Question 1Air Law and Regulations (Regulamento Brasileiro da Aviação Civil)
Under the Brazilian Civil Aviation Regulation (RBAC) framework issued by ANAC, which document establishes the technical requirements an operator must meet to obtain an air operator certificate for commercial air transport?
- The RBAC that regulates airport slot allocation at coordinated airports
- The RBAC that governs certification and operating requirements for commercial air transport operators Correct answer.
- The RBAC that addresses aircraft registration and nationality marks only
- The RBAC that sets medical fitness standards for air traffic controllers
Explanation
ANAC publishes RBACs as the Brazilian civil aviation regulations, and the certification of commercial air transport operators is addressed by the specific RBAC on operator certification and operating requirements. That regulation contains the technical, organizational, and operational conditions an applicant must satisfy before an air operator certificate is issued.
Question 2Air Law and Regulations (Regulamento Brasileiro da Aviação Civil)
In Brazilian civil aviation, which body is the primary civil aviation authority responsible for regulating and overseeing civil aviation safety and issuing RBAC regulations?
- ANAC, the National Civil Aviation Agency Correct answer.
- DECEA, the Department of Airspace Control
- CENIPA, the aviation accident investigation center
- INFRAERO, the airport infrastructure company
Explanation
ANAC is the Brazilian federal civil aviation agency, created to regulate and supervise civil aviation activity and to issue the RBAC series of regulations. It exercises safety oversight functions such as certification, licensing, and continuing surveillance of operators.
Question 3Air Law and Regulations (Regulamento Brasileiro da Aviação Civil)
What is the primary purpose of an Air Operator Certificate (AOC) issued under Brazilian regulations?
- It grants the holder ownership rights over allocated airport slots
- It authorizes the holder to conduct specified commercial air transport operations subject to the conditions stated in the certificate and its operations specifications Correct answer.
- It licenses individual pilots to act as pilot in command
- It certifies that each individual aircraft is airworthy for a single flight
Explanation
The AOC is the formal authorization that allows an operator to perform commercial air transport, and its scope is defined by the certificate together with the associated operations specifications. It reflects the authority's determination that the operator's organization, procedures, and resources meet the applicable requirements.
Question 4Air Law and Regulations (Regulamento Brasileiro da Aviação Civil)
Which regulation series does ANAC use to publish Brazilian civil aviation regulations?
- The FAR series
- The RBAC series Correct answer.
- The ICAO Annex series
- The JAR series
Explanation
ANAC issues Brazilian Civil Aviation Regulations under the RBAC designation, which is the national regulatory series applicable to persons and organizations under Brazilian jurisdiction. ICAO Annexes, FARs, and JARs are foreign or international instruments that are not themselves Brazilian regulations.
Question 5Air Law and Regulations (Regulamento Brasileiro da Aviação Civil)
An operator holds an AOC and wishes to add a new aircraft type to its commercial operations. What is the correct regulatory approach?
- Ask the airport operator to approve the addition of the new type
- Obtain an amendment to the operations specifications from ANAC before commencing operations with the new type Correct answer.
- Rely on the pilot's type rating alone, since the AOC covers all aircraft types
- Begin operations immediately and notify ANAC within the following year
Explanation
The scope of commercial operations is defined by the AOC and its operations specifications, so adding an aircraft type requires prior amendment and demonstration of compliance with the applicable requirements. The operator must show that its programs, training, and maintenance arrangements cover the new type before it is used commercially.
Question 6Air Law and Regulations (Regulamento Brasileiro da Aviação Civil)
In the context of Brazilian civil aviation regulation, what does the term 'operations specifications' refer to?
- The maintenance schedule published by the aircraft manufacturer
- The document attached to the AOC that defines the specific authorizations, limitations, and conditions under which the operator may conduct operations Correct answer.
- The pilot's personal logbook record of flight hours
- The airline's published timetable of passenger services
Explanation
Operations specifications form part of the operator's certification and set out the particular authorizations and limitations applicable to that operator, such as authorized areas, procedures, and equipment. They translate the general regulatory requirements into operator-specific conditions.
Question 7Air Law and Regulations (Regulamento Brasileiro da Aviação Civil)
What is the general rule under Brazilian regulations regarding the carriage of dangerous goods by an operator?
- Dangerous goods may be carried only when the operator is specifically authorized and complies with the applicable dangerous goods requirements Correct answer.
- Dangerous goods may be carried freely as long as the crew is informed verbally
- Dangerous goods are prohibited in all circumstances without exception
- Dangerous goods may be carried only on non-commercial flights
Explanation
Carriage of dangerous goods requires specific authorization and adherence to the technical requirements governing classification, packing, marking, documentation, and training. Operators must also ensure that personnel involved receive appropriate dangerous goods training.
Question 8Air Law and Regulations (Regulamento Brasileiro da Aviação Civil)
An operator's manual system under Brazilian regulations typically requires which of the following?
- An operations manual and associated manuals that are approved or accepted as required and kept up to date Correct answer.
- Manuals that are kept confidential from the authority
- A single informal notebook maintained by the chief pilot
- Manuals that are revised only when the aircraft is sold
Explanation
The operator must maintain a documented manual system describing its organization, procedures, and operating policies, with the required manuals submitted for approval or acceptance. The manuals must be kept current so that flight and ground personnel work from valid instructions.
Question 9Air Law and Regulations (Regulamento Brasileiro da Aviação Civil)
Which of the following best describes the role of the RBAC covering aircraft maintenance and continuing airworthiness for Brazilian operators?
- It determines the number of cabin crew required for each route
- It governs the design of airport terminal buildings
- It sets the fares that airlines may charge passengers
- It establishes requirements for maintenance programs, organizations, and continuing airworthiness management so aircraft remain airworthy Correct answer.
Explanation
Continuing airworthiness regulations address maintenance programs, approved maintenance organizations, and the management of airworthiness records and defects. Their purpose is to ensure that aircraft continue to meet airworthiness standards throughout their service life.
Question 10Air Law and Regulations (Regulamento Brasileiro da Aviação Civil)
Under Brazilian regulations, an operator must ensure that flight crew members hold the appropriate licences and ratings. Which statement is correct?
- Licence validity is verified only once at the time of hiring
- Ratings may be issued internally by the operator without authority involvement
- A licence is unnecessary if the pilot has extensive experience
- Licences and ratings must be valid and appropriate for the aircraft and operation, and the operator must verify their validity Correct answer.
Explanation
The operator is responsible for confirming that crew members hold valid licences and ratings suitable for the aircraft type and kind of operation. This verification is a continuing obligation and is normally part of the operator's records and training program.
Question 11Air Law and Regulations (Regulamento Brasileiro da Aviação Civil)
What is the purpose of the minimum equipment list (MEL) in Brazilian operations?
- It records the minimum crew qualifications for each route
- It allows dispatch with specified equipment inoperative, subject to defined conditions and limitations Correct answer.
- It lists the minimum number of passengers required to operate a flight
- It specifies the minimum fuel that must be carried on every flight
Explanation
The MEL is derived from the master minimum equipment list and permits operation with particular items inoperative under stated conditions, while preserving an acceptable level of safety. It does not authorize operation with inoperative items that are not covered by the approved list.
Question 12Air Law and Regulations (Regulamento Brasileiro da Aviação Civil)
An operator discovers that an aircraft has a defect not covered by the MEL and not deferred under an approved procedure. What is the correct action?
- The aircraft must not be dispatched until the defect is rectified in accordance with approved maintenance procedures Correct answer.
- The defect may be deferred indefinitely without documentation
- The aircraft may be dispatched for a single ferry flight with passengers
- The aircraft may be dispatched if the captain accepts the risk in writing
Explanation
When a defect is not covered by the approved deferral provisions, the aircraft is not airworthy for dispatch and must be repaired before flight. Deferral is only permitted within the limits and conditions of the approved MEL or other authorized documents.
Question 13Air Law and Regulations (Regulamento Brasileiro da Aviação Civil)
Which statement correctly describes the applicability of RBAC regulations to foreign operators flying into Brazil?
- Foreign operators are entirely exempt from Brazilian regulations
- Foreign operators must obtain a Brazilian AOC to overfly Brazilian territory
- Foreign operators must comply with the Brazilian regulations applicable to their operations in Brazil, in addition to their State of Operator requirements Correct answer.
- Foreign operators are subject only to the regulations of their own State in all matters
Explanation
Brazil exercises sovereignty over its territory and airspace, so foreign operators must observe the Brazilian rules applicable to operations within Brazil while also meeting their own State's requirements. Overflight and landing are governed by permits and applicable bilateral arrangements rather than by issuing a Brazilian AOC.
Question 14Air Law and Regulations (Regulamento Brasileiro da Aviação Civil)
What is the main function of the Brazilian aircraft registry in the regulatory system?
- It records the nationality and ownership status of aircraft and supports the issuance of nationality and registration marks Correct answer.
- It approves airline schedules and tariffs
- It certifies the airworthiness of each aircraft type design
- It licenses maintenance engineers
Explanation
Registration establishes the aircraft's nationality and provides a public record of ownership and encumbrances, which is essential for legal and operational purposes. Airworthiness certification is a distinct function performed under separate requirements.
Question 15Air Law and Regulations (Regulamento Brasileiro da Aviação Civil)
Under the RBAC framework, which of the following is a typical obligation of the accountable manager of a certified operator?
- Approving the national aviation regulations on behalf of ANAC
- Personally piloting at least half of the operator's flights
- Ensuring that all operations are conducted in accordance with the applicable requirements and that adequate resources are provided Correct answer.
- Conducting accident investigations for the operator
Explanation
The accountable manager has corporate authority for ensuring that all activities can be financed and carried out to the required standards, and is accountable to the authority for the operator's compliance. This role is about organizational responsibility rather than flight duties or regulatory rulemaking.
Question 16Air Law and Regulations (Regulamento Brasileiro da Aviação Civil)
An operator plans to conduct a flight into an aerodrome that is not listed in its operations specifications. What must occur first?
- The operator may proceed if the aerodrome has a paved runway
- The operator may proceed if the flight is conducted at night
- The operator may proceed if the passengers consent to the destination
- The operator must obtain the necessary authorization or amendment so that the aerodrome is within its approved scope Correct answer.
Explanation
Operations specifications define where and how the operator may operate, so aerodromes outside the approved scope require authorization or an amendment before use. Runway surface, time of day, or passenger consent do not substitute for the required authorization.
Question 17Air Law and Regulations (Regulamento Brasileiro da Aviação Civil)
What is the general requirement concerning the operator's safety management arrangements under Brazilian regulations?
- The operator must establish and maintain a safety management system appropriate to its size and complexity Correct answer.
- The operator must rely solely on the captain's judgment for hazard identification
- The operator must report hazards only after an accident occurs
- The operator must outsource all safety functions to the airport operator
Explanation
Certificated operators are expected to maintain safety management arrangements that include hazard identification, risk assessment, and continuous improvement, scaled to the nature of their operations. Reactive reporting only after accidents would not meet the proactive intent of these requirements.
Question 18Air Law and Regulations (Regulamento Brasileiro da Aviação Civil)
Which of the following best describes the concept of 'commercial air transport' in Brazilian regulation?
- Any flight conducted for flight training without payment
- Any flight conducted by a private pilot for personal travel
- Any flight operated by a military organization
- The transport of passengers, cargo, or mail for remuneration or hire Correct answer.
Explanation
Commercial air transport involves the carriage of passengers, cargo, or mail for remuneration or hire, which triggers the requirement for an appropriate operator certificate. Private, military, and unpaid training flights fall outside that definition.
Question 19Air Law and Regulations (Regulamento Brasileiro da Aviação Civil)
What is the purpose of the minimum crew requirement established in the operator's certification?
- To ensure that the number and composition of crew are sufficient for the safe conduct of the planned operation Correct answer.
- To satisfy passenger preference for cabin service
- To minimize the operator's labor costs on each route
- To comply with airport slot conditions
Explanation
Minimum crew requirements are set to guarantee that sufficient qualified personnel are available for the safe operation of the aircraft and the management of emergencies. They are safety-based and are not driven by cost or service preferences.
Question 20Air Law and Regulations (Regulamento Brasileiro da Aviação Civil)
An operator's flight crew duty and rest limitations under Brazilian regulations are primarily intended to achieve which objective?
- To align crew schedules with airport slot allocations
- To standardize crew salaries across operators
- To control fatigue so that crew members remain fit to perform their duties safely Correct answer.
- To maximize the number of sectors flown per day
Explanation
Flight and duty time limitations, together with rest requirements, exist to manage fatigue and preserve crew alertness. They set maximum limits and minimum rest periods rather than targets for productivity.
Question 21Air Law and Regulations (Regulamento Brasileiro da Aviação Civil)
Under Brazilian regulations, what must an operator do when a crew member reports unfit for duty due to illness shortly before a flight?
- Remove the crew member from the flight and arrange a qualified replacement before dispatch Correct answer.
- Dispatch the flight with the affected crew member in a non-safety role only
- Allow the crew member to self-medicate and proceed
- Allow the crew member to fly if the flight is shorter than two hours
Explanation
A crew member who is unfit for duty cannot perform safety-related duties, so the operator must replace that person with a qualified crew member before the flight departs. Flight duration, self-medication, or reassignment to another safety role do not cure the unfitness.
Question 22Air Law and Regulations (Regulamento Brasileiro da Aviação Civil)
Which statement about the carriage of passengers in cargo compartments under Brazilian regulations is correct?
- Passengers may not be carried in cargo compartments that are not designed and approved for passenger occupancy Correct answer.
- Passengers may be carried in cargo compartments if seat belts are improvised
- Passengers may be carried in cargo compartments on domestic flights only
- Passengers may be carried in cargo compartments when the flight is full
Explanation
Occupancy of cargo compartments is prohibited unless the compartment is designed and approved for passenger carriage, with the necessary safety features. Improvised restraints, domestic status, or high demand do not make such carriage permissible.
Question 23Air Law and Regulations (Regulamento Brasileiro da Aviação Civil)
What is the effect of a suspension of an air operator certificate by ANAC?
- The operator may not exercise the privileges of the certificate while the suspension is in force Correct answer.
- The operator may transfer its certificate to another company for the suspension period
- The operator's aircraft automatically lose their certificates of airworthiness permanently
- The operator may continue operating at reduced frequency
Explanation
Suspension withdraws, for the period stated, the authority to exercise the privileges granted by the certificate. It does not automatically and permanently invalidate individual aircraft airworthiness certificates, and the certificate cannot be lent or transferred to another entity.
Question 24Air Law and Regulations (Regulamento Brasileiro da Aviação Civil)
Which of the following documents must generally be carried on board an aircraft engaged in international commercial air transport under Brazilian requirements?
- The aircraft certificate of registration and the certificate of airworthiness, among other specified documents Correct answer.
- Only the captain's employment contract
- Only the operator's commercial timetable
- Only the passenger manifest
Explanation
Aircraft engaged in international operations must carry the documents specified by the applicable regulations, which include the registration and airworthiness certificates together with other operational documents. The passenger manifest, timetable, and employment contract are not substitutes for these certificates.
Question 25Air Law and Regulations (Regulamento Brasileiro da Aviação Civil)
An operator intends to change its approved maintenance arrangements by contracting a new maintenance organization. What is the regulatory expectation?
- The change may be implemented and reported at the next certificate renewal
- No approval or oversight is needed because maintenance is contracted out
- The change requires only the maintenance organization's commercial agreement
- The arrangement must be acceptable to ANAC and the organization must hold the appropriate approvals for the work performed Correct answer.
Explanation
Contracted maintenance must be performed by organizations holding the appropriate approvals, and the operator remains responsible for ensuring that the arrangements satisfy the regulatory requirements and are acceptable to the authority. A commercial agreement alone does not establish the required approvals or oversight.
Question 26Air Law and Regulations (Regulamento Brasileiro da Aviação Civil)
Under the Brazilian Civil Aviation Regulation (RBAC), which document issued by ANAC authorizes an operator to conduct commercial air transport operations?
- Registration Certificate
- Certificate of Airworthiness (C of A)
- Noise Certificate
- Air Operator Certificate (AOC) Correct answer.
Explanation
The Air Operator Certificate (AOC) is the formal authorization issued by ANAC that permits an operator to conduct commercial air transport operations. It certifies that the operator meets the organizational, operational, and safety requirements set out in the applicable RBAC. Other certificates, such as the Certificate of Airworthiness, relate to the aircraft itself, not to the operator's authority to conduct commercial operations.
Question 27Air Law and Regulations (Regulamento Brasileiro da Aviação Civil)
What is the primary purpose of the RBAC requirement for an operator to maintain a quality system?
- To replace the need for ANAC inspections
- To reduce the operator's insurance premiums
- To ensure that the operator's processes comply with applicable regulations and are effective Correct answer.
- To guarantee that all flights arrive on schedule
Explanation
A quality system under the RBAC is intended to provide the operator with a systematic means of verifying that its processes and procedures comply with applicable regulations and are effective in achieving safety and operational objectives. It supports continuous improvement and corrective action. It does not guarantee schedule reliability, reduce insurance costs, or eliminate ANAC's oversight role.
Question 28Air Law and Regulations (Regulamento Brasileiro da Aviação Civil)
Which of the following is a standard condition for the issuance of an Air Operator Certificate (AOC) by ANAC?
- The operator must be a publicly traded company
- The operator must have its principal place of business in Brazil Correct answer.
- The operator must have a minimum of ten aircraft
- The operator must own at least one aircraft
Explanation
ANAC requires that an applicant for an AOC have its principal place of business in Brazil and meet the organizational and operational requirements of the applicable RBAC. Ownership of aircraft is not mandatory; operators may lease aircraft. There is no minimum fleet size or requirement to be publicly traded.
Question 29Air Law and Regulations (Regulamento Brasileiro da Aviação Civil)
Under the RBAC, what is the maximum period for which an air operator certificate may be issued before renewal is required?
- One year
- Five years Correct answer.
- Two years
- Ten years
Explanation
The RBAC provides that an Air Operator Certificate is issued for a maximum period of five years, after which it must be renewed subject to the operator continuing to meet the requirements. This periodic renewal allows ANAC to reassess the operator's compliance. Shorter or longer periods are not the standard maximum under the regulation.
Question 30Air Law and Regulations (Regulamento Brasileiro da Aviação Civil)
An operator's aircraft is due for a scheduled maintenance check, but the operator wishes to defer a non-critical item. Under the RBAC, which document must be used to defer such items?
- The Configuration Deviation List (CDL)
- The Aircraft Maintenance Manual (AMM)
- The Minimum Equipment List (MEL) Correct answer.
- The Master Minimum Equipment List (MMEL)
Explanation
The Minimum Equipment List (MEL) is the operator-specific document, approved by ANAC, that identifies items that may be deferred under specified conditions. It is derived from the Master Minimum Equipment List (MMEL) but tailored to the operator's fleet and procedures. The AMM provides maintenance instructions, the MMEL is the certification basis, and the CDL addresses external configuration deviations.
Question 31Air Law and Regulations (Regulamento Brasileiro da Aviação Civil)
During a ramp inspection, ANAC finds that a flight crew member's licence is not valid for the aircraft type being operated. What is the most likely regulatory consequence for the operator?
- The operator may be subject to enforcement action, including suspension or revocation of its AOC Correct answer.
- The operator will receive only a warning with no further action
- The aircraft will be immediately confiscated by ANAC
- The crew member will be retrained and the matter closed without operator penalty
Explanation
Operating an aircraft with a crew member who does not hold the appropriate licence and type rating is a serious violation of the RBAC. ANAC may take enforcement action against the operator, which can include suspension or revocation of the AOC, depending on the circumstances. A warning alone would not reflect the seriousness, retraining does not address the operator's responsibility, and confiscation of the aircraft is not a standard enforcement measure.
Question 32Air Law and Regulations (Regulamento Brasileiro da Aviação Civil)
An operator wants to add a new aircraft type to its fleet. What must the operator do before commencing commercial operations with the new type?
- Obtain approval from the aircraft manufacturer
- Notify ANAC after the first commercial flight
- Only update the aircraft registration
- Obtain ANAC approval by amending its operations specifications Correct answer.
Explanation
Before operating a new aircraft type commercially, the operator must obtain ANAC approval, which typically involves amending the operations specifications to include the new type. This ensures that the operator's manuals, training programs, and maintenance arrangements are appropriate for the new type. Notification after the fact, registration alone, or manufacturer approval does not satisfy the regulatory requirement.
Question 33Air Law and Regulations (Regulamento Brasileiro da Aviação Civil)
Under the RBAC, what is the required action when an operator's accountable manager ceases to meet the required qualifications?
- The operator may continue indefinitely with the current manager
- The operator must notify ANAC and appoint a qualified replacement Correct answer.
- The operator must transfer accountability to the chief pilot
- The operator must suspend all operations immediately
Explanation
The accountable manager must meet specified qualifications and have the authority to ensure that all activities are carried out to the required standards. If the accountable manager no longer meets these requirements, the operator must notify ANAC and appoint a qualified replacement. Continued operation with an unqualified manager is not permitted, immediate suspension is not automatically required, and accountability cannot simply be transferred to another role.
Question 34Air Law and Regulations (Regulamento Brasileiro da Aviação Civil)
Which of the following best describes the RBAC requirement for an operator's safety management system (SMS)?
- It must be outsourced to a third-party provider
- It must include a process for identifying hazards and managing risk Correct answer.
- It must be limited to flight operations only
- It must be approved by the aircraft manufacturer
Explanation
The RBAC requires an operator's safety management system to include a process for identifying hazards, assessing and mitigating risks, and ensuring continuous safety improvement. The SMS must be integrated into the operator's overall management system and cover all aspects of its operations, not just flight operations. It is the operator's responsibility and is not outsourced or approved by the manufacturer.
Question 35Air Law and Regulations (Regulamento Brasileiro da Aviação Civil)
An operator's flight manual contains a procedure that conflicts with an RBAC requirement. Which takes precedence?
- The more recent of the two
- The flight manual procedure
- The procedure approved by the manufacturer
- The RBAC requirement Correct answer.
Explanation
Regulations establish the minimum requirements that operators must meet. If an operator's manual contains a procedure that conflicts with an RBAC requirement, the regulation prevails and the manual must be amended to comply. The manual cannot override regulatory requirements, regardless of its date or manufacturer approval.
Question 36Air Law and Regulations (Regulamento Brasileiro da Aviação Civil)
Under the RBAC, what is the requirement for an operator to have a maintenance control system?
- It must be managed by the aircraft manufacturer
- It must be staffed exclusively by ANAC inspectors
- It must be located outside Brazil
- It must ensure that all maintenance is performed in accordance with approved standards Correct answer.
Explanation
The RBAC requires the operator to establish a maintenance control system that ensures all maintenance is performed in accordance with approved standards and that the aircraft remains airworthy. The system is the operator's responsibility and must be integrated into its organization. It is not managed by the manufacturer, does not need to be outside Brazil, and is not staffed by ANAC inspectors.
Question 37Air Law and Regulations (Regulamento Brasileiro da Aviação Civil)
Which of the following is a required element of an operator's training program under the RBAC?
- Training provided exclusively by the manufacturer
- Training that is optional for senior crew
- Initial and recurrent training for crew members Correct answer.
- Training only for new crew members
Explanation
The RBAC requires operators to provide initial and recurrent training to crew members to ensure they remain competent and current. Recurrent training is essential for maintaining proficiency and updating knowledge of procedures and regulations. Training limited to new crew, provided exclusively by the manufacturer, or optional for senior crew would not meet the requirement.
Question 38Air Law and Regulations (Regulamento Brasileiro da Aviação Civil)
An operator's aircraft is involved in an accident. Under the RBAC, what is the operator's immediate obligation regarding notification?
- Wait for ANAC to contact the operator
- Notify only the insurance company
- Notify the manufacturer first
- Notify ANAC without delay Correct answer.
Explanation
The RBAC requires the operator to notify ANAC without delay of any accident or serious incident involving its aircraft. This notification enables ANAC to initiate its investigation and oversight functions. Informing only the insurance company, waiting for ANAC to make contact, or notifying the manufacturer first does not satisfy the regulatory obligation.
Question 39Air Law and Regulations (Regulamento Brasileiro da Aviação Civil)
In the context of the RBAC, what is the primary responsibility of the pilot-in-command regarding the aircraft's documents?
- Delegate the responsibility to the co-pilot
- Ensure that the documents are filed at the operator's headquarters
- Ensure that the required documents are on board and valid Correct answer.
- Ensure that the documents are translated into English
Explanation
The pilot-in-command is responsible for ensuring that all required documents, such as the certificate of registration, certificate of airworthiness, and crew licences, are on board the aircraft and valid for the flight. This responsibility cannot be delegated. Filing documents at headquarters, delegating to the co-pilot, or translating documents does not meet the requirement.
Question 40Air Law and Regulations (Regulamento Brasileiro da Aviação Civil)
Under the RBAC, what is the maximum period for which an operator may defer maintenance items under the MEL without an extension?
- A fixed period of 30 days for all items
- Indefinitely, provided the item is not critical
- A fixed period of 10 days for all items
- As specified in the approved MEL for each item Correct answer.
Explanation
The MEL specifies, for each item, the maximum deferral period, which may vary depending on the item's criticality and the operator's approved procedures. There is no single fixed period for all items. Deferral beyond the specified period requires an extension approved by ANAC. Indefinite deferral is not permitted.
Question 41Aircraft General Knowledge and Principles of Flight
In a piston engine, what is the primary function of the carburettor?
- To meter fuel and mix it with air in the correct proportion Correct answer.
- To pressurise the fuel line before the injector nozzles
- To ignite the fuel-air mixture at the correct moment
- To cool the induction air before it enters the cylinders
Explanation
The carburettor delivers fuel into the airstream and meters it so that a combustible mixture of the desired ratio reaches the cylinders. Mixture strength must change with throttle setting and altitude to keep combustion efficient. Ignition and fuel pressurisation are handled by other systems.
Question 42Aircraft General Knowledge and Principles of Flight
Which control surface produces the primary rolling moment about the longitudinal axis?
- The flaps
- The elevators
- The ailerons Correct answer.
- The rudder
Explanation
Ailerons move in opposition, increasing lift on one wing and decreasing it on the other, which generates a rolling moment about the longitudinal axis. The rudder produces yaw about the vertical axis and the elevators produce pitch about the lateral axis. Flaps mainly increase lift and drag.
Question 43Aircraft General Knowledge and Principles of Flight
What happens to the indicated airspeed of an aircraft as it climbs at a constant true airspeed?
- It fluctuates randomly
- It increases
- It remains constant
- It decreases Correct answer.
Explanation
Indicated airspeed depends on dynamic pressure, which falls as air density decreases with altitude. At a constant true airspeed the dynamic pressure and therefore the indicated airspeed become lower as height increases. This is why true airspeed is always higher than indicated airspeed at altitude.
Question 44Aircraft General Knowledge and Principles of Flight
Which atmospheric layer contains most of the water vapour and virtually all weather phenomena?
- The thermosphere
- The mesosphere
- The stratosphere
- The troposphere Correct answer.
Explanation
The troposphere is the lowest layer and holds most of the atmosphere's water vapour, so clouds and weather form there. Temperature generally decreases with height within it. The layers above are drier and largely free of significant weather.
Question 45Aircraft General Knowledge and Principles of Flight
What is the purpose of dihedral in a wing?
- To increase the maximum lift coefficient
- To increase the stalling angle of attack
- To provide lateral stability in a sideslip Correct answer.
- To reduce the induced drag at high speed
Explanation
With dihedral, a sideslip causes the lower wing to meet the airflow at a higher effective angle of attack than the raised wing. The resulting lift difference produces a rolling moment that tends to level the wings, giving lateral stability. Dihedral therefore acts as a self-righting feature about the longitudinal axis.
Question 46Aircraft General Knowledge and Principles of Flight
In a four-stroke piston engine, during which stroke is the intake valve normally open?
- The power stroke
- The compression stroke
- The exhaust stroke
- The induction stroke Correct answer.
Explanation
The induction stroke draws the fuel-air mixture into the cylinder through the open intake valve as the piston moves down. The intake valve then closes for compression and remains shut until the cycle repeats. The exhaust valve opens for the exhaust stroke.
Question 47Aircraft General Knowledge and Principles of Flight
What is the effect of lowering flaps on the approach to landing?
- Lower drag and a reduced rate of descent
- Lower stalling speed and a steeper approach angle Correct answer.
- Higher stalling speed and a longer landing roll
- Higher stalling speed and a shallower approach angle
Explanation
Flaps increase camber and wing area, raising the maximum lift coefficient and lowering the stalling speed. The added drag allows a steeper approach angle without an increase in speed. The pilot must allow for a higher nose attitude and possible go-around limitations.
Question 48Aircraft General Knowledge and Principles of Flight
Which instrument is directly connected to the static pressure source only?
- The airspeed indicator
- The vertical speed indicator
- The turn coordinator
- The altimeter Correct answer.
Explanation
The altimeter responds only to changes in static pressure, which it converts into an altitude reading. The airspeed indicator needs both pitot and static pressure, and the vertical speed indicator uses static pressure changes over time. The turn coordinator is a gyroscopic instrument and does not use the static source.
Question 49Aircraft General Knowledge and Principles of Flight
An aircraft in a steady level turn at 60 degrees of bank experiences a load factor of approximately:
- 3.0
- 2.0 Correct answer.
- 1.4
- 1.15
Explanation
Load factor in a level turn equals one divided by the cosine of the bank angle. The cosine of 60 degrees is 0.5, so the load factor is 2.0. This doubles the apparent weight and raises the stall speed by about 41 per cent.
Question 50Aircraft General Knowledge and Principles of Flight
An aircraft stalls at 50 knots in level flight. What is its approximate stall speed in a 60-degree banked level turn?
- 58 knots
- 100 knots
- 71 knots Correct answer.
- 87 knots
Explanation
Stall speed increases with the square root of the load factor. At 60 degrees of bank the load factor is 2.0, whose square root is about 1.41. Multiplying 50 knots by 1.41 gives approximately 71 knots.
