Climb thrust is automatically selected at the thrust reduction point on the
TAKEOFF REF page 2.
8
Reduced Climb (CLB–1 and CLB–2)
Push – selects the associated reduced thrust climb mode.
CLB–1 provides a climb limit reduced by 3% N1 (approximately 10% thrust).
CLB–2 provides a climb limit reduced by 6% N1 (approximately 20% thrust).
Deletion results in the selection of CLB thrust.
Manual selection of a climb thrust rating overrides the automatic selection.
Takeoff data uplink may automatically select a thrust derate.
9
TAKEOFF
Push – displays the TAKEOFF REF page.
1B801 - 1B806
10
Takeoff Bump Thrust (TO–B)
Push – selects takeoff bump thrust limit
Selection of TO–B automatically selects CLB thrust.
Data line title displays takeoff bump thrust. Typical line titles display as “26K
BUMP” or “28K BUMP.”
When takeoff bump thrust is selected, assumed temperature (SEL temperature)
thrust reduction is not available.
Takeoff data uplink may automatically select takeoff bump thrust.
Selecting Takeoff Thrust
Selecting the takeoff thrust displays <ACT> inboard of the selection. The FMC
automatically selects the highest climb thrust available (CLB, CLB-1, CLB-2)
which would not result in a thrust lever push, when the aircraft transitions from
takeoff to climb. <SEL> is displayed inboard of the selected climb N1 limit.
Takeoff Thrust Auto Selection
1B401, 1B402, 1B801 - 1B824
The Takeoff Thrust Auto Selection option provides a baseline thrust that is
automatically selected for specific airport locations and runways. The FMC can
auto–select an appropriate takeoff thrust rating based on airline policy and flight
crew entered airport/runway for the active flight plan.
