A Diploma in Aeronautical Engineering does not necessarily prepare you to be a pilot, but rather gives you the technical and mechanical knowledge of an aircraft, which is very helpful in becoming a good pilot. This diploma program focuses on aircraft design, aircraft maintenance, and operation, including the study of aerodynamics, propulsion systems, aircraft structures, and aviation safety. Understanding these concepts can give you an edge during pilot training, since you will be more technically sound about how aircraft work. Becoming a pilot requires specialized pilot training at a recognized flight school and obtaining licenses like the Commercial Pilot License (CPL) or Private Pilot License (PPL). This knowledge about aircraft systems complements the pilot training in addition to complementing knowledge learned from diploma programs, and is of very high use while ground schooling or even sitting on the theoretical examination. It certainly doesn't supplant the flight formal training, but rather a platform towards getting onto an aviation job whether it's to become a pilot or just as technical expert.
