TO/GA position update inhibited if GPS UPDATE is ON.
Following TO/GA update, the runway identifier and any entered shift value are
highlighted in reverse video characters.

To remove a TO SHIFT entry, reselect RWY on the RTE page.
Runway Remaining (RWY REMAIN) YA686, YA687
Automatically displays the departure runway from the RTE page.
If a runway remaining distance is not entered and GPS UPDATE is OFF, the FMC
updates to the runway threshold when TO/GA is pushed.
If a runway remaining distance is entered and GPS UPDATE is OFF, the FMC
updates to the runway length remaining when the TO/GA switch is pushed.
TO/GA position update inhibited if GPS UPDATE is ON.
Following TO/GA update, the runway identifier and any entered shift value are
highlighted in reverse video characters.
To remove a RWY REMAIN entry, reselect RWY on RTE page.

Runway Wind (RW WIND)
Enter surface wind direction and speed. Entry is optional for preflight completion.
Runway Slope/Heading (RW SLOPE/HDG)
Enter runway slope.
Entry is optional for preflight completion.
Valid runway slope is U or + for up or D or – for down followed by slope in percent
gradient.
HDG displays runway heading for origin airport.
Runway Condition (RWY COND)
Active runway condition is highlighted:
.
DRY – Dry runway computations
.
WET – Wet runway computations
.
SK–R – Skid resistant runway computations Default condition is DRY. Runway condition can be selected by the flight crew or uplinked.

Selected Temperature (SEL)
Entry of an assumed temperature calculates a reduced thrust takeoff N1.
Entry can be made in degrees C or degrees F.
Maximum allowable entry is 70 degrees C (158 degrees F). The FMC, however,
will limit the N1 to 25% takeoff reduction.

Flight Management, Navigation -FMC Preflight 737 Flight Crew Operations Manual
Repeats data shown on the preflight version of the N1 LIMIT page.
Outside Air Temperature (OAT) YA721, YA722
Aspirated TAT displays the sensed OAT in small–size characters. Manual entry of
actual takeoff OAT is displayed in large–sized characters.
Sensed or manually entered OAT is used by the FMC to calculate the takeoff N1
limits.
Entry can be made in degrees C or degrees F.
Outside Air Temperature (OAT) YA613 - YA687, YA801 - YK104
Manual entry of actual takeoff OAT is used by the FMC to calculate the takeoff
N1 limits.
Entry can be made in degrees C or degrees F.
INDEX
Push – displays the INIT/REF INDEX page.
Takeoff N1 (XXK N1)
Displays the FMC computed N1 for takeoff.
Data line title displays full rated thrust or selected takeoff derate thrust. Typical
line titles display as “24K N1” or “22K N1.”
Data line title changes to RED XXK N1 when an assumed temperature (SEL
TEMP) entry results in a reduced N1 value. The Reference N1 bugs will still
display full rated or selected takeoff derate thrust N1 values.
Repeats the same information shown on TAKEOFF REF page 1 and the preflight
version of the N1 LIMIT page.
Thrust Reduction (THR REDUCTION) YA613 - YA687, YD651 - YD655
Altitude above origin airport elevation at which the autothrottle reduces from
takeoff N1 to climb N1.
The default value is determined by the airline and is stored in the model/engine
database. The default is displayed in small font.
Manual entries allowed on the ground. Entries must be between 800 to 9,999 feet
and are displayed in large font.
