Hello.

 

this is happening on both of my P3D 2.5 and FSX simulators on different machines.  my aircraft is PMDG 737 NGX.

 

Aircraft is stationary , parking brakes on, and when you change to different views, aircraft bounces. or ground bounces I am not sure. it is very crazy . Requesting support from PMDG for this issue.

 

I changed Mesh to other than 1m as I read from someone, but nothing changed

 

thanks in advance

 

 

This is a FSX known issue. It was fixed in the early versions of P3D but it looks like the error has made its way back. And I have noticed it also.

I've never had this with my PMDG 737NGX at any airport in FSX and I've never made that surface change at any airport. But when I get home this evening, I'll find and airport that definitely has that surface just to be sure.

Most at default airport of FSX has this problem with the surface. It happend to me while a go even with 737NGX or A320-321X. Now I use most of airport add-on fromFly Tampa or Aerosoft, etc. and this annoying thing dissapear for me. I must say that I also use REX texture direct 4 and use rex texture on ground for parking, taxi and rwy, so I haveno default texture in FSX, and maybe this is why the problem is solved for me.

Sorry but this is not a fsx bug. It has to do with the static height in your aircraft.cfg wich pmdg forgets to fix. Change static height to this and see for yourself.

 

For the PMDG 737 NGX following values should work correct:
static_pitch=-0.60
static_cg_height=8.20

 

For the PMDG 777 try this:

static_cg_height=13.70

   0

The aircraft “bounces” on the ground when I change views:
We have traced this issue to using an mesh resolution setting that is higher in resolution than 19m. These are the 10m, 5m, 2m, and 1m settings. This appears to be an terrain engine bug and isn’t something we can fix. If it bothers you, you can set the terrain resolution to 19m or lower. These are the 19m, 38m, 76m, 152m, or 305m settings. Be aware that lowering this setting can affect the use of sceneries that require the higher setting. For example many airports require high settings to simulate taxiway bridges and similar structures. If you have high resolution terrain mesh installed this will also decrease the detail of mountains and other such features if you go below the mesh’s level.

Yes i know BUT it is not true! read this http://www.avsim.com/topic/377614-ngx-bouncing-after-sp1c/ . same fix with the help of aes!

 

Try it and it is solved. and i have used this a long time in fsx and prepar3d so it works. nothing to do with mesh resolution

######! The aircrafts bounce on ground in FSX long before PMDG was even invented! This has nothing to do with PMDG, is FSX texture not compiled in "concrete".

True but as mentioned in the Manual, there is steps to make it go away. And for me it worked great. Oh btw, here is your ######! Don't want it.

once again do this and it is fixed. For the PMDG 737 NGX following values should work correct:

static_pitch=-0.60
static_cg_height=8.20

 

For the PMDG 777 try this:

static_cg_height=13.70

I will try that.  I experienced the bouncing in both products....  Anoying...

 

 

Ill let you know...

Thanks for all answers. I will also tune and inform you .

This worked for me,

 

configuring aircraft.cfg explained above..

 

for test purpose, bouncing occurred again after reverting those settings to the default . thank you.

Worked!  had several PC upgrades and OS upgrade.  I always have to use this fixes.  Dont know if PMDG is going to check at this, but it is actually woking...
