BA flight lands short of runway

<< < (2/5) > >>

EHM-1883 Matt:
hmm, maybe it's just one of those special ones where there was a missing link in the plane, and it just gave up!

Hats off to the pilot;D

EHM-1703 Philip:
OK, Initial report is out from the AAIB.... Not very informative as expected but at least it is now taking the heat off the crew and pointing more towards a technical or computer issue... I can't understand why the AT requests for thrust went unanswered, that's a bit scary to only find a hole like this in the systems after 10 years of flying!!! I bet there are some nervous people around Boeing and Rolls Royce respective headquarters this weekend!

Report is available here:

EHM-1651 Christian:
Check out this but this is concerning the GE-90 engines on the B77L and B77W.

Could be the same for the B772ER aswell

The AD covering the engine software failure on the B77L and B77W

EHM-2029 Sotiris:
It could be but BA is all Rolls Royce Trent equipped.
Very very strange incident this one.
Yet it also demonstrates the safety margins to which planes are built today.
All I can say is these guys were truly amazingly lucky. At an approach speed of say 160 mph, all you need to think is what would happen had they touched land a mere two seconds earlier....

EHM-1703 Philip:
Well that report said that the particular problem occurred on take off rolls and only affected one engine although the more we become reliant on software in these aircraft the more routines and bugs there can be in the system. I would have thought a software issue would have shown up somewhere else before now with so many 777 in service and a large number of them using RR Trent 800's.

I suppose if it is something linked to the way the FADEC deals with wind shear I suppose it could be a rare problem to simulate.... It would seem from PPrune that a weather related Wind Shear or Microburst is being heavily touted as a contributing factor.

According to some sources (go to the IVAO GB forums for a source at Heathrow ATC!!) the cause is already known although the information is being kept from the public until the official report is made which will probably be months away from now! As no grounding or AD is forthcoming from Boeing or Rolls Royce one can only assume that the issue was not technical and was either Human or Weather related. (That is a rather large assumption based on not a lot of fact but rather hearsay and only holds water if indeed that "source" is correct)
