It's only  the standard sanitary dump pressure valves (SDPV's) kicking in, that's only legal over oceanic airspace buddy






Or perhaps it's a just a bad videocard driver or directX version  ;D

Can I remove it, somehow?

That's some rate of descent!

Well Im not surprised, those 737's are past their best-by date anyway  ;D .

I had the same problem and I cant remember if I fixed it reinstalling FS2004, deleting fs9.cfg and letting a new one be built, or reinstalling a video driver. Give each one a try and see what happens

Ok, i have 4 fx_contrail_... files 2 of them are 5/14/2003 and 2 of them 7/15/2004 and 7/12/2004.

your problem is exactly what dave has said your contrails file has been altered the only way to fix this is to put back the orignals.
You only need 2 files

Hi Gogi,

Ok, i have 4 fx_contrail_... files 2 of them are 5/14/2003 and 2 of them 7/15/2004 and 7/12/2004.

Could you post the 4 file names including the extension (i.e 'fx_contrail_s.fx').

Cheers,
Dave

Technically they could, if they had the right shape.

contrails are to do with engine exhaust not shape. Or so i have been told all these years. The vapour trails are to do with the wings and so on when there is high humidity
