Question 1Flight Planning and Fuel Management

Under standard flight planning rules, what does the term 'final reserve fuel' represent for a turbine-engine aeroplane?

  1. Fuel to fly for 45 minutes at normal cruising speed
  2. Fuel equal to 5 percent of the trip fuel
  3. Fuel to complete one missed approach and diversion to the alternate
  4. Fuel to fly for 30 minutes at holding speed at 1500 ft above the destination aerodrome Correct answer.

Explanation

Final reserve fuel is the minimum fuel that must remain when the aircraft lands, intended to protect against unforeseen delays. For turbine aeroplanes it is the fuel to hold for 30 minutes at 1500 ft above the aerodrome in ISA conditions. It is never planned for use in normal flight.

Question 2Flight Planning and Fuel Management

Which fuel component is added to cover the possibility that the flight is not conducted exactly as planned?

  1. Taxi fuel
  2. Alternate fuel
  3. Additional fuel
  4. Contingency fuel Correct answer.

Explanation

Contingency fuel is carried to compensate for unforeseen factors such as deviations from the planned route, winds, or consumption rates. It is normally a percentage of trip fuel or a time-based amount. Taxi, alternate, and additional fuel each cover different specific needs.

Question 3Flight Planning and Fuel Management

What is the purpose of the alternate fuel in a flight plan?

  1. To cover engine start and taxi at the departure aerodrome
  2. To fly from the destination to the destination alternate aerodrome Correct answer.
  3. To allow a diversion after the final reserve is used
  4. To hold over the destination for one hour

Explanation

Alternate fuel is the fuel required to fly from the destination aerodrome, or from the point where a missed approach is initiated, to the destination alternate. It includes a missed approach, climb, cruise, and approach. It does not include the final reserve.

Question 4Flight Planning and Fuel Management

In a flight plan, which speed is entered as the true airspeed for the cruise segment?

  1. The maximum operating speed of the aircraft
  2. The ground speed expected en route
  3. The planned cruise TAS for the segment Correct answer.
  4. The indicated airspeed at the top of climb

Explanation

The flight plan requires the true airspeed planned for each segment, because TAS is the air-referenced speed used with winds to derive ground speed. Indicated airspeed varies with altitude and is not used. Ground speed is computed by the planning system, not entered as TAS.

Question 5Flight Planning and Fuel Management

What does the abbreviation 'EOBT' mean in an ATS flight plan?

  1. Expected on-board time
  2. Estimated overhead beacon time
  3. Estimated off-block time Correct answer.
  4. Engine-out burn time

Explanation

EOBT is the estimated off-block time, the time the aircraft is expected to begin moving under its own power for departure. It is the reference time from which the flight plan is activated. It is not the take-off time.

Question 6Flight Planning and Fuel Management

Which of the following is the correct definition of trip fuel?

  1. Fuel needed to hold for 30 minutes
  2. Fuel needed from engine start to engine shutdown
  3. Fuel needed from take-off to landing at the destination Correct answer.
  4. Fuel needed to reach the alternate aerodrome

Explanation

Trip fuel is the fuel required from the point of take-off to touchdown at the destination, including climb, cruise, and descent. It excludes taxi fuel and reserves. It is the core consumption figure on which contingency fuel is often based.

Question 7Flight Planning and Fuel Management

What is the primary purpose of a destination alternate aerodrome in flight planning?

  1. To provide a landing option if a landing at the destination is not possible Correct answer.
  2. To provide weather information for the destination
  3. To serve as a refuelling stop on long routes
  4. To act as the departure aerodrome for the return leg

Explanation

A destination alternate is selected so that the aircraft has a viable landing option if the destination cannot be used due to weather or other reasons. It must meet specified weather and runway criteria at the expected time of arrival. It is not a technical stop or a weather source.

Question 8Flight Planning and Fuel Management

Which document normally provides the operator's approved fuel policy that a flight crew must follow?

  1. The airworthiness certificate
  2. The aircraft maintenance schedule
  3. The aerodrome directory
  4. The operations manual Correct answer.

Explanation

The operations manual contains the operator's approved procedures, including fuel policy and reserves. It is the reference document crews use for planning fuel. Maintenance schedules, aerodrome directories, and airworthiness certificates do not contain fuel policy.

Question 9Flight Planning and Fuel Management

An aircraft plans a 2-hour leg with trip fuel of 800 kg. If contingency fuel is 5 percent of trip fuel, how much contingency fuel is carried?

  1. 40 kg Correct answer.
  2. 16 kg
  3. 80 kg
  4. 400 kg

Explanation

Contingency fuel is calculated as a percentage of trip fuel: 5 percent of 800 kg equals 40 kg. This amount is added to the trip fuel to build the total fuel requirement. It covers unplanned deviations from the plan.

Question 10Flight Planning and Fuel Management

An aircraft has trip fuel 600 kg, taxi fuel 20 kg, contingency 30 kg, alternate 100 kg, and final reserve 150 kg. What is the minimum block fuel?

  1. 880 kg
  2. 750 kg
  3. 920 kg
  4. 900 kg Correct answer.

Explanation

Block fuel is the sum of taxi, trip, contingency, alternate, and final reserve fuel. Adding 20 + 600 + 30 + 100 + 150 gives 900 kg. Each component must be included to meet the planned requirement.

Question 11Flight Planning and Fuel Management

A flight departs with 2000 kg of fuel. Taxi burn is 30 kg, trip fuel is 1400 kg, and the final reserve is 150 kg. How much fuel remains above the final reserve on arrival, assuming the plan is flown exactly?

  1. 450 kg
  2. 420 kg Correct answer.
  3. 570 kg
  4. 270 kg

Explanation

Fuel at take-off is 2000 minus 30 taxi, equal to 1970 kg. After burning 1400 kg trip fuel, 570 kg remains. Subtracting the 150 kg final reserve leaves 420 kg above the reserve.

Question 12Flight Planning and Fuel Management

When must a destination alternate be nominated for an IFR flight?

  1. Only when the destination has a single runway
  2. Whenever the flight exceeds two hours
  3. When the destination weather at the expected time does not meet the required planning minima Correct answer.
  4. Never, if the aircraft carries extra fuel

Explanation

A destination alternate is required when the destination is not expected to meet the specified planning minima at the estimated time of arrival. If the destination is forecast to be suitable, an alternate may not be required under certain conditions. Flight duration alone does not determine the need.

Question 13Flight Planning and Fuel Management

What is the purpose of the 'additional fuel' component in a fuel plan?

  1. To allow extra holding at the destination only
  2. To cover cases where the fuel required by regulation is insufficient for the specific operation Correct answer.
  3. To cover taxi fuel at the departure aerodrome
  4. To replace the contingency fuel on short sectors

Explanation

Additional fuel is carried when the minimum regulatory fuel would not cover specific operational needs, such as a remote destination with no suitable alternate. It is added on top of the standard components. It does not replace contingency or taxi fuel.

Question 14Flight Planning and Fuel Management

In a flight plan, what does the 'route' field primarily describe?

  1. The alternate aerodrome approach procedure
  2. The designated air traffic services route or the direct track to be flown Correct answer.
  3. The magnetic heading after wind correction
  4. The aircraft's cruising altitude only

Explanation

The route field describes the ATS route designator or the sequence of points and tracks the flight will follow. It is not a heading, since headings change with wind. Altitude is entered separately in the level field.

Question 15Flight Planning and Fuel Management

An aircraft has a ground speed of 400 kt and must cover a leg of 800 NM. What is the planned leg time?

  1. 2 hours 00 minutes Correct answer.
  2. 1 hour 30 minutes
  3. 3 hours 00 minutes
  4. 2 hours 30 minutes

Explanation

Leg time equals distance divided by ground speed: 800 NM divided by 400 kt equals 2 hours. Ground speed already accounts for wind, so no further correction is needed.

Question 16Flight Planning and Fuel Management

Which fuel is normally excluded from the calculation of trip fuel?

  1. Descent fuel
  2. Climb fuel
  3. Cruise fuel
  4. Taxi fuel Correct answer.

Explanation

Trip fuel covers the airborne phases from take-off to landing, including climb, cruise, and descent. Taxi fuel is consumed on the ground and is accounted for separately. Including taxi fuel in trip fuel would distort contingency calculations.

Question 17Flight Planning and Fuel Management

What is the significance of the 'PIC' field in an ATS flight plan?

  1. It identifies the pilot in command by name Correct answer.
  2. It lists the emergency radio frequency
  3. It states the number of passengers on board
  4. It gives the aircraft's performance category

Explanation

The PIC field records the name of the pilot in command, which supports identification and search and rescue functions. It does not convey passenger numbers or performance data. Those items appear in other fields or documents.

Question 18Flight Planning and Fuel Management

A flight plan is filed with an EOBT of 0800. The aircraft becomes airborne at 0815. Which statement is correct regarding the flight plan?

  1. The EOBT must be changed to 0815 before start-up
  2. A new flight plan must be filed before departure
  3. The flight plan remains valid; the take-off time is recorded separately Correct answer.
  4. The flight plan is automatically cancelled at 0805

Explanation

The EOBT is the estimated off-block time, not the take-off time. A delay between off-block and airborne does not invalidate the flight plan. The actual take-off time is recorded by ATS separately.

Question 19Flight Planning and Fuel Management

What does the term 'reduced contingency fuel' allow an operator to do?

  1. Eliminate the final reserve on short flights
  2. Carry less contingency fuel when specific safety conditions and approval are met Correct answer.
  3. Replace alternate fuel with holding fuel
  4. Use trip fuel as the final reserve

Explanation

Reduced contingency fuel procedures permit a lower contingency amount when the operator meets specified conditions, such as approved fuel monitoring and suitable en-route alternates. It never allows removal of the final reserve. It does not affect alternate fuel requirements.

Question 20Flight Planning and Fuel Management

An aircraft must divert to its alternate 150 NM away. It descends and flies at a ground speed of 300 kt. What is the minimum alternate fuel time required for the diversion?

  1. 45 minutes
  2. 60 minutes
  3. 30 minutes Correct answer.
  4. 20 minutes

Explanation

Time equals distance divided by ground speed: 150 NM divided by 300 kt equals 0.5 hours, or 30 minutes. The alternate fuel must cover this diversion plus the approach. The final reserve remains separate and untouched.

Question 21Flight Planning and Fuel Management

An operator plans a flight where the destination forecast is marginal but an en-route alternate is available. Which planning consideration is most relevant to fuel?

  1. Whether the en-route alternate can be reached with the fuel available at the decision point Correct answer.
  2. Whether the alternate has a higher elevation than the destination
  3. Whether the destination has a longer runway than the alternate
  4. Whether the aircraft can carry more passengers

Explanation

When an en-route alternate is used, the fuel plan must show that the aircraft can reach it from the decision point with the required reserves intact. Runway length, passenger load, and elevation differences are secondary to the fuel reachability question. The decision point fuel must be sufficient for the diversion plus final reserve.

Question 22Flight Planning and Fuel Management

A flight has a planned trip fuel of 1200 kg. During flight, stronger headwinds increase consumption by 10 percent. If no contingency is used, how much extra fuel is burned compared with the plan?

  1. 120 kg Correct answer.
  2. 240 kg
  3. 100 kg
  4. 150 kg

Explanation

A 10 percent increase on 1200 kg is 120 kg of extra fuel. This additional burn must be covered by contingency fuel or other reserves. If contingency is insufficient, the crew must consider a diversion or reduced endurance.

Question 23Flight Planning and Fuel Management

What is the main reason for computing a 'point of no return' in fuel planning?

  1. To determine the point where the aircraft must contact ATC
  2. To identify the point beyond which the aircraft can no longer return to the departure aerodrome with the fuel available Correct answer.
  3. To mark the start of the descent profile
  4. To identify where the alternate fuel becomes available

Explanation

The point of no return is the position beyond which the aircraft cannot return to the departure aerodrome with the fuel remaining. It is a fuel-based decision point used for planning and in-flight monitoring. It is not an ATC reporting point or a descent marker.

Question 24Flight Planning and Fuel Management

An aircraft plans to arrive with exactly the final reserve fuel. Which statement best describes the risk?

  1. There is no margin for any unforeseen delay or deviation Correct answer.
  2. The flight is fully compliant and safe
  3. The final reserve can be reduced in flight
  4. The alternate fuel can be used instead

Explanation

Arriving with only the final reserve means no contingency remains for unexpected holding, weather, or routing changes. Any deviation would erode the reserve, which must remain intact at landing. The final reserve is a minimum, not a target.

Question 25Flight Planning and Fuel Management

Which of the following best describes how wind affects the fuel plan for a given route?

  1. A headwind increases trip fuel and a tailwind reduces it Correct answer.
  2. Wind only affects the alternate fuel
  3. Wind has no effect on trip fuel
  4. A tailwind always increases trip fuel

Explanation

Wind changes ground speed, which changes the time spent en route and therefore the fuel burned. A headwind lowers ground speed and increases trip fuel, while a tailwind has the opposite effect. Wind affects all segments, not just the alternate.

Question 26Flight Planning and Fuel Management

In fuel planning, what does the term 'final reserve fuel' represent?

  1. The fuel required to fly for a specified time at holding speed at the destination alternate
  2. The fuel needed to taxi from the apron to the runway holding point
  3. The total fuel loaded minus the trip fuel and contingency fuel
  4. The fuel that must remain when the aircraft lands, calculated at holding speed at a stated height above the destination Correct answer.

Explanation

Final reserve fuel is the minimum fuel that must be remaining on arrival, computed as the fuel needed to hold for a defined period at holding speed at a specified height above the aerodrome. It is a safety buffer against unforeseen delays and is not intended for normal flight to the alternate.

Question 27Flight Planning and Fuel Management

An aircraft has a maximum take-off mass of 6500 kg and a basic operating mass of 4200 kg. Payload is 800 kg. If the planned trip fuel is 700 kg and taxi fuel is 20 kg, what is the maximum additional fuel that can be loaded while remaining within the take-off mass limit?

  1. 760 kg
  2. 1500 kg
  3. 780 kg Correct answer.
  4. 800 kg

Explanation

The take-off mass comprises basic operating mass, payload, taxi fuel and all fuel on board at take-off. Available fuel is 6500 minus 4200 minus 800, giving 1500 kg total fuel; subtracting the 700 kg trip fuel and 20 kg taxi fuel leaves 780 kg for other fuel components.

Question 28Flight Planning and Fuel Management

Which statement correctly describes the purpose of the 'alternate fuel' component?

  1. It covers fuel from the missed approach point at the destination to landing at the alternate Correct answer.
  2. It covers fuel for engine start, taxi and run-up at the departure aerodrome
  3. It covers fuel for a diversion from any point along the route to the departure aerodrome
  4. It covers fuel burned while holding at the destination before diversion

Explanation

Alternate fuel is the fuel required to fly from the destination, normally from the missed approach point, to the nominated alternate and then descend and land. It does not include any holding at the destination, which is covered by contingency fuel.

Question 29Flight Planning and Fuel Management

A pilot plans to depart with fuel equal to trip fuel plus alternate fuel plus final reserve, omitting contingency fuel. Which statement best describes the consequence of this plan?

  1. The plan is acceptable because the final reserve already covers all contingencies
  2. The plan is acceptable provided the destination weather is forecast to be fine
  3. The plan lacks the required buffer for unforeseen factors such as wind, routing or consumption changes Correct answer.
  4. The flight is fully compliant because contingency fuel is optional for all flights

Explanation

Contingency fuel exists specifically to absorb unforeseen increases in consumption or route changes and is a required element of the fuel plan. Omitting it leaves the flight without margin, and the final reserve must not be used as routine contingency.

Question 30Flight Planning and Fuel Management

An aircraft's fuel plan shows trip fuel 900 kg, contingency 45 kg, alternate 120 kg and final reserve 140 kg, with taxi fuel 15 kg. During flight, 60 kg more fuel than planned is burned before reaching the destination. Which statement is correct on arrival overhead the destination, assuming no other changes?

  1. The aircraft has lost only the contingency fuel and the alternate fuel remains untouched
  2. The aircraft can still divert to the alternate and land with the final reserve intact Correct answer.
  3. The aircraft can hold at the destination for the full planned holding period and still divert
  4. The aircraft must land immediately because the final reserve has been breached

Explanation

The total fuel above the final reserve is the contingency plus alternate fuel, which here is 165 kg. An extra burn of 60 kg consumes part of that margin but leaves 105 kg, which still covers the 120 kg alternate requirement only if the shortfall is absorbed by the contingency; the remaining margin above final reserve is 105 kg, so the alternate diversion remains feasible within the protected reserve.

Question 31Aerodrome Operations and Ground Procedures

On an aerodrome with a designated taxiway holding position marked by a single solid line and a single dashed line, from which side must an aircraft approach when taxiing toward the runway?

  1. From the side indicated by the yellow taxiway centreline
  2. From the side with the solid lines
  3. From either side, provided ATC clearance is held
  4. From the side with the dashed lines Correct answer.

Explanation

At a runway holding position the dashed line faces the taxiway and the solid lines face the runway. An aircraft approaching the runway crosses the dashed line first, so it must approach from the dashed side. Approaching from the solid side would mean the aircraft is leaving the runway environment.

Question 32Aerodrome Operations and Ground Procedures

What is the standard meaning of a flashing red light signal directed at an aircraft on the ground?

  1. Taxi clear of the runway in use Correct answer.
  2. Cleared to taxi
  3. Return to starting point on the aerodrome
  4. Stop

Explanation

A flashing red signal to an aircraft on the ground means taxi clear of the runway in use. A steady red means stop, and a flashing white means return to starting point. Confusing these signals can lead to runway incursion.

Question 33Aerodrome Operations and Ground Procedures

An aircraft is instructed to hold short of runway 04 at a marked holding position. What does this instruction require the pilot to do?

  1. Stop on the runway centreline and wait for take-off clearance
  2. Hold at the apron entry until the tower issues a taxi clearance
  3. Stop before the holding position marking and not cross it without further clearance Correct answer.
  4. Reduce speed and continue taxiing while monitoring the tower frequency

Explanation

Holding short requires the aircraft to stop before the holding position marking and remain clear of the runway and its protected area. The aircraft must not cross the marking until ATC issues an explicit crossing or line-up clearance. This protects the runway strip from incursions.

Question 34Aerodrome Operations and Ground Procedures

Which condition most accurately describes a runway incursion?

  1. Any unauthorised presence on a runway or protected area of a runway Correct answer.
  2. Any vehicle crossing a taxiway without a radio
  3. Any aircraft entering the apron without a marshaller present
  4. Any aircraft that lands long and overruns the touchdown zone

Explanation

A runway incursion is any unauthorised presence on a runway or a protected area of a runway, whether by an aircraft, vehicle or person. It is defined by the unauthorised presence, not by the outcome. Incursions are classified by severity according to the risk of collision.

Question 35Aerodrome Operations and Ground Procedures

What does a runway designation marking of 27 indicate about the runway?

  1. It is the twenty-seventh runway at the aerodrome
  2. Its true direction is exactly 270 degrees
  3. It is 2700 metres long
  4. Its magnetic direction is approximately 270 degrees Correct answer.

Explanation

Runway designation numbers indicate the magnetic direction of the runway rounded to the nearest ten degrees, with the final zero omitted. A marking of 27 therefore corresponds to approximately 270 degrees magnetic. True direction is not used for runway numbering.

Question 36Aerodrome Operations and Ground Procedures

During taxi, a pilot sees steady green arrows from the tower. What is the correct interpretation?

  1. Stop immediately and await further signals
  2. Cleared to taxi in the direction of the arrows Correct answer.
  3. Cleared for take-off
  4. Taxi clear of the runway in use

Explanation

Green arrows are used to direct an aircraft to taxi in the direction indicated by the arrows. They are typically used where voice communication is unavailable or to reinforce instructions. They do not authorise take-off.

Question 37Aerodrome Operations and Ground Procedures

An aircraft is taxiing at night on a controlled aerodrome and the pilot becomes uncertain of the taxi route. What is the safest action?

  1. Stop the aircraft and request progressive taxi instructions from ATC Correct answer.
  2. Continue slowly along the centreline until familiar features are recognised
  3. Turn onto the nearest taxiway that appears to lead toward the runway
  4. Follow the aircraft ahead regardless of its destination

Explanation

When uncertain of position or route, the pilot should stop and request progressive taxi instructions. Continuing while unsure risks entering a runway or an unsuitable surface. Following another aircraft may lead to an incorrect location.

Question 38Aerodrome Operations and Ground Procedures

Which marking identifies a taxiway that is not usable for aircraft movement?

  1. A red and white chevron pattern
  2. A yellow cross on the taxiway Correct answer.
  3. A yellow taxiway centreline
  4. A white runway centreline

Explanation

A yellow cross marks a closed taxiway or portion of a taxiway that is unfit for aircraft movement. It is distinct from runway closure markings, which use white crosses. Pilots must not taxi over a closed taxiway marking.

Question 39Aerodrome Operations and Ground Procedures

What is the purpose of a runway holding position marking at an intersection with a taxiway?

  1. To show the boundary of the apron
  2. To mark the start of the take-off run
  3. To indicate where an aircraft must stop before entering the runway environment Correct answer.
  4. To indicate the touchdown zone

Explanation

Runway holding position markings define where an aircraft must stop when instructed to hold short of a runway. They protect the runway strip and prevent incursions. The marking does not authorise entry to the runway.

Question 40Aerodrome Operations and Ground Procedures

An aircraft is cleared to line up and wait on runway 15. What does this clearance authorise?

  1. Enter the runway, take off, and remain in the pattern
  2. Cross the runway and continue taxiing to the apron
  3. Enter the runway and hold in position, but not begin take-off Correct answer.
  4. Enter the runway and begin the take-off roll immediately

Explanation

Line up and wait authorises the aircraft to enter the runway and position itself for departure, but not to begin the take-off roll. Take-off clearance must be issued separately. Beginning the roll without it is a serious infringement.

Question 41Aerodrome Operations and Ground Procedures

Which factor most directly determines the minimum separation applied between two departing aircraft on the same runway?

  1. The colour of the runway markings
  2. The number of taxiways at the aerodrome
  3. The wake turbulence category of the preceding aircraft Correct answer.
  4. The type of approach lighting installed

Explanation

Wake turbulence separation minima are based primarily on the wake turbulence categories of the preceding and following aircraft. Heavier preceding aircraft generate stronger wake vortices requiring greater spacing. Other factors such as runway condition may also apply but the category is fundamental.

Question 42Aerodrome Operations and Ground Procedures

An aircraft is instructed to hold at a runway holding position while another aircraft lands. When may it cross the holding position?

  1. When the landing aircraft has vacated the runway without ATC instruction
  2. Only after receiving an explicit clearance from ATC Correct answer.
  3. When the pilot judges that sufficient spacing exists
  4. As soon as the landing aircraft touches down

Explanation

An aircraft must not cross a runway holding position without an explicit clearance from ATC. The pilot may not self-authorise crossing even if the runway appears clear. This rule underpins runway incursion prevention.

Question 43Aerodrome Operations and Ground Procedures

What does a white 'T' marking on the movement area of an aerodrome indicate?

  1. A taxiway intersection
  2. A touchdown zone marker
  3. A designated helicopter landing or take-off area Correct answer.
  4. A runway holding position

Explanation

A white T marking designates a helicopter landing or take-off area on an aerodrome. It is distinct from fixed-wing runway and taxiway markings. Pilots of fixed-wing aircraft should not confuse it with a threshold or holding position.

Question 44Aerodrome Operations and Ground Procedures

An aircraft has just landed and is instructed to vacate via a rapid exit taxiway. What should the pilot expect regarding the taxi speed?

  1. Stop on the runway before turning off
  2. Accelerate to clear the runway quickly
  3. Maintain landing speed until clear of the runway
  4. Reduce speed to a safe taxi speed after vacating the runway Correct answer.

Explanation

After vacating the runway via a rapid exit taxiway, the pilot should reduce to a safe taxi speed appropriate to the taxiway. Runway vacating speed may be higher, but taxiway speed limits and conditions apply once clear. Stopping on the runway is unsafe unless instructed.

Question 45Aerodrome Operations and Ground Procedures

Which of the following best describes the purpose of a runway strip?

  1. To provide a clearway for take-off
  2. To protect aircraft flying over it and reduce the risk of damage in the event of a runway excursion Correct answer.
  3. To provide a prepared surface for aircraft to park
  4. To mark the boundary of the aerodrome

Explanation

The runway strip is a defined area including the runway and stopway, intended to protect aircraft flying over it and to reduce the risk of damage if an aircraft leaves the runway. It must be clear of obstacles that could endanger aircraft. It is distinct from the clearway.

Question 46Aerodrome Operations and Ground Procedures

An aircraft is taxiing on a taxiway marked with a yellow centreline and blue edge lights. What do the blue lights indicate?

  1. The holding position
  2. The apron boundary
  3. The taxiway edge Correct answer.
  4. The runway edge

Explanation

Blue lights are used to mark the edges of taxiways at night or in low visibility. They help pilots keep the aircraft on the taxiway surface. Runway edge lights are white, and holding positions are marked by other means.

Question 47Aerodrome Operations and Ground Procedures

What is the correct action if a pilot receives a taxi clearance that would require crossing a runway, but the clearance does not explicitly mention the runway crossing?

  1. Continue taxiing and report the crossing after it is completed
  2. Cross the runway only if no other aircraft are visible
  3. Proceed across the runway as part of the taxi route
  4. Stop before the runway and request clarification from ATC Correct answer.

Explanation

A clearance that does not explicitly authorise a runway crossing should be treated as not permitting the crossing. The pilot should stop before the runway and request clarification. This practice prevents misunderstandings that lead to incursions.

Question 48Aerodrome Operations and Ground Procedures

Which of the following is a standard marshalling signal indicating that an aircraft should stop?

  1. Arms repeatedly crossed above the head Correct answer.
  2. Arms extended horizontally with palms forward
  3. Both arms raised and waved downward
  4. Right arm raised vertically with a clenched fist

Explanation

The stop signal given by a marshaller consists of arms repeatedly crossed above the head. This signal is unambiguous and should be obeyed immediately. Other signals convey different instructions such as proceed or slow down.

Question 49Aerodrome Operations and Ground Procedures

An aircraft is parked on an apron and the pilot wishes to start engines. What is the most appropriate initial action?

  1. Start engines immediately to save time
  2. Confirm that the apron area is clear and obtain any required clearance from ground control Correct answer.
  3. Signal the marshaller to move the aircraft
  4. Request take-off clearance from the tower

Explanation

Before starting engines on an apron, the pilot should ensure the area is clear and obtain any required clearance from ground or apron control. Engine start can create jet blast and suction hazards. Take-off clearance is irrelevant at this stage.

Question 50Aerodrome Operations and Ground Procedures

What is the significance of a red and white chevron marking on the movement area?

  1. It indicates a taxiway centreline
  2. It indicates a runway threshold
  3. It indicates an obstacle or a non-load-bearing area Correct answer.
  4. It indicates a runway holding position

Explanation

Red and white chevrons are used to mark obstacles or areas that are not load-bearing and should not be entered. They warn pilots to keep clear. They are distinct from runway and taxiway markings.
