Not necessarily true. I'll believe it when I see it but from what I've been told, Abacus is a lot more robust in what it can do and track. There are some items that NATCA will try and negotiate to be included in the TCI formula as a result. For instance, they plan to make a change so that sustained operations of longer than 30 minutes will count again.
For terminal folks, I believe they would also like to add some sort of ground complexity formula based on operations and size of the airport. That would really help places like MDW, DCA, LGA, SAN, etc.
