Displays the takeoff runway from the active RTE page if previously selected.
Runway entry does not change runway entered on RTE or DEPARTURES page.
Flight crew may enter or uplink runway and intersection data.
Valid entry of a runway intersection is an alphanumeric up to three characters,
preceded by a slash (/).
Valid position entry is a one or two numeric in the range 0-99. It must be followed
by two zeros and preceded by a slash (preceding the entry with a “-”means a
longer takeoff distance is available; for example, -0300 is 300 feet before the
runway threshold).
Entry of a value after takeoff speeds are selected deletes V speeds and displays the
CDU help window message TAKEOFF SPEEDS DELETED.
RWY/POS update inhibited when GPS is primary FMC navigation source.
Push – transmits a company datalink request for takeoff data.
Flight crew can enter RWY, intersection or position shift, CG, TOGW, or OAT to
qualify the request.
Push – displays the INIT/REF INDEX page.
Dashes display when:
• required information not entered
• IRS not aligned.
EFB calculated speeds display in small font. The takeoff data comes from the EFB
performance page and is sent over as an uplink to the FMC after the pilot initiates
SEND TO FMC on the EFB.
Flight crew entered or selected speeds display in large font and replace speeds
calculated by the EFB or uplinked. The following applies to manually entered or
accepted uplinked speeds:
• V1 speeds less than V1MIN are indicated by display of “MIN V1” in the
header line and the value of V1MIN in the data line.
• VR speeds less than V1MIN or VRMIN are indicated by display of
“MIN” in the header line and the greater value of V1MIN or VRMIN in
the data line.
• V2 speeds less than V2MIN or V2MINA are indicated by display of
“MIN” in the header line and the greater value of V2MIN or V2MINA in
the data line.

Push –
• selects V1, VR, and V2 to be sent to using systems, or
• crew entered V speeds replace EFB calculated or uplinked speeds
• display changes to large font; REF and caret no longer display.
If performance data changes:
• existing speeds are replaced with dashes
• V speeds are removed from the PFD
• PFD speed tape message NO V SPD displays
• CDU help window message TAKEOFF SPEEDS DELETED displays.
GR WT displays airplane gross weight from the PERF INIT page.
TOGW – entry of a TOGW followed by selection of the <REQUEST prompt
transmits a request for an uplink of new takeoff data based on the entered TOGW.
Valid entry is any weight within the allowable airplane takeoff gross weight range.
Entry of a TOGW after V speeds have been validated causes the V speeds to be
deleted and displays the CDU help window message TAKEOFF SPEEDS
DELETED.
A takeoff uplink displays the uplinked TOGW and associated V speeds.
Push – displays the THRUST LIM page.
Push – rejects the takeoff data uplink and returns the REQUEST prompt.
Push – accepts the uplink takeoff data; all pending uplink values are treated as if
entered by the flight crew.
