This book is excellent for first time readers. However anyone looking for updated information in this 3rd Edition is going to be a little disappointed. Not all sections have received the update treatment, since the last edition published in 1993. The most obvious problem is how the author deals with Stansted airport. The chapter dealing with this (C.9), is repeated verbatim from the second edition, and takes no account of the substantial development since 1992.There is no mention of the new terminal, or anything in the supplement section to advise readers of the Stansted Express service from Liverpool Street.It may be down to the publishers in respect of what is updated with each edition, but since other data has obviously been amended, it remains a mystery as to why such a glaring error could have been made. Other than that, the book is genuinely a good laymans' guide to Air Traffic Control in the UK, and as stated previously, wil give new readers a good grounding in the subject.
