This book contains questions for the EASA Private Pilot's Licence, but it could be valid for almost any country, making due allowance for air law, meteorology and various maps, which have been chosen to be as neutral as possible. There are separate chapters for each subject involved. Answers (with explanations**) are given at the end of the book.
