TCAS is great but if there is a delay in reacting to the TCAS advisory by either plane, the Advisory can be reversed which can lead to confusion or disaster.

Best if these situations don't occur and seeing as traffic wasn't heavy at the time, it shouldn't have happened at all. Four warnings were received before TCAS kicked in.....

Thats you so pprnkof.


For your info an Advisory is just that-an advisory. It does not command climb or descent by the flight crew.

Well done on that nugget of wisdom.

Traffic levels are not relevant - all elevated traffic does is increase the risk-but fundamentally all you nead for an air prox is 2 aircraft to present-no more than that. Its a well known human factor that after a spell of busy traffic that statistically you have the same risk or even higher of missing something. Throw in a long duty 9.75 hrs in this case and being close to end of duty and human factors take on even greater importance.

.....
Every atco gets lots of these warnings every day-the system is not 'smart' and so does not know exactly what the controller is intending to do so it generates a lot of what are in reality false warnings. A well known factor is that if you have a system that generates lots of false warnings then a tendency can grow to where full attention is not given to these warnings. Thats a general comment and not specific to this case.We make decision calls ,hundreds of them everyday, just like this one-where our judgement tells us yes we can keep descending this aircraft and with a sufficeintly high rate of descent instruction given then it wont be problem.
But humans are human and every single one of us will not go thru our chosen careers without making a mistake somwhere. The trick is to learn from these and make sure the reason(s) are understood to why it happened. You can bet your bottom dollar that anyone who has had an airprox learns a huge lesson and will carry that with them for the rest of the days.



Your sum total of knowledge appears to be what you read in the indo yesterday.

Journo digging are you.

The only one throwing stones is yerself fella! Chill! And yes I am as prone to making mistakes as anyone, obviously. But what was your point?

A resolution advisory by a TCAS II system, should be given an immediate, high priority reponse (if possible) and should always take precedence over ATC.

By the way I'm not digging.

From AAIU report:

[emphasis added]

Which implies (if not states) that ATC was oblivious to the developing conflict.

Whereas, also from from the report
