Flight crew entry or uplink.
Entry of 5 when FLAPS 5 is the climb thrust reduction point displays the CDU
help window message INVALID ENTRY.
Entry of a value after takeoff speeds are selected removes the speeds and displays
the CDU help window message TAKEOFF SPEEDS DELETED.
Displays takeoff thrust selected on THRUST LIM page, or flight crew or uplink
entered assumed temperature for takeoff thrust derate calculations.
Entry is only allowed when the airplane is on the ground and dash prompts or large
font temperature data is displayed.
Valid entries are 0 to 99 degrees C or 32 to 210 degrees F. Fahrenheit entries must
be appended with an “F”.
Entry of a value after takeoff speeds are selected removes the speeds and displays
the CDU help window message TAKEOFF SPEEDS DELETED.
Valid entry is CG within the valid range.
After CG entered, the FMC:
• calculates and displays the stabilizer takeoff setting to the right of the CG
entry (trim display is in 0.25 unit increments)
• updates the takeoff green band displayed on stabilizer position indicator.
Displays the selected takeoff runway, and TO/GA push distance from the runway
