Key Facts: BR-ANAC-IFR Exam

Administered by Fundação Getulio Vargas (FGV) on behalf of ANAC across nationwide computerized test centers in Brazil.

The theoretical examination consists of 5 individual papers (20 questions each): Air Law / Regulations, Aircraft Technical Knowledge, Meteorology, Air Navigation, and Operational Procedures / IFR Flight Planning.

Candidates must achieve a minimum score of 70% (14 out of 20) on each individual paper to pass the examination.

Requires ground school instruction approval (CIAC) or meeting pre-requisite flight experience under RBAC 61 for Instrument Rating candidates.

Questions test knowledge of Brazilian airspace classifications, RBAC 91 operational rules for IFR, instrument approach charts (IAC), enroute low/high altitude charts, VOR/NDB/ILS/GNSS navigation, and instrument flight rules emergency protocols.

Note: Official ANAC examinations in Brazil are conducted in Portuguese. This question bank serves as an English-language study adaptation to help candidates master IFR concepts and technical aviation terminology.

This bank provides 100 English-language practice questions adapted for the official ANAC Instrument Flight Rules (IFR) theoretical exam in Brazil (Habilitação de Voo por Instrumentos - IFRA/IFRP), covering regulations (RBAC 61/91), instrument navigation, approach procedures, aviation meteorology, and flight instruments.

Sample BR-ANAC-IFR Practice Questions

Try these sample questions to review concepts for the BR-ANAC-IFR exam. Each question includes a detailed explanation. Start the interactive quiz above for the full 100+ question experience with AI tutoring.

1Under RBAC 91, what is the minimum fuel reserve required for an airplane operating under IFR to a destination where an alternate aerodrome is required?
A.Fuel to fly to the destination, then to the alternate, plus 45 minutes at normal cruising speed
B.Fuel to fly to the destination, then to the alternate, plus 30 minutes at normal cruising speed
C.Fuel to fly to the destination, plus 45 minutes at normal cruising speed without alternate fuel
D.Fuel to fly to the destination, then to the alternate, plus 15 minutes at holding speed
Explanation: Under RBAC 91.167 for airplane operations under IFR, when an alternate aerodrome is required, the aircraft must carry sufficient fuel to complete the flight to the intended destination, fly from the destination to the alternate aerodrome, and thereafter fly for 45 minutes at normal cruising speed.
2According to RBAC 61, how long is an ANAC Instrument Rating (IFR) theoretical examination result valid for after passing?
A.24 months
B.12 months
C.36 months
D.Indefinitely without expiration
Explanation: Under ANAC RBAC 61 regulations, theoretical examination results (Aprovado em Exame Teórico) for instrument ratings remain valid for 24 months from the date of completion to perform the practical flight test.
3Under RBAC 91, what instrument flight experience is required within the preceding 6 months to maintain IFR recency as pilot-in-command?
A.At least 6 instrument approaches, holding procedures, and intercepting/tracking courses in actual or simulated IFR conditions
B.At least 3 instrument approaches and 5 hours of VFR cross-country flight time
C.At least 10 instrument approaches in an approved flight simulator with no holding requirement
D.At least 1 hour of night flying and 3 visual landings at controlled aerodromes
Explanation: To maintain recency to act as pilot-in-command under IFR (RBAC 91), the pilot must have logged within the preceding 6 calendar months at least 6 instrument approaches, holding procedures and tasks, and intercepting and tracking courses through navigation systems.
4What is the standard vertical separation applied between IFR aircraft flying below FL 290 in Brazilian controlled airspace?
A.1,000 feet
B.500 feet
C.2,000 feet
D.1,500 feet
Explanation: In accordance with Brazilian airspace regulations (ICA 100-12 / DECEA standards aligned with ICAO), standard vertical separation between IFR aircraft operating below FL 290 is 1,000 feet.
5Which condition requires an pilot to file a destination alternate aerodrome on an IFR flight plan under standard RBAC 91 rules?
A.When the weather report/forecast for the destination aerodrome 1 hour before to 1 hour after ETA indicates ceiling below 2,000 ft or visibility below 5 km (3 SM)
B.Whenever the flight distance exceeds 100 nautical miles regardless of weather conditions
C.Only when the destination airport lacks an operational VOR approach procedure
D.Only when flying in Class G uncontrolled airspace during night hours
Explanation: Under standard RBAC 91 IFR flight planning rules (1-2-3 rule equivalent), an alternate aerodrome is required unless weather forecasts for destination from 1 hour before to 1 hour after estimated time of arrival indicate a ceiling of at least 2,000 ft above aerodrome elevation and visibility of at least 5 km (3 SM).
6What does the abbreviation 'MEA' represent on an IFR Enroute Low Altitude Chart?
A.Minimum Enroute Altitude
B.Maximum Exempt Altitude
C.Minimum Obstacle Altitude
D.Mandatory Entry Altitude
Explanation: MEA stands for Minimum Enroute Altitude. It is the lowest published altitude between radio navigation fixes that ensures acceptable navigation signal coverage and meets obstacle clearance requirements along the airway.
7Under RBAC 91, if two-way radio communication is lost while flying under IFR in IMC, what route should the pilot follow according to standard lost communications procedures?
A.Assigned route, Vectored route, Expected route, or Filed route (in that order of priority)
B.Directly to the destination airport using the shortest GPS track immediately
C.Fly to the nearest VFR airport and land immediately regardless of terrain or weather
D.Turn 90 degrees left and climb to maximum altitude while transmitting Mayday on 121.5 MHz
Explanation: Under standard IFR lost communication procedures (AVE-F rule), the route to follow in IMC is: (1) Assigned route in last ATC clearance received, (2) Vector route if being radar vectored, (3) Expected route ATC advised may be expected, or (4) Filed route in the flight plan.
8When lost radio communication occurs in IMC, what altitude should an IFR pilot maintain among Assigned, Minimum (MEA), and Expected altitudes?
A.The HIGHEST of the Assigned altitude, Minimum altitude (MEA/MOCA), or Expected altitude in the ATC clearance
B.The LOWEST of the Assigned, Minimum, or Expected altitudes to stay below icing layers
C.Always maintain FL 100 regardless of sector MEA or clearance
D.Climb immediately to the aircraft maximum certified service ceiling
Explanation: During lost communication in IMC (MEA rule), the pilot must fly at the highest altitude among: (1) the Assigned altitude in the last clearance, (2) the Minimum altitude for IFR operations (MEA/MOCA), or (3) the Expected altitude ATC advised to expect in a further clearance.
9What is the non-precision approach weather minimum requirement for listing an airport as an IFR destination alternate under RBAC 91 standard rules?
A.Ceiling 800 feet and visibility 3 km (or 2 SM) at estimated time of arrival
B.Ceiling 600 feet and visibility 2 km (or 1.5 SM) at estimated time of arrival
C.Ceiling 1,000 feet and visibility 5 km (or 3 SM) at estimated time of arrival
D.Ceiling 400 feet and visibility 1 km at estimated time of arrival
Explanation: Standard alternate minimums under RBAC 91 for an aerodrome with a non-precision approach require a forecast ceiling of at least 800 feet and visibility of at least 3 km (2 SM) at the estimated time of arrival.
10What are the standard alternate aerodrome weather minimums under RBAC 91 for an aerodrome served by a Precision Approach (such as ILS CAT I)?
A.Ceiling 600 feet and visibility 2 km (or 1.5 SM)
B.Ceiling 800 feet and visibility 3 km (or 2 SM)
C.Ceiling 400 feet and visibility 1.2 km
D.Ceiling 200 feet and visibility 800 meters
Explanation: Standard alternate minimums under RBAC 91 for an aerodrome with a precision approach procedure require a forecast ceiling of at least 600 feet and visibility of at least 2 km (1.5 SM) at the estimated time of arrival.
