Bullshit!

The plane is probably broken in pieces and spread over a great aerial and they have to find the tail, where the black boxes are stored.

I'm tempted to give you bad karma for your lack of thinking, rather than comment on what you have said.
Do you have shares in the aviation industry. ?

Do it, no problem

I was speaking to an expat, who runs a certain bar in Kampot, who's background was in this stuff.
Apparently we is flying on windows 7 or earliest, with a whole lotta patching shit together, coz ' technology has changed and you can't get that part, that we designed the plane around, any more.'!
Dunno.

Search teams are using an underwater drone, as well as underwater "pinger locators", to try to pick up the sonar signals from the cockpit recorders.

Look on the front page of BBC World for: Lion Air crash: Indonesian plane search focuses on fuselage.

Here is the thing that I do not understand: my watch, my phone, my Ipad can locate me within a meter or two, but guys have to listen out for a ping from the black boxes? I mean I remember watching "Das Boot" where the Brits could locate a Kraut submarine. In 1940 something.....

Quit simple: The ping signal is very weak and there are no "ping telephone poles" on sea , so they have to search for the signal.
PS,
I rest my case in this topic

As these "Black Boxes" are so important after an aircraft accident I would have thought that they modern technology would have devised a easy locatable unit. "The ping signal is weak". WELL make it stronger......so you can locate it.

There isn’t a magical formula. It’s all science. Size vs. ability. If black boxes were built the size of airplanes, and maintained at every stop, then planes could be easily located if they went down and would last a long time.

But is the flying public willing to pay double or triple the price on tickets, a double mass plane means more fuel required, and willing to wait longer for flights? More maintenance means longer turnover times. All this extra cost for something that will probably never happen? Percentage of crashes vs. successful flights?

There are multiple black boxes stored in different locations on the plane recording different things.

A commercial black box is a compromise. Weight vs. size vs. reliability vs. ease of maintenance against something that rarely happens.

Whales are giant monsters that have huge low frequency sound generators. Would anyone pay for a whale sized black box?

There is the SOSSUS system for detecting submarines as they leave from Russia.

Sonar can’t detect objects hundreds of thousands of miles away lying at the bottom of the ocean.
