The two digit sequence numbers reserved for RTE1 are 01 through 49. The two
digit sequence numbers reserved for RTE2 are 51 through 99.
Manually Entered Airway Crossing Waypoints
Airway crossing fixes are entered as a five character waypoint name or by entering
consecutive airways on the ROUTE page. In the latter case, the display is an X
followed by the second airway name. Example: entering J70 on the VIA line of
the ROUTE page causes box prompts to display opposite on the same line.
Leaving the box prompts empty and entering J52 on the next VIA line, directly
below J70, causes the FMC to calculate the intersection of the two airways and
replace the boxes with the waypoint identifier, XJ52.
Manually Entered Latitude or Longitude Reporting Point Waypoints
Latitude or longitude reporting waypoints are entered as the full latitude or
longitude followed by a dash, then the increment chosen for the following
multiple waypoints. Example:
• W060–10 adds waypoints starting at W060 in ten degree increments from
that point to the destination
• the entry must be made on a LEGS page on any line before the first
reporting point
• usually, this entry is made on the active waypoint line and proper
sequencing is performed by the FMC
Manually Entered Along–Track Waypoints
Along–track waypoints are created on the active route and do not cause route
discontinuities when they are created.
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 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 displays as
VA M 0 1
• ELN/-30 is 30 miles before ELN on the present route and displays as
ELN01
