This is a direct from the printer version of Captain Mike Ray's "737 Classic Pilot Handbook" that has been used successfully by airline pilots for years. With the introduction of their fabulous simulation, the IXEG 737 developers are recommending this book as an EXCELLENT compliment to their product. This book is a terrific source of information for the serious simmer. With a whole flight profile from Cold Dark start to parking/secure ... it lays out in intricate detail all the steps to "fly like the pros!"
