Question 1General operational requirements, definitions and documentation

Under ICAO Annex 6, an operator's operations manual must be approved by which authority before it may be used for commercial air transport?

  1. The State of Design of the aircraft type
  2. The State of the Operator Correct answer.
  3. The State of the Aerodrome of departure
  4. The State of Registry of each aircraft

Explanation

Annex 6 Part I requires the operations manual to be approved by the State of the Operator, which is the State where the operator's principal place of business is located (or where the operator is permanently resident). That State issues the AOC and is responsible for continued oversight, so it also approves the manual and its amendments.

Question 2General operational requirements, definitions and documentation

In operations manual terminology, what does the abbreviation MEL refer to?

  1. A record of maintenance tasks completed during the last overnight check
  2. A list of items that may be inoperative while the aircraft is dispatched under defined conditions Correct answer.
  3. A schedule of maximum engine life limits set by the manufacturer
  4. A register of engineering delays reported to the authority each month

Explanation

The Minimum Equipment List specifies equipment that may be inoperative at dispatch, subject to stated operating and maintenance conditions, rectification intervals and any associated limitations. It is derived from the Master Minimum Equipment List approved for the type and is tailored to the individual operator's fleet and equipment.

Question 3General operational requirements, definitions and documentation

Which document normally accompanies the flight and contains the sector-by-sector record of defects, servicing and certification of release to service?

  1. The mass and balance sheet
  2. The notification of pilot-in-command status
  3. The operations manual Part A
  4. The technical log Correct answer.

Explanation

The technical log travels with the aircraft and records defects, deferred items, servicing and the certificate of release to service for each flight. It forms the link between the flight crew and the maintenance organisation.

Question 4General operational requirements, definitions and documentation

What is the standard definition of the term 'flight time' for a heavier-than-air aircraft in commercial air transport?

  1. Total time from the moment the aircraft first moves under its own power for take-off until it comes to rest at the end of the flight Correct answer.
  2. Total time from brake release to touchdown only
  3. Total time from engine start until engine shutdown at the parking position
  4. Total time during which the aircraft is airborne between lift-off and touchdown

Explanation

Flight time begins when the aircraft first moves under its own power for the purpose of taking off and ends when it comes to rest at the end of the flight. This is the definition used for logging and for flight and duty time limitations.

Question 5General operational requirements, definitions and documentation

Which of the following best describes the purpose of the operations manual Part B?

  1. It contains information and instructions relating to the aircraft type, its limitations and normal and emergency procedures Correct answer.
  2. It contains the operator's organisation structure and safety management responsibilities
  3. It contains the operator's training syllabi and checking programmes
  4. It contains route and aerodrome instructions and area-specific operating information

Explanation

Part B of the operations manual covers the aircraft type: limitations, normal, abnormal and emergency procedures and performance information relevant to that type. Organisation and duties appear in Part A, while route and aerodrome information appears in Part C and training in Part D.

Question 6General operational requirements, definitions and documentation

An operator wishes to change a procedure in the operations manual that affects aircraft performance limitations. What is the required action?

  1. Obtain approval of the amendment from the State of the Operator before it is used Correct answer.
  2. Introduce the amendment immediately and notify the authority within 30 days
  3. Adopt the amendment once the pilot-in-command has signed the manual
  4. Apply the amendment after approval by the aircraft manufacturer only

Explanation

Amendments to approved parts of the operations manual, including those affecting limitations and performance, must be approved by the State of the Operator before use. Unapproved changes to approved content would invalidate the basis on which the AOC was issued.

Question 7General operational requirements, definitions and documentation

What is the status of a 'company instruction' or company procedure that is more restrictive than the State regulation?

  1. It must be complied with, because the operator may impose stricter requirements than the minimum regulation Correct answer.
  2. It applies only to captains with fewer than 500 hours on type
  3. It becomes mandatory only after the authority issues it as an airworthiness directive
  4. It has no legal effect and may be disregarded when convenient

Explanation

Operators routinely set standards more conservative than the regulatory minimum, and crews are required to follow the company's published procedures. The regulation provides the minimum; the operations manual defines what the crew must actually do.

Question 8General operational requirements, definitions and documentation

Which of the following items must be carried on board as part of the aircraft documents for an international commercial flight?

  1. The certificate of registration, the certificate of airworthiness and the crew licences Correct answer.
  2. The company's financial statements and insurance policy for ground vehicles
  3. The operator's full maintenance programme and hangar planning records
  4. The complete maintenance history since the aircraft was manufactured

Explanation

Annex 6 requires the certificate of registration, certificate of airworthiness, licences of crew members, journey log, operations manual and other specified documents to be carried on board. These are the documents needed to demonstrate the aircraft's and crew's lawful status during a flight.

Question 9General operational requirements, definitions and documentation

How is 'duty period' defined for flight crew under flight and duty time limitations?

  1. A period which starts when a crew member is required to report for duty and ends when the crew member is free from all duties Correct answer.
  2. The interval between two consecutive rest periods at the home base
  3. The time spent in the aircraft from boarding to disembarkation
  4. The period between successive take-offs performed by the same crew member

Explanation

A duty period begins when the crew member is required by the operator to report, including any reporting time before flight, and ends when the crew member is free of all duties. Duty period therefore includes flight time, positioning, ground duties and any required post-flight activity.

Question 10General operational requirements, definitions and documentation

A commander signs the aircraft technical log before departure. What does this signature principally certify?

  1. That the fuel load matches the flight plan exactly
  2. That all passengers have been briefed on emergency equipment
  3. That the aircraft has been washed and cleaned to company standard
  4. That the aircraft is airworthy and that defects have been entered and, where applicable, deferred in accordance with the MEL Correct answer.

Explanation

The commander's acceptance certifies that the aircraft is airworthy for the intended flight and that any known defects have been recorded and handled in accordance with the MEL or deferred items list. It is the operational link between maintenance status and dispatch.

Question 11General operational requirements, definitions and documentation

Which term describes the State that has issued the Air Operator Certificate to the operator?

  1. The State of the Operator Correct answer.
  2. The State of Manufacture
  3. The State of Occurrence
  4. The State of Registry

Explanation

The State of the Operator is the State in which the operator's principal place of business is located, or if the operator has no such place, the operator's permanent residence. It issues the AOC and exercises safety oversight of the operator.

Question 12General operational requirements, definitions and documentation

An operator's operations manual is found to contain a procedure that conflicts with a requirement of Annex 6. What is the correct position?

  1. The conflict is acceptable if the manufacturer's manual also conflicts
  2. The manual prevails because it is approved by the operator's chief pilot
  3. The crew may choose whichever they consider safer on the day
  4. The State requirement prevails and the manual must be amended to comply Correct answer.

Explanation

The operations manual must not contain procedures that fall below the standards of the State of the Operator. Where a conflict exists, the regulation prevails and the manual must be corrected through the amendment process.

Question 13General operational requirements, definitions and documentation

What is the primary purpose of the journey log carried on board?

  1. To record the particulars of each flight, including departure and arrival points, times and any incidents Correct answer.
  2. To record the aircraft's fuel consumption for accounting purposes
  3. To document the crew's rostered days off for the current month
  4. To list all maintenance tasks due at the next base check

Explanation

The journey log records the details of each flight, such as points of departure and arrival, times and any relevant occurrences. It supports traceability of the aircraft's operation and is distinct from the technical log's defect and release record.

Question 14General operational requirements, definitions and documentation

Which statement about the carriage of the operations manual on board is correct for commercial air transport?

  1. The manual must be kept exclusively at the operator's head office
  2. A relevant part of the manual must be available on board for the crew to consult during flight Correct answer.
  3. The manual is required on board only for flights exceeding four hours
  4. Only the manufacturer's flight manual is required on board

Explanation

Annex 6 requires that the parts of the operations manual relevant to the crew's duties be accessible on board so that crews can refer to procedures and limitations during flight. Operators normally provide each aircraft with a controlled copy or an approved electronic version.

Question 15General operational requirements, definitions and documentation

An operator introduces an electronic flight bag to display performance calculations. Which requirement must be met before it can replace paper performance charts?

  1. The device must be purchased from the aircraft manufacturer
  2. The device must be switched off during all critical phases of flight
  3. The software and its use must be approved by the State of the Operator and have demonstrated equivalent accuracy and availability Correct answer.
  4. Only the pilot flying may use the device during take-off

Explanation

Electronic flight bags used for operational calculations require approval by the State of the Operator, with evidence of accuracy, redundancy and procedures for failure. Once approved, the operator defines the conditions of use in the operations manual.

Question 16General operational requirements, definitions and documentation

Which of the following is the correct description of a 'deferred defect' in the context of dispatch?

  1. A defect reported by cabin crew that has no effect on airworthiness
  2. A defect noted only for the information of the next crew without any action
  3. A defect that has been repaired but not yet certified by a licensed engineer
  4. A defect that is permitted to remain unrepaired for a defined period under the MEL with any associated conditions Correct answer.

Explanation

Deferring a defect means applying the MEL to allow dispatch with that item inoperative, subject to the stated rectification interval, operating conditions and any crew compensatory actions. It is a controlled decision, not simply ignoring the defect.

Question 17General operational requirements, definitions and documentation

A crew member is required to position as a passenger to another airport to operate a flight. How is this time treated?

  1. It is excluded from all records because no flight is operated
  2. It counts as flight time for the purpose of the flight time limitation
  3. It counts as duty time and must be recorded as such Correct answer.
  4. It is rest because the crew member is not operating

Explanation

Positioning time is duty, because the crew member is under the operator's control and is not free from duty. It is recorded as duty time and contributes to the cumulative duty and rest calculations even though no flight is operated.

Question 18General operational requirements, definitions and documentation

Which document establishes the operator's authority to conduct commercial air transport operations and states the types of operation permitted?

  1. The aerodrome operating licence issued by the aerodrome operator
  2. The Air Operator Certificate issued by the State of the Operator Correct answer.
  3. The maintenance organisation approval certificate
  4. The certificate of airworthiness issued for each aircraft

Explanation

The Air Operator Certificate authorises the operator to perform commercial air transport and specifies the types of aircraft and operations covered. Its associated operations specifications define the detailed authorisations and limitations.

Question 19General operational requirements, definitions and documentation

What does 'operations specifications' attached to an AOC typically contain?

  1. The company's fuel price contracts and route profitability analysis
  2. The personal licences and medical certificates of all flight crew
  3. The aircraft's weighing report and current mass and balance data
  4. Detailed authorisations, limitations and conditions such as approved aircraft types, areas of operation and special approvals Correct answer.

Explanation

Operations specifications set out the specific authorisations and limitations granted to the operator, including aircraft types, areas and routes, and special operational approvals such as low visibility or extended diversion time operations. They form part of the AOC framework.

Question 20General operational requirements, definitions and documentation

An operator changes its chief pilot. What is the usual regulatory consequence regarding the operations manual and AOC?

  1. No action is required because personnel changes are internal matters only
  2. The AOC is automatically suspended until a new chief pilot is approved
  3. The change must be notified to the State of the Operator, which may require an amendment to the manual and associated documentation Correct answer.
  4. The change must be approved by the aircraft manufacturer before it takes effect

Explanation

Key post-holders such as the chief pilot are named in the operator's documentation and are subject to acceptance by the State of the Operator. A change must be notified and the relevant parts of the manual and AOC documentation updated as required.

Question 21Operator certification, operational control and management systems

Under EU Regulation 965/2012 (Part-ORO), which document must an operator hold before it may commence commercial air transport operations with aeroplanes?

  1. A continuing airworthiness management contract with the manufacturer
  2. A maintenance organisation approval issued by EASA
  3. A design organisation approval issued by the state of registry
  4. An air operator certificate issued by the competent authority Correct answer.

Explanation

Part-ORO requires an operator to obtain an air operator certificate (AOC) from the competent authority of the member state before starting commercial air transport operations. The AOC defines the scope of authorised operations, the types of aircraft and the areas of operation. The other documents belong to different approval regimes and cannot substitute for the AOC.

Question 22Operator certification, operational control and management systems

In an operator's management system, which function is normally assigned to the accountable manager?

  1. Ensuring that all activities are financed and carried out to the required standard Correct answer.
  2. Certifying the aircraft as airworthy before each flight
  3. Performing the independent audit of the safety management system
  4. Conducting line checks on flight crew in the simulator

Explanation

The accountable manager has corporate authority for ensuring that all operations can be financed and carried out to the standard required by the competent authority. This responsibility is described in the operator's management system documentation and is a condition for issuing the AOC. Technical certification, training checks and audits are delegated to nominated persons.

Question 23Operator certification, operational control and management systems

Which statement best describes the role of the nominated person for flight operations in a commercial air transport operator?

  1. They issue the air operator certificate on behalf of the competent authority
  2. They are responsible for the management and supervision of flight operations on behalf of the operator Correct answer.
  3. They personally fly all route-proving flights required by the authority
  4. They hold ultimate financial responsibility for the whole company

Explanation

The nominated person for flight operations is responsible for the management and supervision of flight operations, including crew training and operational standards. They report to the accountable manager and must be acceptable to the competent authority. The other listed duties belong to different roles.

Question 24Operator certification, operational control and management systems

An operator wishes to add a new aircraft type to its fleet. Which action is required before the type may be used for commercial air transport?

  1. A notification to the manufacturer and an update of the MEL
  2. A safety risk assessment signed by the maintenance manager only
  3. An entry in the technical log approved by the pilot in command
  4. A variation of the AOC approved by the competent authority Correct answer.

Explanation

Adding a type to commercial operations changes the scope of the AOC and requires a variation approved by the competent authority. The operator must demonstrate that its organisation, training and procedures cover the new type. Internal documents such as the MEL or technical log do not authorise the operation.

Question 25Operator certification, operational control and management systems

What is the primary purpose of an operator's operations manual as required by Part-ORO?

  1. To serve as the maintenance programme for the aircraft fleet
  2. To replace the aircraft flight manual for normal operations
  3. To record the commercial contracts with tour operators
  4. To provide the crew with the information and procedures necessary to perform their duties Correct answer.

Explanation

The operations manual contains the instructions and information necessary for operations personnel to perform their duties, including normal, abnormal and emergency procedures. It is approved or accepted by the competent authority as applicable. It does not replace the AFM or the maintenance programme.

Question 26Operator certification, operational control and management systems

An operator's operations manual contains a procedure that conflicts with a limitation in the aircraft flight manual. Which document prevails?

  1. Whichever document was issued most recently
  2. The aircraft flight manual, because its limitations are certificated Correct answer.
  3. The operations manual, because it is approved by the authority
  4. The minimum equipment list, because it is more restrictive

Explanation

The AFM contains the certificated limitations of the aircraft and always takes precedence over company procedures. The operations manual must not contain procedures that conflict with the AFM. Any conflict must be resolved by amending the company documentation.

Question 27Operator certification, operational control and management systems

Under Part-ORO, which of the following is a required element of an operator's safety management system?

  1. A fixed number of line checks per pilot per year
  2. A guaranteed profit margin on charter flights
  3. A minimum fleet size of five aircraft
  4. A system for confidential reporting of occurrences Correct answer.

Explanation

A safety management system must include, among other elements, a confidential reporting system that encourages personnel to report occurrences and hazards. This supports hazard identification and safety risk management. Commercial targets, checking frequencies and fleet size are not SMS elements.

Question 28Operator certification, operational control and management systems

What distinguishes a compliance monitoring function from a safety assurance function in an operator's management system?

  1. Compliance monitoring verifies conformity with regulations and procedures, while safety assurance evaluates safety performance and risk controls Correct answer.
  2. Compliance monitoring applies only to maintenance, while safety assurance applies only to flight operations
  3. Compliance monitoring replaces the need for safety risk assessment in all cases
  4. Compliance monitoring is performed only by the authority, while safety assurance is performed by the operator

Explanation

Compliance monitoring checks that the organisation conforms to applicable requirements and its own procedures, typically through audits and inspections. Safety assurance focuses on whether safety risks are being controlled and whether the SMS is achieving its objectives. They are complementary but distinct functions.

Question 29Operator certification, operational control and management systems

A safety occurrence is reported internally. Which sequence best reflects the operator's safety risk management process?

  1. Identify the hazard, assess the risk, implement mitigation, and verify the effectiveness of the mitigation Correct answer.
  2. Notify the authority, suspend all operations, and wait for approval to resume
  3. Amend the MEL, retrain the crew, and cancel the report
  4. Record the occurrence, discipline the crew, and close the report

Explanation

Safety risk management follows hazard identification, risk assessment, mitigation and verification of effectiveness. This cycle is the core of the SMS and must be documented. Disciplinary action or blanket suspension is not the prescribed process.

Question 30Operator certification, operational control and management systems

Which statement correctly describes the operator's responsibility for operational control?

  1. Operational control means the authority to maintain the aircraft between flights
  2. Operational control means the commercial scheduling of aircraft and crew
  3. Operational control means the ability to override air traffic control instructions
  4. Operational control means the exercise of authority over the initiation, continuation, diversion or termination of a flight Correct answer.

Explanation

Operational control is the exercise of authority over the initiation, continuation, diversion or termination of a flight in the interest of safety and regularity. It is a core operator responsibility and must be defined in the operations manual. It does not mean overriding ATC or managing maintenance.

Question 31Operator certification, operational control and management systems

In a commercial air transport operation, who is ultimately responsible for the safe conduct of a flight?

  1. The pilot in command Correct answer.
  2. The accountable manager
  3. The nominated person for flight operations
  4. The flight dispatcher

Explanation

The pilot in command has final authority and responsibility for the safe conduct of the flight. Other personnel support the flight, but ultimate responsibility rests with the PIC. This principle is fundamental in operational procedures.

Question 32Operator certification, operational control and management systems

An operator uses a flight dispatch system for operational control. Which function is normally performed by the flight dispatcher?

  1. Certifying the aircraft's airworthiness after maintenance
  2. Authorising the pilot in command to deviate from ATC clearances
  3. Preparing the operational flight plan and monitoring the flight's progress Correct answer.
  4. Conducting the pre-flight walkaround inspection

Explanation

Flight dispatchers typically prepare operational flight plans, assess weather and fuel requirements, and monitor flights in coordination with the PIC. They do not certify maintenance or perform physical inspections. Authority over ATC clearances remains with the PIC and ATC.

Question 33Operator certification, operational control and management systems

Which of the following best describes the purpose of a minimum equipment list?

  1. To define the spare parts that must be carried on board
  2. To allow dispatch with specified equipment inoperative under defined conditions Correct answer.
  3. To list the minimum equipment required for an aircraft to be manufactured
  4. To record the defects that occurred during the previous flight

Explanation

The MEL, derived from the master minimum equipment list, permits operation with particular items of equipment inoperative, subject to specified conditions and limitations. It supports safe dispatch while maintaining an acceptable level of safety. It is not a manufacturing or spares document.

Question 34Operator certification, operational control and management systems

An operator's MEL permits dispatch with one generator inoperative, provided certain conditions are met. During pre-flight preparation the crew find the conditions cannot be satisfied. What is the correct course of action?

  1. Dispatch the aircraft and notify the authority after departure
  2. Do not dispatch the aircraft until the item is rectified or another approved procedure applies Correct answer.
  3. Dispatch the aircraft and record the deficiency in the technical log
  4. Dispatch the aircraft and reduce the passenger load to compensate

Explanation

The MEL conditions are part of the approval; if they cannot be met, the aircraft is not permitted to dispatch under that entry. The item must be rectified or another approved configuration found. Recording the deficiency or reducing the load does not satisfy the MEL conditions.

Question 35Operator certification, operational control and management systems

Which document normally contains the operator's procedures for the carriage of dangerous goods?

  1. The aircraft flight manual
  2. The minimum equipment list
  3. The maintenance programme
  4. The operations manual, including the relevant part dealing with dangerous goods Correct answer.

Explanation

Procedures for the carriage of dangerous goods, including acceptance, loading, notification and emergency response, are contained in the operations manual or an associated document referenced by it. The AFM, MEL and maintenance programme do not address these operational procedures.

Question 36Operator certification, operational control and management systems

An operator's fatigue risk management requires a pilot to report feeling unfit to fly due to fatigue. What is the appropriate operator response?

  1. Report the pilot to the authority for disciplinary action
  2. Deduct the lost flying hours from the pilot's salary
  3. Remove the pilot from duty in accordance with the operator's procedures and record the report Correct answer.
  4. Require the pilot to fly the duty and review the matter afterwards

Explanation

Fatigue reporting systems must allow crew to declare themselves unfit without fear of sanction, and the operator should remove the pilot from duty and record the occurrence. This supports the safety objective of the fatigue risk management system. Disciplinary or financial penalties would undermine reporting.

Question 37Operator certification, operational control and management systems

Which statement about a just culture within an operator's safety management system is most accurate?

  1. It applies only to maintenance personnel
  2. It prohibits the reporting of occurrences that involve human error
  3. It distinguishes between inadvertent errors and wilful violations when deciding on follow-up Correct answer.
  4. It requires that all errors be punished to deter repetition

Explanation

A just culture recognises that inadvertent errors should not be punished, while wilful violations or gross negligence may require action. This distinction encourages reporting and learning. It applies across the whole organisation and does not prohibit reporting.

Question 38Operator certification, operational control and management systems

Under Part-ORO, an operator must establish a security programme. Which element is most directly associated with that programme?

  1. Crew duty and rest time limitations
  2. Performance calculations for take-off and landing
  3. Procedures to prevent unlawful interference with aircraft and to screen access to the aircraft Correct answer.
  4. Fuel policy and reserve calculations

Explanation

The operator's security programme addresses measures to prevent acts of unlawful interference, including access control, screening and crew security training. Performance, fuel policy and duty limitations belong to other operational areas.

Question 39Operator certification, operational control and management systems

An operator's compliance monitoring manager reports directly to the accountable manager and is independent of the operational departments. Why is this independence important?

  1. It removes the need for an accountable manager
  2. It allows the compliance monitoring manager to command flights when required
  3. It allows the compliance monitoring manager to set commercial ticket prices
  4. It ensures audits can be conducted objectively without pressure from the areas being audited Correct answer.

Explanation

Independence protects the objectivity of audits and allows findings to be reported without pressure from the departments being reviewed. This is a recognised principle for compliance monitoring functions. It does not confer commercial or operational command authority.

Question 40Operator certification, operational control and management systems

An operator plans to operate a route where the destination aerodrome has no approved instrument approach and the weather forecast is marginal. Which management system element should drive the decision to proceed or cancel?

  1. The operator's documented safety risk assessment and operational control procedures Correct answer.
  2. The number of passengers already booked
  3. The commercial schedule agreed with the charterer
  4. The manufacturer's recommended cruise speed

Explanation

Decisions on marginal operations must be based on the operator's documented procedures, safety risk assessment and operational control arrangements. Commercial pressure cannot override safety considerations. Cruise speed and passenger numbers are irrelevant to the safety decision.

Question 41Crew composition, flight and duty time limitations and rest requirements

Under typical EASA flight time limitation rules, what is the maximum basic daily flight duty period for a crew member operating a single sector with a report time between 06:00 and 13:29 local time?

  1. 14 hours
  2. 12 hours
  3. 13 hours Correct answer.
  4. 11 hours

Explanation

The basic maximum flight duty period for a single-sector duty starting in the daytime band (reporting 06:00 to 13:29) is 13 hours. This figure is the baseline before any extension for additional sectors, in-flight rest or commander's discretion, and it is reduced for earlier or later report times.

Question 42Crew composition, flight and duty time limitations and rest requirements

A flight crew member reports for duty at 22:00 local time. Compared with a midday report, how is the maximum flight duty period normally affected?

  1. It is increased because night operations require extra crew
  2. It is reduced because of the circadian low and window of circadian low Correct answer.
  3. It is unchanged provided the crew is acclimatised
  4. It is determined only by the number of sectors flown

Explanation

Duty periods that encroach on the window of circadian low are subject to a reduction in the maximum flight duty period because alertness is degraded during that period. The reduction is applied to the table value according to the reporting time and the number of sectors.

Question 43Crew composition, flight and duty time limitations and rest requirements

What does the term 'acclimatised' mean for a flight crew member under flight time limitation rules?

  1. The crew member has completed a simulator check within the last 90 days
  2. The crew member's body clock has adapted to the local time at the point of departure Correct answer.
  3. The crew member holds a valid Class 1 medical certificate
  4. The crew member has flown at least 100 hours in the previous 12 months

Explanation

Acclimatisation is a physiological state in which the crew member's circadian rhythm has adapted to the local time zone of the departure point. It is normally presumed after a specified period of rest or duty at that reference time, and it determines which FDP table column applies.

Question 44Crew composition, flight and duty time limitations and rest requirements

Which of the following best describes 'standby duty' in the context of flight and duty time limitations?

  1. A period of flying as a supernumerary crew member
  2. A rest period at a hotel away from the home base
  3. A period during which the crew member must be contactable and available to report for duty Correct answer.
  4. Time spent in the simulator counting as flight time

Explanation

Standby is a defined duty period during which the crew member must be reachable and able to report for a flight at short notice. It may be at the airport or at another specified location, and it counts towards duty limits even when no flight is operated.

Question 45Crew composition, flight and duty time limitations and rest requirements

A commander is considering extending a flight duty period using commander's discretion. Which statement correctly reflects the usual constraint on that discretion?

  1. It converts the duty into rest for the purposes of the following rest period
  2. It may extend the duty period but the discretion is bounded by a specified maximum and must be reported Correct answer.
  3. It may be used without limit provided the commander records the reason
  4. It may only be used when the flight is a positioning leg

Explanation

Commander's discretion allows a limited extension of the flight duty period, but the amount is capped and the exercise must be recorded and reported to the operator. It cannot be used to override the absolute limits such as maximum flight time.

Question 46Crew composition, flight and duty time limitations and rest requirements

What is the purpose of a 'discretion' report submitted after a commander extends a duty period?

  1. To notify the operator so that fatigue risk can be monitored and mitigated Correct answer.
  2. To obtain an extension of the medical certificate
  3. To renew the crew member's type rating
  4. To request payment of an extra sector allowance

Explanation

Reporting the use of discretion gives the operator visibility of fatigue exposure so that trends can be analysed and mitigated. It is a safety-management feedback loop rather than an administrative or licensing formality.

Question 47Crew composition, flight and duty time limitations and rest requirements

Which item is normally excluded when calculating a crew member's flight duty period?

  1. A pure rest period at a suitable location during a split duty Correct answer.
  2. Time spent in the aircraft before departure
  3. Time spent on post-flight administration
  4. Time spent on pre-flight preparation at the operator's base

Explanation

A qualifying rest period during a split duty can be excluded from the flight duty period count, provided the facility and duration meet the prescribed conditions. Pre-flight, in-flight and post-flight duties all count towards the duty period.

Question 48Crew composition, flight and duty time limitations and rest requirements

An operator schedules a crew member for a duty that begins at 05:00 local time after a report at 04:30. Which factor most directly reduces the maximum flight duty period in this case?

  1. The length of the crew member's annual leave
  2. The aircraft's maximum take-off mass
  3. The early reporting time falling in the low-alertness window Correct answer.
  4. The number of passengers carried

Explanation

Reporting very early places the duty start inside the window of circadian low, so the applicable maximum flight duty period is reduced relative to the daytime baseline. The reduction reflects the elevated fatigue risk of operating at that hour.

Question 49Crew composition, flight and duty time limitations and rest requirements

A crew member operates two sectors with a report time of 07:00 local. The single-sector maximum is 13 hours. What is the most likely effect of the second sector?

  1. The maximum is reduced by a prescribed amount for the additional sector Correct answer.
  2. The maximum becomes unlimited if the commander agrees
  3. The maximum is increased because more flying is involved
  4. The maximum is unchanged because the report time is the only variable

Explanation

Each additional sector reduces the maximum flight duty period by a defined increment, because multiple take-offs and landings add workload and fatigue. The reduction is applied to the value obtained after the reporting-time adjustment.

Question 50Crew composition, flight and duty time limitations and rest requirements

A crew member is scheduled for a night flight departing at 23:30 and landing at 06:10 the next morning. Which consideration is most relevant to the legality of the planned duty?

  1. Whether the destination has a longer runway than the departure aerodrome
  2. Whether the duty encroaches on the window of circadian low and whether the resulting maximum is respected Correct answer.
  3. Whether the aircraft is equipped with autoland
  4. Whether the crew member has eaten before the flight

Explanation

A duty that spans the night-time hours encroaches on the window of circadian low, and the applicable maximum flight duty period must be checked against the planned duty length. If the planned duty exceeds the reduced maximum, the schedule is not compliant.
