Air Law and the Regulatory Framework for Brazilian ATS
The legal hierarchy
A candidate must be able to trace how a rule becomes binding in Brazil. At the top sits the Chicago Convention and its ICAO Annexes, which are standards and recommended practices (SARPs). Annex 2 (Rules of the Air), Annex 11 (Air Traffic Services), Annex 3 (Meteorology), Annex 10 (Aeronautical Telecommunications) and Annex 12 (Search and Rescue) are the core ATS documents. ICAO SARPs are not self-executing: they bind a State once incorporated into national law. In Brazil this is done through Lei 7.565/1986 (Código Brasileiro de Aeronáutica), complemented by DECEA publications - the ICA 100 series (ICA 100-12 covers airspace and ATS rules; ICA 100-37 covers ATS services) - and the RBAC regulations of ANAC for certification matters.
Traps to watch
Questions love the distinction between standard (mandatory; a State must notify a difference if it does not comply) and recommended practice (desirable). Another trap is mixing the regulator with the service provider: ANAC regulates civil aviation, DECEA provides ATS through the Comando da Aeronáutica, and CENIPA investigates accidents. Also know that an AIP amendment cycle and a NOTAM are different instruments - a NOTAM is for temporary or urgent information.
Rule of thumb
Ask: who issues, who applies, who investigates? Regulator = ANAC; provider = DECEA/Serviço de Tráfego Aéreo; investigator = CENIPA; international baseline = ICAO Annexes.
Worked example
A question states that a State may simply ignore an Annex 11 standard. Answer: no - it must either comply or file a difference with ICAO; national publication through the AIP is the normal vehicle.
