RTE LEGS Page Modifications
When modifications are made to the RTE LEGS page, several automatic prompt
or identifying features assist in managing and executing the modifications, such
as:
• ERASE
• INTC CRS.
Adding Waypoints
A waypoint can be added to the route whenever necessary.
The new waypoint must first be placed into the CDU scratchpad. Existing
waypoints can be copied from a RTE LEGS page into the scratchpad by pushing
the line select key adjacent to the desired waypoint.
The new waypoint is then inserted into the route at the desired sequence point by
pushing the line select key adjacent to the desired location for the new waypoint.
Using the NEXT PAGE/PREV PAGE function keys to select the desired location
does not alter the CDU scratchpad. The new entry automatically links to the
preceding waypoint via a direct route. Placing the new waypoint into the active
waypoint line is a special case and is discussed under Intercept Course in this
section.
All new waypoints, except along track waypoints, cause a route discontinuity
between the new waypoint and the following waypoint.
Note:
If the FMC NAV database contains a HOLD pattern at the FAF, executing
a database approach with a procedure turn and then executing a HOLD at
the same FAF, using any inbound course, may cause a discontinuity
between the FAF and the procedure turn. If the discontinuity is removed,
LNAV guidance is available to fly the approach from the published holding
pattern. LNAV guidance is not available to fly the published procedure
turn.
