Heathrow Director, You seem to think I am joking or something. Nav Canada are intending to use ADS-B over the Hudson Bay area to give a 'radar like' service above FL290 - they have a good business case and are definitely going ahead. Similarly, Airservices Australia will be using it for the whole interior of Australia. UPS, the parcel operator, have equipped their B767 and B757 fleet and using it at Louisvilles and have proved that it works - they are reducing arrival fuel burn, noise and environmental emissions. The FAA are investing around $6.0m to equip some US Airlines aircraft so that they can conduct trials of suitable cockpit displays at Philadelphia. I could add many more examples but clearly you are sceptical! I think even the Laughing Policeman might like it one day.
