For the United Kingdom, the classifications of airspace are covered in detail in the UKAIP ENR 1-4, and in Chapter 14 of this book. The C/assification by Letter of Control/ed Airspace. Control Zones (CTRs) may be one of several dasses of airspace. Heathrow CTR is Class A airspace. London City and Birmingham CTRs, like most UK CTRs, are designated Class D airspace. In Germany, all CTRs are Class C. In the Netherlands, most CTRs are Class C. Amsterdam/Schiphol CTR is Class C, Dusseldorf CTR is Class D, Oostende CTR is Class C, Merville CTR is Class E. Brussels CTR, as depicted in Figure 5.11, is Class c. Figure 5.11 Brussels CTR is C/ass C Airspace. Figure 5. 12 The U/le TMA is C/ass D. Merville CTR is Class E. 90
CHAPTER 5: AIRSPACE D/VIS/ON AND AIR TRAFFIC SERVICES (ICAO) Control Areas (CTAs) and Terminal Control Areas (TCA or TMA) may be Class A, B, C, D or E airspace. Most UK CTAs are Class D. The CTA above Heathrow, which is at the junction of several airways and bears the classification of Terminal Control Area (TMA), is Class A. The Lille TMA, above the Merville CTR is Class D (See Figure 5.12, opposite.) Airways can alsa belong to several airspace classification categories. For instance, in the United Kingdom, all airways are Class A, whereas in Portugal, below Flight Level 245, airways are Class C. French airways can be Class E, up to Flight Level 115, and then Class D up to Flight Level 195. lrish airways can be Class C up to FL 245. (See Figure 5.13.)

Upper Information Regions (UIRs) are invariably controlled airspace. In the United Kingdom, UIRs are Class C airspace. The C/assification by Letter of Uncontrol/ed Airspace. Uncontrolled airspace is classified as Class For G. Class G covers the vast majority of uncontrolled airspace, being the Open FIR where aircraft may operate without ATC clearances or constraints. Advisory Routes (See Figure 5.8, Page 87) within uncontrolled airspace are designated Class F. In Class F airspace, flights in accordance with IFR will receive an air traffic advisory service. VFR flights will receive a Flight Information Service, if they request one. Pilots flying VFR in Class F airspace should, however, consider staying clear of the advisory route itself, and, if they wish to cross the advisory route, make contact with the responsible Air Traffic Service Unit (ATSU), 1 O minutes before crossing. On contacting the ATSU , pilots should be prepared to give position, level and the appropriate time information, as in a routine position report. Airspace divisions and classifications are likely to continue to evolve, especially in the European Area, with the advent of the "Single European Sky." 91
