This book is geared to the United Kingdom and therefore 'all' the listed frequencies and cited airports are located in England, Ireland and Scotland! Even any discussion on airband radios are based on UK models and ATC discussion focuses on London and other large UK airports. Ditto the rules and procedures because the UK has its own civil/commercial regulatory agencies, departments and agencies and hence the US FAA nor NTSB [et al] play no part in the book since it's based on the system and procedures of another nation. The UK.
Now, and in all fairness, had I taken the time to see that the author, David J. Smith, was/is an air traffic controller in 'Liverpool', then I would have looked further for a book that focuses on US procedures and airband frequencies. 'All' the Appendix listings [and they are considerable] deal with UK [England/Ireland/Scotland] centers and geographical locations. As well as various UK oriented rules and regulations for "Aerodrome Control" [sic]. The only helpful info came from one chapter [7 pages], "Oceanic Control and HF listening" and some similar but by no means universal [UK/US differences] air traffic terminology. The Morse Code listing notwithstanding. I also found discussion of navigational aids to be rather dated.
Fortunately, I purchased this book from an Amazon vendor, used, and I paid considerably less than what it sells for at Amazon [** as I do this review, the paperback book sells for $27.95] and which I thought was a rather hefty cost [new] but, as I say, I bought it used for a third of that cost [plus shipping] but it should have been mentioned in the product write-up that the book focuses almost entirely on the United Kingdom and in particularly England's major airport in London.
For someone living the UK, well, 'then' those many frequency and individual 'UK' airport listings [and book comment therein] would be of much more utility to the reader.
