I bet the plane crashed from mechanical failure before the terrorists could put their plan into motion. No such thing as partial credit in the world of suicide bombings!

rocket_man38 posted:Can someone correct me if I'm wrong, but don't the radio systems have their own power in case of an emergency? There are redundancies in virtually every avionic, hydraulic, and electromechanical system on a modern airliner. In event of main generator loss, large aircraft such as these are typically equipped with ram-air turbines which can be extended into the airstream and provide juice for the critical systems. However, auxiliary power won't matter if your aircraft has the tail fall off, or a primary fuel tank explode. Catastrophic failure of the severity we are likely seeing here leave no time for the crew to attempt to save the aircraft.

Rad Russian posted:Sudden course change and a long straight flight does coincide with a theory of being intercepted by a fighter jet and then being forced to be "escorted" in a different direction. If there was a mechanical failure and they were simply turning back, they would go back towards the airport not in a random direction. They covered enough distance after the turn to make it back to their starting point if they actually wanted to. You don't know what you're talking about.

Emanuel Collective posted:When a plane is at cruising altitude it takes a special level of incompetence to crash a plane sans instruments, barring some mechanical failure. Your only task at cruising altitude is 'keep the plane from stalling' which doesn't require any instruments. Landing could be a problem. It's actually remarkably easy to lose your situational awareness when flying without instruments at night, or in any sort of bad weather. When you can't see the horizon all that well, you begin to lose your situational awareness. You can enter a dive or a climb and not notice. You might even begin to think that you're entering a turn or an inversion and make corrective moves for no reason. These phenomenon are not unheard of, in fact they result in crashes of small aircraft and military flights every year.

Awesome! posted:We hear all about how modern planes have layers and layers of redundancies for safety systems but it seems like this pitot tube thing failing basically bypasses everything since it's a support system common to lots of the avionics. Isn't that dumb? Is there literally no better or more redundant way to accomplish what this pitot tube does? Pitot tubes are generally very simple and accurate sensors for airspeed, air pressure (used to calculate altitude ASL, above sea level), and angle of attack (your level of pitch relative to the horizon). They're a metal tube or blade, attached to a simple electrical or pneumatic circuit, which drives an instrument in the cockpit, or interfaces with a computer which turns the signal into digital data. In almost every case, the tube is also connected to a heating element which keeps it warm, since the outside air at high altitudes is below freezing. Being analog systems, in a modern jet airliner they're already capable of being the main backup sensors for the instruments in case the GPS or FCS stops working for another reason. The whole reason pitot tube freezing is a big deal is because in older aircraft the instruments will no longer function as intended, and in newer aircraft, the flight control computers will be receiving insufficient data, which can cause the autopilot to get wonky or disengage. In a daytime, clear weather context, this isn't such a big deal, but at night or in clouds, even just a few minutes' worth of confusion can cause a crash.

XK posted:Do inertial systems have too much drift to be usable as a backup? Inertial navigation units are essential equipment on an aircraft, especially fly-by-wire aircraft. However, they only tell you where your aircraft has been and is going, relative to a starting coordinate. They can't tell you your relative airspeed, or your current altitude above sea level. They can tell you a lot of things that pitot tubes cannot, but the two systems complement each other. gradenko_2000 posted:I think there are alternative ways to derive relevant flight information such as a radar altimeter or ground control radar (assuming you're in range, which AF 447 wasn't AFAIK), but that requires training the pilots to recognize that their instrumentation can't be trusted and that they need to use this other form of instrumentation that might be as well integrated nor as instantly responsive as the altimeter that's staring you in the face. Radar altimeters are excellent, but only at low altitudes. On the aircraft I used to work on, radar altimeters were only useful below a few thousand feet, basically a fraction of the cruising altitude most airliners are flying at. They're essential for safe landings, or flying low over terrain features, but for flying at heights, they're useless. Using ground radar for these measurements is also situational at best. Aircraft which have instrument failures over busy air corridors like the US or Western Europe have used such methods before. It would require triangulation, and as you say, where they were flying it would be improbable. I remember reading somewhere, Air&Space Magazine perhaps, that the next big innovation coming down in technology was going to be "smart skin," basically covering most of the aircraft in conformal sensors that could measure external conditions at specific parts of the airframe. Maybe we'll someday see those replace pitot tubes; the only problem I can see is that they're digital, and you'd still need an analog backup for emergencies, so pitot tubes would probably still stick around as an emergency sensor.

Awesome! posted:seriouspost: can they line the cockpit with Pilots accomplish the same thing through referencing their artificial horizon, and their turn coordinator. These two instruments are driven by gimbals or gyros and can usually function on only emergency power, but in a glass cockpit such as the 777, the main versions of these instruments will be digitally displayed and receive their data from the computer.

I've been on the open ocean and seen pretty bright meteroites before. It could also be that the guy is making poo poo up. The only way to find out for sure is to find the drat plane, and I think at this point the seachers are just leaving no stone unturned.

hofnar posted:That works just as well at 35,000 or even high 20's for that matter. My guess for whatever it's worth is the altitude deviations were a result of a struggle up front. I'd normally throw this theory right out the window with it being a  POST 9/11 WORLD what with sealed cockpit doors and all, but that story about the co-pilot inviting total strangers up front because he thought they might bang him makes this depressingly plausible.

If the US military has radar of practically the whole Indian Ocean (which I assume you would want if you're hosting a secret Naval base there), why aren't they sharing it or even talking about it?

Big Beef City posted:The thing that gets me, is that it has been postulated that the plane was diverted and flown somewhere "for future use". You could hide it in a hangar; a big one that is also at an abandoned airfield might be hard to come across, but camo netting could obscure it from the air. Then when you fly it out you use a transponder code for a known flight on your route and hope the confusion lasts long enough to complete your objective.

CottonWolf posted:'Tell us this stuff you don't know, or we'll kill ourselves?' That sounds a little counter-productive. Societies without complete media freedoms do sometimes exhibit a willingness to accept conspiracy theory as truth simply because the government hides so much information all the time. I think you're right though, nobody knows for sure quite yet so this is unproductive.
