Iran CAO CPL Theory

It is multiple choice, sat subject by subject, either on computer or on paper at CAO-approved examination centres. Papers are written in Persian with standard technical terms frequently shown in English. A pass in every subject is required before the skill test. The CAO publishes the current sitting schedule, centre list and registration steps.

The difficulty is breadth, not trickery. Twelve subjects must each be passed separately, so you cannot carry a weak area with a strong one. Candidates generally report the heaviest workload in Performance, Mass and Balance, Flight Planning and Air Law. Questions are usually direct applications of syllabus material rather than puzzles.

Those details are set by the CAO and change between syllabi, so no figure quoted on a third-party site should be trusted. Check the current CAO examination syllabus and the candidate circular issued for your sitting, which state the paper structure, time allowed and minimum pass mark for each subject.

Yes, retakes exist, but the conditions - waiting periods, number of attempts, whether a partial credit is retained - are set by the CAO and are not uniform over time. Confirm the current rule in the candidate circular before you plan a resit, and do not rely on forum posts describing older regulations.

The CAO determines how long passed subjects remain credited toward licence issue, and this can differ between syllabi revisions. Ask the licensing office, or check the current candidate circular, at the start of your studies - not at the end. It directly affects how you sequence the skill test and hour building.

Start with Air Law and Principles of Flight for foundations and momentum, then Aircraft General Knowledge. Group Performance, Mass and Balance and Flight Planning together because they share numerical methods. Take Meteorology and Navigation next, and leave Operational Procedures and Communications until shortly before the skill test, when they make most sense.

Underestimating Air Law as pure memorisation; weak unit conversion and mental arithmetic under time pressure; never practising numerical performance and flight-planning questions with a proper flight computer; misreading Persian wording where the English technical term differs; and leaving Communications and Radiotelephony to the final weeks with no phraseology practice.

Very. Even though the papers are in Persian, standard technical terms are often given in English, and ICAO radiotelephony phraseology is English-based. Build a bilingual glossary as you study each subject, and practise reading the English term alongside its Persian equivalent so an unfamiliar wording cannot derail an otherwise answerable question.

Persian is the normal delivery language, with English technical terms embedded. Whether an individual subject can be sat in English is an administrative question for the CAO, not something to assume. Confirm it with the examination centre or licensing office when you register, especially if your ground-school training was in English.
