Air Law and ATC Procedures
What this domain tests
Air Law and ATC Procedures covers the Chicago Convention and its Annexes, the Mauritius Civil Aviation Act and MCAR Parts, licensing and documentation, rules of the air, and ATS clearance and readback discipline. Expect questions that mix ICAO standard wording with Mauritius publication practice.
Core rules
- Sovereignty: each State has complete and exclusive sovereignty over its airspace (Chicago Art. 1); over the high seas, Annex 2 rules apply without exception.
- Documents: for international flight carry Certificate of Registration, Certificate of Airworthiness, licences, journey log, operations manual, MEL and, where required, radio licence and passenger manifest.
- Cruising levels follow the semicircular rule by magnetic track: 000-179 degrees odd levels, 180-359 degrees even levels; ATC may assign otherwise.
- Clearances: read back route, level, heading, speed, frequency and any hold; if unsure, request clarification rather than assume.
Worked example
You plan a magnetic track of 075 degrees at FL 240. FL 240 is an even level, so it conflicts with the semicircular rule. Request FL 230 or FL 250. If ATC issues FL 240 for traffic, that is legal because the clearance overrides the table, but it must be read back.
Traps
Confusing transition altitude with transition level: the transition level is the first available level above the transition altitude published in the AIP. Do not assume an airway clearance includes a level change. Annex 2 does not authorise flight over another State without permission.
Key exam habits
Learn which MCAR Part covers licensing (Part 61), operations (Parts 91/121/135) and aerodromes (Part 139); questions often ask only the Part number.
