Hi all....can anyone shed any light. I cannot find much or any info on items lost if you are to loose the dc bus 2. There is a little info on the B737.org site but VERY limited. Anyone out there that can help?? Why do you loose TR2 TR3 ? Very confused!!
Cheers

TR1 and TR2 fail mainly because of the lost of AC systems which are the primary source of power for TR's.Hydraulic A and Fuel pump aft are tied to AC bus 2 but i'll check the rest and update u on the rest

there used to be a diagram on B737.CO.UK (Chris Brady's site) showing all the items lost.
