Correct me if I'm wrong, but... I believe that when you're running a single engine, with any boost pump on, both pumps operate and provide 200% of what the engine needs into the fuel feed manifold. Then then excess fuel is returned to the tank of the operating side engine, via a return line and motive flow ejectors. This can easily cause an imbalance, but which is usually corrected with auto crossflow, when operating. I believe our MEL procedure when operating with an MEL'd crossflow pump is to operate with both engines running, so that the excess fuel returns to both wing tanks, instead of just one.

I pretty much cut to the chase of it with my post. But some guys were climbing out in a 76, MISmanaged their fuel pumps, had an engine (or two) quit running, got it (them) re-lit. You know, no big deal, happens all the time......
And IIRC, the number of the airplane is freaky man, freaky........

I assume the flight deck crewmembers are not aiming to become Nascar drivers. If they were, they would have made all left turns.

On the CRJ 700 you have to shut both fuel boost pumps during single engine taxi, or you get a large fuel imbalance. Maybe they forgot this and thought gravity cross flow would fix it faster. And also on all CRJs you can't sit more than 10 minutes with your lights on for cooling purposes. Sounds like these guys aren't too up on their systems knowledge. But hey, all DAL cares about is cheap feed...

That is true, if one engine has a low fuel pressure both pumps will turn on. However as 80knots said, those switches arm the pumps. If you are running single engine, your left engine off will have no fuel pressure, thus causing the pumps to run. When you deselect the left pump, it disarms the low pressure sensor and kills the pump. Thus you get the low pressure and L fuel pump messages. The right EDP provides the pressure to turn the right pump off.

This morning in RDU there was a GoJet who was sitting in the runup pad with its lights left on (while dark out, facing oncoming taxiing aircraft).
Then came the absurdity:
After sitting there for a while they asked ground if they could taxi around the airport making all right turns in order to assist with fuel crossfeeding. I have never heard of anything so ridiculous.
I was just imagining being a paying passenger on this flight. Wow.
Ground said that they could send them to a pad where they would spin around in 360s as long as they wanted. They responded "sure sounds great".
A few questions
1) Why did they even consider this?
2) How the he!! did they explain this to passengers?
3) Why did the Captain decide to leave the gate with such an imbalance? Did he have any backbone to just have the fueler fix the problem, or to call maintenance and have them deal with the issue?
Pretty embarrassing to the piloting profession. Not trying to monday morning quarterback but I wouldn't have left the gate and put passengers in such an awkward strange situation...."spinning around on a taxiway due to a fuel problem."

And you were that enraged/disappointed in GoJets and embarassed for the profession that you came right home to post it on apc. Wow

I recently witnessed a GoJet CR7 do a rotation at 2.7 degrees per second (I timed it). I cannot remember a time where I was more upset. I said to myself "These guys do not deserve to fly a kite, not to mention passengers"...
I keep submitting my observations and recommended certificate actions to the FAA, but have not heard anything yet. I will keep you all posted.
