When TO/GA is armed:
On the ground (autothrottles armed and flaps not up and thrust reversers not
deployed) –
• first push (either switch) below 50 knots – activates the autothrottle in
THR REF mode
• the autothrottle will not activate between 50 knots and 400 feet radio
altitude
• pushing either switch above 80 knots disarms LNAV and VNAV.
In flight (autothrottles armed and flaps not up or autothrottles armed and
glideslope captured) –
• first push after takeoff – disarms AFDS modes and engages TO/GA;
activates autothrottle in THR REF; thrust derates are removed
• first push on approach – disarms AFDS modes and engages TO/GA;
engages LNAV if FMC criteria satisfied; activates autothrottle in THR;
thrust limit is G/A
• second push – autothrottle activates in THR REF.
Push (either switch) –
• disconnects the autothrottle (both left and right)
• illuminates the master caution lights

Boeing Proprietary 4.20.1
4.20 Automatic Flight-System Description Introduction
The automatic flight control system consists of the autopilot flight director system
(AFDS) and the autothrottle system. Both the AFDS and the autothrottle are
controlled using the mode control panel (MCP) and the FMC.
Normally, the AFDS and autothrottle are controlled automatically by the FMC to
perform climb, cruise, descent, and approach flight path guidance.
Autopilot Flight Director System
The AFDS consists of three autoflight computing systems and the MCP.
The MCP provides control of the autopilot, flight director, altitude alert, and
autothrottle systems. The MCP is used to select and activate AFDS modes, and
establish altitudes, speeds, and climb/descent profiles.
The autoflight systems provide control of the flight directors and autopilot. Flight
director information is displayed on the primary flight displays (PFDs) and
head-up displays (HUDs). The AFDS does not have direct control of the flight
control surfaces. The autopilot controls the elevators, ailerons, flaperons, and
spoilers through the fly–by–wire flight control system. Autopilot rudder
