In An Aviator's Field Guide to Middle-Altitude Flying, author Jason
Blair shares his experience in a variety of piston, twin-engine aircraft
commonly used to fly at altitudes between 10,000 and 25,000 feet MSL.
This book covers the major phases of flight and the specific
considerations for pilots who operate aircraft at these altitudes,
including performance and fuel planning, emergencies, descent planning,
navigation, weather, aircraft modifications, oxygen use, weight and
balance, pilot qualifications, and insurance.
With insight not found in other training manuals or part of typical
flight training operations, and gained through his many years
instructing and giving checkrides, Blair's book will help the pilot
owner or operator evaluate the risks and challenges unique to
middle-altitude flying, develop effective flight-planning practices, and
take advantage of the increased efficiencies and opportunities offered
through these higher operations.
