3-12 FMS Subsystem
Departures Dropdown
When a departure is selected from the initial dropdown, a
sequence of dropdowns may be presented to allow the selection
of an enroute transition and a runway transition. The structure of
the departure and the presence of a selected runway will impact
whether a specific dropdown is presented.
The FMS processes enroute transitions first. If the departure has
more than one published enroute transition, the FMS will present
a dropdown showing those transitions and a transition must be
selected. If the departure has only one published enroute
transition, the FMS will automatically select that one and no
dropdown for enroute transitions will be presented. There are
departures that have no published enroute transitions. In those
cases, this entire step is skipped.
