Plot Screen Use Examples

Station Keeping

There may be a time when you want to maintain your position at a given location in open

water. Some applications for this need may be:

Staying over a dive wreck.

•

Staying over a fishing hole.

•

Recovering an oceanographic survey point.

•

If you are placing and recovering crab pots along a course line, you can enter your course

in the RTE1 screen, then place the marker at each crab pot in turn.

You can also select WPT Pass Criterion: Distance to WPT in the CFG1 Navigation screen

and set the WPT Pass Distance: 0.00; or set the WPT Pass Criterion to Manual.

By doing this and putting the coordinate you want to maintain in the RTE1 screen, you

will always get the bearing and distance to the waypoint in the PLOT1 and NAV screens,

regardless of your angle of approach. Note for the plot example above, we turned off the

cross-track error lines, the active route, and track saving to keep the screen from getting

cluttered while drifting.

Grid Search

If you are attempting to search a given area, you can use the PLOT1 screen to view your

progress and help maintain your proper separation. You can also use the RTE1 screen’s

Insert New WPT feature in conjunction with the CFG1 Navigation, WPT Pass Criterion:

Distance to WPT (set the WPT Pass Distance: to the smallest acceptable value) to create

the search pattern you want to follow. In the RTE1 screen, highlight Insert New WPT and

press ENT to define the coordinates of the first waypoint. Then use the Insert New WPT

softkey to define subsequent range and bearing coordinates from your original position.

This technique allows you to quickly define your search pattern, control the pattern

separation, and view your progress along the way. The CDU will prompt you to turn at the

predetermined waypoints you defined. This allows you to pay more attention to the task at

hand, rather than having to keep a close eye on the GPS receiver.

The PLOT screen is not active until the antenna is detected.
