    Can an FDR on a Boeing 777 be interfered with or vandalised during flight?

    If this has happened on MH370 then the black boxes may not yield any data if found.

  • . 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...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 be distributed around the plane (tail section, along fuselage, etc.). These FDR floaties would be about the size of a seat cushion, but they'd be wrapped in a water soluble cover. When a plane crashes

  • 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) was about Air France 447, the worst disaster in French aviation history. That investigation spent two years and $50 million just locating the CVR and FDR which were ultimately found resting 4 kilometers... 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

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...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

  • 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?

  • A recent news item mentioned that "black boxes" are typically stored in the tail section of an aircraft to maximize their odds of surviving a catastrophic incident. If they're stored in the rear of the aircraft, presumably flight data and cockpit voice data is transmitted via wires which run the length of the aircraft. Aren't these susceptible to damage during an incident? There have been incidents of explosions and fires which damage flight control cables - aren't the FDR and CVR susceptible in the same way?

  • I'm from Brazil, and here we use the West/East rule, so we use an odd flight level when we fly between 0/360 - 179, and when we fly between 180 - 359 we fly in an even flight level. But what should you do in other countries? Where I can find those rules? I've heard that in Europe it's totally different, and that in some countries in Asia they use meters, instead of feet. Where can I find this information?

  • These days, when reading news about missing Malaysia Airlines Boeing 777-200, I keep coming across a scenario where pilot might have deliberately turned off the transponder which is used for the communication of flight with ATC. When there is a possibility that any bad thing can happen when pilot turn off transponder, why would one give the ability of turning off the transponder to a pilot when he/she usually depends on instructions from ATC or flight control. Is there anyway that ATC can turn on transponder back from ground?

  • The answer for How does wind affect the airspeed that I should fly for maximum range in an airplane? refer to a velocity/power-required curve. As far as I can tell, this curve can't be deduced from information in the flight manual. I suppose one could experiment and determine what power setting is required in order to maintain level flight at a bunch of airspeeds. (Or for a glider, record the sink rate, which is proportional to the negative of the power-required, at a bunch of airspeeds.) Would that be accurate enough? Are these curves available from the manufacturer?

  • I've noticed that on some airlines (I may have seen it on SAS) the cabin crew had a small touchscreen at the front of the plane which they were using to select recorded audio messages etc, in both their language, and English. Searching the internet, I found out it's called a Flight Attendant Panel — here are some photos I found: So I gather they can control the lighting, and movies; but what else can these panels do? I also found a FAP trainer, which says: This virtual training environment generates a realistic FAP representation including OBRM, CAM and PRAM What
