Turbo Bonanza Manifold Pressure

@kevykevtpa
Hi,
I own the bonanza now for some days and have made some nice flights with this stunning addon "plane".But I also recognises some strange damage incresase or loss of engine condition.
I flew nearly 2h (straight forward) with full engines set (full throttle and prop) with no effects to the engine condition.Otherwise I was flying in the alps with cruise setting between the mountains and valleys with 20% decrease of engine condition in 1/2 an hour (many curves and "stick pulling").
As far I could investigate this it seems to me that giving positive G-force to the plane has an enormous effect to the condition decrease. No matter if you level off a descent or flying long steep curves.
As soon as you apply some force to the plane by pulling the stick it affects the engine condition much more than any engine mismanagement. -
@voice-of-reason Thank you Voice, or whoever it is I'm talking to LOL... So far no recurrance of the manifold pressure issue, and I've even tried, so... Tis a mystery for now anyway.
Now I'm off to fly the Baron, been looking forward to that especially as an alternative to the stock one, which sorta sux.... #justsayin
Still haven't found the TC POH, so hello world, if anyone has one or knows where to find it, short of buying it, please let me know! Haven't looked for the Baron, though I may have from when I was flying the stock version.
But now with these two GA beauties, I may never fly an airliner again! And someone (I don't remember who just now, brain dead after trading stocks all day) published a really nice KTPA so that made me happy, too, just look at my name to know why LOL...

Just for info:
It seems that this is really a bug in the addon, triggered by the cylinder temperature management in some way. The support is aware of this and will repair this in the next patch for the Analog Bonanza.Happy landings,

Hello,
I have exactly the same problem with the Bonanza. In level flight, the pointers of Manifold-Pressure and Fuel-Flow always wobble back and forth. No matter what I change on T P M, the back and forth wobble remains.Then I saw this topic and wanted to record a video of the problem. In the next 2 flights I have then made, the problem did not occur.
So far I have not found out when the problem occurs and for what reason.
-
There are several things that ended up being discussed in this post, including the degradation of engine condition due to rapid pitch changes (a byproduct of my cylinder cooling calculations). Since I know this has been fixed and made public since then, I know the Bonanza went through another round of testing before that release, which did not reveal anything anomalous with the manifold pressure and fuel flow. I also have not seen anything suspicious while developing the Bonanza Professional, which uses some of the same fuel flow simulation code.
As I said in a previous post, I am happy to look into this further, but a video of the fluctuations would really help me diagnose the problem. If you can provide that, I am more than happy to take a look!

Ok, here is a video:

That looks like severe fouling to me. Have you tried resetting the engine condition on the weather radar display while you're seeing that behavior? Alternatively, you could monitor L:var_engineFouling for the amount of spark plug fouling.
-
That helped, thank you. Engine condition always showed 100%, so I never bothered. Watching the LVAR showed a value of 23 (which I assume is quite high lol). Repairing the engine reset it to 0. Started to build up again at low RPM. Stopped increasing when leaned. Decreased in flight with mixture set to rich. Indications are normal now :)
Guess I need to do some more reading on the EPM800...
-
I'm glad that was an easy fix for you. This is why I implemented the tablet interface for my standalone aircraft. There is so much going on under the hood of those Steam Gauge Overhaul aircraft that most users are probably completely unaware of. On the engine visualizer of my standalone piston engine aircraft, that fouling would be indicated by red bars partially covering the sparkplugs. All of this and more will feature in the Bonanza Professional, which you will be able to get at a significant discount, as an Analog Bonanza owner. Happy flying!

I am really looking forward to this aircraft, as the A36 is currently my favorite aircraft in the sim. Can you confirm one thing for me, namely that the BK ADI and HSI have updated exterior dimensions, 3.55" W x 3.37" H.
Edit: The screenshots look really good, so I believe my question has been answered..
Thanks!
