Do the manufacturers who build airplanes use their own "black boxes" in the planes, or are there companies whose sole purpose is to develop black boxes?
For example, in 2010 in the Airblue Flight 202 incident, the black box had to be sent to Germany for data recovery:
He stated that the box would be examined by "foreign experts" in Germany or France as Pakistan does not possess the equipment to decode the flight recorders. He also stated that the process of extracting information may take six months to a year. The Pakistani authorities decided to send the CVR and FDR to the Bureau d'Enquêtes et d'Analyses pour la Sécurité de l'Aviation Civile (BEA) in France.
It is not clear who developed that black box. Was it the same company that manufactured the airplane?
Also, can the buying airline use their own black box or their own security protocols for data encryption or encoding, to avoid having to send the black box out for analysis?
There's seldom a reason for manufacturers to design and build their own black boxes. It's expensive to run a production line to design, build a test a few. It's just cheaper to get an agreement with a company to make them for you. The second photo below shows a popular recurring model from Honeywell, which appears to have been used on the A330, B737 and B777.
Opening the black box can be a sensitive operation, especially if there's the fear that the chips might have been damaged. It's better to send it to somebody who's done it before rather than trying to master it on the first attempt, especially if you don't have the resources. Airplanes accidents don't happen very often.
Note that the case you're referring to, the Aircraft also appears to have been built by Airbus in Hamburg, and hence the German Accident Board automatically gets involved as well, much like how the NTSB gets involved in all Boeing crashes.

Another reason for this is if there might be political motives behind the crash, it's preferred to send it to a third party for analysis which is less susceptible to bias or interference.
If I gather correctly, data on the flight data recorder won't be encrypted at all- it will be fed out as serial data, but you will need the devices and software to understand this information, and if the outside connection is broken, you'll need to work your way to the chips themselves.

Furthermore, sending it to the company is not always a good idea- they might have motives to change the truth, especially if it was caused by dodgy maintenance or bad training, nor to the manufacturer, if it was production error. The accident investigation board is the best people for this matter.

Why is it that black boxes don't float? From what I gather the answer is: So they will not float away from a water crash site. The ping can be heard underwater with sonar. Finding the ping, finds the site. But why not have two black boxes one that floats and one that stays with the aircraft? That way if a plane is lost at sea, if we find the black box floating, we could use the data to find the other black box and the crash site. Plus the benefits of having a redundancy are enormous.
I never knew much about airplanes before the tragic incident of Malaysia 370. I have been spending a lot of time on Twitter reading various articles and investigations; in one of the articles I read, they stated that unlike transponders, "black boxes" cannot be turned off. However, each ELT is specifically designed for each aircraft, so it cannot be tampered with. You also cannot turn off the black box, as it runs throughout the flight, recording every 30 to 60 seconds. Is it really impossible to turn off the black boxes from within the plane?
Fleet, which is taking part in the search, said he expected the plane's flight recorders to be floating in the water. He said the recorders, also known as "black boxes", are fitted with radio... that radio beacon. We have not yet picked up anything, but that's typically what those black boxes contain." I was under the (potentially incorrect) impression that flight recorders, by nature..., the writer of the article, or I (or some combination thereof) misunderstand something about flight recorders and their behavior in water. My questions are these: Do flight recorders float on water
. This is just so we can find plane crashes in the sea when we don't know precisely where they went down (and to get basic data when the black boxes are too deep to get to immediately). Malaysian flight 370 and Air France Flight 447 would have both been greatly aided if these floaties were in those planes. What do you think? ...Without getting into the mess of redesigning existing Flight Data Recorders, I have a simple proposal that I think would help in deep water crashes. I propose that several floating cushion sets
Another enthusiast question. I watch a lot of the National Geographic Channel's "Air Crash Investigation", for better or worse, and it seems accident investigators make tremendous use of the Cockpit Voice Recorder "CVR" and Flight Data Recorder "FDR" to determine the chain of events leading up to- or the root cause of an accident. One of the more recent episodes of ACI (Season 12 Ep. 13... technology for maintenance data (and I think I recall hearing Boeing does too), I was wondering if either Airbus, Boeing, or the FAA, plan to facilitate or mandate that the CVR and FDR record
Why do they call flight data recorders a "black box" if it's orange in color? Just curious about this since I've seen several images of black boxes but they all come in orange colors, and not black. I can understand orange being used to help brightly identify the box , but then why call it a "black" box?
As I understand, there are two black boxes on-board an aircraft. One black box, the Cockpit Voice Recorder holds the cockpit conversations and the other, the Flight Data Recorder holds essential flight parameters. But why are the two black boxes holding separate data? Why don't both black boxes hold copies of both the FDR and the CVR data for extra redundancy in case the other box goes missing or is completely damaged by the crash? Are there any technical reasons for why this isn't possible or hasn't been attempted yet? Is there any benefit of having the CVR and FDR in separate boxes?
There are various services that use world-wide Boeing Winds for forecast wind data which can be used to calculate an approximate flight time between two locations. They usually have best case, worst case, and average case for each location, altitude, and date in the future. I have searched and searched Google to no avail. Where can this wind data be found, and how can it be used in a commercial product? For those of you who don't know what the Boeing winds are, I found this description of their software product on am informal message board (not related to Boeing): PC WindTemp
I recently had the opportunity to fly a PAR approach into Büchel Airbase in Germany. It was a ton of fun and I'll definitely try it again when I get the chance. However, as we were getting set up... heading. He didn't complain, but I'm still not sure if that's what he wanted. A bit later I got a similar call (callsign) request QNE However, I was unfamiliar with that Q-code (as a private pilot in Europe you pretty much need to know QNH, QFE, QDM and QTE) and only later found out it means "pressure altitude". Q-codes suck. Anyway I said "Say again" and he came back and asked how many were
