I'm still waiting to hear the clarification of what the vectoring off the SID is going to mean in practice. And what does "mostly" in the NPR mean ?
Hopefully it is worked out before they use it !
These instances will presumably be reported on, along with use of the other freedoms, so we'll see then what it's all about, assuming that individual flights which have been subject to this freedom are identified as such.
Having said that, it's only 6 days until the start of Phase II and a number of the Phase I reporting requirements still haven't been fulfilled: there's no detailed report for February, many of the daily summaries have errors which BAA have undertaken to rectify, but haven't (yet), and the promised data showing in detail which flights used which freedoms has still to materialise.
