About this exam

The Air Law knowledge test is one component of the Nigeria Civil Aviation Authority (NCAA) Commercial Pilot Licence (CPL) licensing pathway. It assesses whether a candidate understands the regulatory framework that governs civil aviation in Nigeria, including the Civil Aviation Act, the Nigeria Civil Aviation Regulations (Nig. CARs), and the advisory circulars that apply to commercial flight operations. The syllabus and detailed requirements for the test are published in Advisory Circular NCAA-AC-PEL 018, available under Personnel Licensing Advisory Circulars on the NCAA website. Candidates typically include student pilots progressing toward a CPL, as well as licence holders seeking to add ratings or convert foreign licences. The test is multiple choice and is delivered at the NCAA headquarters in Abuja or at the regional offices in Lagos, Kaduna, and Enugu. A passing grade is 75%, and results remain valid for 24 calendar months from the date of issuance. Preparation should centre on the current Nig. CARs and the relevant advisory circulars, supplemented by structured ground instruction from an authorised instructor. This independent study guide is designed to help you organise that preparation, understand the test format, and avoid common pitfalls.

Common questions

About NCAA CPL Air Law Exam preparation

What is the format of the NCAA CPL Air Law knowledge test?

The test is multiple choice. The source does not specify the number of questions or the time allowed, so check with the NCAA or your training organisation. The passing grade is 75%, and results are valid for 24 calendar months from the date of issuance.

Where can I take the knowledge test?

Applications to take NCAA knowledge tests can be submitted at the Authority’s headquarters in Abuja and at the regional offices in Lagos, Kaduna, and Enugu. Confirm current scheduling and any appointment requirements with the relevant office before travelling.

How hard is the Air Law test and what should I study first?

Difficulty depends on your familiarity with Nigerian regulations. Start with the syllabus in NCAA-AC-PEL 018, then study the Civil Aviation Act and the current Nig. CARs. Air Law rewards precise recall of definitions, privileges, and notification requirements, so build a structured revision schedule.

What happens if I fail? Can I retake the test?

Yes. Applicants who fail a knowledge test can apply to retake it after presenting evidence of having received additional instruction from an Authorised Instructor in the areas of deficiencies. Plan for this by keeping a record of your weak areas and arranging remedial ground training promptly.

How long is my test result valid?

Knowledge test results are valid for 24 calendar months from the date of issuance. If you do not complete the associated licensing requirements within that period, you may need to retake the test. Track your expiry date against your practical training timeline.

What is the most common reason candidates fail Air Law?

A frequent cause is relying on outdated or foreign regulations instead of the current Nigerian rules. The Nig. CARs and advisory circulars are revised, so always study the current versions. Another common issue is misreading questions that hinge on precise time limits or notification periods.

Do I need ground instruction before sitting the test?

The source does not mandate a specific ground course before the initial test, but remedial instruction is required after a failure. Most candidates benefit from structured ground school covering the NCAA-AC-PEL 018 syllabus. Confirm any prerequisites with your approved training organisation.

Can I use foreign air law study material?

Use it only as background. The NCAA test is based on Nigerian legislation and regulations, including the Civil Aviation Act and Nig. CARs. Questions may test provisions that differ from ICAO Annexes or other states’ rules, so prioritise official Nigerian documents.

How should I plan my study order for Air Law?

Begin with the Civil Aviation Act to understand the NCAA’s powers, then move to the Nig. CARs parts relevant to commercial operations, and finish with advisory circulars such as NCAA-AC-PEL 018. Regular self-testing against the syllabus helps identify gaps before the exam.
