This book's intention is to explain to any pilot the theory of HPL - Psychology, a new subject in any JAR FCL license. Any fresh pilot student is required to know these subjects for the theoretical exam from Private Pilots License right up to Airline Transport License.
But ... .. JAR - FCL also requires any's pilots training to follow these rules of efficient human psychological behavior in the interest of improved safety. So the book was written in a very easily understandable way to make the retaining of knowledge easier and to help in passing the HPL Psychology exam and to remain aware of the subject in practical flying too.
