In "An Aviator's Field Guide to Middle-Altitude Flying," author Jason Blair shares his experiences with various piston-engine, twin-engine aircraft used for flying at altitudes ranging from 10,000 to 25,000 feet above sea level. This book covers the main flight phases and specific issues for pilots operating aircraft at these altitudes, including performance and fuel planning, emergency situations, descent planning, navigation, weather, aircraft modifications, oxygen consumption, weight and balance, pilot qualifications, and insurance.
With insights that cannot be found in other training manuals or within typical flight training operations, and gained through many years of instruction and checkride issuance, Blair's book will help aircraft owners or operators assess the risks and challenges inherent in middle-altitude flying, develop effective flight planning practices, and take advantage of the enhanced performance and capabilities offered by these higher operations.
