need track replay Random fuel system problems

[Foka]

I saw two different fuel system problems and I wildly guess they're connected, so I'm posting them in one topic, but I can't bu sure.

1. In our group we had two instances that centerline drop tank didn't feed fuel. Inner tanks worked ok, but drop tank was full and not feeding. EXT TANKS switches where to NORM, then checked to OVERRIDE.

2. I peronally had it twice - random fuel low alert mid flight. Last time I made a screenshots:

 

 

Both bugs are completle random one in dozens of flights, so unable to provide tracks or reproduce.

We will watch for it, but we are going to need a track replay showing the issue. 

thanks

I found track to 2nd problem - it was small MP mission, maybe it'll work.

AFAIR MC went off around middle of the mission... Judging by ACMI around time 1:05-1:15

Checked the track and of course it's messed up, my plane crashes on take off... Great tool these tracks...

They are very useful for sharing steps for reproduceable bugs. Not so good for sharing hours and hours of flight.

So they're not so good for shraing random, hard to reproduce bugs.

Unfortunately not. 

Back to the original bug, was the fuel bit initiated before or after the fuel low caution appeared?

No.

I notice FLBIT is boxed, any chance the advisories are residual from the BIT? Best I got until we get a trk.

Edit: missed Swift's comment

It wasnt a yes no question, it was an either or.

I can see that the fuel bit has been initiated by the Boxed FLBIT on the fuel DDI page. 

Activation of this BIT will cause a master caution and FUEL LO warning to appear on the Left DDI within 13 seconds, these cautions will remain for at least 1 minute and will be removed as the BIT concludes with the FLBIT automatically being unboxed.

If you are certain that you aren't activating the FLBIT manually, then it might be a double click issue as the FLBIT pushbutton is the same as the pushbutton to enter the FUEL page

So probably I hit the button even not knowing it. I didn't bit test by purpose.

It probably was it.

So, from my initial list only #1 is unresolved

Centreline tanks not feeding eh? Bleed air off, fuel probe not fully retracted, Weight on Wheels. Any of those?

If you see it happening again, screenshots videos tracks etc all help
