Is it worth getting a Basic Service? From a Farnborough perspective – yes it is. Under a basic service we will provide you with information if requested, usually identify traffic and issue a discreet squawk. Monitor on radar to help you avoid controlled airspace, give traffic information if a definite collision risk exists and finally provide assistance if anything goes wrong, either directly or liaising with D&D.
Forgive me, but isn't that precisely what a Basic Service is not?
When I was passing Farnborough over the past 3 weekends I was pretty much ignored throughout the flight, was not given a discrete squawk and was never given traffic information.
The reason - controller workload.
I think what you are describing is Traffic Service and that is by no means available.
