Furuno RP-250 manual Bwr

4. WAYPOINTS, NAV LINE

Note: Waypoints are automatically switched when own ship is either 1/2 of the arrival alarm range or 0.5 nm from next waypoint, whichever figure is larger. For example, the arrival alarm range is 2 miles. Since 1/2 of the arrival alarm range is 1 mile and it is larger than 0.5 miles, the waypoint will be switched when your ship is 1 mile from a next waypoint.

12.Press the [NAV MENU] key to close the menu.

Note: To display the nav line by using the external data, IEC 61162-1 data sentence BWR, BWC, RMB, or WPL is required. The order of priority is BWR>BWC>RMB>WPL. In case of simultaneous input BWR has priority. To use BWR, BWC, RMB for waypoint sentences, set USED WPL# to NAV LINE in the NAV INFORMATION 3 menu. That is the normal usage. To use the WPL for destination waypoint, set USED WPL# to WPT in the NAV INFORMATION 3 menu. This should only be used when connected to a navigator which outputs only the WPL data sentence. The data sentence and displayed data are as follows:

BWR: Range and bearing to waypoint (great circle)

BWC: range and bearing to waypoint

RMB: Generic navigation data (range and bearing to waypoint, latitude and longitude position of waypoint, course, etc.

WPL: Latitude and longitude of waypoint
