The ATS is available in AFCS coupled (autopilot or flight director) and disengaged modes of operation.
NOTE
ATS is not available for single engine operations.

Description
The autothrottle system drives the throttle lever cables directly which, in turn, provides automatic throttle lever input commands to the engines.
The ATS is comprised of the following:
.
Computer;

.
Dual servo-clutch pack assembly;

.
Control panel, and the mode status display (MSD); and

.
Disconnect switches (ATS DISC).

Components

ATS Computer
The ATS computer is located in the avionics bay, and receives inputs from various aircraft systems, sensors and switches, and supplies power for ATS control and the servo drive assembly. The ATS performs an automatic self-test when all the sensors become valid following computer power-up.
The ATS computer only receives data inputs from the pilot’s side that includes FD 1, IRS 1, ADC 1, etc. When the AFCS transfer (XFR) mode is selected, the flight control computers use the copilot side data, and ATS operation is not available.

Dual Servo-Clutch/Servomotor
Each power lever assembly is linked to one servo-motor drive with a clutch assembly. This dual assembly is installed in the main avionics bay area, attached below the cockpit center console, and is mechanically interconnected with the throttle control cables.
The mechanical clutches, that are driven by each servo, provide identical feel to the pilot when manually operating the throttle levers with the ATS engaged, disengaged, or when overriding the ATS.

When the ATS is driving the throttles, the pilot’s throttle levers move in the same manner as if they were being positioned manually. The engine throttle levers react in unison with respect to each other’s movement, and manual operation of any one throttle lever does not affect the other.
The throttle lever friction mechanism is set at a predetermined fixed value for throttle lever operations. Therefore, adjustment of the throttle lever friction is not required, and the throttle levers do not experience any creep caused by vibration.
The throttle levers may be manually overridden when the ATS is engaged, and upon release the ATS servos resume control of the throttle levers.
