Takeoff Reference (TAKEOFF REF) YA721 - YA809, YC411, YC413
Push – Toggles altimeter reference between QFE and QNH.
Default is QNH.
Resets to QNH at flight complete.
Reflects LANDING REF selection on APPROACH REF page.
Active altimeter reference is highlighted.
During preflight with QFE selected, the PFD altitude indications show zero feet
at the departure runway threshold. The PFD altitude indication background colors
change to green.
If QFE is the current altimeter reference, and the EFIS control panel STD switch
is pushed, The takeoff reference automatically toggles to QNH.
Selected Climb Rating YA613 - YA687, YD651 - YD655
Displays the climb rating that will be set at the THR REDUCTION altitude, as selected on the preflight version of the N1 LIMIT page.

Menu Page YA686 - YK104
The menu page is selected with the MENU key or is automatically displayed when the currently active subsystem fails or on initial power up if the FMC system is not detected.
The menu page displays subsystems (ACARS, DFDAU, etc.) that require control/display functions through the MCDU and provides a means to temporarily access to these subsystems. The active system is indicated by <ACT> displayed next to the system title. A subsystem that requires use of the CDU displays a request message <REQ> next to the subsystem title. The FMC system or a requesting subsystem is accessed by using the line select key next to the title. The FMC can be reselected by selecting the FMC prompt on the MENU page or selecting any mode key (INIT/REF, RTE, etc.). A subsystem can be temporarily placed on hold <HLD> by selecting the subsystem XXXXXX HOLD> line select key returning the CDU display to the currently active FMC page (XXXXXX represents the system name). While the subsystem is on hold the MCDU CALL light is illuminated. To reselect the subsystem on hold, push the subsystem line select key again. When a subsystem is placed on hold a XXXXXX LOGOFF prompt appears to allow for release of the subsystem being held. No more than one subsystem can be selected at a time. If an attempt is made to select more than one subsystem, a FIRST LOGOFF XXXXXX prompt is displayed as a reminder to logoff the currently active subsystem.

Introduction
The FMC takeoff phase begins with the selection of takeoff/go–around (TO/GA). Preparation for this phase begins in the preflight phase and includes entry of the TAKEOFF REF page data.
The takeoff phase automatically changes to the climb phase when climb thrust is selected. The climb phase continues to the top of climb point, where the cruise phase begins.
During these phases, the following pages are normally used:
.
TAKEOFF REF page – to make last minute changes to the departure
runway
.
DEPARTURES page – to make last minute changes to the SID
.
CLIMB page – to modify climb parameters and monitor airplane climb
