B767 Fuel qty indicators fault
I had a blank indication in total and right tank after leven off. QRH do not say anything about it. Is it a good idea pulling circuit breakers? Did anybody have The same fault and how you manage it?

A blank tank and totaliser display can be an indication of a short circuit in one of the tank level sensors (or a multiple failure/contamination) of two or more tank sensors.
I don't think you can isolate the short circuit by pulling one circuit breaker (There are two CBs on P11 for indication). You would probably need to pull both to remove power from the tank sensors, but then you would lose your good tank display. Of course, you should never reset fuel system CB's in the air. Note: If the fault goes away by itself, the display should restore. I would seek advice from your airline on this issue. Rgds NSEU |
Is it a good idea pulling circuit breakers? As a rule. No. Pilots shouldn't be fiddlin' with CB's at all. No. Not a good idea at all. * Unless you're really up the creek and improvising is your only hope for a paddle. .... AND you know what you're doing! |
Thank you so much for The answer, The airline is doing The investigación.
