Version 2.0 79Man Over Board Operator’s Manualapproach. Note for the plot example above, we turned off the cross-track error lines, the active route, and track saving to keep the screenfrom getting cluttered while drifting.Grid SearchIf you are attempting to search a given area, you can use the PLOT2screen to define a known coordinate in your search pattern, then useboth the PLOT1 and PLOT2 screens to view your progress and helpmaintain your proper separation. You can also use the RTE1 screen’sInsert New WPT feature in conjunction with the CFG1 Navigation,WPT Pass Criterion: Distance to WPT (set the WPT Pass Distance: tothe smallest acceptable value) to create the search pattern you want tofollow. In the RTE1 screen, press Insert New WPT to define the coor-dinates of the first waypoint. Then use the Insert New WPT softkey todefine subsequent range and bearing coordinates from your originalposition. This technique allows you to quickly define your searchpattern, control the pattern separation, and view your progress alongthe way. The CDU will prompt you to turn at the predeterminedwaypoints you defined. This allows you to pay more attention to thetask at hand, rather than having to keep a close eye on the GPS re-ceiver.Man Over BoardThe Man Over Board function key is located at the bottom right handcorner of the CDU. When depressed for a few seconds, it activates anumber of automatic functions described below. You can also active itby pressing E and selecting the Activate MOB softkey.Most obviously, it brings up an MOB1 (Plot) screen. This is an auto-matic scaling screen. The screen centers on half the distance betweenyour present position and the MOB position. In addition, the MOBposition is displayed in the upper left corner, so that you can quicklyread the coordinates to others who may be available to render assis-tance. This plot screen also provides the vital bearing and distanceback to the MOB position, as well as your present course over ground.
