AUTO THRUST LIMITS Page
AUTO THRUST LIMITS Page During Preflight/Takeoff
The THRUST LIMITS page, during preflight or takeoff, is shown above in AUTO
mode with the Dual Derate option enabled.
LSK 1L - T/O Thrust. Displays the available or ACTIVE/selected maximum
takeoff thrust limit (T/O, ALT T/O, or OVRD T/O) with corresponding N1 limit.
Selection will result in the making the thrust limit the ACTIVE thrust limit and
being displayed in large font.
Line 1C - TAT (Total Air Temperature) - TAT is displayed in small font.
LSK 1R - Flexible Derated Takeoff Thrust (FLEX). Entry field for the
pilot-enterable temperature for computing a flexible derated takeoff thrust limit.
Entering a flex temperature and pressing LSK 1R activates the Flex Derate
Takeoff thrust limit, as indicated by “FLX DERATE T/O” and the ACTIVE thrust
limit arrow in 2L. A FLEX temperature can be cleared and a flex temperature
thrust limit can be cancelled by pressing the CLR key, then pressing LSK 1R
anytime prior to throttle advance. Clearing a FLEX temperature entry or thrust
limit causes the FMS to revert to the maximum takeoff thrust limit (T/O).
LSK 2L - Derated Takeoff Thrust 1, T/O1 (Optional). If the Singe Derate option
is enabled, then this field will, by default, display the first Fixed-Percentage
Derate, T/O1. Additionally, this field will display the ACTIVE takeoff thrust
limit, indicated by an arrow, when a takeoff thrust limit other than T/O is selected
(T/O1, FLX DERATE) for use. If the Dual Derate option is enabled, the second
fixed-percentage derate thrust, T/O2, will be displayed here, if it 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.
