Air India Crash

Absolutely, seeing what has happened is probably relatively easy - why, not so much so. If (and it's still a big if) they go down to route of looking at a software fault, I imagine they would then try to replicate it in simulator set up with the exact same software and hardware as the accident aircraft. Or possibly just on a bench with the relevant units - I'm not sure.

I think the CVR and FDR are combined on the 787 into one box. But I'm not sure if the 787 has one or two. According to press reports they've recovered two. But I think there maybe some confusion around this.

This reminds me of Jimmy de Ville, the presenter on a Quest TV motoring show, who used a KTM motorbike engine for a microlight, and flew it in the Alps. The engine cut out because the carb iced up, and he crash landed.

Hopefully the software state of the boxes has been recorded correctly during maintenance too.

Rather than cold fuel, the latest possible cause I had heard on a pilots YT video was vapor lock. I don't know enough about modern jet engines to know if that's the stuff of fairytale or not!

This accident does make you think maybe a cutting free of buildings should be in front and behind of runways for a few miles where possible. I know that's rather idealised thinking, but maybe for future planning.
On the 787, FDR and CVR are combined into one unit, called an EAFR (Enhanced Airborne Flight Recorders). There are 2 EAFRs on a 787, so essentially there are 2x FDR and 2x CVR. I read on a few news outlets that both were confirmed found and retrieved.

26 of their 33 787s have passed the additional checks mandated as well, interesting they are also checking 777s.

Not really possible, as you'd need something like 2-4 miles in most instance, at both ends of every runway (that gives maybe 2 minutes after take-off of clear space), and even then you'd not actually have anywhere for the aircraft to put down if it had a failure at say 90 seconds into flight as it would need to lose height then have the space remaining to land on suitable land.
That would rule out most of the worlds major airports, as it's already hard enough to find the space to put a modern runway as they can be 2.5 miles long (for say heathrow). Effectively you'd be looking at a clear area of about 10 miles in the direction of any runway taking large jets (the runway itself, plus your margin of error at both ends).
The reality is that this particular kind of crash is exceptionally rare.

Some have one, some have multiple, it depends on the model
Not just the black boxes that could be recording evidence either.

According to Sky News the recorders were too damaged by fire to be analysed in India, and the decision as the where they'll be taken hasn’t been made yet.
Also, the right engine was newly installed in March this year.

Air India suspends some long-haul flights after fatal crash and reduces the frequency of others
The airline's chairman has insisted the Boeing 787-8 aircraft travelling from Ahmedabad to Gatwick had a "clean history".
Saw that this morning and thought what have they found that has made them make that decision.According to Sky News the recorders were too damaged by fire to be analysed in India, and the decision as the where they'll be taken hasn’t been made yet.

They’ve found they’re damaged and the last thing you want to do is attempt retrieving the data without the proper equipment and risk losing it. You may only get one attempt at it.

Where to send them is a fine balancing act of expertise location and political dramas IIRC from previous accidents investigations.

I'd always assumed they would analysed in the US as they have far more expertise in this. And I would think they would be more likely to be completely impartial (although unfortunately, given the wider political environment in the US who knows)

Agreed - I am surprised it’s taken this long for that decision to be made though, given the implications of the outcome to all parties involved.
787s have 2 enhanced data recorders, both record the same data and voice.
