As above, the "key" to finding AF447 was re-evaluating the P of the "pingers" actually working / being heard. Contrary to the opinion of industry, the firm conducting the analysis downgraded this P,...

I think it fairly safe to assume nobody, including Inmarsat, quite understood the implications (or even presence of) the "pings" and the subsequent analysis. A scenario where somebody aimed to...

NB they are not searching where they think it crashed. They will search taking where they think it crashed, plus 20 days of appropriate drift. No idea of the details, but 1K of drift would now be...

Strictly the A321 did not end up in 1 piece, the lower aft fuselage was pretty much torn off.

However, I am not sure the question is whether it can be in "1 piece" or not. It is whether it will...

Not too sure about this I'm afraid. This accident has ensured any future plan will involve isolating the Satcom units themselves as well, not just the protocols that use it.

Chinese object is a 18 Mar image
Original objects are 16 Mar, and approx. 70NM NE of the latest Chinese position.

Surface drift I believe is a little North of East? i.e. wrong way.

Does not...

Sorry, but I disagree. The whole lesson of eventually finding AF447 was the "Bayesian" theory.

Each piece of information is evaluated, given a probability and move on from there. As with AF447,...

I would think it possible to disable ACARS without the pilot alongside knowing. There are plenty of Maint functions via the MCDU type boxes that some pilots know a lot about, some play with, others...

One reason could be they are looking for traffic coming into their area, not transiting / exiting.

Secondly, if there is any correlation between the civil and SSR side, the primary return could...

Yancey OK - we'll have to disagree ;) I have fair reason to believe that some 777s (and know from other ac types I fly / have flown) only have non ship powered ELTs, that are manually activated by...

Yancey Your link is as I say - it is required to have an ELT. That link does not specify "g activated" - just "fuselage mounted as far aft as possible" (to survive a crash). Older airliners have...

Can anyone confirm whether all airliners now have crash activated ELTs? Or whether just newer ones do, and the older ones...

I beg to disagree, but the upload system would surely have stopped at the same time as ADS-B / Transponder / ACARS etc.?

It depends on the nature of the failure of course, and/or how things were...
