Qatar Airways Runs Out Of Gas On Taxiway?

Buddy called me and said that Qater Airways from Doha to Chicago yesterday diverted to DTW and ran out of gas on taxiway in.

Can't find it in the news anywhere. Anyone hear about this?

Looks like they did indeed divert to DTW due to weather in ORD:

Don't admit it:
Shut down left engine due to low oil pressure, unable to taxi on 1 engine due to slippery taxi ways. Request a tug to gate.
Have contractor pump 50,000 lbs for flight to original destination.
Get clearance, take off.

They did have an extended hold on taxiway Zulu after landing ILS Z 4L since Lufthansa was on their diversion gate D3.

It sounds like they went around in DTW followed by landing.

Yes, low oil pressure on left engine; flameouts do that!

Flight track shows close to 15 hrs in air and 7100 nm traveled.

Hang on - this is a thrust driven aircraft, not a wheel driven car! Slippery taxiway = reduced friction co-efficient = easier taxiing on one engine (assuming enough friction on surface to compensate for asymmetrical thrust through tiller steering angle).

"Unable to to taxi on 1 engine due to slippery taxi ways" does not compute.

Your qualifier re friction is a firm grip of the obvious. Of course one can taxi using asymmetric thrust if nose-wheel steering has traction.

So, it is unclear in your post in what way it makes it "easier" taxiing on one engine - how is this so?

Have you experienced winter conditions taxiing a large transport? If not, you should know that in some conditions, the airplane will even "sail" in a strong enough wind...(but not usually in the direction one wants!), and the only way out is to call for the tug, if it can reach you without sliding off the taxiway itself! ;-)

If I had judged the taxiways too slippery I certainly woudn't be shutting down any engines to "save fuel & hours-on-the-engine" and few would.

Back to the original point - did the engine shut down due no fuel?

Also: did they top up the oil, replace the pump and have an engineering dispatch for whatever caused low oil pressure: that is if they just fuelled up and blasted off? Oh, and clean the seats.

Sigh. One can only wish, sometimes, that this forum could revert to being what it says on the label...

What a clown, go back to your video games. Better to have people think you're an idiot rather than post something and prove that you are!

Indeed. I once saw a parked, uncrewed B-52 (490,000 lbs as it sat there) moved 20 ft backwards and 10 ft sideways (and turned a bit) by a line squall that combined freezing rain with high winds. There were a lot of guys walking around that one shaking their heads.

These conditions obtain at some point during the winter season at YUL, YHZ, YYT, YJT and other Canadian airports on the eastern seaboard.
A friend departing on a breezy day in YYT in a B-727 pushed back, tractor and tow bar disconnected, and the aircraft gently but surely weathercocked into wind making him a helpless passenger in spite of brakes being set.
Re-connected tractor and returned to the gate.

eppy certainly has no clue. The famed author/pilot Len Morgan wrote of being blown off the taxiway due ice at JFK while captaining a 747.

What does ice have to do with this incident?

Was the Qatari A/C unable to taxi due to no fuel left? Did they declare fuel emergency whilst still airborne?

curious,
FD.

FLIGHT DETENT. True. We will never know. Loss of face & all that. Like the other lot who scraped ILS aerials & App Lights on T/O. Did we hear anything else ? Nah. Middle East Yanni !

TOWER DOG ; Luv it. Old school Commander's solution. I think I learned from true Leaders like you but these days, Management are after you big time for any truly innovative thinking, "outside" of the box. We need more like you in Management !

Word is the flight landed with more than enough legal and safe fuel. The fuel ran low from the multiple hour wait, 6 hours actually, on the taxiway waiting for a parking Bay.

Nobody knows....
I do know personally one of the pilots and he is top notch, which leads me to discount some of the dumber theories.
There was mention about oil pressure? If they shut down an engine and it was slippery/icy then as mentioned controllability may have been an issue as well as being prohibited by company policy to do a single engine taxi if contaminated.
Prior to 777 I've only flown turboprops and 3 or 4 engine jets, but all were much easier to taxi with an engine shut down
