Is that true?How much fuel need to dump for the plane to land safely?How fast can it be done and at what rate?
The amount of fuel has to be dump .... Fuel will be dumped until the aircraft can land with its Maximum Landing Weight (MLD) Usually the Maximum Take-off Weight (MTOW) willl be higher then MLD in order to carry more fuel for the flight. But since they only had just used 5 minutes of fuel for the 8 hour flight . They need to burn off LOTS of fuel in order to land safe
Yup, engine no 1 could not be shut down and they tried water injection to shut it down. Possibility of debris that caused the hole in the wing severing off vital lines to the engine. It also lost significant amount of hydraulics on one of the system. In fact, the cargo doors could only be opened around 11pm plus. Brought to the ICU(hangar) sum time after.
A380 MLD is at around 391 tonnes. MZFW is at around 366 tonnes. It probably would have needed to jettison 60 plus tonnes off. Just a guess.
SQ resuming A380 flights today (Friday) according to that BBC report....more worrying that there was an airworthiness call issued on the RR Trent 900's early August.......and now there's an uncontained engine failure.......
As we push the envelope with new technologies, materials and construction methods, one line of thought is that instances of this sort of "design flaw" or "material failure" leading to component failure will keep pace with the advances.
Neither is particularly good news - we're either pushing the material beyond it's capabilities, or somebody in a room somewhere just thought "it doesn't matter that much".
I think the interesting questions, asisde from "What the hell happened?" is, assuming it is a design flaw, why wasn't it picked up in the rigorous testing? And if it was, why was it ignored?
If God had really intended men to fly, he'd make it easier to get to the airport.

I bet every engine in service has some form of AD, it is actually a good sign - people are catching and reacting to potential problems. There's nothing new about turbine engines developing problems in service - CF6, JT9D, earlier Trents all went on to be fine engines once fixes were identified.
