I have an Aspen + ACU2 wired to the IFD (as it was to the 530W before it). In my settings the ARINC 492 port connected to the ACU2's out is set to 'EFIS/Airdata', not 'Honeywell EFIS' as the install manual recommends. I think this is because we changed it from Honeywell EFIS to EFIS/Airdata when we added the ACU2 two years ago as that made the 530W pick up the new air data sources. When I upgraded to my IFD540 the installer just copied the settings from the 530W. I seem to get air data as I have a wind vector and VSR. But I see no heading bug on the IFD.
I have Aspen's 2.6.5 software loaded as well as your 10.0.3.0 software on the IFD.
Should I have it changed to 'Honeywell EFIS'?
