I had a short test of the G5 instrument suit, it looks nice, but not good enough yet:
The rotation knob skips very often a menu selection, nearly unusable
Movements on the displays are not as smooth as I would expect, refresh rate too low, while rest of sim is smooth and 48 fps
Baro unit can not be set to hPa (at least I could not find how to)
Holding the rotation button to fast forward the heading bug moves far too slow
I could not get the following to work:
Selecting altitude for AP, heading or course via the menu, could not be selected by pressing the knob again in the menu while the option selected in menu. See page 16 and page 9 of the official Pilot's Guide revision D, July 2019
Missing are (as far I have seen):
Horizontal CDI bar indicator on PFD, see pages 18 and 27 Pilot's guide
VDI is implemented only on HSI, should also be on PFD, see pages 18 and 28 Pilot's guide
RNAV annunciations in HSI, see pages 23 and 31 Pilot's Guide
Bearing pointer menu is incorrect and missing features, see page 25 of Pilot's Guide
Aso unclear what source of bearing pointer is, not shown on display
OBS menu on HSI when 430 in OBS mode, see page 31 Pilot's Guide
AP bar on top of PFD
Vspeeds (Vne, Vno, Vs0, Vfe, Va, Vx, Vy, Vg, Vr) on speed tape, see page 14 of Pilot's Guide
OAT (selectable in degrees Celcius) and thus missing TAS and wind indicator
