Unrealistic single engine taxiing

Recommended Posts

Does anyone else have this problem? After a single engine landing or shutting down an engine while taxiing to the gate, I almost need full power on the other engine to taxi. Starting on one engine is completely impossible. This is quite unrealistic. Has the pmdg team noticed this or is there a fix or anything? This is the only big problem I could find, by the way. Love the product!

No. With one engine idling it looks realistic, but when I shut it down completely, the plane is stuck to the ground. It shouldn't be a problem. A lot of airlines shut down one engine three minutes after landing.

The ground contact model is one of the many shortcomings of FSX. Even if the friction model wasn't broken, you still won't get realistic single engine taxi because the asymmetric thrust will mean you have to turn into the running engine, which you wouldn't need to do in the real thing.

 

PMDG have done remarkable job but this is just one of the things they can't fix and you'll have to live with it. Sorry.

This worked fine in FS9 with the modified sim1.dll why can't the same be done for FSX?

 

So much good stuff missing from FSX that worked perfectly well in FS9...

Well I just checked with FSLabs and they claim to have fixed the friction issue completely with FSX

Ye olde scandinavian demonstrated single engine taxi in one of his beta videos, I don't remember him using full power to get the plane to start moving.

Yep.  Only a little thrust to get it going, and not much else.  It was a little higher on thrust due to the ground contact model, but definitely not crazy unrealistic.

Pete Dowson recently fixed the ground friction problems in FSX within FSUIPC. However PMDG do not want to make FSUIPC a requirement for installation so they won't use, or take any account of, the friction corrections that are now possible. In fact PMDG regard such mods as hacks and refuse to include them, even though this "hack" corrects a bug in the original software, so it's actually a patch, not a hack. I think this is great a shame, but that is the position.

+1 to that.

I applied the FSUIPC friction fix myself, and the results are very good. You give it a little start bump and that's all, it goes nicely on idle thrust. It takes into account your weight aswell, makes taxiing much more realistic, and goes with every plane nicely.

Do you need the Payware FSUIPC for this?

No, it works in the free version too. You just don't have the ability to customise it. It's either on or off.

So how do I turn it on? (I'm a complete FSUIPC noob)

First, make sure you have the latest version downloaded from http://www.schiratti.com/dowson.html. It comes with an auto installer.

 

Then open the 'modules' folder in your FSX root folder. Open file FSUIPC.ini using Notepad, or similar text editor.

 

Add the following line to the General section.

 

PatchSIM1friction=Yes

 

It's fully described in "FSUIPC for advanced users" a PDF in the 'FSUIPC documents' folder.

Anybody noticed with the friction script (or even not with the script...i've only flown the 777 with it turned on) you only need autobrake 1 and reverse IDLE to stop, and even then it seems like you stop way too quickly for such a heavy plane?  

 

I've never had to use autobrake 2, 3 etc and i don't even need to use more than reverse idle.  Even with a MAX payload.  Landing usually with 6-9 tonnes of fuel.  

 

Is this right?

Reverse thrust makes no differance to stopping distance, it is not even factored into the landing perfomance calculations. Autobrakes modulate, your Vref and whatever you added on top will affect your stopping distance on a dry runway

Thanks from me, don't know how I missed this one .

The friction patch reduces rolling friction and braking effects, so if anything It should take longer to stop with it active. I can't say I've noticed the 777 is too easy to slow down. It feels normal subjectively without any objective measure to compare with.

The only problem that I have with the FSUIPC fix is that when the plane is light, it starts rolling and continues to accelerate when the throttles are at idle.

That's correct for light aircrafts. Sometimes you need a little bit more than idle thrust (for example: when you are on a sloped ramp)
