RAD NAV Calls up the RADIO NAV page. This page displays the radio navaids that are
tuned automatically or manually via the FMGEC.
FUEL PRED Calls up the fuel prediction page. When the engines start, this page displays
the predicted remaining fuel at the destination and the alternate, and fuel
management data.
SEC F-PLN Calls up the index page for the secondary flight plan. The flight crew can use
this page to call up the secondary flight plan and all the functions related to it
(copying, deleting, reviewing, activating, and the INIT and PERF pages).
MCDU MENU Calls up the MCDU MENU page, that displays the subsystems currently
addressed via the MCDU. The key next to the name of a subsystem enables the
flight crew to select that subsystem.
When the MCDU MENU annunciator lights up, the flight crew should press the
MCDU MENU key. The menu displays [REQ] next to the name of the subsystem
that requires attention.
AIRPORT Calls up the flight plan page that includes the next airport along the current flight

MCDU FUNCTION KEYS
The Multipurpose Control and Display Unit function keys enable the flight crew to quickly call up
MCDU pages.
The following summarizes the purpose of each key:
DIR Calls up the DIR TO page and enables the flight crew to proceed directly from the
present position to any waypoint entered manually or selected in the active flight
plan.
PROG Calls up the progress page corresponding to the phase of the active flight plan
that is in progress.
This page displays navigation information and active data such as the optimum
and maximum recommended cruise flight levels. It allows the flight crew to
update the FMGES position, and to get a bearing and distance to any location.
PERF Calls up the performance pages, which display the optimum speed or Mach
number for each phase. The flight crew can amend these pages. The first page
to be displayed is the one corresponding to the current flight phase (except for
preflight and done phases).
The flight crew can then use the appropriate 6L or 6R key to call up pages
corresponding to future flight phases.

INIT Calls up the flight plan initialization (INIT) A page, which also gives access to the
B page and IRS INIT page. The flight crew uses the INIT pages to initialize Flight
Management for the flight.
The flight crew primarily uses the INIT A page to insert the flight plan. The flight
crew uses the IRS INIT page to align the inertial reference system.
The flight crew uses the INIT B page to insert aircraft weight, Fuel on Board, CG,
and other fuel requirements. The FMGES uses this data to compute predictions
and fuel planning parameters.
The flight crew can access the INIT A page, for Flight Plan initialization, only in
the preflight phase. In flight, they can only modify the Alternate Flight Plan. IRS
INIT page is accessed via the "IRS INIT" prompt on the INIT A page. In the flight
phase, it is only accessible for information purposes.
The INIT B page (not accessible after engine start) is called up by pressing the
“← →” (NEXT PAGE) key.
DATA Calls up the data index page. This provides the flight crew access to various
reference pages that display aircraft position, aircraft status, runways, waypoints,
navaids, routes and data stored by the flight crew.
F-PLN Calls up the flight plan A and B pages, that contain a leg-by-leg description of the
active primary flight plan.
