Specifications
for flight information regions, control areas, control zones and flight
information zones
(a) FLIGHT INFORMATION REGIONS
Flight information regions as defined in point 23 of Article 2 to Regulation (EC) No 549/2004 shall:
(1) cover the whole of the air route structure to be served by such regions; and
(2) include all airspace within its horizontal limits, except when limited by an upper flight information region.
Member States shall retain their responsibilities towards the ICAO within the geographical limits of the flight information regions entrusted to them by the ICAO on the date of entry into force of this Regulation.
(b) CONTROL AREAS
(1) Control areas shall be delineated so as to encompass sufficient airspace to contain the flight paths of those instrument flight rules (IFR) flights or portions thereof to which the applicable parts of the air traffic control (ATC) service are provided, taking into account the capabilities of the navigation aids normally used in that area.
(2) A lower limit of a control area shall be established at a height above the ground or water of not less than 200 m (700 ft), unless otherwise prescribed by the competent authority.
(3) An upper limit of a control area shall be established when either:
(i) ATC service will not be provided above such upper limit; or
(ii) the control area is situated below an upper control area, in which case, the upper limit shall coincide with the lower limit of the upper control area.
(c) CONTROL ZONES
(1) The horizontal limits of a control zone shall encompass at least those portions of the airspace, which are not within control areas that contain the paths of IFR flights arriving at and departing from aerodromes to be used under instrument meteorological conditions (IMC).
(2) If located within the horizontal limits of a control area, the control zone shall extend upwards from the surface of the earth to at least the lower limit of the control area.
(d) FLIGHT INFORMATION ZONES
(1) The horizontal limits of a flight information zone shall encompass at least those portions of the airspace, which are neither within control areas nor within control zone, that contain the paths of IFR and/or VFR flights arriving at and departing from aerodromes.
(2) If located within the horizontal limits of a control area, the flight information zone shall extend upwards from the surface of the earth to at least the lower limit of the control area.
EASA regulations define airspace classifications: Flight Information Regions (FIRs) cover air routes, aligning with ICAO responsibilities. Control Areas contain IFR flight paths, with minimum altitude limits. Control Zones protect IFR flights near aerodromes. Flight Information Zones cover remaining airspace used by arriving/departing flights.
