 8 Kts WAYPOINT BRG 234° T RNG 2. 4 nm 001 GPS FIX OK TIME 14:32 12/12/99 STEER STARBOARD D4703_3 Figure 3-43: Navigation Data Display 3-28 Raychart 425 Chartplotter Textual data provides Position, SOG, COG, Bearing and Range to waypoint, Time, Fix status and the XTE indicator.
