About the CASA PPL Theory Exams
Before you can be issued a Private Pilot Licence (Aeroplane), PPL(A), in Australia, you must pass a series of written theory exams administered by the Civil Aviation Safety Authority (CASA) through the Aspeq examination system. Each exam covers a specific subject area relevant to safe private flying operations. All exams must be passed before you can complete your licence application, and they must be completed within a set timeframe from your first exam attempt.
The PPL(A) theory exams cover seven subjects:
- Air Law and Operational Procedures: CASR regulations, airspace classifications, ATC procedures, flight rules (VFR), pilot responsibilities, and aerodrome operations
- Navigation: chart reading, VOR and NDB navigation, dead reckoning, position fixing, ERSA, and flight planning
- Meteorology: weather systems, TAF and METAR decoding, wind and turbulence, icing, thunderstorms, and aviation weather products
- Aerodynamics and Theory of Flight: lift, drag, stall, stability, load factors, high-lift devices, and factors affecting performance
- General Aircraft Technical Knowledge: aircraft systems, engines, fuel, instruments, electrical systems, and airworthiness
- Flight Performance and Planning: weight and balance, take-off and landing performance, cruise performance, and fuel planning
- Human Factors: aviation physiology, hypoxia, spatial disorientation, fatigue, decision making, and crew resource management basics
Important: The pass mark for every CASA PPL theory exam is 70%. If you fail a subject, there is a compulsory 14-day waiting period before you can retake it. All PPL theory exams must be completed within 24 months of first sitting any subject, results expire after this window and must be retaken.
