I'm impressed about the picture quality. Couldn't find any info on the photographer and why he was there... I'm also quite impressed of the physics involved, I would've wagered that the plane would sliced right through the lines of the 'shute.

Most skydive companies take picture and video to sell to the jumpers. The wing of a Cessna like that is quite round and blunt, they also move very slowly during takeoff and landing (in the realm of 40-60mph). It's a testament to the strength of parachute lines as well.

Job Truniht posted:A plane just doesn't slam into the water ten seconds later from flying at 30000 feet. Even in that infamous Air Alaska horizontal stabilizer jam incident, the pilots managed to recover the plane at least once before it took a dip. That's why a bomb and/or structural failure are highly likely.

cstang posted:Seems like part of the mystery is over. A Vietnamese plane spotted what they believe to be a part of a door and a part of the tail. http://online.wsj.com/news/articles..._LEFTTopStories How strong is the signal given off from the black boxes? Would the search teams have to be directly over their final resting place to pick up on the signal? The flight recorders I've seen have ultrasound beacons for location underwater - and they're only so loud, which was part of the problem with the Air France aircraft - the water was too deep to hear them. They're a small metal cylinder in brackets at one end of the recorder, and it is possible for them to be damaged enough to separate from the main body of the recorder. The recorders themselves don't have any other location mechanism, but the plane should be fitted with an emergency location transmitter of some kind. The ones I know of are satellite-based and should work everywhere. However, they can fail or not be set off for various reasons, and could have been damaged during any incident. EDIT: Also, in case you didn't know - despite the common name, they're generally bright fluorescent orange. The name refers to function rather than form!

The emergency locator won't work if it's underwater, however. I'm not familiar with the ones used on aircrafts, but I assume they'd float, assuming they broke free of the fuselage. The ones used on ships are designed to float free of the ship when it sinks (There's a pressure-activated release) but even then they don't always float away for a number of reasons... And they're usually strapped to a railing outside the bridge, not inside the hull.

Aircraft ELT units are (hopefully) automatically activated by a G-sensing switch, and they will also float if they happen to find their way out of the fuselage. They also have a manual switch, so if you go down somewhat safely in the middle of nowhere, you can just grab the box and turn it on. If you have a Cobham ELT96/ELT97 from the early production runs, you can also count on them spontaneously activating themselves for no real good reason. The SARSAT guys and I have spent a lot of quality time on the phone together.

Are cockpit voice recorders/data recorders constantly recording or are they cleared by maintenance after the aircraft is turned around? I'm currently learning on a King Air (TC-12), and I know one of the landing gear squat switches (weight on wheels switch) has the function of "clearing cockpit data recorder." Does that mean it auto clears with weight on wheels, or is the function to clear it available with weight on wheels? Because that brings up another question, is someone clearing it during every maintenace turn, or is the thing clearing on every touch and go we do? And also, what kind of memory do those things have? I can't imagine it has too much, or that its digital even, since the airframes we are flying on are late 70's production. Has the tech in these recorders changed much?

Bob A Feet posted:Are cockpit voice recorders/data recorders constantly recording or are they cleared by maintenance after the aircraft is turned around? As of now, CVR's are required to record for at least two hours per the FAA, and automatically begin overwriting the oldest recording once that time elapses. Flight data recorders must record at least 25 hours, and also automatically overwrite old data as needed. As for the recording medium, that depends on how old the recorder is. Older recorders used magnetic tape, which was relatively fragile and prone to degradation over time and mechanical issues that could keep it from recording properly. Since the 1990's, there has been a switch to solid state recorders, which are more durable and reliable than tape-based units, in addition to requiring almost no maintenance and being able to record more data than tape could.

It looks like he went fancy with a spring and washer instead.

Ok some info regarding flight data (FDR/DFDF) and voice recorders (CVR) , and emergency locator transmitters (ELTs)  too, why not.Most aircraft are fitted with a separate CVR and DFDR located somewhere in the rear of the aircraft. Pretty much anything relatively modern is going to have a digital flight data recorder, and the CVR is probably going to be digital too, though depending on what the airline has in its spares pool there may be some old tape units floating around. Some aircraft, (Embraer 175/190, B787, B777*) have an integrated CVR/DFDR system that has both a forward and aft unit recording duplicate information. In both instances they will record flight data on a 25 hour loop, and voice/datalink transmissions on a 2 hour loop. Generally you're going to have 4 voice channels (capt, f/o, observer, and area mic), and a minimum of 88 flight data parameters (on a modern system, probably more) being recorded. Once all aircraft power is lost, you're going to lose your flight data as well, but in the case of the integrated systems, one location will have a redundant power supply and will continue to record voice for as long as its battery lasts. If you're interested, the standards for impact survivability are 3400g for 6.5ms (approx 270kts and 450cm of crushing distance). There's also standards for deep sea pressure, fire, temperature, etc. Speaking of sea pressure, that cylinder on the front of them is the the Underwater Acoustic Beacon. It will buzz at 37.5kHz for a minimum of 30 days at 150db once it's immersed in water, up to a depth of 20000ft. You'd find it with hydrophones. Incidentally, they're mounted to the crash survivable chassis of the unit, not the external case, so they shouldn't come detached at anything within the range of survivability of the chassis itself. ELTs work on impact, and as noted won't work underwater. The aircraft mounted ones would presume a very hard landing but mostly intact aircraft. I think they trigger at something like 6g of lateral force. If the aircraft rips apart in the air, they may not be much use. The portable ones are again for emergency, not catastrophe. If you belly land on the ocean and jump into the rafts, you'd grab one and chuck it in the water (holding onto it's string...), the water activates the battery and transmitter and it'll float along behind you. ELTs are monitored over line of sight radio (VHF, UHF), and satellite. * The 777 has a traditional setup of separate DFDR and CVR located at the rear of the aircraft.

While there is a lot of speculation about cause and how something big can simply vanish, here is a previous accident which is similar in many ways: http://en.wikipedia.org/wiki/Adam_Air_Flight_574 Disappeared with no mayday, no trace of the wreckage was found for a week and in the end, the cause was incredibly stupid and trivial.
