(U4 and on) It is possible for CLB2 thrust to be greater than the selected reduced
takeoff thrust. Therefore, the thrust levers may advance when the thrust limit
changes to CLB 2.
Preflight Status (PRE–FLT STATUS)
Selectively displayed to allow line selection of the appropriate preflight pages
whenever the required entries on those pages are incomplete.
POS INIT is displayed if a valid IRS position entry disagrees with the position
determined by any IRS in the ALIGN mode; otherwise blank.
PERF INIT is displayed if any required PERF INIT entries are not completed;
otherwise blank.
ROUTE is displayed if a route is not active; otherwise blank.
DEPARTURE is displayed if RTE page 1 displays prompts for RUNWAY and
VIA lines; otherwise blank.
Prior to completion of all required items, “PRE–FLT STATUS” appears above line
4. After completion of all required items, “PRE–FLT COMPLETE” appears.
INDEX
Push – displays the INIT/REF INDEX page.

V Speeds
Crew calculated V speeds may be entered and displayed for reference.
On airplanes with speed tapes, entered V1 and VR will automatically be
displayed.
Any change of performance information results in removal of all V speeds.

FLAPS
Automatically displays default takeoff setting of flaps 5.
May be used for manual entry of flap setting (1, 5, or 15).
Takeoff N1 (XXK N1)
Displays the FMC computed N1 for takeoff.
Crew entry not allowed.
Data line title displays full rated thrust or selected takeoff derate thrust. Typical line titles display as “22K N1” or “20K N1”. Data line title changes to “RED XXK N1” when an assumed temperature (SEL
TEMP) entry results in a reduced N1 value. If a SEL TEMP and a DERATE are both selected the data line title will change to “RED XXK N1,” and the effect on thrust will be additive. The Reference N1 bugs will still display full rated or selected takeoff derate thrust N1 values.
It is possible for CLB2 thrust to be greater than the selected reduced takeoff thrust. Therefore, the thrust levers may advance when the thrust limit changes to CLB 2.
Center of Gravity (CG)
Initial display is dashes.
After CG is entered and the gross weight calculated, the FMC calculates and
displays stabilizer takeoff trim setting.
Valid entries are 5 to 32, with resolution to a tenth of a percent.
TRIM
Displays the trim setting if gross weight is calculated and CG entered.
Display is blank unless CG is entered.
Preflight Status (PRE–FLT STATUS)
Selectively displayed to allow line selection of the appropriate preflight pages
whenever the required entries on those pages are incomplete.
POS INIT is displayed if a valid IRS position entry disagrees with the position
determined by any IRS in the ALIGN mode; otherwise blank.
PERF INIT is displayed if any required PERF INIT entries are not completed;
otherwise blank.
ROUTE is displayed if a route is not active; otherwise blank.
DEPARTURE is displayed if RTE page 1 displays prompts for RUNWAY and
VIA lines; otherwise blank.

Push – displays the INIT/REF INDEX page.
V Speeds
Crew calculated V speeds may be entered and displayed for reference.
Entered V1 and VR will automatically be displayed on the EFIS speed tape.
Any change of performance information results in removal of all V speeds.
Display Following Change of Performance Data (U7 and on)
REJECT
Displayed if takeoff speeds have been entered and gross weight or zero fuel weight
has been changed.
Selection causes the now small font takeoff speeds to disappear.
ACCEPT
Displayed if takeoff speeds have been entered and gross weight or zero fuel weight
has been changed.
Selection changes the small font takeoff speeds to large font.
