BUZZC152, the book you are thinking of is probably 'COMBAT READY' by David Mason. Published by Airlife, it covers OASC, IOT at RAFC Cranwell, Bulldog (shows how old the book is!), Firefly, Tucano, Hawk, and the Harrier GR7 OCU. Each chapter describes each stage of training in minute detail: a good read. (And no , I don't work for the publishers!)
