When do contrails appear? Force vs. Default.........

I cannot remember, do jet contrails appear automatically in FS2004 based on atmospheric conditions in the sim, rather than just above FL300 automatically as in FS2002? I have an entry to force contrails in my jet fleet cfg files when temp falls below -30C but I am wondering if this is realistic. Is there a default contrail entry in the .cfg files or not?Appreciate clarification. Sorry for going over previously covered ground.Thanks!JS
