Air Law and ATC Procedures
Core concepts
Air law questions test your knowledge of the regulatory framework: ICAO Annexes and how they map onto national rules, aircraft registration and nationality marks, certificates of airworthiness and maintenance release, crew licensing and recency, rules of the air (right-of-way, cruising levels, VMC minima, low flying), and ATC clearances, separation and readback requirements. Know the difference between Standards (binding) and Recommended Practices, and between a clearance and an instruction.
Traps
Questions love edge cases: who has right-of-way when two aircraft of the same category converge; whether an overtaking aircraft passes on the right; what a clearance limit means versus a clearance expiry; when a pilot may deviate from a clearance (only for safety, with prompt notification). Watch for confusion between semi-circular cruising levels by magnetic track and quadrantal rules. Also be precise about airspace classes and the services and clearances each provides.
Worked example
Two aircraft converge head-on at the same level. Rule of thumb: both turn right. If one is overtaking another, the overtaking aircraft keeps clear, altering heading to the right. If a converging aircraft has the other on its right, it gives way. For cruising levels, use the semi-circular rule: tracks 000-179 degrees use odd thousands (or FLs), 180-359 use even thousands, adjusted for the table in force.
Exam technique
Read the exact wording: "shall" versus "should", "may" versus "must". Eliminate answers that add a condition not in the rule.
