Been done. but the airline industry, as has been said, is under so much financial pressure. it needs -- it needs to be mandated by icao for the whole industry to move forward. >> arthur, one of the arguments against using live streaming data is too many planes transmitting too much information. do you buy that? >> i do not. and there's a very simple solution for it. instead of streaming all the information that's contained in a flight data recorder, you limit the stream to basic information like air speed, like altitude, like -- like ground speed, like position. and then if an airplane goes of...

>> [ inaudible question ] >> as a understand it, the speed has been determined on the basis of the pinks that happened over a period of time. we don't know what was happening between each one. we don't have any altitude data. >> [ inaudible question ] >> altitude this impacted the speed because i am getting very technical here but fundamentally, if you are at high altitude, your ground speed increases quite dramatically. if you come down to a low level,

Target. it has no data to it. it has no time. they had to then refine the time and when boeing looked at it and saw how fast the airplane had come back over the peninsula, that's when they refined the fuel calculations based on speed, plus, you have to worry about winds aloft, winds aloft will change ground speed and of course it will increase fuel burn if you have a head wind decreased fuel burn if you have a tail wind. all of that was recalculated to come up with this new search area based on a more refined data. but the key here was that the primary data because it has no absolute data info...

287 knots or we are going.84% of the speed of sound. this is the ground speed. in other words, how fast we are going, presumably over the ground which is 475 knots or close to 500 miles an hour according to the new data. this is a typical cruise speed. to slow us down slightly and yet extend and reduce the range of the search, we need to know so much more. the altitude and how long they now at the altitude and the head winds, so much more than the speed of the plane and which speed is it? the speed over the ground or in the air. richard, please. >> we don't know. all we know is from the ansa t...

At this stage, the location of the aircraft and the satellite were known, so it was possible to contemplate symptom characteristics for the aircraft satellite and the ground station. during the flight, the ground station logged the transmitter and received powers frequency at each handshake. knowing the system characteristics and position of the satellite, it was possible considering aircraft performance to determine where on each arc the calculated burst frequency offset fits best. the analysis showed poor correlation with the northern corridor but good correlation with the southern corridor....
