I'm hoping the FAA isn't anticipating technology to save them. We got a bulletin (which constitutes adequate training) on in flight CPDLC frequency changes and clearances in en route airspace. It's turned on in Indy center and I believe KC center now. The timetable is to turn it on in the en route centers over the next six months or so. I was doing some flying through Vancouver center recently and saw it for the first time myself there. It's really cool and seems to work well for those properly equipped. Could potentially make thing easier for ATC, going forward. I don't see it useful at a busy terminal like N90 though.
