Can someone kindly tell me the logic behind the smoke system entry in the 737 aircraft.cfg files? It reads:[sMOKESYSTEM]smoke.0=0.00, -7.00, 0.00, fx_pmdg737cabinsmoke.2=1, -70.000, 33.500, fx_contrail_320f //flapssmoke.3=1, -70.000, -33.500, fx_contrail_320f //flapssmoke.4=1, -80.000, 56.000, fx_contrail_320 //wingtipsmoke.5=1, -80.000, -56.000, fx_contrail_320 //wingtipsmoke.0= 16.500, -54.000, -40.000,fx_pmdgwinglightsmoke.1= 16.500, -54.000, 40.000,fx_pmdgwinglightWhat are the last two lines for? How will they work as duplicates of the first two lines? Presumably they won't??BTW, how many entries are allowed in this section? I know the limit for LIGHTS is 18: is it the same here (not that you could use 18 smoke entries, surely!).Thanks,Martin

... "How will they work as duplicates of the first two lines?"Not strictly true as smoke.1 is missed out at the beginning for some reason. But the question still stands.. :-)
