The future of CNS/ATM is looking good.
CPDLC will improve comms, RNAV and GNSS will be great for navigation and ADS should improve surveillance. As far as I can see the benefits are going to be massive. More safety, more capacity in busy airspace and more direct flight (which alone brings a whole heap of benefits like lower fuel burn and less emissions....)
But does anyone have any reservations about all this new technology?
