Analog Caravan Engine Behaviour
-
Hi Everyone,
I recently bought the Analog Caravan to have a 208B that operated realistically in MSFS.
When I was buying it, I was under the impression that one of the main aspects of upgrades over the vanilla Caravan was in regards to how the engine operated. I understood that this addon overhauled engine operation to a realistic standard.
However after about 20 hours and nearly a dozen flights, I repeatedly see that some behaviours I would expect of a "realistic" turboprop engine simulation do not manifest themselves. Namely, ITT increase with altitude and residual heat.
I am in a flight right now over Southern France and have climbed at max-power to 22,000ft with the engine getting colder and colder as I climb.
I have also witnessed engine heat resetting to ambient after each shut down.
Additionally I also keep seeing the engine temperature exceeding well over the redline in every startup, when in real life it barely even reaches it with starts over 16% Ng.
I am not questioning the integrity of the promotional material, but I am starting to suspect that somehow, despite the cockpit looking like I am using the correct addon, I am actually experiencing vanilla Caravan engine simulation.
Does anyone what could be the issue and this might have happened?
I am using default livery that came with the install.Assistance is appreciated.
Edit: Don't know if this is relevant but I just noticed the default liveries that come with Analog Overhaul install looks the same once I start a flight, no matter which one I choose.

I took the Turbine Duke out for a spin and I'm having the same ITT decrease with altitude (despite speed also going down) behaviour in it as well.
I've literally firewalled the throttle, at 24,000ft and the temperature keeps going down, despite losing 50knots since 5000ft.

@KosmicRavioli Thanks for getting in touch (that's a great username).
Here is briefly how I was going to answer your first message, but then your second message raises some questions:
The Analog Caravan was my first PT6 simulation, and each successive aircraft has received significant improvements as I've learned what's possible in MSFS. While I would have to look at exactly what's simulated in the Caravan (I wrote the code almost four years ago), I am not surprised to hear some of these limitations. For instance, I know I wasn't simulating residual heat at the time (that debuted with the TBM), and I know my starting simulation was also not as refined, and produced the temperature spikes you're seeing (debuted with the Dukes and back-ported, if memory serves).
Now, your second post is more interesting, because all these features are included in the Turbine Duke. You should be well over the ITT limit with the power levers firewalled at 24,000ft. In fact, if we look at the performance tables in the manual, we can see by the shading that we become ITT limited somewhere in the neighborhood of 20,000ft. I have one possible thought, although it might sound a little silly. Have you checked the condition of the engines? As they begin to decline below 25%, their power output will decrease, which would probably also decrease ITT, and lead to a loss of airspeed.
If you're still having problems with the Turbine Duke, please feel free to send me videos or screenshots, and I can help you troubleshoot from there.
