Civil Aircraft Markings continues to be the enthusiast's 'Bible' for its detailed and comprehensive listing of every single British registered aircraft, microlight, balloon and glider. The book also includes overseas airliners that can been seen in British airspace. The total number of aircraft on the register is in excess of 20,000 so this is a monumental work of reference. Airline codes for those carriers most likely to appear in or over the UK and radio frequencies for the large airports are also listed. The detailed information remains easily and instantly accessible. It is alphabetically arranged by aircraft code and gives model details and owner/operator information.
