Aviation Regulatory Framework and ANAC Requirements
The structure of the framework
Brazil's civil aviation regime is built on a hierarchy: the federal law that created ANAC and the national civil aviation policy sits at the top; below it come ANAC resolutions (resoluções) and normative instructions (instruções normativas), which carry the operative detail; and below those sit supplementary documents such as IS (Instrução Suplementar) and approved manuals. Treat the Brazilian Special Civil Aviation Regulation (RBAC) numbering as the working map: RBAC 61 for licences, 91 for general operating rules, 121/135 for commercial transport, 43/145 for maintenance, 141 for training organisations. A frequent trap is confusing the regulator with the accident investigator: ANAC regulates and certifies, while CENIPA investigates accidents and incidents, and the two report through different channels. Another trap is jurisdiction - questions often test whether an ANAC rule, a state rule, or an airport operator rule governs a given situation.
Reading a rule like an examiner
Questions in this domain reward precision about applicability, effective dates, and the distinction between standards (mandatory) and guidance (advisory). When a scenario describes a foreign operator flying into Brazil, the correct frame is usually the Chicago Convention plus the applicable ANAC rule for foreign operators, not the full domestic rule set. When a scenario describes a Brazilian operator abroad, the flag-state rule generally follows the aircraft.
Rule of thumb
Ask three questions in order: who is the operator, where is the aircraft, and what kind of operation is it? The answer pair (operator nationality, operation type) selects the rule set before you evaluate the facts. Worked example: a Brazilian-registered private aircraft flown by its owner to another South American state is governed by RBAC 91 for the flight and by the destination state's overflight and landing requirements for entry; it does not become a commercial operation merely because fuel was sold to a passenger.
