AFIS units are tasked with the provision of FIS and Alerting service within their jurisdictional airspace, without being considered an ATC unit; aerodromes identified as “AFIS aerodromes” maintain the status of “non-controlled” aerodromes. The interface between AFIS and ATC, attention is drawn to the coordination in that phase of flight when an aircraft – or more than one – is transiting from an AFIS to ATC and vice a versa. This is particularly relevant when the aerodrome is surrounded by controlled airspace where instrument procedures’ profiles extend through both volumes of airspace. To enable flights to operate safely between AFIS and ATC and vice a versa.
IFATCA Policy is:
At aerodromes where Aerodrome Flight Information Service is provided and are directly adjacent to controlled airspace appropriate LOAs are to be adopted defining the interface between AFIS units and the relevant ATC unit(s) in order to provide detailed operating and coordination procedures.
