Always dangerous to make blanket statements like that. It just invites a flurry of pics depicting how wrong you are for this particular a/c, that nation, or period of paleo-geomagnetic oscillation.
I'll stand by my statement. Please feel free to provide any evidence, pictures or whatever you have that shows an aircraft liquid filled compass.
If you were heading south, in an actual aircraft the compass card would
look like |!21!|!|!S!|!|!15!
In AH it looks like |!15|!|!S!|!|!21!|
in either case to head East, you'd turn left. The AH representation is more intuitive, but not accurate. It’s presented the way it is for the now flying public.
