A319/A320/A321 engine controls – thrust control operations
Limited thrust parameters (N1 for CFM56, EPR for
V2500) computed by FADEC.
Selection of thrust limit mode obtained directly by throttle
position :
Six positions defined by detents or stops.
Thrust lever only to be moved manually (no
servomotor) : lever position not necessarily
representing engine thrust delivered
According to the thrust lever position the FADEC
computes :
- Thrust rating limit (no TRP)
- N1 (EPR) when in manual mode
- N1 (EPR) which can be achieved in

A319/A320/A321 engine controls indications on PFD : FMA
8.15
The following indications may appear on the PFD Flight
Mode Annunciator (FMA), in upper left corner :
ASYM : Only one thrust lever is set to CLB or
MCT position,
CLB : Flashing when aircraft above thrust
reduction altitude and thrust levers
not in CLB notch,
MCT : Flashing in case of engine failure if the
non-affected thrust lever is not set at
MCT,
A-FLOOR : α -floor condition encountered,
TOGA LK : When leaving α -floor condition and
thrust still at MTO
