Just a comment on Ba229's statement about "old pilots that don't like it". Being an "old pilot" feel I can comment. I don't think it is an issue of not liking it, or even not willing to change, I think it, atleast for me, is an issue of what the trade off is.
The nice thing about VHF communications is you have a "party line". You can hear other transmissions, you can build a mental picture of where everyone else is around you. It helps situational awareness.
I am all for decreasing pilot workload. In this day and age, it's ridiculous to go across the Pacific or other parts of the world and have to rely on HF
as your primary form of communication.
I have used FANS for a number of years and love it, I just wish there was some way keep the information coming into the cockpit to keep us situationally aware of the traffic in your area.
