tower tapes have a time hack. It was my gues, you confirm it.
One more guess: if you are an ATC you do not only interfere with the flights (which is important enough) but also with the control centers in the neighbourhood to hand them over the flights or to take them. Additionally my guess is that there is a preplanning: i.e. AAL11 leaves Boston every day at a certain time, so the responsibility for i.e. Cleveland ATCC begings every time moer or less in the same time. To plan the amoint of ATCs needed at the screen my logical guess is: they must coordinate the times, especially when changing time zones.
Untill here: Am I right?
Then my guess is there is a central atomic clock radioing the time to important institutions including the towers. It makes sense. In Germany it is managed that way. Okay - this you do not know as you say.
>>>Maybe. I don't have this information.<<<
Especially the UAL93 differs from 10:10 to 10:03. Just google it out. It is as I tell you. And they do not explain it. Similar with AAL77: from 09:44 to 09:38 (but here I am not sure if these times were "officially" stated, and it is not so much difference and not important)
>>>Yes. This is easy<<< And you drive us crazy by telling us that times can differ untill the FBI reveals the very end of their "investigations"? Why? Even if you do not see it as relevantly (because you do not see the relevance for the investigations in 911) - it would have been polite to acknoledge that dulce and I judge it as relevant. It is - in every criminal case. Not only minutes. Seconds.
Now the question: is Dulce right or wrong when he states that ACARS (besides all errors and failures and so on) NORMALLY exchanges relevant data with the towers? If "yes" I do not understand why the time data are not exchanged. Even when the clock on board is different - but an exchange module must comprise time data.
Is that right or wrong?
And I am sorry that I do not understand your "6a" answer. What is 6a?
