Are the materials meant to replace the books of examination questions that one can buy from Aerotraining, Aviation Publishers and other sources?
No. Those online examinations or books of questions are an essential part of preparing to take the Transport Canada examination. The materials from Farmhall Aviation Training, while focused firmly on the Transport Canada syllabus, are more general. The texts go beyond what is strictly needed for the Transport Canada examinations and are designed to make you a rounded and knowledgeable pilot. The questions are generally not multiple choice as they are on an examination—they are open-ended and designed to stimulate discussion and thought.
