If I look at the checklist for the Mooney, after engine start it specifies that the throttle be set for 900-1000 rpm. At that setting, the engine does not shut down.

I haven't checked this against the actual poh, but it does suggest that the correct throttle setting is above its minimum. Kind of odd, but there it is. Perhaps someone who has actually flown this aircraft could provide further information.

Thanks.

Ahhh. That is odd that it never done it before, but I will give that a try. Thanks for the info.

So it is still broken after all this time. 

I don't think it's broken. As far as I know, idle in the real plane is between 600-700 rpm, so I think it's normal for the engine to stop below 600 rpm.

Any aircraft I have ever flown one of the preflight checks is to pull the power back to idle and make sure the engine keeps running. If it doesn't I am staying on the ground.

This is a bug. In real life you must be able to idle the engine without it dying... think about it. On landing you idle the engine. On descent at times... The engine should never die at ANY throttle setting. Mixture yes, not throttle.This is indeed a bug. 

 

You idle an airplane at a specific RPM to avoid fouling plugs, keep it smooth, etc. But on most run ups, an idle check is actually specified. If you have carb heat, you idle with carb heat on, which really drops the RPM to the lowest it can be. Anyways, the Mooney is broken.

Exactly. Any aircraft engine that stalls when pulling the power back is a accident waiting to happen. 

I noticed the new bug immediately.

Throttle all the way back causes the engine to shut down.

EGT is still not working properly.

Overhead lights still do not work.

Two months from now they will issue another fix, most likely.

This Mooney doesn't seem to be conventionally aspirated, so there's no carb heat, or at least I haven't found it. I never operated such engines with carb heat on during taxi in real life, but maybe I was doing something wrong. For those a/c with carburetors, the carb heat check is done during run-up at the same time that one does the magneto check, but that's carried out at some intermediate rpm setting, not idle.

But that's not relevant. I tried to kill the engine at idle at KEYW (i.e., at sea level) and I can't do it. The engine purrs along at 620 rpm, so one may need to lean the engine out at higher altitudes. With regard to idling performance in the air, the rpm never gets below 1000 rpm due to the airflow over the prop, so there's no question of the engine dying at idle throttle. The check list does call for idling at 900-1000 rpm on the ground, however, so that will take some throttle manipulation.

BTW, if one finds the idling behavior annoying, just tweak the extremity dead zone on the throttle axis by a few percent and that will keep the in-sim throttle slightly above the "dead zone". In the meanwhile, if anyone has experience operating a real life Mooney with this engine, it would be great to learn about its behavior at altitudes away from SL. Does one need to lean a bit to keep the engine running on idle when on the ground?

Correct. Continental IO-550 is fuel injected.

I've experienced this with the default C172 (engine cut out at idle throttle).  While it really doesn't excuse a 3rd party publisher, I suspect the problem is in the default code.  I've learned to compensate with non-standard procedures (i.e. leaning the mixture after engine start).  Carenado has a history of shortcuts on aircraft systems, so I would suspect they are just using built-in code, which is obviously flawed.

I just took the Mooney out for a (night) flight, and was impressed.  The aircraft did not stall at idle, the fuel selector works again, the interior flashlight was turned on and proved very handy (left alt+L), and there was darn little I could find fault with.

The toe brakes seemed a bit underpowered, but the rudder steering worked OK on the ground, so I was able to navigate across the airfield. 

The instantaneous reacting EGT gauge seems a bit hokey, but does help with leaning the engine.

The GTN750 was welcome and is nice for simple navigation tasks like choosing a DTO destination.

The autopilot worked OK, but the UP/DOWN rocker appeared to have no function.. instead, the altitude preselector did the job.

All in all, a nice set of conventional gauges in contrast to my standard Turbo Bonanza and its G1000.

The Carenado C170, Seminole and now Mooney appear refreshed after the last set of updates and all worth flying again! 🙂

Have not flown the C182 and am wondering why I bought it (maybe because it was out first..) 😉

It is fuel injected, it would have alternate air not carb heat. I was talking about during the run up you put the carb heat on and bring the power all the way back to make sure it still runs. Best practice is you do your mag check at whatever RPM, you then check your carb heat... with the carb heat still on you then bring the power to idle. It should Idle fine. Then put your carb hear to off, and your rpm should jump up a little bit. This is the best way to check these things. You would not use carb heat during taxi. 

I have not tested the sim Mooney yet. I don't know that the engine would die at higher alt with mixture rich. Typically it will idle at mixture rich, and you would lean for take off. 

I know now why my engine was cutting out when on idle.

It looks like this latest update broke my TPN controller settings. When I push the throttle there's now a delay. The Prop & Mixture controller are also affected by this latest bug.

This sim and these updates are a PITA. I'm glad that I no longer buy any add-ons for this sim.

 

The rudder trim indicator bar still disappears if you zoom out far enough.

Well, I just tried it ... and ... A/P appears to be borked, or at least it's not working they way I'd expect it to. Can only climb/descend at 500fpm.

You don't know how to work the autopilot climb mode apparently.
