ANAC RBAC 100 Remote Pilot study guide
ANAC RBAC 100 Remote Pilot · Work through your exam, one topic at a time.
The RBAC 100 remote pilot credential is issued in Brazil by ANAC, the national civil aviation agency, to people who want to fly unmanned aircraft in the "open" category of the Brazilian unmanned aircraft rules. It is aimed at pilots flying small drones for recreation or for simple low-risk work who need to show they understand the rules, airspace, and safe operating practice before flying near people or in shared airspace. The ANAC RBAC 100 Remote Pilot study guide has 9 sections and about 3,321 words.
01Regulations and Administrative Requirements (RBAC 100, ICAO Annexes, ANAC Norms)
Brazilian remotely piloted aircraft operations are governed primarily by RBAC 100 (Regulamento Brasileiro da Aviação Civil, issued by ANAC), which classifies UAS by maximum takeoff weight (MTOW) and by the purpose/risk of the operation. Learn the weight bands and what each unlocks: the lightest band (up to 250 g) is essentially unregulated for recreational flight; the 250 g–25 kg band is the workhorse category for commercial work and requires registration when used commercially; above 25 kg and for operations beyond visual line of sight (BVLOS), above 400 ft AGL, or over people, an authorization or special approval from ANAC is required, often with a project-specific risk assessment.

Brazilian airspace is structured in the AIS/AIP Brasil publications: FIRs, control areas, TMAs, CTRs, airways, and prohibited, restricted, and danger areas . UAS operations sit inside that structure, and the controlling authority for access is DECEA , with ANAC regulating the operator side.
375 words, about 2 min03Meteorology and Its Effect on Unmanned Aircraft Operations
Meteorology for UAS is less about ceilings and visibility minima than about wind, gusts, turbulence, density altitude, precipitation, and icing . Know how to read a METAR and TAF : wind direction/speed/gusts, visibility, present weather, cloud base, temperature/dewpoint (for fog and icing risk), and QNH.
372 words, about 2 min04Aircraft Performance, Loading, and Mass-and-Balance
Performance questions test whether you can connect weight, thrust, wing loading, density altitude, and battery state to the operation you are planning. For multirotors, thrust must exceed weight with a reserve margin for maneuvering and gusts; for fixed-wing UAS, stall speed rises with wing loading and with altitude (true airspeed increases for a given indicated speed as density falls).
390 words, about 2 min05Navigation and Flight Planning for UAS
UAS navigation blends map reading, coordinate systems, GNSS behavior, and contingency planning . You must be fluent in latitude/longitude formats (degrees-minutes-seconds versus decimal degrees) because a transposed coordinate is a real accident cause, and in WGS-84 as the datum used by GNSS and most mapping products.
349 words, about 2 min06Operational Procedures, Risk Assessment, and Emergency Management
Operational procedure questions test discipline: pre-flight inspection, site survey, crew briefing, in-flight monitoring, and post-flight reporting . The risk-assessment framework you must know is the SORA -style logic used internationally and reflected in ANAC practice: identify the ground risk (who is under the flight path) and air risk (other airspace users), then apply mitigations - containment, altitude limits, buffers, observers, and procedures - until the residual risk is acceptable.
365 words, about 2 min07Human Factors and Crew Resource Management
The remote pilot sits at the end of a data link, often alone, often task-saturated by a screen. Human factors questions test situational awareness, workload management, fatigue, complacency, and communication .
359 words, about 2 min08Communications, Radio Procedures, and Data Link
UAS operations involve voice communication with ATS and data communication with the aircraft . Questions test whether you can keep them separate.
379 words, about 2 min09UAS Systems, Propulsion, and Control Links
Systems questions test the subsystems and their failure signatures : airframe, propulsion (electric motors/ESCs or combustion engines), power (batteries, BMS, fuel), flight controller and sensors (IMU, barometer, magnetometer, GNSS), payload, and the C2 link. For each, know what happens when it degrades and what the pilot sees.
