Route check

The route check feature checks the safety of a route (registered route or a go to point
route). The system searches the chart along the route to find any dangerous objects,
in accordance with the operator's search conditions. If any objects are found the sys-
tem alerts the user with a report. Route check does not alter the route in anyway
to make it safer.
