In very rugged terrain. we have news that we can tell you from reuters. and that is this it is being reported by the french interior minister that they have found at least one of the black boxes, make no mistake, they are orange. this is something they may have been able to spot from the sky as there is no reporting that anyone has been able to land. there has been some reporting that rescuers. reporter: at least recovery agents have been able to lower via cable from helicopters but no helicopters are landing but there is news that one of the flight reporters has been found, whether it is the flight data recorder or the cockpit voice recorder is unclear at this time. but one of those recorders has been found. whether it s been retrieved is also another issue as the weather is terribly inclement and terribly difficult for those on the ground to recover anything at this point given that they ve been lowered in. anyone who may be on the ground did not land.
May have been functioning properly because there have been questions about that in the past. there have been. pitot tubes are located you ll see them on planes as you get onboard. you can see them down here. that s what a pitot tube looks like. they are heated so they won t freeze over. when that happens, this measures how fast you are moving through the air. when that happens, the pilots are not so sure how fast they are moving and that can change many things. mary has been talking today about angle of attack. the truth is pilots have to rely on instrumentation to tell them if they are angled up or if they re angled down, what speed they re traveling. as mary noted, you get close to the mountains and you would think someone would be able to look and see it then. if they believe that they are well up above that until that critical moment, maybe they just don t know. all of that, i must say angle of attack, what it affects is
In the world and along with those is a lot of downward force and upward force. a basically big old heat cycle and heat engine. on the upward part you ll go for a ride up. the question that we do have to ask to be careful about we re look at radar data which comes from the trance responder. this is the secondary radar information and don t know how accurate that is necessarily. there could have been preliminaries with the instrumentation on the aircraft or could have been iced over pitot tubes but a static inlet which indicates the altitude which could have provided some bad data in this case. having said that that would be no surprise given the environmental conditions that this plane was flying into. but there are other aircraft flying in the vicinity as well. they managed to land safely. thunderstorms are incredibly dynamic and short-lived. what happens in one place five minutes later can be a complooltly different story so when people say, well another plane flew through there,
In the case of the air asia flight they formed in the morning. had much of the same effect. the danger lurking within these storms, pilots are very alert to are these extreme down and up currents so they can fly through each of those conditions successively and that cause very violent turbulence. as i said i think the difference here is that there s a lot of rain involved in this scenario which there wasn t in the south atlantic at the time. okay. we do know that air france flight though had some problems with icing and, in fact the air speed sensing probes became very clogged. pilots lost their speed readings. could that have happened here or was the a320 designed differently than the a-330. the speed reading instruments called pitot tubes are different or unimpacted those on the 330 have been changed. that s thenot the same. what we re looking at here if we
Inaccurate? absolutely. i mean the pitot tubes that we re referring to that send air speed information to the air data computers and send to the instrument panel if you have erroneous information you ll get erroneous warnings. things that won t make sense. that s why that air france 447 was an interesting accident in that regard. they were getting such conflicting information and the computers were too. so the plane has multiple sensor multiple pitot tubes, et cetera. what happens this pitot tube says this this pitot tube says something else, the computer says i don t know who to believe. i ll take myself off and throw it over to a human being. they were both blocked if my understanding is correct. only temporarily interesting. with all that being said in this particular case and again we don t know what happened but would a pilot be able to get out of a situation in which, like you said maybe it is climbing
