[News] Air India flight AI171 Ahmedabad -> London Gatwick crashed

[peterward]

Is there still a CPL too?

When I worked af the CAA back at the turn of the century I was test manager for a new European air crew licensing system.

I created a PPL licence in my own name with a Concorde type rating !!!

Yes. PPL, CPL, ATPL

Technology still hasn't quite moved that far yet. SAT coms are on board most aircraft now, but they don't transmit aircraft Telemetry. That is sent via, what is effectively a mobile sim card after landing.

In theory all Telemetry could probably be done in real time by sat comms, they are expensive to use, so while I don't know the reason why they don't, I'd guess the prohibitive costs of sat comms makes it not worth doing for all flights when only the odd one crashes?

But am I right in thinking that the engines do this, for RR at least?

 

[Scappa]

There are two different 787 engine suppliers, GE and Rolls Royce. You’d have to know which this plane used, which I expect they do.


If you look at the video @Chicken Run posted that shows the “pure” video with the RAT deployed.

Air India only ordered 787s with General Electric engines.

Not sure it can be that prohibitive when passengers can buy a video streaming package on long-haul flights for about £20 on most airlines nowadays.

It would have saved all that speculation following the Malaysian flight loss.

No technical reason why the data can't be transmitted securely in real time.

This. As somebody said up top, it's probably a cost/benefit thing. They could probably even transmit it directly to flightradar24 if they could monetise it

Rolls Royce can breathe a sigh of relief then.

For anyone interested in aviation whether through an accident, incident or just generally, that's a very interesting website. I learned what Cilla Black was like to fly with among other things from there.

My Grandad used to be Cabin Crew and I seem to remember he said to me when I was younger what an awful woman she was.

Yep l've heard that rumour too.

Her bad behaviour was legendary.

My mate was her hairdresser, he said he really hated her, she was f***ing rude but he did get a lot of work due to her fame.

Who could have predicted that a thread about a plane crash would veer off towards the behaviour of Cilla Black?

I must say it's a great surprise, surprise.

I’m as big a piss taker and wind up merchant as anyone on here, but surely there’s already a thread to slag off overrated celebrities.
May I suggest we stay on track here.

Understand the sentiment, I don't know the exact reason's why they don't do it, im guessing myself...... but Id suggest the way you see costs is not the same as penny pinching airline accountants who make those decisions!

£20 to stream all you want, that really doesn't sound much for sure, but if you took just 1 we'll known airline like Ryanair, who dont have Sat coms, they would need to install it on all aircraft............ plus they have never had a Hull loss or needed black box data, (they still do transmit all Telemetry data on the ground after every sector at cheap pennies costs on 3g/4g contract).

Even if Ryanair were to retrofit sat com systems, and if the Sat com user cost to stream Telemetry live was half of your BA/Virgin £20 passenger fee to stream Downton Abbey! at just £10 per sector, Ryanairs 3600 daily sectors at £10 each sector x 364 days a year is now just shy of 13 million quid a year........ 13 million to transmit data live for an airline with free black boxes installed onboard, that transmits all data retrospectively after every landing for pennies via 4g and have never had a crash.

Accountants wouldnt pay for it unless it's mandatory.

You don't need live Telemetry of systems, you do need to know where your aircraft is and since that incident, international rules changed and all operators are required to know exactly where all aircraft are globally at max interval of every 15 minutes. In Europe there's something called Global Beacon which uses flightawares ADS-B (same as flight radar 24) so airlines can track all aircraft via satellite/GPS live.... in theory..... No more Lord Lucan flights?

Not all aircraft have means to transmit live.

As I posted a while back I know we had basic data sent prior to landing of our B747-400 fleet I worked on the ramp and also station relief in America on occasions. For the life of me I can't remember the system but it was sent about 1 hour before landing so was probably 2g back then.
