‐ ECAM “ENG THRUST LOCKED” flashes every 5 s
‐ ECAM displays “THR LEVERS......MOVE”
‐ A single chime sounds and the Master Caution light flashes every 5 s.
All warnings cease when the flight crew moves the thrust levers out of the detent.

The standard disconnection triggers a temporary ECAM message and a single chime.
The non standard disconnection (A/THR pb pressed on the FCU or A/THR failure) triggers
continuous visual cautions until the flight crew reacts. Single chime sounds.

A/THR MODES
Applicable to:
GENERAL
Except in takeoff and go-around situations, normal operation of the A/THR system requires the
thrust levers to be:
In the CL detent for the four engine configuration. If they are not ‐ set in the CL detent, “LVR CLB”
flashes white on the FMA.
‐ In MCT detent when in one-engine-out configuration. If the other levers are not set in the MCT
detent, “LVR MCT” flashes white on the FMA.
The A/THR modes are automatically selected in conjunction with the AP/FD modes (except for
ALPHA FLOOR):
A/THR in THRUST mode AP/FD pitch mode maintains the speed:
OP CLB - OP DES - CLB - SRS - FLARE and DES (IDLE
path)
A/THR in SPEED/MACH mode If neither AP nor FD is engaged.
If AP/FD controls a vertical path:
V/S - FPA - ALT* - ALT CST*- ALT - ALT CRZ - G/S* - G/S - FINAL
and DES (geometric path)
A/THR in RETARD mode Automatic landing (AP engaged in LAND mode).
Applicable to: ,
GENERAL
Except in takeoff and go-around situations, normal operation of the A/THR system requires the
thrust levers to be:
‐ In the CL detent for the two engine configuration. If they are not set in the CL detent, “LVR CLB”
flashes white on the FMA.
‐ In MCT detent when in one-engine-out configuration. If the appropriate lever is not set in the
MCT detent, “LVR MCT” flashes white on the FMA.

If AP/FD controls a vertical path:

and DES (geometric path)
A/THR in RETARD mode Automatic landing (AP engaged in LAND mode).
Applicable to:
THRUST MODE
In THRUST mode, autothrust commands a specific thrust level in conjunction with the AP/FD pitch
mode. This thrust level is limited by the thrust lever position.
FMA display Meaning
THR MCT The most advanced thrust lever is in the MCT detent (engine-out)
THR CLB The most advanced thrust lever is in the CL detent
THR LVR Thrust levers are either below CL or MCT detent, or at least one thrust lever is in CL
detent and the others above CL detent
THR IDLE A/THR commands IDLE thrust
THR DES A/THR commands a reduced thrust while DES mode is engaged
