Air Law and ANAC Regulations (RBAC) for Commercial Helicopter Operations
The regulatory framework
Brazilian civil aviation is governed by the Lei do Aeronauta and the Código Brasileiro de Aeronáutica, implemented operationally through the Regulamentos Brasileiros da Aviação Civil (RBAC). For a commercial helicopter pilot, the key documents are RBAC 61 (licences, ratings, recency, medical validity), RBAC 91 (general operating and flight rules), RBAC 135 (commercial transport operations) and the RBAC 91 subparts covering helicopter-specific limits. Learn which regulation answers which question: a question about minimum visibility for a VFR helicopter flight belongs to RBAC 91, while one about the validity of your CPL(H) belongs to RBAC 61.
Concepts you must know
Know the privileges and limits of the CPL(H): you may act as PIC in commercial operations and carry passengers for hire, but only on aircraft for which you hold the appropriate type rating and only when recent and medically fit. Understand recency (recent flight experience), the difference between the licence, the type rating and the medical certificate, and the conditions under which a flight may be refused or must be terminated. Learn the rules on documents carried on board, maintenance release, and the pilot-in-command's final authority over the flight.
Traps in questions
Questions love to swap validity periods, altitudes and minima. Do not confuse the licence validity with the medical certificate validity, and remember that medical validity often shortens with age. Watch for options that quote a rule from fixed-wing operations applied to helicopters. Another classic trap is the word "may" versus "shall": many RBAC requirements are mandatory, not advisory.
Worked example
If a question asks whether a commercial helicopter flight may depart when the destination forecast is below VFR minima, apply the rule of thumb: the flight must be able to be conducted under VFR at all times, and forecast conditions at destination and alternate must allow a VFR arrival. When in doubt, the conservative answer that preserves legal compliance is usually correct.
