This module covers learning content applicable to those seeking a qualification level, CAT A or B1 which allows them to work on turbine or piston engine powered fixed wing aircraft but not both. Under the chapter of Theory of Flight, the already learned knowledge of aerodynamics and flight controls is expanded. High speed flight from subsonic to supersonic is introduced to also include aircraft design and sub-sonic and supersonic airflows through the engine. Further knowledge of aircraft structures, design and inspections is given as well as most aircraft systems ranging from the environmental control functions to airframe fuel and hydraulics and aircraft avionics/data management systems is also covered.
