[Released] Wing42 Boeing 247D

You can listen to the variables and logs them in a doc. Then you can use those variables to link an input. For example I have linked two levers to each oil cowls so my life with this plane is much easier!

I will see if I can find the oil consumption variable and monitor it in flight… ■■■■ … So many things and not enogh time …

First result, flight of 1.5 hr:

Morning flight, and I loaded SAE20W oil, which is good up to 50F. As the OAT climbed with the day, to above 50F, oil consumption increased. I climbed higher, and oil consumption decreased to 15 lbs/hr or so. Haven’t tried longer flight yet. I may add more parameters. To me this all looks OK.

God, the only serious problem that I see is the price we pay Wing42 for this Jewel.

Thank you Wing42

Indeed, Thank You Wing42!!! :ok_hand: :airplane:

Did you take note of the oil quantity when this occurred ?

While it may indeed just be just a bug, the other possibility is you were running at settings where the oil consumption is known to be very high (the massive oil consumption at certain settings may itself be a bug) and you just ran out of oil.

In fact, I suspect a lot of the unexplainable fires and engine failures recounted in this thread may be a result of running out of oil.

Possibly but most of mine came when I ran the oil temp over 100 for any length of time
I keepit under 90 now and haven’t had an engine fire since!

I did not run out of oil. I didn’t really have an engine fire nor and engine failure. The oil temperature just changed suddenly and I was kind of lucky that I caught it. Opening the oil shutters fixed the issue.

I was running at app. 27” manifold and 1900-2000rpm. Mixture leaned

Piperdriver, what route where you flying, and where approximately did it happen?

One handy addition here might be a mechanic’s logbook - I’m still mixing oils so the last-used oil grade isn’t quite as handy as it might be normally, so a log showing how much of what has gone in the tanks would definitely help. That’s just a nice-to-have thing though!

Edit: just did a complete oil change after a ground run with deliberately assymetrical oil temps - after oil change & restart, still got asymmetric oil temps.

Has anybody observed the occasional gauges going berserk? I’ve seen it 3 or 4 times in maybe a total of 15-20 flights where all of a sudden, and for no apparent reason that I can associate it with, the needle of every gauge in the cockpit will start jumping erratically back and forth. It only lasts a second or two at most. I imagine its happened many more times than I’ve noticed because unless you happen to be looking directly at gauge panel it would happen and you’d never notice it. There usually is however a slight change in engine RPM that seems to recover quickly. And if I recall, on at least one of those occasions I’d just made a slight change to the throttle position which may have led to the cause.

I’ve only noticed them do that when there’s been a ( thankfully rare ) stutter - every now & then there’ll be a tiny pause, the sim recovers, another tiny pause and then business as usual. Gauges will go a bit nuts briefly, probably to do with syncing bits of the sim up again.

My fuel flow gauges are always jumping around. I have yet to be able to successfully start both engines and I suspect that is related. Looking at the LVARs I can see them jumping around as well, so the gauge behavior is a manifestation of what the underlying system is doing. I’m also seeing what seem to be extremely high values in the various resistance LVARs. Without knowing how the implementation works, I can’t say for certain that they are wrong, but given that on my machine it takes far longer to get to the point where the flywheel can mesh and the fact that the engines appear as though they are full of sludge when trying to start, I am very suspicious. All of this happens with a clean community folder, so no idea what the problem could be.

While I think the problem is the aircraft and not me, I did do a video showing how I’m attempting to start. If anybody is willing to have a look and can point out something I’m doing wrong, that would obviously be great.

I’ve had a support ticket open for the last month and haven’t heard back, but I suspect that Otmar is still underwater and I’m hoping that whatever is happening to me is connected to some of the other engine behaviors being reported and will shake out with the first update. Someday, I would really like to actually fly this airplane. :).

I think you have your throttle too low. I can’t see your rpm because you moved the camera away, but the first time you started, it stayed on for a bit then stopped. That tells me your rpm may be too low.

Thanks for having a look. Prop levers are full forward and I’ve tried variations of throttle all the way up to 50%. Various youtubers have been successful with the same throttle settings I generally use (which was 20% in the video IIRC), and the engine never even fires, so I don’t think that is it…

Hmm. I’m not sure what flight control you are using, but maybe remove any bindings related to mixture or magnetos? I’m wondering if something is interfering?

In the video, I was using no bindings at all. I normally use FSUIPC and the Thrustmaster Airbus stuff, but FSUIPC wasn’t loaded and only keyboard mouse profiles in MSFS were non-empty. As I type this, I realize I can disable my keyboard profile as well. I’ll try that for completeness (and I don’t have any mouse bindings for mags/etc.). I’ll also try disconnecting the controllers when I do this.

Piperdriver, what route where you flying, and where approximately did it happen?

I was flying in southern Australia I think. I’m not 100% anymore. I’ll try to figure it out by looking at my logbook.

Have you tried reinstalling the aircraft from scratch?
