Continue adding waypoints to the new route until you have created
the complete route. Then press ENTER to save the route
Correction of routes
Deleting waypoints from the route list does not affect the listing of the
waypoints in the waypoint memory. Use the PORT or STBD push
buttons to move the pointer in the route list until you point at the
waypoint. Then press the DEL softkey. The waypoint will be removed
from the route list, and all other waypoints in the list will be shifted up
one location.
Inserting waypoints in a route list will add the new waypoint at the
pointer in the route list. Present waypoint and all waypoints below will
shift down one position in the list to make room for the new entry.
Replacing a waypoint in a list with a different waypoint name,
requires that you add the new point and delete the old point.
When you are finished correcting the route, press ENTER to save the
changed route list.
2.15 Navigating with the AP300DLX
The AP300DLX has the ability to provide automatic navigation in the
following different ways:
• To a temporary waypoint (TEMP-WP)
• To a stored waypoint
• Through a route of waypoints
• To a special man overboard waypoint (MOB)
Note ! When navigating with the AP300DLX, a valid POS source must be selected.
The AP300DLX will automatically be selected as NAV source when
operating in NAV mode (ref. page 56 and 58).
WARNING ! Loran C and Decca have inaccuracies introduced by changes in
the signals when they travel overland. The corrections included
in most Loran sets to account for variations in the Loran
transmitted signals are called ASF (Additional Secondary phase
Factor) corrections. It is recommended that you verify the
position accuracy between the Loran and your actual position,
and between the Loran and the GPS receiver(s) if you have more
than one position sensor on board.
