yet, but that s the warning sign that one could happen, brianna. and that s how they analyze these circumstances where it s all happening very, very quickly. certainly too close. you can see it when you put it that way, tom. what happens if two planes get inteach other s space and the tower just for some reason doesn t notice, doesn t warn them? then what? well, interestingly enough, there is a system for that. let s say this happens. they re getting into each other s space and they re getting deeper into each other s space, that s when this kicks in. for some years now, congress has mandated that commercial jet line betters outfitted with something called the traffic collision avoidance system, or tcas. basically, what that means is there are computers on board watching out for this. and if the computer on within plane sees another plane in its space, it will warn the pilot. it will say hey, somebody is getting inside your disc, inside your plane s personal space. and if it keeps
and inform my mother that my father s plane had crashed. and i told him that couldn t be true, because he was the best pilot. the outgrowth of it was a very strong commitment by piedmont airlines to be involved in to the traffic collision avoidance system, and some years later they were one of the first frk, if not the first, airlines to fly with an active tcas system on board. six years later, betty barrett is on board a charter jet when it collides with a dc-9 over france. all 68 on the dc-9 perish. everyone on betty s plane survives. my father was sitting in the aisle seat, and i was sitting on the right-hand side, and i turned around and he s very british and very stoic, and i said, daddy, do you think we re going to make it? and he said, i rather doubt it, darling, and pointed to the other wing. somebody sent me this picture of when we landed.
software malfunctions in the past? could this have sent the plane to stall and plummet on this flight? bill? i m unclear about your question. but the airplane is very stable aircraft. and very easily controllable by experienced and trained pilots. so they just don t fall out of the sky. they just don t fall out of the sky. have something here we have to get to before the top of the hour. someone says, a pilot, the same pilot says, i say good night all the time, and i say good morning. he said, if the ttcas was turned off you wouldn t know if an airplane was near you. commercial planes do not have radar that picks up airplanes. the only radar is for weather detection and tcas traffic collision avoidance system. i said, can a plane shadow another at that altitude? he says the military does it all the time for refueling. yes, under the most perfect conditions. you re talking about two civilian aircraft shadowing each
all commonly, inaccurately, refer to as the black box. i know you re an expert on that mike, let me bring you in here first. what about what do you think? take nothing account here, you have a play a i know flight isn t the right word, but the track of where this flight was going to go was reprogrammed, the data we communicate to ground traffic chrome was turned off, the plane turns and appears to head into the middle of no where. yeah. some of the place on earth where there is no radar. let s rewind and look at some of the ways we can actually tract jet through the air. the first one is primary radar. primary radar sends out effectively a pulse, bounces across the fuselage and comes back it is primitive. and the secondary radar works with the transponder, absolutely key, the transponder gives you position, gives you altitude, gives you speed and what the t cast works off, the traffic collision avoidance system. does have limitation. on transo oceanic flight this transponder
pilot. the outgrowth of it was a very strong commitment by piedmont airlines to get that traffic collision avoidance system. they were one of the first if not the first to fly with an active system on board. six years later, betty barrett is on a charter jet when it collides with a d.c.-9 over france. all 68 perish. everyone on betty s plane survives. my father was sitting in the aisle seat, i was sitting on the right-hand side, and i turned around and he s very british, very stoic, i said daddy, do you think we re going to make it, he said i rather doubt it, darling, and pointed to the other wing. somebody sent me this picture when we landed, as you can see the tires are blown out, this is the broken wing, you can see all of this.
