September 26, 200322 yr According to my 737NG notes and diagrams, the Equipment Cooling Supply fan is normally powered by 115Vac Xfer Bus 2 and the Exhaust Fan is powered by 115Vac Ground Service Bus 1 (which gets it's power from the 115Vac Xfer Bus 1). In PMDG, it seems to be the other way around. Is this optional?http://members.ozemail.com.au/~b744er/737/Bus2Off.jpgAlternate modes also seem to be back to front, power-wise. My notes tell me that the Altn Supply fan should be powered by the 115Vac Xfer Bus 1 and the Exhaust by 115ac Xfer Bus 2.For info. The Equipment Cooling Supply fans blow air into the cooling system. The Exhaust fans suck it out.Thanks.Cheers.Ian.
