Re: Big news in Sweden today: 40 sec from disaster
ATC watcher,
Absolutely true. I neglected to add those additional cases to the TCAS alerts. I have found in practice that pilots tend to moderate descent rate at the TA, or following the controller's advice of nearby traffic. That usually prevents the RA from occurring. At least in our patch of sky.
As to what the clearance to the pilots was, and what would have been the result had they continue to fly those clearances...does anybody know that yet?
My point is that had the clearances been to continue toward each other at 90 degrees/same level, the fact that TCAS provided the space does not a seperation make, as seem to be implied by some posts.
