... so which airplane can do a VNAV path, hold speed and make a restriction? I'm thinking the 767 but I never put it through any paces flying the ER.

Yesterday coming into Atlanta the controller said they were using a new ATC system to control arrival rates and that its been working really good for them. I think the acronym was TMU or T-something. But I also just read that newsletter about Atilia and while I applaud the effort to take the criticism head on it still seems to me that without verification from the crew that they are partcipating that the programs benefits cannot be measured or proved. So with that said, if ATC has a new and improved system to handle flow then do we need Atilia?
