Aircraft General Knowledge PPL study guide — systems and engines

Aircraft General Knowledge covers how the aircraft is built and how its systems work. It is broad — engines, airframes, instruments, electrics, and fuel — but each area follows logical principles.

Main areas

• Piston engine operation and instruments
• Airframe construction and controls
• Electrical and vacuum systems
• Fuel systems and carburettor icing
• Flight instruments and errors

How to study

Build mental models of how systems connect. For example, understand the full fuel path from tank to carburettor, and what happens when a component fails.

Exam focus

Questions often describe a symptom and ask for the cause or the correct pilot action. Link each system to its failure modes and the cockpit indication you would see.
