Help related fight data recorder

[lord8055]

I have a few questions related to the Flight Data recorder . As I see here is all about helping each other . I would like to get your advice.

As I have been working on a project related to the flight data recorder, I would like to know if you could help me get some detailed information about

this, for example, how the FDR works (not general information which is on Wikipedia and all , I want detailed information, for example, how

it processes the data), how and what types of blocks are used. For example, several printed circuit boards are used, how and why they are

used, what interface is used, how is the circuitry designed , what type of electronic elements are used and how they work , design of the

FDR , how the integrated circuit is built , the design of the FDR , etc. etc. I think you'll get an idea of what type of information I need, because I want to do my specialist in the department and study of the FDR, so I need to know, and I thought that an engineer or technical expert or anyone who can help me and share knowledge will be really helpful.

what to ask them , they hardly or almost never reply

do they have any jobs ?

out of interest, what attracts you to this specific piece of equipment ? I doubt that there are people who only design FDRs.

another day in paradise, or is paradise one day closer ?

this equipment is the most imp. part of the plane, in case of accident or any issue FDR is the first part they search for , and it makes me excited and i look discovering and exploring and working on it . so that's why I wanted to know if there are people who really focus and build the FDR , so I can ask them and they can guide me and help me understand what extra education i need

Bear in mind that there are probably no more than about 50,000 planes that carry FDRs, and roughly 600 new planes sold annually. Only minimal changes would be made in any short time frame; I would not see this as a booming employment environment.

TTFN (ta ta for now)
I can do absolutely anything. I'm an expert!

thx, I know what an FDR is. Remember too the CVR which is often as important as the FDR in deconstructing an accident.

Yes, I know there are specific design conditions to be met, I still doubt that there's a guy whose (only) job is to design FDRs. I suspect that it is considered "just" another piece of equipment, to be updated as time goes by.

Note too, there is a move to replace the FDR with ground stored data, systems I've seen called Inflight Safety Management Systems which send the FDR data over satellite comms to the home maintenance base, so the data is not lost. But so far I haven't heard of CVR data being stored "off-ship" ... union issues or pilot privacy issues I suspect.

what are the job aspects . if i want to work in field of FDR ?

If the companies that make them don't have job openings then it's probably poor job prospects. I think most of them make other avionic components - Flight Director/Flight Computers/Autopilot/Instrument panel systems. I expect before getting onto an FDR team you would have had a decade or more with systems that are not expected to survive a crash.
