Any information regarding relative bearing obtained using a radar set is Radar Information. If such radar information is provided as a service then that service is a Radar Information Service. The Pilot/Controller agreement is required to reflect that. It is perfectly clear from definition that Flight Information Service is a non-radar service. Why, then, are the two services confused so often by air traffic service providers? Do some not understand the difference? If they do and elect to upgrade the service at their own instigatation then the service should be upgraded accordingly for the duration of the upgrade no matter how long or short. Either it is a radar service or it is not. There should be no doubt as to which service is being provided either in the mind of the service recipient or the service provider.
