The airspace over the UK and surrounding waters from the surface to FL 245 is divided into two Flight Information Regions (FIR); the London FIR and the Scottish FIR. The airspace above the FIR is known as the Upper Flight Information Region (UIR). The airspace within the FIR/UIR is divided into different types using the ICAO Airspace Classification System.
The ICAO Airspace Classification System
The ICAO Airspace Classification System consists of seven classes of airspace, each specifying minimum Air Traffic Service requirements and the services provided. The UK has adopted the ICAO System but for the present only six classes have been implemented. (*No airspace is designated Class B in the UK). Classes A, C, D & E are Controlled Airspace whilst for **Classes F & G Airspace the UK has registered differences from the ICAO Standard so as to allow greater flexibility to VFR flights at and below 3000ft amsl and to allow IFR flight in this airspace without the requirement to carry a radio.
Controlled Airspace – Visual depictions as per current UK VFR Charts:
Class A. IFR flights only are permitted, all flights are provided with air traffic control service and are separated from each other.
Class B. IFR and VFR flights are permitted, all flights are provided with air traffic control service and are separated from each other. *Note – no airspace is designated Class B in the UK
Class C. IFR and VFR flights are permitted, all flights are provided with air traffic control service and IFR flights are separated from other IFR flights and from VFR flights. VFR flights are separated from IFR flights and receive traffic information in respect of other VFR flights.
Class D. IFR and VFR flights are permitted and all flights are provided with air traffic control service, IFR flights are separated from other IFR flights and receive traffic information in respect of VFR flights, VFR flights receive traffic information in respect of all other flights.
