Autothrust (A/THR) The autothrust function performs these modes:
-speed: acquisition and hold (SPD)
-Mach: acquisition and hold (MACH)
-thrust: acquisition and hold of thrust limit (CLB or MCT or TO/GA)
-retard: application of minimum thrust (IDLE) during flare.

Flight mode annunciator (FMA) The FMA on the upper section of the PFD provides the pilot with status data related to:
-engagement of the modes of the A/THR, AP and FD systems
-landing capabilities.
This section of the PFD comprises five columns of three lines each
which display the various operations of the FMGC.
(Ref. Fig. 008)
The FMA uses different colors for the display of the annunciations
and the messages.
These colors are :
-green for active modes
-cyan for armed modes
-magenta for modes armed or engaged because of a constraint

-white for engagement status of AP, FD, A/THR. The display flashes in case of automatic switching of the FMGC
-amber for indications which require special attention.
The following tables show the different messages with the associated colors (G for green, C for cyan, M for magenta, R for red, A for amber, W for white).
