Buses map B737/B738 NG

[Euclidessn]

Hi..

I'm pilot of b737/738. During ground training we usually hear about some problems that crew use to deal beyond the QRH scope during flight, regarding electrical failures. I think that if the pilot could have a reference of equipments that are conected with respective buses, it should be usefull to figure out what equipment he will loose in the case of bus failure.


For exemple, we had a situation in one airline where a failure in the battery bus cause the two pack lights to iluminate. The pilots spent some time to understand why it was happening and had some doubt about the pressurization control, because even reestoring the power for that bus, pack lights were still iluminated due to section 2 of the bus remained with a tripped cb.
