Cabin environmental bug - see video
-
@Black-Square I seem to have discovered another issue.
If you want to try to reproduce this:
I took off from KMIA heading to KDAB, everything normal. Cruised at 24,000ft. Descending at ~1500fpm, nice slow cabin pressure descent of ~700fpm. I had the intercooler bypass knobs pulled out as they should be in a high altitude cruise. I had the cabin thermostat set to 68 deg F the whole flight. During descent, I bumped the cabin thermostat up to 70 deg F and instantly the auto heat logic decided it was broiler time. I pushed in the intercooler bypass knobs and it reverted to normal behavior. ECS master mode to Off for 10 seconds, then back to auto heat, thinking this may reset the logic. Started recording this video at this point. Pulled out the knobs again and the auto heat logic said again "Let's broil the cabin!" I pushed them back in and it went back to normal again. -
Once again, thank you so much for the video. That's the most useful tool when troubleshoot anything like this.
That one looks like the correct behavior to me, though. The intercooler bypass has the power to melt components in the ducting system without any help from the combustion air heater. To quote the reciprocating engine Duke pilot the first time I delivered him my software to test, "Ok, make sure both of those are in before start so we don't kill ourselves." The reason the heating vent heats up faster and hotter than the plenum is because the plenum air is the source for the heater. The heater always has the ability to raise the temperature of the plenum air, so naturally, it will be hotter. I hope that one made sense? As far as I'm aware, everything is working correctly in that situation, but I will add this to my list to test next time I have the simulator open. I typically test many things at once, so this will be one of them :)

Thank you BlackSquare for bringing me a twin turboprob. This turbine Duke is fantastic! I have been using the pad as well to learn the details of the heating and cooling. Well done!
Quick question… Are the valves for the pilot and copilot air flipped compared to the defrost? With the defrost lever pushed in the valves on the pad are closed. When I pull the lever they open to provide air to the windshield. But the pilot and copilot valves are open on the pad with the levers pushed it. When I pull the levers out for those two they close.

Oops disregard I just read above that some valves are push to open and others are pull to open.
