Air Law, Regulations and ATC Procedures for Aerodesport Activity
The regulatory ladder
Candidates must know how Brazilian aviation law is layered. The primary statute is the Código Brasileiro de Aeronáutica (Lei 7.565/1986), which sets the legal framework for aircraft registration, crew licensing and liability. Below it sit ANAC regulations (RBACs), and below those the technical standards and the AIS publications: the AIP, NOTAMs and the VFR charts. Questions often test which document governs a given situation. A trap: assuming a NOTAM can override an RBAC. It cannot; a NOTAM publishes operational information, not law.
Airspace and clearances
Understand the classes of airspace and what they mean for VFR: in controlled airspace a VFR flight needs an ATC clearance, two-way radio and, above certain levels, a transponder. Learn the difference between a clearance, an instruction and an advisory. Only a clearance authorises you to proceed; an instruction must be complied with unless safety demands otherwise, and you must advise ATC immediately if you deviate. Another frequent trap is confusing the aerodrome traffic circuit with the traffic pattern altitude published in the AIP - the published altitude prevails unless ATC states otherwise.
Aerodrome rules and documents
Know the certificates and documents carried on board for aerodesportivo operations, the validity of the pilot licence and medical certificate, and the rules on minimum equipment. Questions often ask what happens when a document expires mid-flight - the answer is that the flight may continue if it began when the documents were valid, but must not be dispatched again.
Worked rule of thumb
For VFR minimum visibility in uncontrolled airspace below 900 m AMSL, remember the "5-1500" style pair only after verifying it against the current RBAC and AIP for the specific airspace class; never quote a remembered number without checking the chart legend. In the exam, if two answers differ only by a number, the one consistent with the airspace class shown in the question stem is correct.
