ITT really hot
-
I am in cruise, the checklist says throttle should be 97% TRQ, 840 ITT, and 1600 RPM. I have no problem maintaining the RPM, but my ITT gets to 840 at only 57% torque.
I have no anti ice on, inertial separator closed, all blowers low, etc. I am at 35,000 feet. No failures, and I followed tutorials and they all seem to have much more power in cruise.
Here are some images:

Ah ok, and what is it supposed to be? Is this normal? Also not related to topic but where can I find the VNAV button? Is it "DESCEND" on the autopilot?
-
@Sunake one final question, the manual doesn't explain what vent/cable heat is, is it engine intake heating? I am currently flying through clouds and am worried about icing.
-
It's not supposed to be, those are the various cruise limits, you will be limited by one (or multiple) of them, and at altitude it's usually ITT. I think the typo being corrected is the fact that the checklist says Climb Power.
I had the same question, but yes, as altitude increases, torque must decrease to keep ITT within limits. Less air (and also fuel) available for cooling.
Vent/Cable heat switches are for engine control cables (maybe also fuel vents) are are located on the pilot's side under the yoke to the right, below the various pitot heaters. Next to the intertial separator switches (not very clearly labeled) if you know where those are.
-
I would have to check, but it is probably heating for the fuel vent and cabling that runs from the cockpit and the engines and/or flight controls, so you can leave those ON along with the pitot static heats. :
You generally don't have to worry About icing. The starship will automatically deice itself. The only thing you have to manage is the engine anti ice, the bottom left 2 switches on the ice protection panel. You switch those on when you are in icing conditions or other precipitation or if you're operating on the ground in like a dusty environment or something.
What it does is divert airflow into the engine in a way that allows debris that enters the intake to get thrown out of the engine without getting into the compressor.
You can see if there is any FOD that might be entering the intake on the tablet engine pages at the bottom

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

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.
