Introduction
When first powered, the FMS is in the preflight phase. When completing a phase,
the FMS changes to the next phase in this order:
Preflight
During preflight, the flight crew enters the flight plan and load sheet data into the
CDU. Some data can be entered by datalink. The flight plan defines the route of
flight from the origin to the destination and initializes LNAV. Flight plan and load
sheet data provide performance data to initialize VNAV.
Required preflight data consists of:
Optional preflight data includes:
Preflight starts with the IDENT page. If the IDENT page is not displayed, it can
be selected with the IDENT prompt on the INIT/REF INDEX page. Visual
prompts help the flight crew select CDU preflight pages. Preflight pages can be
manually selected in any order.
After data on each preflight page is entered and checked, pushing the lower right
line select key selects the next preflight page. After selecting ACTIVATE on the
ROUTE page, the execute (EXEC) light illuminates. Pushing the EXEC key
activates the route.
The departure/arrival (DEP/ARR) page can be used to select a SID. Selection of
the SID may cause a route discontinuity. Resolution of the discontinuity and
execution of the modification should be accomplished on the ROUTE or LEGS
page.
