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.

I must admit I always thought they were just (very) rugged version of a USB stick / solid state drive which just wrote over the data held longest once it filled up.

Remember - More details = better answers
Also: If you get a response it's polite to respond to it.

the older versions, with mechanical recording, had more mechanism in them

Typical flash memory has a local controller that verifies the data is correctly written, keeps track of the number of times each area has been written, substitutes other areas when defects are found or redirects writes to less written areas (wear leveling). It is typically not possible from the outside of the flash controller to determine where the data is actually stored. On top of this will be the logical controller that pretends that the flash is contiguous and in sequence and takes the data requests and translates them to commands to the controller.

Not useful in an FDR, there have been fraudulent USB sticks that misreport actual data capacity. Some are smart enough to detect probes from anti-virus software and hide files that contain a virus.

In an FDR it would be useful for a logical controller to write data in parallel for data error detection to multiple flash controllers.

There are hobby FDRs for R/C airplanes and rocketry, but anyone asking for a beginner course is a year or more in learning programming and electronics debugging before building a useful one.

I wonder if there's a TSO for FDR compliance ? (no, I can't be bothered to look it up, but if someone knew …)

thx Will.

then it should tell you what you have to design to … loads, temps, times, etc.

of course, it won't tell How to design it ! But it is a typical certification standard.

WKTaylor, RB1957, IRStuff, 3DDave,
Are you all... I dunno... ...bored?
Why entertain this discussion when all of you know it's pointless and all of you know the OP is clueless?
Typing at 30 words per minute have you all collectively blown 1 hour on this thread?

"30 words per minute" ??? … geeze, lucky to break 10 !

what's the matter steve, you don't like windmills ?

SW...

New members with opening questions... like this one... can lead to interesting/unique discussions amongst ourselves... and light a fire under the newcomers who are truly interested/motivated to learn... or smoke-out the 1-timers who are amateurs/frauds/phishers.

I discovered... painfully... a long time ago that amateurs/frauds/phishers expose themselves by the content of their discussions... and/or 'topic-ignorance'... IE: obvious inexperience not interested in true-learning... and/or presenting a narrow/channeled focus that RARELY/NEVER crosses similar-to boundaries... and/or verbiage that may/may-not have a 'ring-tone' of authenticity... and/or may/may-not suggest/imply something illegal.

In the case of lord8055, my antenna are 'up' and I [we?] have suspicions RE background/motivation... although [lord8055 if listening] I sometimes have to be reminded by my wife to 'have patience and tolerance' for youth and inexperience.

BUT... again... this is an interesting and mostly unexplored topic-area... and I've actually 'learned something new' from some of the replies!

I really appreciate you people helping me and explaining me , some information really helpful , but some people really not helping and just saying negative stuff and demoralizing . i really want to learn, and understand . i want to do specialization and understand the whole FDR. if anyone of you can send some old FDR mechanism/ working in detail pdf. so i can read and understand . it would be really helpful.

I am studying on flight data recorder, but as you know it's just basic, and soon I will finish my master’s degree and enter professional working field. But you know I want to work as a Flight Data recorder Engineer, but I exactly don’t know how to process ahead, like which aspects and where its possible to work as a flight data recorder engineer. Plus, as you folks have so much experience and knowledge on this topic, can you tell me what extra
knowledge needs to be acquired and so I can also study and develop my knowledge on those extra fields which can help me in my professional
work life.

what is a "flight data engineer" ? ... a flight test engineer ? or an air accident investigator ?

you mentioned earlier that you wanted toe design/build an FDR. Why not buy a scrapped one and take it apart ?

I mean a flight data recorder engineer . A flight data recorder is not just one piece . It’s made up of several parts and several engineers are working on it . I want to know about what type of engineers are working and making the flight data recorder and if I want to work in the field of flight data recorder . Where can I work and as what type of engineer . If I want to develop or design
