About this exam

The CAAB CPL Theory Exam is the ground-subject examination set by the Civil Aviation Authority of Bangladesh for candidates working toward a Commercial Pilot Licence. It is intended for student pilots who have completed (or are completing) approved ground training at a CAAB-recognised flying school and who need to demonstrate theoretical knowledge before and alongside their flight training. The syllabus follows the nine classic ATPL/CPL knowledge areas - air law, aircraft general knowledge, flight performance and planning, human performance, meteorology, navigation, operational procedures, principles of flight, and communications - and the papers are sat as separate subjects, so progress is incremental rather than one monolithic test. Most sittings are multiple-choice, though some subject sittings may include written/descriptive papers, and the authority sets its own pass mark and validity rules.

Preparation is best treated as a long campaign rather than a cram. Work subject by subject, but deliberately link them: meteorology feeds performance, performance feeds flight planning, and air law and operational procedures frame everything else. Use the current CAAB-prescribed syllabus and the Bangladesh AIP as your anchor documents, and practise numerical questions (mass and balance, fuel, wind triangle, crosswind) until they are routine. Confirm current fees, dates, pass criteria and retake rules directly with CAAB, since it publishes the operative figures and these change.

What you'll study

Common questions

About CAAB CPL Theory Exam preparation

What is the format of the CAAB CPL theory papers?

Papers are sat subject by subject across the nine knowledge areas. Most sittings are multiple-choice, but some subject sittings may use written or descriptive papers. CAAB sets the format for each sitting, so confirm the current arrangement for your subject on the authority's site before you register.

How long is each paper and how many questions are there?

CAAB determines the question count and time allowance for each subject paper, and it does not publish a single fixed figure across all sittings. Check the current examination notice or your school's exam office for the exact duration and item count for the subject you are sitting.

What mark do I need to pass?

The passing standard is set by CAAB and can differ between subjects and sittings. The authority publishes the operative pass mark in its current examination documentation. Do not rely on figures quoted by other candidates, as these are frequently out of date.

How hard is it compared with other CPL theory exams?

The depth is comparable to other ICAO-aligned CPL syllabi, but the difficulty for most candidates lies in breadth and in numerical accuracy rather than trick questions. Air law and operational procedures reward careful reading of local regulations; navigation and flight planning punish arithmetic slips. Consistent weekly study outperforms last-minute cramming.

Can I retake a failed subject, and how soon?

Retakes are permitted, but the number of attempts, the waiting period and any validity window on passed subjects are governed by CAAB rules. These details are published by the authority and are subject to change, so verify the current policy before assuming a timeline.

How long are my passes valid?

CAAB applies a validity period to theory examination passes, tied to the period within which you must complete the licence requirements. Because this can affect your whole training plan, confirm the current validity rule directly with CAAB or your flying school rather than working from older material.

In what order should I study the subjects?

Start with principles of flight and aircraft general knowledge to build the technical base, then meteorology and navigation, then flight performance and planning where those subjects combine. Air law and operational procedures are easiest once you know the aircraft and environment; communications is best practised continuously rather than studied in isolation.

What are the most common reasons candidates fail?

Weak numerical fluency in performance, mass and balance and flight planning; shallow air law knowledge based on general ICAO material rather than Bangladesh regulations; and studying subjects in isolation so that cross-subject questions feel unfamiliar. Poor time management in multiple-choice papers also costs marks.

Do I need ground school before sitting the papers?

Yes - CAAB expects evidence of approved ground training, normally through a recognised flying school, and the school usually handles examination registration. Speak to your school's examination officer early so your study plan matches the papers they will enter you for.

Where do I find the current fees and exam dates?

Fees, examination dates and application deadlines are published by the Civil Aviation Authority of Bangladesh. Neither this page nor any third-party summary should be treated as authoritative for these figures - check the CAAB website or your flying school for the current schedule.
