GCAA CAR-66 B2 Exam

The examination uses multiple-choice questions across the twelve CAR-66 Part 66 modules listed in the syllabus. Each module is assessed separately, so you sit and pass modules individually rather than in a single combined paper. Confirm the current delivery method and sitting arrangements with the GCAA before booking.

The GCAA source material reviewed for this page does not state a question count or time limit, so we do not publish figures we cannot verify. Treat any number you see elsewhere as unconfirmed unless it comes from the GCAA directly. Check your examination booking confirmation for the official duration.

A pass mark is not stated in the source material reviewed here, so we have not published one. Passing standards can be revised, and older figures circulating online may be out of date. Verify the current pass criteria with the GCAA or your approved training organisation before you sit a module.

Retake rules, waiting periods, and any limits on attempts are not specified in the source material reviewed here. These policies can change, so confirm the current position with the GCAA when you receive your result. Plan your study so that a resit does not disrupt your overall module schedule.

The B2 syllabus is broad and technically demanding, blending mathematics and physics with electrical, electronic, and digital systems plus maintenance practices and legislation. Difficulty varies by module: calculation-heavy and avionics modules typically require the most practice. Most candidates find consistent, spaced study over several months more effective than last-minute cramming.

Start with the foundational modules: mathematics, physics, electrical fundamentals, and electronic fundamentals. Build on these with digital techniques and electronic instrument systems, then materials and hardware and maintenance practices. Add basic aerodynamics, human factors, and aviation legislation, and finish with the turbine aeroplane and helicopter system modules, which draw on everything before them.

Candidates most often lose marks through weak fundamentals in electrical and electronic theory, unfamiliarity with calculation-style questions, and shallow knowledge of legislation and maintenance practices treated as memorisation. Another frequent problem is studying systems modules before the underpinning physics and electronics are solid, which makes later material much harder to absorb.

The GCAA publishes aviation legislation, regulations, and reference material through its official website, gcaa.gov.ae. Use the authority's own publications as your primary reference for module content and regulatory requirements. This page is an independent study resource and is not affiliated with or endorsed by the GCAA.

Shift from reading to retrieval practice: answer multiple-choice questions under timed conditions, review every wrong answer against the underlying theory, and revisit weak modules rather than re-reading strong ones. Keep a short list of formulas and definitions for daily review. Confirm your exam logistics with the GCAA so nothing administrative distracts you on the day.
