LUA dynamic friction mod 737NGX

Featured Replies

With FSX people used this ground friction mod, including me with FSUIPC. Is this still needed with P3D?

I have recently installed it and I love it.  It works wonders for the 777 

Unfortunately that bug is still present in P3dv3 so yes i use it and its the bomb, not only do the PMDG suffer from GF IMHO all aircraft do in some way... and a dab of thrust with full fuel/pax/cargo and the big iron rolls nicely and turns much better in regards to taxing...

Thought this was not needed with PMDG?

Not under P3D v3, I thought too.

I can find no appreciable difference between V2 and V3 without the mod.  It makes a noticeable difference on the 777 during taxi. No longer a need to boost the thrust leavers to keep it rolling.

PMDG 777/NG for me is always a very light fuel load under 10% for the 777 around 20-25% for the NG

 

I need very little throttle to break away and taxi is just about idle in the 777 and around 23.5-24 mark for the NG. Not saying it's right or wrong might be a better topic in PMDG 777/NG forum and hear from some of the real life 777 pilots.

 

Just not convinced its the way to go. Like most things it might be down to personnel taste.

With this LUA the 737-800 starts moving slowly with the throttles at idle.

( FSX 737-800 modified for Project Magenta and P3Dv3 )

 

I tried to find more about it on the IN but found only Pete's comment that indeed a 737-800 starts moving with the throttles at idle..

 

Anyone has more info on that ?

I'm using the MOD but i deleted the ROLLING entry line at set friction

Can you tell me why you did that ?

David, I think that really is the point.  None of us are truly qualified comment on what is accurate behavior or not unless you are type qualified.  The behavior with the mod 'seems' more accurate to me on larger aircraft types.  Like most here,  I have only been a pax on the 777 many times over and I have never heard the engine spooling on a straight taxi run,  I have however felt breaking quite often in order to slow the aircraft down.  From my frame of reference, this is what is represented using the mod.

The problem with using the FSUIPC mod with the NGX is that PMDG have already adjusted engine thrust at low N1 so that taxiing thrust and breakaway thrust are representative. This compensates for the higher friction. If you apply friction is reduced so now the engine thrust is too high and the aircraft will roll with very little extra thrust. On system with the mod enabled, the fully loaded -700 won't move at idle but begins to move at 22% N1.

 

However it's still worth using the mod because the lateral tyre forces and contaminated runway effects are much improved. you can adjust the effects and choose which you want to use. So you could keep the rolling friction as it is and have the modified sliding and/or braking effects. Best of both worlds.

Great.  I didn't realise that there were optional  parameters.

Since I've never been  on a 777 Erich I enjoyed your insight.

 

I don't have a reg version so I would get all or nothing. But don't have anything to lost to try it out, so I might as well try it.
