Q and A time on the 737

[MorsAbAlto 19]

Still waiting on an answer to this one from two pages back. Unless of course no one knows anything about the electrical systen on the NG.

I'll try to answer.Power for DC Bus 1 is provided by TR1, which in turn is fed from AC Transfer Bus 1. AC power souces include engines, APU or GPU. The voltage ranges from 24-30V with current between 20-25A.Edit:Oh never mind. Etienne is on a spree. Edited November 7, 2010 by eddh_flyer

Oh, not at all. Thanks for joining us, Alex. As I said, I hoped someone would chime in and tell us some more about the bus load...

Big duct eh? Sorry for the blur, but those who know will recognize it anyways. :(

Bleed-air driven engine starter.

Excellent, Jim, you got it right away. :( You guys are not challenged enough... :( Let's get into some finer details maybe:We even have two things to discover here. You can find multiple instances of both on the plane... They are very small, only inches in size, but inevitable to even get the bird moving!

These are both attached to the engine case.The red arrow item appears to be the high voltage lead and igniter plug required to "light the fire". Not sure about the blue arrow item. My first thought was to say "fuel line", but secured only by a worm clamp? Electrical wiring conduit?Jim Barrett

We are indeed looking at the engine, correct. :Applause:Again, your answers are so close that I will lift it: The blue arrow is actually one of the igniter plugs, not the red one. The red one is one of the numerous fuel injection nozzles. The fuel line that goes round the engine can be seen in the middle of the picture, going from top to bottom, parallel to the red arrow and intersecting the blue one. :blush:Care for another quiz? I kinda miss the other questions as well, where are you, Jack and Dan...? :(
