AUTOTHROTTLE SYSTEM (CONT'D)
ATS Disengagement
The ATS is disengaged automatically by the ATS, or manually by pilot selection.
ATS Automatic Disengagement
The ATS automatically disengages, and the flashing amber DISENG’D message is displayed
under any of the following conditions:
• N1 split of 13% or greater occurs;
• Either thrust reverser unlocks; or
• Engine N1 speed greater than 98.4% is detected.
The ATS automatically disengages, and displays the FAIL message, if the disengagement was
due to an auto-throttle system or sensor fault. Example: ATS malfunction detected, or aircraft
sensor input to the ATS fails.
ATS Manual Disengagement
In the even of an undesirable throttle lever event (ATS engaged), the crew manually overrides
the throttle levers and disengages the ATS by one of the following methods:
• Pressing the ATS pushbutton on the ATS control panel, the flashing amber DISENG’D
message displays and ATS servos disengage; or
• Pressing either ATS DISC switch located on the forward face of the throttle lever, the
flashing amber DISENG’D message displays and ATS servos disengage.
The DISENG’D message can be cancelled by pressing either ATS DISC switch.

AUTOTHROTTLE SYSTEM (CONT'D)
Low Speed Protection
ATS low speed protection is provided in the event that the AFCS airspeed reference is set
below 1.2 VS for the flap configuration in SPEED mode. When the AOA equivalent (plus any
AOA rate speed increment) is reached, the system uses the corresponding airspeed reference
as the target, and adjusts the throttle levers in an attempt to maintain this target. The flashing
amber AOA LIMIT message replaces the SPEED message on the MSD. Reset is accomplished
by setting the AFCS reference airspeed higher than the AOA equivalent limit speed.
Thrust Limit Protection
If the airspeed is 20 KIAS below the AFCS reference airspeed, engine thrust is within 1% N1 of
the FMS thrust limit, and the aircraft’s deceleration is greater that 0.1 knots/sec for more than
10 seconds, the flashing amber SPEED message is displayed, if the ATS is engaged in SPEED
mode.
Overspeed Protection
If the VMO/MMO overspeed warning is activated, the flashing amber VMO LIMIT or MMO LIMIT
message is displayed in the ATS MSD. If the ATS is in any N1 mode, the ATS reverts to the
SPEED mode. The ATS will retard the throttle levers for four seconds in an attempt to protect
the VMO/MMO limit, and then the servo commands stop. The LIMIT message cancels when the
airspeed is below the limit speed, and the ATS remains in the SPEED mode.
