Aircraft slowly moving forward, throttle idle

Post by dikkeduif »

Hey guys,

Enjoying this aircraft, but one thing is driving me nuts and I'm not sure it's something I'm doing.

The plane is slowly creeping forward when I'm on idle throttle, with parking brakes AND wheel chocks in place. I'm using p3d v4 on windows 10.
It's a fresh install, I just got the plane 2 days ago. I started noticing it when I was entering data in the GPS. And now I can't unsee it :)

When I press the toe brakes it's the same, it just moves forward slowly. I would imagine that with the wheel chocks in place and parking brakes it shouldn't move an inch.

Any idea what's going on here?

Thanks
Donald

Hi Donald - welcome to the forums. :)

This is actually a pretty common complaint: unfortunately it's a longstanding issue with the FSX/P3D platform itself. For a recent discussion (and one possible P3D workaround) please have a read of this topic.

Cheers,
Nick

Ha thanks Nick!

Before you replied I booted up p3d and tried with the 172 and indeed I had the same issue. Wow I never noticed this before. :)
I'll try doing the ctrl shift p command as you suggested.

What a weird problem, you would think they had fixed this in p3dv4 by now :)

Some time ago, I believe Austin Meyers from Laminar Research gave an explanation for the issues faced by simulator designers, and in his case for X-Plane in particular, when it comes to ground friction. They have to account for static and dynamic friction coefficients on a variety of surfaces under different conditions.

They have to account for rolling resistance, side loads under changing loads.

I believe the designers of FSX came up with some compromise solution that doesn't provide quite enough static friction, but is good enough while on the roll. They probably figured that we generally don't spent all that much time sitting still on the ground with the engine running in our flight simulators! :)

Yes its just a platform limitation to work and live with as it was.

thanks,

Thanks for the insight! I guess it's telling me to spend less time on the ground, and more time in the air ;)
