Iran CAO ATPL Theory study guide
Iran CAO ATPL Theory · Work through your exam, one topic at a time.
The Iran CAO ATPL Theory Examination is the theoretical knowledge component of the Airline Transport Pilot licence issued under the Civil Aviation Organization of Iran. It is aimed at experienced commercial pilots progressing to ATPL, and at frozen-ATPL students who complete the theoretical papers before building the flight hours needed for full issue. The Iran CAO ATPL Theory study guide has 13 sections and about 3,471 words.
01Air Law and ATC Procedures
Iran CAO ATPL Air Law questions test ICAO Annex 2/11/12 and the Iran AIP, not memory of domestic statute numbers. You must know clearance content, readback, airspace classes, separation responsibility and the rules that change at the transition altitude.
299 words, about 1 min02Aircraft General Knowledge - Airframe, Systems, Electrics, Powerplant and Emergency Equipment
This domain covers transport-category airframes: structural loads and fail-safe design, flight controls, pressurisation, fuel, hydraulics, electrical generation/distribution, powerplant and fire/oxygen equipment. Expect system-logic questions, not type ratings.
302 words, about 2 min03Flight Planning and Flight Monitoring
Flight planning questions test fuel policy, route/altitude selection, NOTAM/AIP use, alternate requirements and in-flight monitoring. Iran CAO expects ICAO Annex 6 logic applied to the Tehran FIR and the operator's approved method.
323 words, about 2 min04Human Performance and Limitations
Human performance questions test hypoxia, decompression, fatigue, circadian rhythm, sensory illusions, decision-making and crew resource management. Iran CAO uses ICAO human-factors language, so learn the physiology and the operational countermeasures.
282 words, about 1 min05Meteorology
Meteorology covers pressure, wind, clouds, icing, thunderstorms, turbulence, visibility and Iranian local effects: Zagros mountain waves, Alborz lee waves, summer dust and winter fog. You must read METAR/TAF and apply QNH/QFE correctly.
306 words, about 2 min06Navigation - General Navigation
General navigation tests the Earth's shape, coordinate systems, chart projections, great circles, rhumb lines, time and magnetism. Calculations must be shown, not guessed.
257 words, about 1 min07Radio Navigation and Instrumentation
Radio navigation covers VOR, DME, NDB/ADF, ILS, GNSS, radar and the interpretation of cockpit indications. Expect questions on radials, bearings, intercepts and approach geometry.
251 words, about 1 min08Operational Procedures
Operational procedures covers normal, abnormal and emergency drills, take-off and approach minima, depressurisation, engine failure, fire, diversion and fuel management. Iran CAO expects aircraft-general procedures, not a specific type checklist.
252 words, about 1 min09Principles of Flight
Principles of flight tests lift, drag, stability, control, high-speed flight and load factor. Iran CAO questions often use simple numerical relationships.
245 words, about 1 min10Communications - VFR and IFR
Communications tests ICAO standard phraseology, readback, distress/urgency, position reports and radio failure. Iran CAO uses English radiotelephony in international operations; clarity and standard phrases matter.
244 words, about 1 min11Mass and Balance
Mass and balance tests mass limits, CG limits, moment calculations, %MAC and loading philosophy. Expect a numerical question with a table or simple data.
225 words, about 1 min12Performance
Performance tests take-off/landing distance, climb gradient, obstacle clearance, density altitude, V-speeds and limitations. Iran's high aerodromes and summer temperatures make density altitude a recurring theme.
247 words, about 1 min13Aircraft General Knowledge - Instrumentation
Instrumentation covers pitot-static, gyroscopic, magnetic, EFIS and warning systems. Questions test interpretation and failure modes.
