Brazilian Civil Aviation Regulations (RBAC) and Operational Rules
Core concepts
RBAC questions test the Brazilian regulatory framework administered by ANAC. The candidate should understand the structure of RBAC (Brazilian Civil Aviation Regulation) and how it maps to ICAO Annexes and, where applicable, to FAA/EASA equivalents. Know the operational rules for commercial air transport, crew licensing and duty limits, and the requirements for an operator's certificate. Understand the role of the flight engineer as a required crew member and the conditions under which the position may be required or substituted. Know the rules on dispatch, fuel, weather minima, and the MEL. Also know the reporting obligations for accidents and incidents.
Traps in questions
A frequent trap is applying a foreign rule (FAR/EASA) directly when the question asks for the Brazilian requirement. Another is confusing the operator's manual with the regulation - the manual must comply with the RBAC, but the RBAC is the authority. Watch for questions about who may declare an emergency and the commander's authority.
Worked example / rule of thumb
When a question cites a specific RBAC number, verify whether it addresses licensing, operations, or airworthiness before answering. Rule of thumb: the commander has final authority over the aircraft; regulations set the floor, not the ceiling.
