Hi,

Recently when I was departing ESSA an early morning I noticed I had a zone temp in CONT CAB after pushback, which i was able to resolve. Now, my question is, I had been sitting around on the ground for about 30 mins (ish), with the packs off, but it was 0 degress celcius outside, so how was that able to trigger the zone temp after I pushed back? I mean I had the packs running for about 2 min from when i started the APU until I turned them off again for Engine start, and I had already turned the CONT CAB to a little colder temperature because that's what i normally do. Also I assume this has something to do with the fact that I sat on the ground for almost 30 min which I normally don't do (and normally i dont get zone temp :P), and therefore i got the zone temp this time?
So, would that have been able to happen so easily in real Life, or did I do someting wrong? Or was it just the PMDG trying to claim to fame (lol)?

You posted this in the Hangar Chat. If you go on the main forum page and scroll down, you'll find the PMDG support forums. You'd be better off posting it there since they're more likely to see it there. Do bear in mind that they do require full names on their forums if you do post there. Alternatively, you can submit a support ticket to them regarding your inquiry.

As far as I know this is an erroneous alert. The NGX has many of the real 737's quirks modelled like the door lights sometimes coming on after engine start.

Also, I know that United used to turn off trim air while at the ramp for some time because they were having trouble with the zone temp light coming on after engine start. They waited until after engine start to turn on trim air. This issue has been resolved, however.
