What to expect on the real exam

AGK is one of the most technical ATPL subjects, split into two separate written papers: Airframe & Systems, and Powerplant. Both require a solid understanding of how aircraft systems operate and interact with each other.

About This Subject

Why Aircraft General Knowledge matters

AGK covers the design, construction, and operation of every major aircraft system. From understanding why a turbofan bypass ratio affects fuel efficiency, to how hydraulic pressure is maintained during a pump failure — this subject demands both breadth and depth.

For EASA candidates, the syllabus is aligned with CS-25 certification standards. The questions in this bank reflect both the technical depth and the application-style reasoning required in the real exam, including system interactions and failure scenarios.
