Controls and Displays
FMS.30.72
LSK 2R - Derated Takeoff Thrust 2, T/O2(Optional). If the Dual Derate option is
enabled, then this field will by default, display the second Fixed-Percentage
Derate takeoff thrust limit T/O2. Additionally, this field will display T/O1 when
T/O2 is selected to be the active takeoff thrust limit. If either ALT T/O, FLX
DERATE, or OVRD T/O is selected, then T/O1 and T/O2 are not displayed. If the
Dual Derate option is not enabled, then this field is blank.
LSK 3L - Maximum Continous Thrust (MCT). Always displays the Maximum
Continuous Thrust (MCT) limit.
LSK 3R - Alternate Thrust Rating, ALT (Optional). If the ALT Takeoff option is
enabled, then this field will display the inactive, alternate takeoff thrust limit
(ALT), a 3% derated takeoff thrust limit. Pressing LSK 3R displays “ALT T/O”
in 1L as the ACTIVE thrust limit, indicated by an arrow, and places “T/O” in 3R.
This field is blank if the ALT Takeoff option is not enabled or the FMS has
transitioned out of the takeoff flight phase.
LSK 4L - Maximum, Climb Thrust (CLB). Always displays the Maximum Climb
Thrust (CLB) limit.
LSK 4R - Takeoff Thrust Override, OVERRIDE (Optional). If the Takeoff
Override option is enabled, then this field will display “OVERRIDE [ ]” in 4R,
where the pilot can enter the override thrust limit value into the blank field
between the brackets. If an override thrust limit is entered, then 1L displays
“OVRD T/O”as the ACTIVE thrust limit, indicated by an arrow, with the entered
thrust limit to the right. This field is blank when OVRD T/O is the ACTIVE
takeoff thrust limit or the Takeoff Override option is not enabled. An OVRD T/O
entry can be cleared with the CLR key or by selecting any other available takeoff
thrust limit.
LSK 5L - Derated Climb Thrust 1, CLB1 (Optional). If the Single Derate option
is enabled, then this field will display the ARMED or ACTIVE/selected
fixed-percentage climb thrust limit, CLB1(by default). If the Dual Derate option
is enabled, then this field will display the active fixed-percentage derated climb
thrust, CLB1 (by default) or CLB2.
LSK 5R - Derated Climb thrust 2, CLB2 (Optional). If the Dual Derate option
enabled, then this field will display the unarmed or inactive fixed-percentage
derate climb thrust limit, CLB2 (by default) or CLB1 (if CLB2 is the ARMED or
ACTIVE thrust limit). If the Dual Derate option is not enabled, then this field will
be blank.
LSK 6L - Maximum Cruise Thrust (CRZ). Always displays the Maximum Cruise
Thrust (CRZ) limit.
LSK 6R - RETURN Prompt. Selection of this prompt returns to the previous FMS
page from where the THRUST LIMITS page was accessed (TAKEOFF, PERF,
or GO-AROUND).
