ANAC IBAV study guide
ANAC IBAV · Work through your exam, one topic at a time.
The IBAV (Instrumento Básico de Avaliação de Voos) is a knowledge assessment used within the Brazilian civil aviation training system, administered under the framework of the Agência Nacional de Aviação Civil (ANAC). It is aimed at student pilots and candidates who need to demonstrate a foundation in the theoretical subjects that underpin flight training before or alongside practical instruction. The ANAC IBAV study guide has 7 sections and about 1,792 words.
01Air Law and Regulations (RBAC)
Brazilian civil aviation is governed by the Regulamento Brasileiro da Aviação Civil (RBAC), issued by ANAC under Lei 7.565 (Código Brasileiro de Aeronáutica). Learn the hierarchy: the CBA is law, RBACs are regulations, and IS (Instruções Suplementares) and AC-like guidance explain compliance.
279 words, about 1 min02Aircraft General Knowledge and Principles of Flight
Understand the four forces, the lift equation (L = ½ρV²SCL), angle of attack vs pitch attitude, and the lift curve including critical angle and stall. Study the induced-drag relationship (Di ∝ CL²/(πAe)), parasite drag, and total drag curve with L/D max at best glide.
267 words, about 1 min03Flight Performance and Planning
Performance divides into take-off, climb, cruise, descent, landing, and mass-and-balance. Learn definitions: take-off distance to 35 ft, landing distance from 50 ft, accelerate-stop distance, and the effect of density altitude.
284 words, about 1 min04Human Performance and Limitations
Study hypoxia (hypoxic, hypemic, stagnant, histotoxic), time of useful consciousness, hyperventilation, and the effects of altitude. Learn spatial disorientation and sensory illusions: somatogravic, somatogyral, leans, black-hole approach, and vestibular vs visual cues.
236 words, about 1 min05Meteorology
Understand the atmosphere: ISA, lapse rates, pressure and altimetry, and QNH/QFE/QNE. Learn cloud types and formation, stability, and the difference between stable and unstable air.
259 words, about 1 min06Navigation
Study the Earth's coordinate system, latitude and longitude, and great circles vs rhumb lines. Learn chart projections: Mercator, Lambert conformal conic, and their properties.
254 words, about 1 min07Operational Procedures and Radiotelephony
Learn standard phraseology, call signs, and the readback requirement for clearances. Study ATC clearances, position reporting, and the standard circuit.
