Airline Pilot on Airbus 320, Aircraft Mechanical Engineer, and Professor of Mathematics, I teach air navigation, aircraft performance, flight mechanics and Meteorology. In order to study these modules well, I focus my pedagogy on the understanding of the basic concepts in physics and mathematics relating to the notions to be assimilated in these certificates, that is to say that by studying a particular course we will gradually come back to the physical and mathematical prerequisites necessary for understanding the course, in order to understand the why of things and thus ensure that the subject no longer has any secrets for you. Success in MCQ tests will only be a consequence of your mastery of the different concepts and not the result of an uncertain cramming of databases. You will have access to resources, course summaries, explanatory diagrams that I have refined throughout my 5 years of experience as an ATPL instructor.
