As I fly at a constant 5000 ft with OAT at 6C, every few minutes I have to adjust my mixture just a tad in and out because the rpm drop very low. Then I set it back to where it was and everything is fine for a few more minutes. Until it happens again. I set the mixture to where I get the most rpm, and leave it, but this happens every so often. Didnt do this before.

Can confirm. Like all the bugs related to avionics, autopilot and controls, the occurrence is unpredictable. I haven't seen this bug since 1.93, but I wouldn't be surprised that if on my next flight, it shows up.

I didn’t even think leaning was working. It doesn’t work in the sr22. Mixture does nothing until you pull it far enough to cut fuel. 

The real problem with mixture right now is broken logic. As you lean mixture fuel flow never increases only EGT should increase until until it peaked. In MSFS you can see fuel flow actually increased as lean and when you close to peak fuel flow start decreasing. This is fundamentally wrong  ! Of course how much we pull mixture knob or lever depends on altitude. IRL we lean mixture during taxi 

1. Leaning G1000

2. Leaning during taxi

 

Yes, mixture and fuel flow seem to be way off.  What I find is to just lean until the RPMs drop, then rich a little to get back to max RPM.  You get the power you'd expect, but you'll burn a lot more fuel.  Good thing simulator fuel is free.  I'm hoping it gets addressed in a patch soon.  

Has always been that way since ages ( I'd say since fs5 ).

Mixture leaning just reduces FF right from the begining at sea level. Then as you climb, there's an intial increase in FF and only after a while it starts dropping...

Apparently ASOBO ported the reciprocating engine logic from previous versions of the sim 😕

Yes that seems right - although I hadn't seen quite as much "reverse" fuel flow readings when leaning as in FSX. This coding flaw has been present since probably before FS2004! If you issue a new product or mod you get grief sometimes for not "fixing" the mixture but there is little you can do except mitigate the worst of it. You can also cheat by using simvars or xml files to trick the user into thinking 45% mixture is 55%.

I don't think it would take much energy to finally fix it as it is after all just altering parameters in already existing hard coding, but it needs someone who has access to source code to do it.

PLEASE TELL US you’re at least “thinking” about getting back in the aeroplane business? One of my sharpest regrets leaving P3D will be losing my RealAir aircraft forever.

I will still purchase from Sean if he ever shows up, but he may have burnt a bridge or two... so you’re the half of RealAir with untainted appeal...

Fingers x’ed!

It would be fantastic news to get the Dukes and the Legacy for MSFS, ideally, with RXP avionics  🙂🙂

@Bert Pieke and @robert young

Bert and Rob-

I would not presume to know the arrangements, but I’d imagine anything Rob does would have to be a totally new project, separate from the prior RealAir collaborations. 

That said, I’d echo your sentiments EXACTLY Bert.

Fully agree.  Fully!

I'm working hard on the FS2020 Bonanza turbo mod at the moment and it's taking up all my spare time. My health is not great so no going back to Realair type of work - besides which I'm a flight model and sound specialist, not graphics or systems. I would not be capable of a conversion without very easy tools and they don't exist at the moment. But the Lancair Legacy is my favourite project we ever did and Sean did a fantastic job on the modelling and gauges.

Rob-

EVERYTHING you two produced was superlative. Stay healthy, and if and when you can share your talents with us, I shall be grateful. Excited to hear about your MSFS Bonanza work... do keep us tantalized...

Ta- C

RealAir, in any sort of way, present in MFS would be an EXCELLENT source of energy for us prop / turboprop lovers :-)
