Route Page 1/X
The route is entered and displayed in air traffic control format.
The first route page displays origin and destination data. Route segments are
displayed on subsequent route pages.
Individual portions of the route may be manually entered by the flight crew. A
pre–defined route may be loaded using the CO ROUTE line. CO ROUTE entries
must correspond to a company defined route in the navigation database.
The route x (1 or 2) may also be uplinked.
A route entered into RTE 2 allows the pilot to Activate, Predict and Erase a second
route. The Active Route can be copied "COPY" into the second route "RTE 2". All
flight planning capabilities, are available for the second route with the exception
of Lateral Offsets and Direct To processing. Entering a departure runway can be
done while in the air. The ERASE capability allows the crew to deactivate an
activated plan. This allows the crew to use the second route as a "what if"
predictor.
Messages that reference a route reflect the route to which they apply (i.e.,
PARTIAL ROUTE X LOADED).
1B401 - 1B785, 1B801 - 1B824, 1J590 - 1J594
The ACARS and FANS (as installed) functions include the second Route.
RTE 2 requires a separate set of Inactive Performance Data for "what if"
predictions. This is accomplished by adding an inactive state to the Perf Init page
when the Inactive Plan is activated. When an Inactive Plan becomes activated, the
ACT PERF INIT is demoted back to an INACT PERF INIT page. Demoting
means that the ACT will no longer be displayed in the title and ERASE for the
ACTIVATED plan will be displayed in 6L.
Perf Init Data can be entered (and completed) at any time. The completed Perf Init
data is not applied to any route until the route is ACTIVATED. Changes made to
Perf Init data after the RTE is activated will be removed when the ACTIVATED
route is ERASEd. If the ACTIVATED route is EXECd, the inactive Perf Init
becomes part of the Active Route.
