The theoretical PPL(A) syllabus established by EASA covers nine subjects. Some require memorization, others demand analytical understanding or mathematical calculation. Here is what you need to know for each subject — and how to study efficiently.
In a Nutshell (30-Second Summary): The EASA PPL(A) theory exam covers 9 subjects. Three are heavy on memorization (Air Law, Communications, Operational Procedures), three rely on understanding core concepts (Principles of Flight, Aircraft General Knowledge, Human Performance), and three combine calculation with methodology (Navigation, Meteorology, Flight Performance & Planning). Always study in blocks of 2 or 3 subjects.
1. Air Law
What you will learn: Rules of the air, airspace classification (Classes A through G), VFR visibility and cloud separation minima, right-of-way rules, aerodrome signals, licensing rules, and mandatory ship’s papers.
How to study it: Air Law requires memorizing specific figures (overflight altitudes, weather minima, airspace limits). Spaced repetition flashcards are ideal for locking in these values. Pay extra attention to airspace rules and right-of-way scenarios.
2. Aircraft General Knowledge
What you will learn: Airframe construction, flight controls, four-stroke piston engines, propellers, fuel systems, electrical systems, and gyroscopic & pitot-static flight instruments (altimeter, airspeed indicator, attitude indicator).
How to study it: Focus on understanding system mechanics. If you understand how a carburetor or altimeter works, you can easily answer variations on questions, including engine failure or instrument blockage scenarios.
3. Flight Performance & Planning
What you will learn: Mass and balance calculations, center of gravity (CG) limits, takeoff & landing distance performance charts, density altitude, wind components, and fuel consumption planning.
How to study it: This subject tests systematic calculation. Practice working through standard mass & balance and performance chart calculations until the steps become second nature.
4. Human Performance
What you will learn: Pilot physiology (hypoxia, hyperventilation, spatial disorientation, ear & sinus pressure), vision, hearing, fatigue, stress management, decision-making, and Threat and Error Management (TEM).
How to study it: This is one of the most engaging subjects, but don’t underestimate it: questions test exact details (blood alcohol limits, hypoxia symptoms, somatogyral illusions). Active recall flashcards make quick work of it.
5. Meteorology
What you will learn: Atmospheric structure, pressure systems, winds, air masses, fronts, cloud types, icing, thunderstorms, fog, and reading METARs, TAFs, and synoptic weather charts.
How to study it: First master the physical processes (air parcel adiabatic cooling, thunderstorm development phases), then practice decoding METAR and TAF reports extensively — this is guaranteed to appear on the exam.
6. Navigation
What you will learn: Aeronautical charts, true vs magnetic headings, drift angle, triangle of velocities, groundspeed, fuel burn, magnetic variation and deviation, and radio navigation basics (VOR, NDB/ADF, GPS).
How to study it: Often considered the most challenging subject. Master core calculations (1-in-60 rule, wind correction angle, flight time) and practice past paper problems repeatedly.
7. Operational Procedures
What you will learn: Aeronautical Information Publications (AIP), NOTAMs, departure & arrival procedures, emergency protocols (engine failure, engine fire, forced landing), mountain flying, and overwater operations.
How to study it: This subject overlaps with Air Law and Aircraft General Knowledge. Review it towards the end of your preparation when related concepts are already fresh in mind.
8. Principles of Flight
What you will learn: Lift, drag, angle of attack, airfoil polar curves, stalls, spins, aircraft stability, flap & trim effects, and the maneuvering flight envelope.
How to study it: Prioritize conceptual understanding. A clear mental diagram of airflow over a wing or forces in a turn is worth pages of memorized text.
9. Communications
What you will learn: Standard VFR radio phraseology, aviation alphabet, readback procedures, distress (MAYDAY) and urgency (PAN PAN) calls, frequency usage, and loss of communication procedures.
How to study it: Learn the exact phraseology — approximations lose marks. OACI phonetic alphabet, mandatory readback items, and emergency calls should be second nature.
Overview & Difficulty Summary
| Subject | Primary Study Style | Perceived Difficulty |
|---|---|---|
| Air Law | Memorization | Medium |
| Aircraft General Knowledge | Conceptual Understanding | Medium |
| Flight Performance & Planning | Calculation | High |
| Human Performance | Memorization | Low |
| Meteorology | Understanding + Decoding | High |
| Navigation | Calculation + Method | High |
| Operational Procedures | Memorization | Low |
| Principles of Flight | Conceptual Understanding | Medium |
| Communications | Memorization | Low |
Final Recommendation
Do not attempt to study all nine subjects simultaneously. Group them into complementary pairs (e.g. Principles of Flight + Aircraft Knowledge, or Navigation + Meteorology) and validate each pair with past paper quizzes before moving on. This is the exact method built into AltiPrep: subject-by-subject practice, real-time readiness telemetry, and full mock exams to ensure you are 100% ready on test day.

Frequently Asked Questions
How many subjects are in the PPL theory exam?
The theoretical PPL(A) syllabus defined by EASA comprises 9 subjects: Air Law, Aircraft General Knowledge, Flight Performance & Planning, Human Performance, Meteorology, Navigation, Operational Procedures, Principles of Flight, and Communications.
What is the hardest subject in the PPL theory exam?
Navigation and Meteorology are most frequently cited as the most demanding because they combine theoretical understanding, calculations, and chart/document reading. Conversely, candidates good at memorization find Air Law more accessible.
Should I study all 9 subjects at the same time?
No. It is far more effective to study in blocks of 2 or 3 complementary subjects, such as Principles of Flight + Aircraft General Knowledge, or Navigation + Meteorology. This maintains a manageable mental workload while connecting related concepts.
Are exam questions identical for every candidate?
No. Questions are randomly selected from an official question bank. While two candidates won't get identical tests, key themes and recurring question structures appear constantly, which is why practicing past papers is so effective.
