    Also, sorry but I tried messing around with blowers, cabin heat, and i could not figure out how to raise cabin temperature. It's stuck at 57 fahrenheit and cooling slowly, I've tried using manual and auto temp mode, auto seems to do nothing regarding my CKPT/CABIN AUTO TEMP dial, and yeah, my passengers are complaining that it's really cold. And on the cabin temperature in the screenshot I sent, the heat line on the left is not heating. It also doesn't look like AC COMP is on, I don't know what that is.

    The manual also mentions this might happen and what you can do, but I'll tell you anyway. Set the bleed air valves to high flow. That will help temperature controller to cope. But it will cause a slightly higher fuel burn so if you're max ranging the aircraft this is something to consider as you might end up a little short on fuel.

    Edit: or maybe it doesn't affect the fuel burn. I'm sure it did on my first flight but not the flight I'm currently doing. Maybe the temperature controller on my current flight isn't having a problem with keeping the cabin warm so selecting high flow for me has no effect.

      I suspect that the initial step is to turn the bleed air on for OP

      As to your edit, I don't think it affects burn rate much, but it will reduce available power/increase ITT slightly IIRC.

        Bleed air is on, but the AC COMP is not running and the heat that is supposed to heat cabin and defrosters is not going, however the pilot and instrument heat is going, which is bad because its heating the instrument panel but not me. https://postimg.cc/PpW1gXtX

          It's not having an effect on the ITT for me either. So I suspect it's because it doesn't need to work hard since it's not that cold where I cam right now

            @Sunake was correct, the fact that your cabin temp is highlighted in red shows that you cannot manage that temperature with current settings. Bleed Air High is your only option because of how cold it is outside.

              Set the bleed air valves to HIGH FLOW. I can see in your screen shot that the temperature target is in RED which means the system isn't able to keep up. Setting bleed air to high flow should give it the airflow it needs to warm the cabin.

                @Sunake The problem is... https://postimg.cc/dZqkyGGd bleeds are already in high flow. Although over the past 20 minutes or so the temperature did rise by 2 fahrenheit.

                  According to this screen shot it is in BOTH. you need to move the switch all the way to the right to HIGH FLOW.

                    @Sunake Oh no, thats my bad, I didn't see that position, sorry. Also, is there any way to heat the cockpit, but not overheat the instrument panel? Also, closing outflow valves would be nice so I don't heat the avionics bay too. I can cool the panel using the alternate avionics blower because otherwise the panel just overheats.

                      Well by turning down the cabin/cockpit temperature, you can regulate the air temp going into the bay where the displays are. That will help it. I spent a good portion of the day yesterday in the air with the Starship, and with a cabin temp of 70F the displays were hanging about 105, with the forward avionics bay in the 60s or 70s depending on outside air.

                      And I don't think the air actually dumps into the nose bay, I believe that is solely open to the outside air by way of the forward fans and rear vents, I think the graphic is just there because there's nowhere else to put it.

                        I don't believe so, the remedy if the instrument panel starts to overheat and starts showing a red overheat message on the CRT displays is to turn the temperature all the way down and set the fan blower speed to high and turn on the alternate blower. But right now I'm at FL330 and my panel temperature is at 119F/48C with the alternate blower off and I'm not worried about it.

                        But if you want to keep them cool then just run the alternate blower all the time.

                          @jmarkows When I turn down the cockpit temperature, the temperature flow is still the same as the cabin. Should I set the selector to manual or auto? Also, how do I turn on the AC compressor? It doesn't seem to be on.

                              Yes I am. You only need to worry if you see your screens starting showing you an overheat message which if you don't resolve that soon they will switch off to cool down.

                              Be sure to give the manual a read, it's a great way to pass the time on longer flights. And try to get the real world star ship manuals, you can find them via Google. They give a lot more info.

                                The flow will be the same, yes, but it should start changing color on the tablet to indicate it is cooler. It is mixed back in the environmental dome and then the regulated air is piped into the cabin and cockpit. Leave it in auto; manual is for when something fails, unless you enjoy also having to tinker with the Temp increase/decrease switch to manually change the mixing valve position.

                                The AC compressor is not on because you the desired cabin temp is higher than the outside temp. It will automatically turn on when needed. It is only used for cooling.

                                  The AC compressor is for cooling. So it will run when it needs to cool the cabin to a target temperature. The temp mode should be in AUTO 99% of the time.

                                    The flow will be the same, yes, but it should start changing color on the tablet to indicate it is cooler. It is mixed back in the environmental dome and then the regulated air is piped into the cabin and cockpit. Leave it in auto; manual is for when something fails, unless you enjoy also having to tinker with the Temp increase/decrease switch to manually change the mixing valve position.

                                    The AC compressor is not on because you the desired cabin temp is higher than the outside temp. It will automatically turn on when needed. It is only used for cooling.

                                    @jmarkows Only thing I don't understand is why is there a seperate control for cockpit temp and cabin temp if both of them are the same, because all the climate control air is pumped from the environmental dome?

                                      @slipperfruit Look at the tablet; the cockpit air also gets piped directly into the instrument bay as well as the pilot/copilot air vents. Cabin temp gets piped into the cabin, but can also be blown into the instrument bay with the aux blower.

                                      In practice, I'm sure the cabin/cockpit differential works about as well as modern cars where the passenger tries to set a different temp from the driver 🙂 but the important part is the cockpit air temp gets blown right into the bay with the displays.
