Classifications & Division

Controlled Airspace Uncontrolled Airspace Classifications RVSM


EPWW Airspace is divided into two Flight Information Regions (FIR's). At and above FL245, this is known as the Upper Flight Information Region and below FL245, it is known as the Lower Flight Information region.

Classification of Airspace

The classification of airspace determines which flight rules apply and the minimum services that are to be provided in that airspace. There are 3 types of airspace in the EPWW; A to G, A being the most restrictive and G being the least restrictive.

Class C:

  • IFR and VFR
  • ATC Clearance before entry
  • Comply with ATC Instructions
  • IFR flights separated from other IFR and VFR flights
  • VFR flights separated from IFR flights
  • Traffic Information on VFR flights passed to VFR flights, with avoidance advice if requested

Class C airspace in the [ICAO] can be found between FL195 and FL245 throughtout the [ICAO].

Class D:

  • IFR and VFR
  • ATC Clearance before entry
  • Comply with ATC Instructions
  • IFR flights separated from other IFR flights
  • Traffic Information on VFR flights passed to IFR flights, with avoidance advice if requested
  • Traffic Information on VFR flights and IFR flights passed to other VFR flights

Class D airspace in the [ICAO] can be found in most control zones around airports.

Class G:

  • IFR and VFR

Class G airspace is Uncontrolled Airspace - More than half of the [ICAO] airspace is class G, and can be found all around the country.
