Question 1Air safety

What is the maximum height above the surface at which a drone may be flown in the Open category in the UK?

  1. 60 m
  2. 400 m
  3. 150 m
  4. 120 m Correct answer.

Explanation

Open category flights are limited to 120 m, which is about 400 ft, above the surface. The limit is measured from the ground directly beneath the aircraft rather than from the take-off point. Flying higher needs a specific authorisation.

Question 2Air safety

What does maintaining visual line of sight (VLOS) mean?

  1. Seeing the aircraft itself, with spectacles if needed Correct answer.
  2. Relying on the live camera image on the controller
  3. Using binoculars to keep the aircraft in view
  4. Having a second person follow it through a telescope

Explanation

VLOS means the remote pilot can see the aircraft itself with the unaided eye, apart from corrective lenses, so that its position and orientation can be judged. Camera images and magnifying devices do not satisfy the requirement.

Question 3Air safety

Which source would you consult to confirm whether the airspace over a new site is controlled?

  1. The current aeronautical chart for the area Correct answer.
  2. The battery storage record
  3. The local weather forecast
  4. The aircraft's operating manual

Explanation

Airspace classification, prohibited areas and restricted areas are published on aeronautical charts. Checking the chart is a basic part of flight planning before flying at an unfamiliar site.

Question 4Air safety

At what state of charge should a lithium polymer flight battery normally be stored?

  1. Between 80% and 100%
  2. Around 30% to 50% Correct answer.
  3. Fully charged to 100%
  4. Completely discharged

Explanation

Lithium polymer packs are stored at roughly half charge, typically 30 to 50 per cent, or about 3.8 V per cell. Storing at full charge or leaving a pack flat accelerates ageing and increases the risk of damage.

Question 5Air safety

Who is ultimately responsible for avoiding a collision between the drone and a manned aircraft?

  1. The air traffic controller on duty
  2. The manufacturer of the drone
  3. The remote pilot Correct answer.
  4. The pilot of the manned aircraft

Explanation

The remote pilot must keep the aircraft clear of manned traffic and give way to it at all times. No other party can discharge that duty on the pilot's behalf.

Question 6Air safety

What must a remote pilot obtain before flying inside the flight restriction zone of a protected aerodrome?

  1. A CAA-issued NOTAM authorising the flight
  2. Nothing, as long as the flight stays below 120 m
  3. Only a valid Operator ID
  4. Permission from the aerodrome's ATC or operator Correct answer.

Explanation

Flight restriction zones protect manned operations around protected aerodromes. Entry requires prior permission from the aerodrome air traffic control unit or, where none exists, the aerodrome operator.

Question 7Air safety

A flight battery feels slightly swollen after a flight. What is the correct action?

  1. Remove it from service and dispose of it safely Correct answer.
  2. Continue using it but shorten each flight
  3. Charge it at a reduced current to restore the cells
  4. Store it fully charged so the cells can recover

Explanation

Swelling shows internal damage and gas generation, which can lead to fire. The pack should be taken out of service, kept away from combustible material and disposed of at a suitable recycling point.

Question 8Air safety

A remote pilot with an A2 CofC is flying a Class C2 drone in the A2 subcategory. What minimum horizontal distance must be kept from uninvolved people?

  1. 50 m
  2. 15 m
  3. 5 m
  4. 30 m Correct answer.

Explanation

In the A2 subcategory the aircraft must stay at least 30 m horizontally from uninvolved people. That distance may fall to 5 m only when low-speed mode is selected.

Question 9Air safety

The command and control link is lost while the drone is airborne. What is the correct expectation?

  1. It continues on its last heading until the battery runs out
  2. It climbs to 120 m and waits for the link to return
  3. It always lands immediately at its present position
  4. It follows the failsafe set before take-off Correct answer.

Explanation

Link-loss behaviour is chosen by the remote pilot before flight, typically hold, land or return to home. Because the outcome is pre-programmed, the setting must be checked against the site before take-off.

Question 10Air safety

Why should compass calibration be avoided on a steel-framed loading bay?

  1. The aircraft's motors may overheat in an enclosed space
  2. Calibration cannot be completed unless the aircraft is on grass
  3. Magnetic interference can cause a false calibration Correct answer.
  4. The GPS signal is blocked by the bay's concrete floor

Explanation

Large steel structures distort the local magnetic field, so the calibration records an incorrect reference. The aircraft may then show heading errors or fly poorly until it is recalibrated away from metal.

Question 11Air safety

Why does a lithium polymer battery deliver less usable energy in cold weather?

  1. The cells lose electrolyte through their vents
  2. The flight controller regulates the voltage down
  3. The chemical reactions in the cells slow down Correct answer.
  4. Cold air increases resistance in the motor windings

Explanation

Low temperatures slow the electrochemical reactions, so internal resistance rises and less capacity is available. The pack should be kept warm before flight and flight times reduced in the cold.

Question 12Air safety

A planned flight would take place inside Class D controlled airspace. What is required?

  1. A clearance from the controlling ATC unit Correct answer.
  2. Nothing extra, because Class D is uncontrolled airspace
  3. A Flyer ID only
  4. A NOTAM issued for the flight by the CAA

Explanation

Class D is controlled airspace in which air traffic control provides a service to all flights. A drone may only enter with a clearance, which must be obtained in advance and then complied with.

Question 13Air safety

What is the purpose of a NOTAM?

  1. To show permanent airspace boundaries and frequencies
  2. To flag temporary hazards affecting flight Correct answer.
  3. To forecast weather for the next 24 hours
  4. To record the pilot's flight hours and currency

Explanation

A notice to airmen is issued when information important to flight is needed before it can be published by other means, such as a temporary restriction or a crane operation. NOTAMs must be checked during pre-flight planning.

Question 14Air safety

Which behaviour is described as 'get-home-itis'?

  1. Feeling unwell because of vibration and noise
  2. Pressing on to reach the planned end point Correct answer.
  3. Becoming overconfident after many uneventful flights
  4. Failing to notice a warning on the controller

Explanation

Get-home-itis is the pressure a pilot feels to finish the task or return to base, which can lead to worsening conditions being ignored. Recognising the pressure allows a deliberate decision to divert, land or abandon the flight.

Question 15Air safety

The surface wind is 8 kt but the wind at 120 m is forecast at 22 kt. What is the main operational consequence?

  1. The drone will climb more slowly than normal
  2. More battery is used into wind and headway may be lost Correct answer.
  3. The GPS position will become inaccurate at height
  4. The motors will run cooler because of the increased airflow

Explanation

Wind speed increases with height, so the aircraft meets a stronger headwind aloft than on the ground. This reduces ground speed and endurance in one direction and may make it impossible to return against the wind.

Question 16Air safety

In the A3 subcategory, what minimum horizontal distance must be kept from residential, commercial, industrial and recreational areas?

  1. 50 m
  2. 150 m Correct answer.
  3. 30 m
  4. 120 m

Explanation

A3 flights must take place well away from people and built-up surroundings. The rule sets a minimum of 150 m from residential, commercial, industrial and recreational areas.

Question 17Air safety

Which statement is correct for the A1 subcategory?

  1. You may never fly over any person under any circumstances
  2. You may fly over assemblies of people if you stay above 50 m
  3. You may fly over crowds if you hold an A2 CofC
  4. You may overfly individuals but never a crowd Correct answer.

Explanation

A1 permits flight over uninvolved individuals, but overflight of assemblies of people such as crowds, beaches or festivals is prohibited without a specific authorisation. The A2 CofC does not change that.

Question 18Air safety

Two aircraft are converging at the same level. Which one must give way?

  1. The one flying at the lower altitude
  2. The slower aircraft
  3. The aircraft that has the other on its right Correct answer.
  4. The aircraft that has the other on its left

Explanation

The standard rule is that the aircraft with the other on its right gives way, which makes the outcome predictable. For a drone the overriding rule remains that it must always give way to manned aircraft.

Question 19Air safety

What is the main purpose of carrying out a site survey before the first flight at a new location?

  1. To confirm the drone is registered for commercial use
  2. To identify hazards and safe landing areas Correct answer.
  3. To record battery voltages in the maintenance log
  4. To measure the exact wind speed at 120 m

Explanation

A survey identifies wires, masts, trees, people and suitable launch and emergency landing areas before flight. That information feeds the risk assessment and the choice of flight boundaries.

Question 20Air safety

A helicopter passes close to your drone and you judge that safety was compromised. What should you do?

  1. Nothing, because manned aircraft always have right of way
  2. Submit an airprox report to the appropriate authority Correct answer.
  3. Wait for the helicopter operator to make a report
  4. Record the event only in your personal logbook

Explanation

An airprox is a situation in which the distance and geometry between aircraft put safety at risk. It should be reported promptly so that the occurrence can be investigated and lessons shared.

Question 21Air safety

A Class C2 aircraft is flown in the A2 subcategory with low-speed mode selected. What minimum horizontal distance applies to uninvolved people?

  1. 15 m
  2. 50 m
  3. 5 m Correct answer.
  4. 30 m

Explanation

Low-speed mode reduces the aircraft's maximum speed and allows the separation from uninvolved people to fall from 30 m to 5 m. The aircraft must still never be flown over them.

Question 22Air safety

GPS reception is lost while the aircraft is holding a GPS-dependent position. What is the most likely consequence?

  1. It will lose all control of the camera gimbal
  2. It will fall out of the sky immediately
  3. It may hold altitude but drift with the wind Correct answer.
  4. It will descend at twice its normal rate

Explanation

Without position fixing the aircraft cannot hold a ground position and tends to drift with the wind, and automatic functions such as return to home may become unavailable. The pilot must be ready to take manual control immediately.

Question 23Air safety

The return-to-home altitude is set at 40 m, but the return path crosses 25 m trees on ground that rises 30 m towards home. What is the safest action?

  1. Disable return to home and rely on manual flight
  2. Raise it to clear the rising ground and the trees Correct answer.
  3. Leave the setting, because 40 m clears 25 m trees
  4. Reduce the setting to 30 m to keep well below the trees

Explanation

Return-to-home height is referenced to the home point, so rising terrain can place obstacles above the aircraft's return altitude. The setting must be checked against the highest terrain and obstacle on the whole return path.

Question 24Air safety

You intend to fly near a hospital with a marked helipad, in Class G airspace. What is the most important consideration?

  1. Class G airspace excludes air ambulance operations
  2. Helicopters only operate above 500 ft, so there is no conflict
  3. Helicopters may operate low, so stay well clear Correct answer.
  4. The airspace around a hospital helipad is closed to drones

Explanation

Air ambulance and other helicopters may operate well below 120 m and outside controlled airspace, often on tracks that are hard to predict. The remote pilot must keep clear of approach and departure paths and stay alert for low-level traffic.

Question 25Air safety

You are flying towards ground that rises ahead of you. What does the 120 m height limit apply to?

  1. The highest ground within 500 m of the aircraft
  2. The ground directly beneath the aircraft Correct answer.
  3. Mean sea level at the aircraft's position
  4. The point from which the aircraft was launched

Explanation

The limit is measured from the surface immediately below the aircraft, so the permitted height above sea level changes as the aircraft moves over rising or falling terrain. It is not referenced to the launch point.

Question 26Air safety

A remote pilot drinks a small amount of alcohol with a meal a few hours before flying and feels completely normal. Why does this still matter for flight safety?

  1. Alcohol improves concentration by reducing pre-flight anxiety
  2. Even small amounts can degrade judgement and reaction time Correct answer.
  3. Alcohol only impairs performance once a legal driving limit is exceeded
  4. Alcohol affects only night vision, so daylight flights are unaffected

Explanation

Alcohol is a depressant that slows reaction time and reduces the quality of decision-making before any obvious feeling of intoxication appears. Remote pilots are responsible for the safety of people and property below, so any substance that degrades judgement is incompatible with flying. Feeling normal is not evidence that performance is unimpaired.

Question 27Air safety

During the pre-flight inspection you find small nicks and fine cracks along the edge of one propeller blade. Why does this matter?

  1. It makes the aircraft drift slowly when holding a GPS position
  2. It weakens the command and control radio link
  3. A damaged blade can fail or vibrate, causing loss of control Correct answer.
  4. It only affects appearance and can be left until the next service

Explanation

Propeller blades are highly stressed and spin at high speed, so cracks and nicks concentrate stress and can grow quickly in flight. A blade that fails or sheds material creates severe vibration and asymmetric thrust that the flight controller may not be able to counter. The aircraft should not be flown until the blade is replaced.

Question 28Air safety

You are on final descent to land when a member of the public walks into the area directly beneath your aircraft. What is the safest course of action?

  1. Shout a warning and complete the landing as planned
  2. Descend to just above head height and hover over them
  3. Keep the aircraft clear of the area and wait until it is empty Correct answer.
  4. Land quickly before the person moves any further

Explanation

The remote pilot must keep people not involved in the flight at a safe distance at all times, including during take-off and landing. Continuing a descent over an unaware person removes any margin for error if control is lost. The correct response is to hold the aircraft away from the occupied area until it is clear.

Question 29Air safety

A strong wind is blowing across a large hangar beside your flying site. What should you expect when flying on the downwind side of the building?

  1. Smoother air, because the building shelters the area from the wind
  2. No change, because buildings only affect wind at ground level
  3. Turbulence and downdraughts that can disturb the aircraft Correct answer.
  4. Steady rising air that helps the aircraft hold its height

Explanation

Wind flowing over and around a large obstruction breaks up into eddies and descending air on its lee side. This disturbed air can cause sudden height loss or uncommanded movement that may exceed the aircraft's ability to hold position. Pilots should anticipate this and keep well clear or avoid flying there in strong winds.

Question 30Air safety

You are flying at about 100 m when you see a manned light aircraft at a similar height roughly one kilometre away, and its flight path is not yet clear. What is the most appropriate immediate action?

  1. Hold a hover at your present height until the aircraft has passed
  2. Continue the flight and rely on the drone's obstacle sensors
  3. Descend and turn away while keeping the aircraft in sight Correct answer.
  4. Climb to pass above the aircraft and maintain your track

Explanation

The remote pilot must give way to manned aircraft and must be able to see and avoid conflicting traffic. Losing height and turning away increases separation and puts the drone below the manned aircraft's likely flight path. A hovering drone stays in the same block of airspace and remains a hazard.

Question 31Airspace restrictions and UAS geographical zones

What is the lateral extent of the flight restriction zone (FRZ) around a protected aerodrome in the UK?

  1. 1 km from the aerodrome boundary fence
  2. 500 m from the end of each runway
  3. 2 nautical miles from the runway threshold
  4. 5 km from the aerodrome reference point Correct answer.

Explanation

The flight restriction zone around a protected aerodrome is based on a 5 km radius measured from the aerodrome reference point, with additional protection beyond the runway ends. Flying a UAS inside this zone requires permission from the aerodrome's air traffic control unit or operator. The zone is not defined by the perimeter fence, the runway thresholds or the runway ends alone.

Question 32Airspace restrictions and UAS geographical zones

Which source should a remote pilot consult for current airspace restrictions before planning a flight in the UK?

  1. The local council website
  2. The aircraft's quick start guide
  3. The NATS Drone Safety Map Correct answer.
  4. The manufacturer's geofence list

Explanation

Current restrictions such as flight restriction zones, prohibited areas and notified temporary restrictions are shown on the NATS Drone Safety Map, which consolidates official airspace information. The remote pilot remains responsible for confirming that the planned flight does not enter restricted airspace. Manufacturer data and general websites do not constitute official airspace information.

Question 33Airspace restrictions and UAS geographical zones

When flying a C2-class UAS in the A2 subcategory, what is the minimum horizontal distance that must normally be kept from uninvolved people?

  1. 15 m
  2. 50 m
  3. 5 m
  4. 30 m Correct answer.

Explanation

The A2 subcategory requires the remote pilot to keep the UAS at least 30 m horizontally from uninvolved people, with the distance reduced to 5 m only when the aircraft is flying in low-speed mode. This distance is a legal limit, not advisory guidance. Flying closer without low-speed mode breaches the conditions of the subcategory.

Question 34Airspace restrictions and UAS geographical zones

Who can authorise a UAS flight inside an aerodrome flight restriction zone?

  1. The CAA's UAS department
  2. The aerodrome's air traffic control unit or operator Correct answer.
  3. The local police force
  4. The nearest Royal Air Force station

Explanation

Permission to operate inside a flight restriction zone is granted by the aerodrome whose zone it is, normally through its air traffic control unit or, where there is no ATC service, the aerodrome operator. The CAA and the police do not issue routine permissions for entry into an FRZ. Permission may come with conditions on height, location or timing.

Question 35Airspace restrictions and UAS geographical zones

What is the maximum height above the surface at which an Open category UAS may normally be flown in the UK?

  1. 500 ft
  2. 120 m Correct answer.
  3. 400 m
  4. 150 m

Explanation

Open category operations are limited to 120 m above the surface, which is approximately 400 ft. This ceiling applies unless a specific authorisation or a different rule for a defined zone says otherwise. Exceeding it takes the flight outside the Open category.

Question 36Airspace restrictions and UAS geographical zones

Which body is responsible for publishing UAS geographical zones in the UK?

  1. The Met Office
  2. The Health and Safety Executive
  3. The Air Accidents Investigation Branch
  4. The Civil Aviation Authority Correct answer.

Explanation

UAS geographical zones are established and published under the UAS regulatory framework, and in the UK this is done through the Civil Aviation Authority. These zones set out where UAS operations are prohibited, restricted or subject to conditions. Other bodies listed do not publish airspace restriction data.

Question 37Airspace restrictions and UAS geographical zones

Which activity is prohibited in the Open category regardless of the subcategory being flown?

  1. Flying over an assembly of people Correct answer.
  2. Flying in Class G airspace
  3. Flying in a built-up area in the A2 subcategory
  4. Flying at a height of 100 m

Explanation

No Open category flight may be made over an assembly of people, because a dense crowd cannot move out of the way if something goes wrong. Flying at 100 m is within the 120 m ceiling, and Class G airspace is uncontrolled and available subject to the other limits. The A2 subcategory is specifically designed to allow operations closer to built-up areas.

Question 38Airspace restrictions and UAS geographical zones

An A2 CofC holder plans to fly in Class G airspace well away from any aerodrome. What permission is required for the use of that airspace?

  1. Permission from the local authority
  2. A written exemption from the CAA
  3. Permission from the area control centre
  4. None, provided the Open category limits are respected Correct answer.

Explanation

Class G airspace is uncontrolled, so no air traffic permission is needed to fly there in the Open category, provided the height limit, distance rules and any geographical zone restrictions are respected. Controlled airspace and flight restriction zones are where specific permissions apply. Local authorities do not grant airspace permissions.

Question 39Airspace restrictions and UAS geographical zones

A flight is planned inside a Class D control zone but outside any flight restriction zone. What must the remote pilot do?

  1. Fly only above 120 m to stay clear of other traffic
  2. Nothing, because Class D airspace is uncontrolled
  3. Obtain permission from the controlling air traffic unit Correct answer.
  4. Notify the CAA at least 24 hours in advance

Explanation

Class D is controlled airspace, and Open category flights may not be made in controlled airspace without permission from the responsible air traffic control unit. Being outside an FRZ does not remove the need for that permission. Flying higher would both breach the 120 m limit and increase conflict with manned traffic.

Question 40Airspace restrictions and UAS geographical zones

Under what circumstance may an A2 CofC holder reduce the horizontal separation from uninvolved people to 5 m?

  1. When the UAS is being flown in low-speed mode Correct answer.
  2. Whenever the flight takes place in a rural area
  3. Whenever the aircraft is flown below 50 m
  4. When the flight lasts less than 10 minutes

Explanation

The reduced distance of 5 m is permitted only when the aircraft is operating in low-speed mode, which limits its kinetic energy and therefore the harm it could cause. Height, location and flight duration do not change the required separation. Outside low-speed mode the 30 m minimum applies.

Question 41Airspace restrictions and UAS geographical zones

You intend to fly inside the flight restriction zone of a small aerodrome that has no air traffic control service. Who should you approach for permission?

  1. The national area control centre
  2. The CAA's airspace regulation team
  3. The nearest police air operations unit
  4. The aerodrome operator Correct answer.

Explanation

Where an aerodrome has no air traffic control unit, permission to fly in its flight restriction zone is sought from the aerodrome operator, who is responsible for the zone. The absence of an ATC service does not remove the restriction or make the zone available by default. National bodies do not handle routine FRZ permissions.

Question 42Airspace restrictions and UAS geographical zones

A chart shows a danger area along your planned route. What does this indicate?

  1. The area is guaranteed safe for UAS at all times
  2. The area is reserved exclusively for military drones
  3. Flight is permanently prohibited for all aircraft
  4. Hazardous activity may take place there, so you should check whether it is active Correct answer.

Explanation

A danger area identifies airspace in which activities hazardous to aircraft may take place, often only at certain times, so the pilot must establish whether it is active before entering. It is not a permanent prohibition, unlike a prohibited area. Neither is it a guarantee of safety when the activity is running.

Question 43Airspace restrictions and UAS geographical zones

A major airshow is taking place about 20 km from your planned flight area. What is the most likely airspace consequence for your flight?

  1. Temporary restrictions may be notified by NOTAM, which you must check Correct answer.
  2. The entire flight information region is closed to all traffic
  3. UAS are automatically permitted because they are not display aircraft
  4. None, because airshows never affect airspace outside the venue

Explanation

Large displays and events commonly generate temporary airspace restrictions, published by NOTAM, which can extend well beyond the display site itself. The remote pilot must check for such notices before flying. Whole FIRs are not closed for a display, and there is no automatic permission for UAS.

Question 44Airspace restrictions and UAS geographical zones

You arrive at a site and find an emergency incident under way with police and ambulance crews in attendance. What is the correct course of action?

  1. Ask a member of the public to act as a visual observer while you fly
  2. Do not fly, and follow any instructions given by the emergency services Correct answer.
  3. Launch from inside the cordon and stay below 30 m
  4. Fly at 120 m so the aircraft stays well above the incident

Explanation

An emergency incident creates a hazard to aircraft and may be protected by a temporary restriction, and the emergency services may direct that no flying takes place. The remote pilot must not interfere with the response and should move on or wait. Neither height nor the use of an observer legitimises flying over or near an ongoing incident.

Question 45Airspace restrictions and UAS geographical zones

How is an 'assembly of people' best described for the purposes of UAS operations?

  1. A gathering so dense that people cannot readily move away Correct answer.
  2. Any group of two or more people
  3. Any gathering that includes the pilot's own support crew
  4. Only ticketed events inside an enclosed stadium

Explanation

The concept turns on density: people in such a crowd are unable to move out of the way promptly if a UAS fails or descends. Small dispersed groups and the pilot's own crew are not assemblies in this sense. The rule is not limited to ticketed or enclosed events.

Question 46Airspace restrictions and UAS geographical zones

An aerodrome's flight restriction zone applies at what times?

  1. Only during published operating hours
  2. Only when an air traffic control service is on duty
  3. Only when a daily NOTAM activates it
  4. At all times, whether or not the aerodrome is currently operating Correct answer.

Explanation

The flight restriction zone is a standing restriction; it exists continuously and does not switch off outside operating hours or when the tower is unmanned. Aircraft can still arrive or depart outside scheduled hours, and the zone protects them. A NOTAM may add restrictions but is not needed to bring the FRZ into force.

Question 47Airspace restrictions and UAS geographical zones

What does holding an A2 CofC give the holder in relation to restricted airspace?

  1. It removes the need to check NOTAMs
  2. Nothing extra; the relevant permission is still required Correct answer.
  3. It allows flight in any flight restriction zone below 120 m
  4. It allows flight in controlled airspace within 5 km of an aerodrome

Explanation

The A2 CofC is a competence certificate for the A2 subcategory; it confers no airspace access rights. Entry into a flight restriction zone or controlled airspace still requires permission from the responsible airspace authority. Checking NOTAMs remains obligatory on every flight.

Question 48Airspace restrictions and UAS geographical zones

Which of the following is a recognised purpose for establishing a UAS geographical zone?

  1. Allowing UAS to fly above 120 m in cities
  2. Reserving airspace exclusively for model aircraft clubs
  3. Transferring liability for collisions to the state
  4. Protecting security, privacy, the environment or public safety Correct answer.

Explanation

UAS geographical zones exist to protect safety, security, privacy, the environment and other public interests by prohibiting, restricting or conditioning UAS operations in defined areas. They are not a tool for granting altitude exemptions or shifting liability. Reserving airspace for a single user group is not their purpose.

Question 49Airspace restrictions and UAS geographical zones

What is meant by a 'dynamic' UAS geographical zone?

  1. A zone that exists only at weekends
  2. A zone that moves with the aircraft's position in flight
  3. A zone whose boundaries are set by the pilot
  4. A zone whose status or conditions change over time and is notified accordingly Correct answer.

Explanation

A dynamic zone is one whose activation or conditions vary over time, for example being switched on for an event or an emergency, with the current status made available to users. Its geometry is fixed by the authority, not by the pilot, and it does not follow the aircraft. Because the status changes, the pilot must check it shortly before flight.

Question 50Airspace restrictions and UAS geographical zones

How is an aerodrome flight restriction zone best described within the UK UAS framework?

  1. A voluntary advisory area with no legal force
  2. A danger area activated only during flying displays
  3. A U-space service area limited to commercial operators
  4. A UAS geographical zone in which operations are restricted unless permission is given Correct answer.

Explanation

Flight restriction zones are published as UAS geographical zones, meaning that UAS operations within them are prohibited or subject to conditions such as a requirement for permission. Breaching one is an offence rather than a matter of good practice. They apply to all UAS operators, not only commercial ones.
