11.40.33
Data line title displays full rated thrust. Typical line titles display as “24K” or
“26K.”
Selection of a new rating after V speeds are selected on the TAKEOFF REF page
causes the V speeds to display in small font, and the NO VSPD flag to show on
the airspeed indication.
4
Takeoff Derates (TO–1 and TO–2)
Push – selects the associated takeoff thrust limit.
Takeoff data uplink may automatically select a thrust derate.
The data line title displays the associated Percentage Takeoff Derates for reduced
thrust ratings.
The default percent derates are set at 10% for TO-1 and 20% for TO-2.
Normally, selecting TO–1 automatically arms CLB–1 and selecting TO–2
automatically arms CLB–2.
Note:
If a reduced thrust takeoff has been specified, then either CLB–1 or CLB–2
may be automatically specified if required to avoid a climb N1 value
greater than the specified reduced thrust takeoff N1.
Selection of a new rating after V speeds are selected on the TAKEOFF REF page
causes the V speeds to display in small font, and the NO VSPD flag to show on
the airspeed indication.
5
PERF INIT
Push – displays the PERF INIT page.
6
Takeoff 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 “TO N1” or “TO-1 N1” or “TO-2 N1”.
Data line title changes to RED TO 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 TO-X N1,” and the effect on thrust
will be additive.
1B801 - 1B806
Data line title changes to TO-B N1 when takeoff bump (as installed) thrust is
selected.
7
Climb (CLB)
Push – selects full rated climb thrust limit.
