Possible bug: "AUTO COOL" holds cabin temperature at cruise level
-
I feel this might be a bug: in hot weather, on the ground, set the climate switch to "AUTO COOL". Start a flight and climb to 25000 ft.
What happens: cabin temperature goes down from outside temperature to the dialed-in temperature (in my case, 21° C). The cabin maintains that temperature at altitude, even though the outside air is below freezing.
Expected result: without looking at the schematics, I believe the cabin should get colder over time as the aircraft climbs into colder air?
This affects the Turbine Duke, maybe all variants.
From the manual:
The heating and cooling modes will only EITHER heat or cool the cabin, not both. This requires the operator to switch from heating to cooling when the desired cabin temperature is below the outside air temperature, or from cooling to heating when the desired cabin temperature is above the outside air temperature. -
While I'm at it, a few other issues that make me wonder whether they're working as intended:
• amber "LEFT/RIGHT OIL DOOR CLOSED" annunciations during cruise and while oil temps are healthy; isn't that when the oil doors should be closed?
• Piston Dukes: opening and closing cowl flaps does not seem to be reflected in the engine schematics on the tablet
Requests:
• something seems awry with the pressurization system, or I don't understand it works and how I'm supposed to use it. More information in the manual would be appreciated.
• Having the tables with the Engine Power Settings on the tablet or somewhere in the cockpit would be really helpful, especially in VR.I love the Dukes. Excellent work, good Sir!

You are holding the open/close switches, yes? It's not a momentary switch that will fully open or close the cowl flaps, the flaps only move when the switch is being held in open or close, and it takes a bit to fully open or close. I have seen them move on the tablet, but it's fairly slow.

@brennan it s what said the manual aswel !
"While this may be frustrating, it is accurate to the real
aircraft. Full cowl flap actuation time is approximately fourteen seconds. Similar to setting flaps
in older model Cessna aircraft, the switches must be held for the approximate duration required
for the desired setting. Since this is tedious in a flight simulator, an invisible switch is positioned
between the two cowl flap switches that will actuate both cowl flaps at the same time"about auto cool it has been evocated in two thread already such as https://community.justflight.com/topic/6529/in-cabin-ac/5?_=1716302155216
or also on this thread where a bug was found and Nick have been able to reproduce so it should be fixed for the next update.
@DxMarovitch said in Cabin environmental bug - see video:
@Black-Square I think I have caught the ECS in the piston Duke misbehaving. Hot out on the ground, running the AC. Take off, climb, it gets cold out. Somehow, despite still being set to auto cool, it's making heat.

yup it s the part I painted in red, behind the 4
once closed
if it doesn't close, maybe check if the fuses are pushed in :

Thank you for chiming in with all these great answers, everyone.
Indeed, the issue with air conditioning from your original post has already been reported and fixed.
As for the pressurization system, there are two full pages on pages in the manual on the system, and I've done tutorials on the Just Flight YouTube channel in the past for aircraft with nearly identical systems. Please let me know what you're looking for, and I will be happy to explain, and add information to the manuals, if necessary. I'm always here to answer questions!

Fuses are in. The tablet reports 0 failures. And I get a (short) audio cue of the electrical motor engaging (when appropriate).
Here's what I do to reproduce the issue:
• I start a flight with the Piston Duke, cold & dark at a parking spot.
• I turn on the batteries.
• I open the tablet and switch to one of the engine pages.
• I verify the Cowl Flaps are shown as open (exactly as in your first screenshot)
• I press and hold the appropriate switch so it moves forward into the "CLOSED" position. (Alternatively, I use the hidden clickspot to close both sides simultaneously.)
• I count to 30 and keep holding.
• I release the switch(es). The cowl flaps should now be closed. (If I use the switches again, the audio cue does not play.)At no point during this process does the Cowl Flap display on the tablet move or animate or switch into a different position.

And on the aircraft exterior model, do they effectively close or remain open?
As a reference, here are two screenshots :- open :
- close :
(edit : Sorry, I just noticed the YouTube title, so I guess the 3D model itself has no issues...)
I tried on my end without being able to reproduce.
Right now the only issue I may think of is an issue with the install process, :-/ have you tried to perform an uninstall / reinstall ? - open :

Sorry for the late follow-up. The modelled cowl flaps were always open, they didn't budge at all, and they were matching what's visible on the tablet -> control issue.
While the audio cues for the electric motor gave me a false sense of working controls, FSUIPC interfered for SOME reason. I didn't have cowl flaps assigned to any hardware controls, but FSUIPC inherited the calibration settings for cowl flaps axes from another profile. When I turned that off (ie. when I reset the calibration settings for the unassigned axes), the cowl flaps started working.
Thank you, Nicotine, for pointing me in the right direction with the images of the open and closed cowl flaps. I never checked their state, for some reason I had this idea that the cowl flaps were internal and I hardly pay much attention to the outside of my planes unless the dev forces me to do a walkaround. I learned that I can actually observe the left-side cowl flap from the pilot seat.
