GENERAL
The autothrust (A/-rHR) is a function of the FMGS, it includes 2 independent A/-rHR
commands, one per FMGC. Each one is able to control the thrust of both engines
simultaneously through 2 engine interface units and 2 electronic engine controls (IAE
engines) or 2 engine control units (CFM engines). Only one FMGC controls the active
A/-rHR, it is called the master FMGC.
Thrust is controlled :
- automatically when the A/-I-HR is active
- manually by the pilot.
The autothrust is active when the A/-I-HR pushbutton of the FCU is lighted green and A/-rHR
is displayed white in the FMA 5th column.
The position of the thrust levers determines whether A/-rHR is armed, active, or
disconnected.
The autothrust system, when active :
- maintains a specific thrust in THRUST mode
- controls the aircraft speed or MACH in SPEED/MACH mode
- uses ALPHA FLOOR mode to set maximum thrust when the aircraft angle of attack
exceeds a specific threshold.
The autothrust system can operate independently or with the AP/FD.
When performing alone, A/-FHR always controls the speed.
If the autothrust system is working with the AP/FD, the A/-rHR mode and AP/FD pitch
modes are linked together. (Refer to 1.22.30 Interaction between AP/FD and A/-rHR
modes).
When autothrust is active, the FMGS commands the thrust according to the vertical
mode logic, but uses a thrust not greater than the thrust commanded by the position of
the thrust lever. For example, when the thrust levers are set at the CL (climb) detent,
FG can command thrust between idle and max climb.
The autothrust system, when armed, automatically activates if the thrust levers are
moved into the active range sector. Outside of this range, thrust levers control thrust
directly.
