angle of attack. the plane loses lift and can plummet. the reason the airplane flies is because you have high pressure underneath and low pressure on top. if this is the nose of the airplane and this is the relative wind the steeper the angle of tack occurs the more likely you ll get a stall. in the case of qz8501 already a possible critical piece of information. air traffic control data showing the ac 320 descending shortly before disappearing from radar. it seems an attempt is made, at least that s the evidence so far, not verified with data he was avoiding weather by going up. that s not something we normally like to do. we normally go left or right. as for 8501 air flans flight in 2009 was flying from rio to paris in a powerful storm. ice formed on the tubes that

boxes may explain what led to this disaster. but how will searchers look for the plane under water? first, they will likely listen for it. all commercial airplanes are required to carry pingers, underwater locater beacons attached to the black boxes. they emit a ping once a second. it s really simplified an under water microphone. this is the type of device they ll tow behind the vessel and listen for that pinger locater. how far can it hear? about five miles. unlike the extreme depths of nearly three miles in the indian ocean where flight 370 disappeared, the java only runs 80 to 100 feet deep. while it s easier to operate the hydro phones at this depth, he
