Flight MS804

With high speed telemetry, it's usual to have two way communication "handshaking" to ensure that packets of data are transmitted reliably to base. It's not essential though.
I imagine that the BB technology is hopelessly outdated compared to technological advances in remote telemetry over the last 15 years, but that's just a wild guess.

Who'd have access to that data though? Manufacturer's or those who deal with the aftermath.

Given the route being flown, there's a fair few unknowns about its location in the the last half hour.

I wasn't speculating about any aspect of the current tragedy. I was just suggesting that high speed telemetry is probably capable of giving at least as much data as a "conventional" black box, and probably a lot more reliably and quickly. Given that it takes many, many years to develop a new large aircraft, it's hardly surprising that many aspects of the electronics are hopelessly outdated when the aircraft comes into service.

Edit: I think it would be reckless for the data to have to be made available via the manufacturer for obvious reasons.

I wasn't referring to recent events either, except for that last part. See edited post to see what I meant.

A beeumb surely?

No, you are misinterpreting that Excel data. It's what happened in the final couple of minutes of the flight (and which caused it to stop transmitting the data) that's unknown. The ADS-B data shows a perfectly normal flight profile right up to the point where the data stops.

Main locations of plane's wreckage identified
The main locations of wreckage from the EgyptAir jet that crashed in the eastern Mediterranean last month have been identified by a deep ocean search vessel, the Egyptian-led investigation committee says.

Key points:

• Investigators will now draw up a map of the wreckage locations
• It was not specified which parts of the plane had been identified
• Investigators are racing against the clock to find the black boxes which are expected to stop emitting signals on June 24

The John Lethbridge, a search boat contracted by the Egyptian Government, has provided the first images of wreckage to investigators.

Hopefully the ULB pings won't be needed if the main locations of the wreckage have now been found, one of which will presumably include the tail section, where the FDR and CVR are located.

 

[DaveReading]

Actually that's not correct. There are black box systems that can live stream (e.g. the FLYHTStream system from Flyht Aerospace Solutions) and some airlines are retrofitting them - Qatar Airways for example.

Notwithstanding what Al Baker has said, his promise made back in November that the media would "soon" be invited to a live demo of FDR data streaming doesn't seem to have happened yet.

There's no mention of FLYHT's website of Qatar as a customer, which may or may not be significant.

Glad to hear they have found the main wreck site.
I had always assumed the Med was a shallow sea. 3km is a long way down.

This is an odd one. No attempts to claim responsibility, no checks ordered by the manufacturer or investigation of the operators procedures publicised. It fell off the news pages really quickly and there has been a whole absence of speculation in the usual places.
I don't intend to open up speculation here, but the response to it hasn't followed the pattern of recent years.

[QUOTE 4325143, member: 45"]It fell off the radar with the press because there's nothing juicy about it. The manufacturers involved in the plane will have started investigating when it hit the water and won't have stopped.[/QUOTE]
Of course there is a a rigorous investigation, it's the lack of reporting and speculation that seems different this time.
