Whats going on with my pc and P3D?

Recommended Posts

Hi!

 

Ok, so i previously made a thread about this problem as i thought the problem only occured with Carenados products. But i figured it wasnt.. I bought the following addons for my P3D:

 

- Carenado B200 KING AIR

- Carenado PC12

- Carenado B1900D

- Wilco TBM850

- MILVIZ B350i

 

So my problem is.. Every time i start with one of these aircrafts, the engine runs for about 30 seconds, but the displays inside the aircraft looks like they are in the start-up phaze. But the aircraft start rolling during those 30 seconds. Then i put parking brake on. Then when i try to start the engine(s) again, the aircraft will start rolling again, up till around 20 knots. And it also sounds like the engine is going full power.

 

This cant be normal right? It takes away all the realism with the aircraft acting like this.

 

So what i've tried so far is:

*Reinstalling the aircrafts.

*Reinstalling Windows and P3D

 

I dont have any joysticks connected, or joystick drivers installed. (i had the same problem even with that installed)

 

My speccs are:

Windows 7 64-bit
Processor: AMD FX™-8350 Eight-Core Processor (8 CPUs), ~4.0GHz
Memory: 8192MB RAM
DirectX Version: DirectX 11
Card name: AMD Radeon R9 200 Series (4 GB)

 

Can someone out there please help me? You might have a solution that i could try? I feel like i wasted so much money and time on this if i cant get this to work :(

There is a bug in P3d 2.4 and possibly before this that shuts down turbo prop engines when you load them, even if the previous aircraft flown was running with engines on. It appears at first that the engines are running but in fact they are on idle power and ignition is off. So what you are seeing is the engines running down. I believe P3d 2.5 will/has fixed this. In the meantime, the only way to load  turboprops with the engines running is to save a flight then reload that flight in which case your engines will be fully functioning. Otherwise load the aircraft and perform a start up.

Thanks for fast reply.

Im already running P3d 2.5 and the problems still occours.

 

I've also started the planse cold & dark, and when i turn the engine on, the plane will start rolling in about 20-30 knots and full power, even when the throttle is set to neutral.

I can't help i'm afraid but the same thing happens to me,  i have to flick the throttle up and down on my Logi Stick to disengage throttle.

Thats exactly what i have to do aswell. Its really annoying!

Can i ask what your pc specs are?

I used this fix and it helped.

Thank you Vic.   I'm downloading 2.5 as i type so i will try this myself.

I was really crossing my fingers after i tried that solution. But it didnt help for me. Plane even stars rolling really fast with parking brake engaged. Thanks though!

Ok, so im guessing it hasnt something to do with our hardware since we got different parts.

Don't know if it makes a difference but I always start cold and dark. Then go through the startup routine. The "fix" has worked on all the turbo's I've tried it on. Play with the setting.

I tried many different settings, but my plane just keeps rolling with high rpm. If that was the problem, then everyone would have the same problem as me and we would see loads of threads like this one.

 

I just dont understand why these aircrafts works for some and for some other it doesnt.

I might have misread the Op's question. I thought you were talking about P3d and engines not started when loading an aircraft. If you are saying the aircraft is "running away" when you first load it, then the most likely cause is the condition lever is high when you load. On some aircraft this effectively raises the idle power of the engines, and creates forward thrust.

 

I would not recommend fiddling with the Beta or prop angle in the aircraft cfg because doing so might interfere with other parameters the developer probably worked hard to tune.

 

Usually the solution is to apply parking brakes as soon as you load the aircraft, keep the power levers idle and if there are condition levers keep them on low settings. Sooner or later the engines will settle down.

Well, your post did make sense though. Could sound like the problem im having.

 

As soon as the aircraft is loaded i do the cold and dark option (if its possible for the plane). Then i do a fast start up with every one of the power levers on the lowest adjustment as possible and also parking brake engaged. The plane still runs away....

Both FSX and P3d have hard coded turbo prop start up routines. Unless you write incredibly complex custom coding to defeat this, turbo props, especially those with less than massive propellers, can over-speed on start up. One way to stop this happening is to radically slow down the engine response to power, but that throws up other problems.

 

We spent hundreds of hours stopping this from happening in the Duke T V2 by very careful modelling and some custom coding.

 

However I don't think it should be as bad as what you describe from the list of the aircraft you have. Try shutting down then starting with auto start (CTR E) then watch what the auto functions do. I can't see what you are doing so it is hard to judge but did you see the bit about the condition levers? On most turbo props they affect power/idle settings.

Thanks for explaining!

 

Well, when i do the checklist for my PC12 it says "CONDITION LEVER - GROUND IDLE" and thats what i have it on. Even with that the plane just runs away.

 

The King Air 350 that comes with P3D works perfectly. But the MILVIZ B350i doesnt. How come the MILVIZ version run away but the P3D default 350 doesnt?

Just did a little experiment. As i mentioned in my previous post: Default B350 works, MILVIZ B350 doesnt.

 

So i copied the propeller settings from default B350 aircraft.cfg into the MILVIZ one. The MILVIZ didnt run away.. So that must mean something right?

 

@Robert: Im already in contact with Carenado, but they had no idea so they gonna investigate. They told me first to change Mesh resoulution etc. But that obviously didnt help.

I think the key to starting a turboprop is to have  the park brake on, the Condition lever fully aft, start the engine, and at 10-15 ng crack the cond lever, the engine will start and the ac wont move, then when it is up to normal , increase tthe CL to max.

Thanks for your reply!

 

The numbers on NG just shoots up to like 100 no matter what kind of position the condition lever is in. This happens on all the aircrafts.

The Milviz KA-350i is still an "Alpha" project, and is being updated quite frequently. In fact, I just completed compiling new installers for both FSX and P3Dv2 versions.

 

I've found that I need to set the "condition lever(s)" on my CH Yoke way below Ground Idle. In fact, I just barely crack 'em open. One other thing is that for some reason both FSX and P3D will completely ignore the initial positions of the prop lever(s) and assume they are set for full fine...

 

...I have to rapidly cycle the prop lever(s) fully forward and back again before the sim will respond to them.

 

What version are you running right now?

Great!

 

Im running P3D v2.5 if thats what you ment?

 

But i can read reviews about some of the airplanes ive bought, so since the ratings were great the planes must have worked for the testers. And since also the user Poppet has the same problems it must be really random that it works for some and for some others it dont.

 

 

PS: Im really grateful that you guys trying to help me! :)

I've got the PC12 and I've seen these issues before.

 

If you use Carenado's cold and dark settings it seems to generate this response when you load a plane.

 

Here's my suggestion:

 

Load the plane at any airport, select Carenado's ready to taxi settings.

 

Shut down the plane following the Checklist.

 

Save the flight as the default flight.

 

Next time you load a new flight use the scenario screen to pick you airport.

 

Follow the start up Checklist especially as it pertains to condition lever and PCL settings. Should not overrun anymore.

But this doesnt happened only when using the Cold and Dark settings. It happens the moment i load the aircraft. Boom, and it runs away. Then the engine stops, and i start it again it will run away from me again.

 

But if i follow your advice, will i be able to chose where to park at the airport? Or will the plane just load from where i saved it?

 

And thanks btw!

If it happens when you're loading the aircraft, that means you're saving the default flight with the engine running. Try starting flights without the engine running - see how it behaves when you start up the engine following the checklist, as I mentioned in my email.

 

Once you have a default, shut down flight saved, you can select whichever airport and location you want, the point is that you have FSX/P3D saved in a state where engines are shut down and systems are turned off, but not via the "Cold and Dark" button method.

 

Give that a try and see if it helps.

Wow, that actually works! Thank you man!

 

But is it normal the NG is rising up to like 100 when starting the engine? And it really looks like the plane just wanna run away, but thanks to the parking brake its not.

 

Since this solution works, isnt it possible to find the source of the problem?

 

Anyways, thanks again!

No worries buddy.

 

Can't say I know exactly WHY it does that... it might have something to do with the way the turboprop model is hardcoded into FSX/P3D.

 

Unlike jets, and I believe unlike pistons, a lot of the turboprop engine modelling is hardcoded and can't be changed without using custom variables outside of the sim. This is probably some sort of byproduct of the mixture/auto-feathering prop control logic.

 

It's not normal to spike up to 100% - it is normal to spike up to something like 70-75% (not that in reality it should do that either).
