TRU Voltage and Cold Starts

[jmarkows]

I have been rereading the 146 manual again and trying to wrap my head around the Electrical system chapter. Just for kicks, I loaded up the 146 tonight, connected ground power, and switched to Cold starts. It was above freezing where I am, maybe that makes a difference, but I'm wondering why I'm not seeing the TRUs outputting 35V when I have the Start Master On and Start Power set to Cold. See here:

Apologies, I had to scale it down a bit to fit in the 4MB attachment limit, but it should still be readable.

From the manual:

I would think the voltmeter would be showing 35 when TRU1 and TRU2 were selected, but it never goes past ~28V. I tried selecting an engine and hitting Start to see if spinning up an engine would make a difference, and it does not.

This is probably incredibly picayune and I feel bad for even asking, but I ended up down a rabbit hole so here I am.

I did also see TRU1 taking the brunt of the starting power compared to TRU2, I'm not sure if they should have approximately the same load or not.

Yes,

The TRU voltmeters should show ~35V with cold start selected.

To be honest, I'm not sure if we ever simulated Cold Starts as we considered them outside the scope of normal operations. I've logged this to our internal trackers though to see if we can support this in a future update.

Thanks Mark.
