Page 3 - Ground Speed News Today

The speeds increase enormously. we do know that the ground speed indicates over 400 miles an hour, so there is some issue that prevented the flight crew from either recovering at an altitude that would have provided them the ability to maintain an altitude above the terrain or there was an issue that prevented them, such as incapacitation incapacitation. thats yet to be determine or confirmed. hopefully, one of the boxes will tell us that. >> john let me come back to you and ask you about the ma...

Largely reclaimed land. 7,000 feet on either runway. and on a good day, you got to really put it down right where you should and get on the brakes really hard and do your job without any mistakes because theres not a lot of margin for error. on a day like today, it gets even trickier of course. low visibility, low clouds and a slick runway. thats a bad combination here. in this case, ashleigh, id like -- i hope chad is still listening. the winds at la guardia right now are about 16 knots, gettin...

Aircraft as far as the differences indicated in the ground speed. >> that answers the question completely jeffrey. now i fully understand. the ones i had mentioned earlier, there were some head winds that turned to tail winds very quickly indicating wind sheer, but if thats only 25 indicated in there, it says it wasnt as severe, so im on board. >> miles, what do you think? >> ive spent a lot of time flying around in thunderstorms in little planes and i can tell you the forecast for winds aloft, ...

There -- this was a surviveable event and someone drowned, of course, youd see water in their lungs and all that kind of thing. all these bits and pieces and factual information will eventually make the bottom line story. but, you know getting them in isolation and trying build a storyline is really unfair at this point. >> you do believe that once we have the black box, well be able to put together more information about the story? >> absolutely. because the data on the flight data recorder it ...

Explain that to us. basically not just the net air speed. >> yes. the indicated air speed, i think, and maybe jeffrey can help me with this but i didnt see that we knew the indicated air speed there. so what were talking about is the distance that it traveled from one point to another and how far it went on the ground speed, indicating -- help me understand this but it looks like the aircraft was then at an extremely high descent rate which would make sense, but at the same time were saying it w...

But beyond that, you. >> caller: really cant tell. the idea that the plane did a dramatic climb, radar notoriously is unreliable for recording that kind of behavior in a plane. so we just dont know. but were going to find out. >> even that radar that were talking about, that the sunday morning herald repeated? >> if it was mode s, still, its an extraordinary climb. >> speak to that a little bit, also because the information -- this was information that was leaked that was given to the sydney mor...

The mode s transponder gives more information but theres a time delay so we really dont know what that was -- what that ground speed was -- or that air speed on the radar was all about. theres a difference like you indicated, between what the airplane senses and the ground speed. so its all subject to possible dis discrepancies. the climb seems extraordinary. they could have gone through a thunderstorm that causes a lot of updrafts in addition to downdrafts. so weather does seem to be related bu...

Played a big role. >> it does. it does. just the climbing wouldnt answer that entire picture. were using that information. if it was a combination of climbing and rapidly rising air thats when we would have some serious, serious turbulence that could damage the aircraft. >> i want to add in one more factor. theres another fact out there. the sidney herald obtained so i radar data and see this excessive climb or excessive speed in climbing. but in contrast the article said the plane traveled as i...

That seems a little implausible to me. 105 knots that was indicated would have been ground speed. airplane sense, airspeed in the air relative to whats going on over the wing that steep rate of climb seems a little unlikely. there are updrafts in a thunderstorm. there are also downdrafts. that rate is certainly possible. it doesnt indicate to me that there was a 20,000-hour skilled pilot at the controls. if that was happening in my airplane instinctively we would disconnect the auto pilot and at...

The way it goes down is bordering on the edge of logic. this analyst was puzzled by the extremely low ground speed he saw, saying the plane was descending at the same speed as a car on the highway. cnn doesnt have this information independent right now. david soucie if its true if its accurate what does it tell you about what happened here? >> well its hard to say because of the fact that they said ground speed. ground speed is just simply that, how fast youre traveling over the ground. if you h...
