Air Law and ATC Procedures (Mozambique IACM PPL)
Air law questions test precise recall of rules, not general airmanship. Anchor your revision on the structure of Mozambican regulation: the IACM (Instituto de Aviação Civil de Moçambique) is the civil aviation authority, and national rules are built on ICAO Annexes and SARPs. Know the hierarchy: the Chicago Convention and its Annexes, then the national aviation law and its regulations, then AIP Mozambique and NOTAMs. Candidates must understand aircraft nationality and registration marks, certificate of airworthiness validity, crew licensing privileges and recency, rules of the air (right-of-way, cruising levels, VFR minima, lights and signals), and the documents that must be carried on board.
Traps to expect: confusing "shall" with "should"; mixing up VFR meteorological minima for controlled versus uncontrolled airspace; mis-stating who has right-of-way (the lower aircraft does not always give way - the aircraft being overtaken gives way, and landing aircraft have priority over others); and forgetting that a clearance is a limit, not an instruction to fly exactly to it. Questions on ATC phraseology and readback requirements reward the candidate who knows which items must be read back.
Rule of thumb for right-of-way: converging at the same level, the aircraft with the other on its right gives way; head-on, both turn right; overtaking, the overtaker keeps clear. Worked example: two aircraft converge at the same level, one heading north and one heading east. The eastbound aircraft has the northbound aircraft on its right, so the eastbound aircraft gives way. Apply the rule in that order (converging, head-on, overtaking) and you will rarely err.
