Route 2 Feature
YW273, YW274
(SB Changes YK981 - YQ456)
RTE 2 adds the capability of a second route to the existing FMC software and adds
new prompts to the RTE and RTE LEGS pages that allows access to the second
route. The DEP/ARR Index page is updated to access the Departures and Arrivals
for the second route.
RTE 2 adds the capability to Activate, Predict and Erase a second route. The
Active Route can also be copied "COPY" into the second route. All flight planning
capabilities, are available for the second route with the exception of Lateral
Offsets and Direct To processing. The RTE 2 Feature also adds the capability of
entering a departure runway 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, have been update to reflect the route to which
they apply (i.e., PARTIAL ROUTE LOADED has been changed to PARTIAL
ROUTE X LOADED).
YW273, YW274
The ACARS functions are included with the second Route.
YK981 - YQ456
The ACARS and FANS functions are include with the second Route.
Adding the second Route 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.
