Engine Malfunction - Looking for advice
-
Hello, I’ve had the Caravan Pro for a couple of weeks now, and it has become my favorite aircraft in MSFS 2024. I’ve flown it for around 48 hours over the last few days, and this happened to me yesterday (video attached). I’m trying to figure out what I did wrong.
I was adjusting the propeller RPM and power, and suddenly I lost the engine. I think the ITT was in the yellow range on the gauge, but that’s not unusual when I try to squeeze a bit more performance out of the aircraft during long flights.
What surprised me the most was that the STANBY ALT INOPT indicator came on, and when I checked the aircraft tablet, the engine didn’t seem to show any failures, at least I think so.
Any suggestion or idea that could help me learn how to avoid this or fix it?
Thank you very much. I love this aircraft, and congratulations on an outstanding product.
The YouTube link is unlisted; I couldn’t find any other way to send it.

Thanks for the video. That's always immensely helpful. Given that my tablet shows no engine damage, and you received the message on the screen, this appears to be a failure triggered by MSFS 2024's native wear and tear system. The only alternative is that this was a MTBF catastrophic engine failure, which should statistically only happen once in every 500,000 for the Caravan. Unfortunately, your video didn't show the failures page, because that would have been useful to rule out.
Do you have v1.1 of the Caravan? I eliminated one source of the MSFS 2024 wear and tear system causing interference with my aircraft in that update. The native wear and tear system is largely a black box to us developers, with little guidance as to what configuration parameters and variables are used to generate damage, so it's entirely possible that there is something else interfering that nobody else has hit yet. I will try to reproduce this later with the near-redline ITT myself.
In the meantime, enabling "disable airframe stress damage" in the MSFS menu (yes, airframe stress damage, not engine damage...) should prevent this from happening in the future.

Unfortunately, I wasn't able to reproduce this, but I'm interested in the ITT discrepancy I observed between my testing and your video at the same configuration, including the bleed air valve and ambient air temperature. I saw 705°C ITT, and 290 PPH FF, compared to your 785°C and 380 PPH FF. That's quite the difference! Also, your elevator trim is almost against the nose-up stop! I'm so confused, haha.

I was in autopilot (GPS, ATL HLD, I think). The plane was working weird since the takeoff, It feels heavy to lift. I never push it to hard on the climbs (I'm new to sim flying) but this time something was off. I have the bleed air valce open working to keep the cabin at 21C, vents on, the stanby alt was on (this is very confusing to me, I really dont know how it works so I always turn it on because of the anunciator light), fuel was flowing at 4 in the dial and the ITT was reaching yellow (I'm really afraid to push it pass green). I think the elevator get stuck in that position because i disengage the autopilot and never try to trimmed manually.
As I stated I am pretty noob on modern sim flying XD, but do a lot in the past (Falcon 4, MSFS 2000). I flying with hotas and rudder pedals.
It was the first and only strange behaviour the aircraft have, for me. Is a beauty and I love it.
Thanks for all your help.

@Black-Square Thanks! I would check that setting. I always record the flight if anything else happens. I have the latest version of the plane. Thanks for the response.

@Black-Square sorry, is "disable aircraft stress damage"? Thanks.

@Senor55 Yes, those are the right settings. That should prevent MSFS 2024 from failing your engine for any unexpected reasons. Please stay in touch if you notice anything else strange. Maybe some others here will have an explanation for the discrepancies that I haven't thought of yet.
