ATC vs TCAS
Quote:
"757 crew responded incorrectly to ATC "
because ATC never asked that crew to descend. It was TCAS that made them to descend.
It is easy to give statements from in front of our computers. But on every day of our duty we always follow ATC instructions (whether we are from West or East), and any TCAS TA makes us see the picture, before RA comes out. We can all swear to act exactly like the 757 crew did. But in the heat of moment or a pressure, TA, RA and in the same time LOUD command from ATC, to start and expedite descend they did what they did.
And 757 crew did everything correct regarding TCAS and died.
We all need even love TCAS. "I can see you on my TCAS"
Main question here is how this tragedy could have been avoided. We all know one answer:
If both parties responded correctly to TCAS and incorrectly to ATC.
Second answer may be about new TCAS perhaps.
