N1 LIMIT Page - Preflight
This section describes the preflight version of the N1 LIMIT page. See the FMC
Takeoff and Climb section for a description of the in–flight version of the N1
LIMIT page.
The N1 LIMIT page is used during preflight to manage takeoff and climb thrust.
Temperature data is entered, allowing the FMC to make N1 computations for
normal or reduced thrust takeoff. Fixed takeoff and climb thrust derates may be
selected.
1 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.
2 Outside Air Temperature (OAT)
Aspirated TAT displays the sensed OAT in small–size characters. Manual entry of
actual takeoff OAT is displayed in large–sized characters.
