But the battery of the black box pinger expected to last some 30 days, and this plane has already been missing for 28. natalie? >> and, of course, finding it will help solve this mystery of what in the world happened. and the other thing that were hearing about, erin, is the investigation that continues into the chief pilots personal flight simulator. what do you know about that? >> thats right, cnn learning new details about the contents of the hard drive of the flight simulator belonging to ma...

>> i imagine that there is a lot of noise in the ocean. im wondering what other natural sounds could be confused for the pinger. >> there are a couple different types of sounds in the ocean, tectonic sounds, whale sounds, that kind of thing. but the processor is able to distinguish the sound the pinger makes. >> this is a tweet from james. if the pinger locater gets a hit, how long does it take to deploy the rest of the technology needed to find flight 370? one australian scientist who developed...

Lumpur. nic, thank you very much. lets talk about this with mary schiavo. >> and also simon joining us from southampton, england. simon i want to start with you, four weeks into this flight, were you able to hear what the acting transportation minister said this morning? and if so, what did you take from that news conference? >> i did. i mean, the first thing to say is that the 30-day battery life of these pingers, just about the talk of the deadline, it took a lot longer. we know that these thi...

Flight 370. but time is running out for the pingers battery life. >> what theyre trying to do is get ears in the water while the pinger is still going. >> reporter: this is the sound its listening for. the towed pinger locater, or tpl, is 30 inches long and weighs just 70 pounds. its towed behind the ship that operates it, in this case the ocean shield, and generally moves at about 3 knots. that means with 150 miles or so to cover, just a sliver of the search area, it will take days. >> it does ...

Not just necessarily one, since both flight recorders are equipped with pingers? >> theyre both -- both recorders are equipped with a unique pinger but the pinger is on the same frequency, so the 37.5 kilohertz is identical to both pingers. if you hear one and the other one is adjacent or nearby, youre going to hear a second ping. it wont be synchronized. the units dont talk to each other, so you will hear two independent pings at that same frequency and same pulse rate. >> and according to the ...

All. theres some question as to whether the batteries were properly serviced. you need to be in very close proximity. so at the depth where presumably this plane might lie in the indian ocean, that wouldnt seem to be the most effective means of finding it. >> i would think not. usually the process goes first stage is use the radar and gps data off the plane if you have it. and also look for debris, which they are doing. and then you hind cast on the debris. then you go into phase two which you m...

Continue listening. you know, you have to wonder -- its interesting a chinese ship that is usually not ideally suited for doing this found or heard this pinging noise. did they have satellite information they werent necessarily sharing with everybody else or some sort of data that came through military means that put them on this site? otherwise its incredible shot in the dark and, you know, could be potentially the break everybody has been waiting for here. i will put myself in the cautiously o...

I guess the pinging at some points, right? do you think even though it wasnt continuous it could still match the description of a pinger? >> by continuous it doesnt emit a constant tone or frequency. it is a pulse, it goes tick, tick, tick. but it would be a continuous series of ticks. now, it is an acoustic device. if they got out of range, if something happened to block that acoustic sound for a period of time while they were listening, that was possible as well. but again its a very repeatabl...

While ago that it could possibly tell us that it turned, bwe dont know who turned the flight, et cetera. but with some of those things off the table as an aviation securities analyst, what do you glean from what you can get? >> then well know what the airplane did for seven hours, and from that, we can attach other things to it, like what was going on on that airplane. remember, the parameters that that box monitors on an ongoing basis, so its a push in the right direction. but again, its not ne...

Cant reach the surface. its 4400 meters at that point. depth of water. so they cant physically hear that signal from the surface. number three, we dont know what equipment the chinese is using. they say 37.5 kilohertz. but thats -- it could be a wide band frequency, it could be anywhere between 40 and 70 frequency kilohertz. so there are a lot of questions that have to be answered. i would discount that. >> so, art, lets play some sound now of what this pulse or the pinger would sound like. you ...
