The route action field also features a copy function that permits you to copy any
route to another open storage route. The copy function can be used to save the con-
tents of the active route (route 0) to an open storage route.
To copy a route:
1. Press
R
and use
O
to display the route catalog page.
2. Use K to display the route to which you would like to copy to. The route must be empty.
3. Press C twice and rotate K to select ‘copy?’. Press E .
4. Use K to enter the route you would like to copy. The departure/arrival identifiers will be
displayed for your reference. Press
E
to copy the route.
The CPA function calculates the closest distance that a route will pass to a refer-
ence waypoint, and helps when creating new route waypoints referenced to a NAVAID.
To calculate the closest point of approach (CPA) from the route catalog page:
1. Use
K
to display the route you would like to use for the CPA function. The route must con-
sist of at least two waypoints, and the reference facility must fall between the waypoints of
a route leg.
2. Press
C
twice and rotate
K
to select ‘cpa?’. Press
E
.
3. Use
K
and
O
to enter the identifier of the reference waypoint.
4. Press
E
. The bearing and distance of the closest point on the route will be displayed.
5. Press
E
to add the cpa waypoint to the route, or
\
to finish. If you do add the cpa
waypoint to the route, it will be named based on the reference waypoint plus a number (0-
9) added to the end (e.g., KMCI3 for KMCI). If the waypoint does not fall between waypoints
on the route, the reference waypoint does not exist or a unique name cannot be assigned to
the CPA waypoint, you’ll be informed with the ‘Invald CPA wpt ____’ message.
