and the N1 for that Thrust Lever Angle (TLA).
Note: There is no reverse idle detent. When the pilot moves the lever out of the idle stop by
pulling up the reverse lever on the front of the thrust lever, he selects reverse idle.

THRUST RATING LIMIT
Applicable to:
, ,
MSN
The FADEC computes the thrust rating limit for each thrust lever position, as shown below.
If the thrust lever is set in a detent, the FADEC selects the rating limit corresponding to this detent.
If the thrust lever is set between two detents, the FADEC selects the rating limit corresponding to the
higher detent.

MANUAL MODE
Applicable to:
, ,
MSN
The engines are in the manual mode provided the A/THR function is :
‐ not armed or
‐ armed and not active (thrust lever not in the A/THR operating range and no alpha floor).
In these conditions, each engine is controlled by the position of its thrust lever.
The pilot controls thrust by moving the thrust lever between the IDLE and TOGA positions. Each
position of the thrust lever within these limits corresponds to an N1.
When the thrust lever is in a detent, the corresponding N1 is equal to the N1 rating limit computed by
the FADEC for that engine.
When the thrust lever is in the FLX/MCT detent :
‐ On the ground
The engine runs at the flex takeoff thrust rating if the crew has selected a flex takeoff temperature
on the MCDU that is higher than the current Total Air Temperature (TAT).
Otherwise the engine produces Maximum Continuous Thrust (MCT).
Note: A change in FLEX TEMP during the takeoff has no effect on the thrust.
‐ After takeoff
The pilot can change from FLX to MCT by moving the thrust lever to TOGA or CL, then back to
MCT. After that, he cannot use the FLX rating.
The pilot can always get MAX TO thrust by pushing the thrust lever all the way forward.

Note: Setting the thrust lever out of FLX/MCT detent without reaching TOGA or CL detent has no
effect.
AUTOMATIC MODE
Applicable to:
, ,
MSN
In the autothrust mode (A/THR function active), the FMGC computes the thrust which is limited to the
value corresponding to the thrust lever position (unless the alpha-floor mode is activated).
INDICATIONS ON FMA
The FADECs monitor the positions of the thrust levers, and trigger appropriate indications on the
FMA.
LVR
ASYM
: appears in amber (3rd line on the FMA) if, with A/THR active and both engines running,
one thrust lever is set out of the CLB detent.
LVR
CLB
: flashes white (3rd line on the FMA) if the thrust levers are not in CL position while the
aircraft is above the altitude of thrust reduction with both engines running.
LVR
MCT
: flashes white (3rd line on the FMA) if the thrust levers are not in MCT position after an
engine failure (with speed above green dot).
