Heres a suggestion to PMDG, why can't PMDG install exhaust fume visibilty from the back of each engine as the fuel is burning through the magnificent engines, that will further make the aircraft more realistic, thanks.Rayek.http://www.precisionmanuals.com/images/for...argo_hauler.gif http://i37.photobucket.com/albums/e62/ritz...tishAirways.jpg http://i37.photobucket.com/albums/e62/ritzer82/untitled.jpg

Well modern fuels do burn much cleaner now, although maybe the aircraft.cfg will allow a smoke section to be added.somebody did create a heat haze file on avsim for the 737, which I quite like, maybe he will write one for the 747 in time.Happy contrails Steveps The biggest realism improvement for me would be a weather radar. But I think it won't happen until FSX at least
