Cold start VDI is active

[AH_Solid_Snake]

Not sure if this is a bug but previously during cold starts the VDI would start in an inactive state while the alignment was running. When it finished and started showing the cow pats coming towards me it was a good visual cue that we’d switched over to nav.

Now the VDI is in that animated state from the moment I switch it on?

I've noticed the same behavior starting at least two OB release ago, not sure what was the number.
I'm even not sure it's a bug or not, but definitely for a pilot it was a good reference to understand if the alignment was completed or not. Personally sometime I miss the jester voice confirmation on "ready to taxi", and that was a good backup.

We have to wait a confirmation from heatblur or a real pilot on this.

Yeah I noticed this too, before it would just be completely black with only the heading tape and pitch ladder + horizon lines present, and then when the INS mode was set to nav, you'd see it fully, with the green sky and darker green ground with the animated whatever they are.

Now the latter is present from cold.

Hopefully HB will be able to clarify the correct behaviour.

As a side note, I noticed that at night, the angle-of-bank marks are illuminated red even with a cold and dark aircraft without power and with the VDI turned off.

Put the HSD into TID Repeat and it'll show you the RIO's alignment gauge at the top, which references how far along the process the INS is.

I wasn't asking for help with alignment just noticed a difference that wasn’t in the changelog that i recall. The older behaviour makes more sense to me.

We reviewed the available sources and diagrams very carefully again, and we found that the data flow from the AHRS to the CSDC and then to the VDIG doesn't even need the WCS to be powered. In other words, when the INS is off, the VDIG (VDI + HUD) uses attitude and heading data from the backup source - the ARHS - which is always on.
