EgyptAir flight from Paris to Cairo missing

Yeah I've just gone back a few pages. Thanks.

Why would the ACARS message use L and R for left and right instead of port and starboard? Not that R would mean 'rear' either because that would be aft.

Black box technology is a fantastic example of human engineering yet they haven't found an easier way to find/recover it. Really think this needs to be improved.

They haven't found a way to solve lost socks yet either

Caged and AHarvey,

Thanks for your replies. We will be in touch shortly.

Hello, This is the daily mail calling...........hello.......hello

Amazed they don't have autofloatation devices and transponders attached.

If you mean an air pressure vessel that could inflate a balloon etc.. I don't think that would be very safe. The amount of air that would need to be stored and the amount of pressure could cause an accident should it fail.

What - like the inflatable rafts? The balloon is actually a really good idea!!

Compressed air in a confined space is never a good idea.

What I meant was aircraft already store compressed air to inflate slides/rafts, then there's all the life vests. Or am I missing something? (not intended as sarcasm).

Those items aren't where critical systems are located - unlike the black box which generally is. I guess there's the potential of relocating the thing.

How much does a black box weigh? I'm guessing it's something which was designed years ago and barely updated. The actual components could be grams and surely with today's tech even the casing could be pretty lightweight?

My point being that it wouldn't then take much to make it float.

From what I recall they're foam filled any way. The problem is getting them clear of any structure they're encased in. You don't want them loose and rattling around.

They would take an awful amount of air to fill a balloon able to float them. And a balloon with enough air to float something from the bottom of the ocean would most likely burst half way to the surface and the FDR would sink again

The actual components of a black box don't weigh much. It's basically just a drive to record data. What makes it heavy is all the reinforcement it needs to withstand a 300mph crash, gforce and explosion

Doubt you could make it super lightweight and still able to withstand a big crash.

Graphene honeycomb structure ?

 

[insane200]

With planes starting to have WiFi on board, why cant they implement a system where the flight recorder syncs the info to a cloud based server as well as the black box.

 

[Caged]

They can, and do. It costs money though.

It also has iffy reliability!

Of course, but for when instances like this, they would have immediate information to what happened, maybe even advanced info and could pre warn of a incident on board.

iffy is better than the possibility of not finding the Flight recorder though.

What about steel cylinder holted to the side, water detector, large automatically chemically inflated airbag

Doesnt matter how heavy it is even a fairly small airbag will make it float
