To any (friendly) airbus pilot,
could someone tell me the working of following annunciators on the FCU display :
LAT indication
ALT indication
LVL/CH indication
HDG or TRK indication
VS or FPA indication
The question really is when do they become active and more when do they go off
In many videos i have seen taken in the cockpit the HDG and V/S are always on when HDG/VS (middle indicator) is on and
the TRK and FPA are on when TRK/FPA button is pressed and the TRK/FPA indicator (middle indicator) is on .
I mean HDG and VS or TRK and FPA are on depending on the system used on the FCU.
Is this correct or are there other situations that can turn them off or on?
LAT indication seems to be always on ?
LVL/CH seems to be always on ?
ALT indication seems to be always on ?

PS : difficult to explain without proper picture
PS : the reason of asking is that Project Magenta software switches the LVLCH only on when climbing to new altitude
or descending
ALT indication on only when target altitude is reached
V/S indication only on when climbing/descending in V/S mode (not in open climb, open descent, managed descent, managed climb)
HDG always on when not in TRK/FPA mode
LAT always on
