Iran CAO PPL Theory study guide
Iran CAO PPL Theory · Work through your exam, one topic at a time.
The Iran CAO PPL Theory Examination is the written knowledge stage of the Private Pilot Licence issued by the Civil Aviation Organization of Iran. It is aimed at student pilots training at an approved flight school who need to demonstrate ground knowledge before or alongside their flying hours, whether they intend to fly recreationally or build toward a professional licence. The Iran CAO PPL Theory study guide has 10 sections and about 2,936 words.
01Air Law and ATC Procedures
This domain checks whether you can apply ICAO Annex 2 rules and Iranian AIP procedures to VFR flight: documents, airspace, weather minima, right of way, cruising levels and clearances. ICAO Annex 2 is the baseline; Iran's AIP publishes national differences and airspace classification.
338 words, about 2 min02Aircraft General Knowledge (Airframe, Systems, Powerplant, Instruments)
This domain tests practical system knowledge for the PPL: how the airframe carries load, how power and fuel systems work, and how pitot-static and gyroscopic instruments fail. A semi-monocoque fuselage carries load through stressed skin, stringers, frames and spar attachments.
315 words, about 2 min03Flight Performance and Planning (Mass and Balance, Performance)
This domain tests whether you can compute mass, centre of gravity and aircraft performance, and whether you can recognise when density altitude, wind, slope or obstacle clearance makes a planned flight unsafe. Mass and balance uses mass, arm and moment.
320 words, about 2 min04Human Performance and Limitations
This domain tests how hypoxia, fatigue, stress, illusions, vision and decision-making affect pilot performance, and whether you can choose the correct recovery action. Hypoxia reduces oxygen to the brain; early signs include euphoria, impaired judgement and tingling.
277 words, about 1 min05Meteorology
This domain tests weather interpretation for VFR flight: pressure and altimetry, stability, clouds, fronts, icing, thunderstorms, dust and the decoding of METAR and TAF reports. Pressure decreases with height.
304 words, about 2 min06Navigation (General, Radio, Instrument)
This domain tests chart work, the triangle of velocities, heading and track conversions, and basic radio navigation using VOR, DME, NDB, ILS and GNSS. Track is the path over the ground; heading is where the nose points.
281 words, about 1 min07Operational Procedures
This domain tests normal and emergency procedures: preflight planning, fuel, alternates, take-off and landing, engine failure, fire, radio failure and runway safety. Preflight planning confirms documents, mass and balance, performance, weather, NOTAMs, fuel and alternates.
263 words, about 1 min08Principles of Flight
This domain tests lift, drag, angle of attack, stall, load factor, stability and control, including how speed, mass and bank angle change aircraft behaviour. Lift increases with angle of attack up to the critical angle, then decreases.
285 words, about 1 min09Communications (VFR and IFR Phraseology, Radiotelephony)
This domain tests standard radiotelephony: call signs, phonetic alphabet, numbers, clearance readback, distress and urgency calls, and position reporting. Use the aircraft call sign consistently.
263 words, about 1 min10Radio Navigation and GNSS
This domain tests the practical use of VOR, DME, NDB, ILS and GNSS, including indications, limitations and failure modes relevant to PPL navigation. VOR provides magnetic radials from the station.
