Effective human factors is critical to the development of safe and proficient pilot. Over 80% of plane crashes can be attributed to pilot error in some degree. Don’t become a statistic, make sure you are well informed and prepared. The Advanced Handbook applies more particularly to pilots who fly commercially – corporate, charter, commuter, and airliners or those who fly with more sophisticated equipment. This volume covers issues such as aircraft complexity, altitude and duration of flight , jet lag and faitgue, and the pressures of the commercial enviorment, all of which can affect the safety of flight. As in the Basic Handbook, the principles in this handbook can apply equally to others in the aviation system.
