B737 Fuel Indication - Classic 737!

Fri Jan 12, 2001 11:48 pm

Do the repeaters (Refueling panel fuel gauges)...get an input from the applicable tank bussing plug.
In the schematics, it shows the repeaters getting an input from the bussing plug...but the MX manual makes it sound as if the repeaters only get an input from the main fuel gauges.

Please..if you're not sure, don't respond!!
Thanx

As far as ATA 28 is concerned, I'm getting hazier on the -200 as time passes, but the 300/400 I'm more sure of. ---- The digital fuel quantity cockpit indicators are not just indicators, but processors as well...getting all pertinent stuff ( Hi Z, Low Z, Compensator.. blah blah blah ) from it's own tank harness bussing plug and processing it to a readout of quantity. The fueling panel indicators are, as you surmised, "repeaters" of info from the cockpit indicators. --- BTW; Time sure must be passing quickly, as it sounds presumptive to my ears to call the -300/400/500 series "classic". I still consider them relatively new planes! I'm still in my 30's and it makes me feel like I'm getting old

Hi Cdfmxtech,Buzz here. OK, do you mean the -200 or -300 Guppies?
They both repeat the cockpit gauges, we're not supposed to install an underwing gauge in the cockpit.
Let's see, the "classic" swinging needle version doesn't have the processor (as NKP S2 said) and ours have an LCD read out. I don't miss tweaking the gauges on the classics, and bending over to tweak the trimmers on the bottom of the pedestal isn't as easy as it used to be on our 300/500's.
