Hello again:
Have another problem. How do you set air trails for an aircraft that I have added? What are the paremeter in the aircraft.cfg?

Do you mean contrails?

Yes, wasnt sure of the name. I have no contrails for this plane that I have added and want them.

Altitude and air temp. might have an effect on things. How high have you taken this plane?

Well, about 24000feet. When I fly the default planes this high (24000), I get the contrails.

I depends on Air temp and other conditions, its not part of the aircraft. Its the sim that puts them in. Ive flown at FL300 and havent gotten contrails, and I have also flown lower and got them.  Its all about the weather on this.

What BAW said. Also, with the standard weather theme, they trail out at about 28,000ft.  ;)

The term is 'contrails'

If there is nothing in the aircraft.cfg file that directs the sim to ignore the default system for contrails, then they should display based on the correct conditions and altitude.

That can be overridden by the configuration file. Sometimes aircraft have a FX file call for contrails or changes to the levels at which the trails will display. If the FX the file was not included with the aircraft and it is listed in the file, the contrails will not display.

well i dont know about FSX (although i have it i dont have the computer for it) but the contrails might not appear because your "plane" is a prop or turboprop

try putting  

max_contrail_temperature = -25

after the

[GeneralEngineData]

markers in the aircraft .cfg

(note this works in FS9 im not sure about FSX)

Thanks to all for the input.
