Manually Entered Place–Bearing/Distance or
Place–Bearing/Place–Bearing Waypoint Names
Waypoints entered as a place–bearing/distance or place–bearing/place–bearing
are identified by the first three characters of the entry followed by a two–digit
sequence number. Examples:
• SEA330/10 becomes SEA01
• SEA330/OLM020 becomes SEA02.
Manually Entered Along–Track Waypoint Names
Along–track waypoints are a special case of place–bearing/distance waypoints
applied to the current route. When a waypoint is desired on the route where none
exists, the along–track waypoint feature creates the desired waypoint without
creating a route discontinuity.
Along–track waypoints are entered using the waypoint name (the place), followed
by a slash and minus sign, for points before the waypoint, or no sign for points
after the waypoint, followed by the mileage offset for the newly defined waypoint.
The route course takes the place of the bearing which is not entered. The created
waypoint is then inserted over the original waypoint. The distance offset must be
less than the distance between the originating waypoint and next (positive value)
or preceding (negative value) waypoint. Latitude and longitude waypoints cannot
be used to create along–track waypoints. Examples:
• VAMPS/25 is 25 miles after VAMPS on the present route, and is
displayed as VAM01
• ELN/–30 is 30 miles before ELN on the present route, and is displayed
as ELN01.
Greater Than 99 Numbered Waypoints
When the quantity of numbered waypoints exceeds 99 the identifier shall use the
first two characters of the entry followed by the smallest three-digit sequence
number beginning with 100. Examples:
• SEA104/74 becomes SE100
• SEA104/OLM064 becomes SE101.
Navigation Displays
The route is displayed on the navigation display in the map, map center, and plan
modes. The display color and format represent the following status:
• an inactive route is displayed as a cyan dashed line
• an activated but not yet executed route is displayed as a cyan dashed line
• the active route is displayed in magenta
• modifications to an active route are displayed as dashed white lines
• missed approach route is displayed as cyan dashed line until active
