He doesn't see the ammo counters in those images...he just sees the trim and flap settings.
Ah...
PanosGR, the instruments in AH are not historically accurate. They are generalized and standardized across the entire plane set, so that it is easier to switch between different aircraft without having to learn a lot of different instruments and measurements (feet/meters etc.). HTC still try to lay out the instruments and "skin" them in a way that resembles the actual cockpit, so in the German rides the real-life ammo counters are replaced with lookalike trim displays.
As compromises go, that is a good one.
