Question 1Air law, air traffic rules and procedures

Under ICAO rules, which class of airspace is generally designated as controlled airspace in which IFR and VFR flights are both permitted and all flights receive air traffic control service?

  1. Class F airspace
  2. Class C airspace Correct answer.
  3. Class G airspace
  4. Class E airspace

Explanation

Class C is controlled airspace where both IFR and VFR flights are permitted, all receive ATC service, and IFR is separated from VFR while VFR is separated from IFR. Class E also permits both but VFR does not receive separation from other VFR.

Question 2Air law, air traffic rules and procedures

An RPA is being flown at 250 ft AGL within 3 km of a controlled aerodrome. What is the normal requirement before flight?

  1. A flight plan filed with the nearest meteorological office
  2. An air traffic control clearance or authorization from the aerodrome operator Correct answer.
  3. No notification is required if the RPA stays below 400 ft
  4. Permission from the local police station

Explanation

Operations near controlled aerodromes normally require an ATC clearance or authorization from the responsible authority because the RPA enters airspace where controlled traffic operates. Staying below 400 ft does not by itself remove this requirement near a controlled aerodrome.

Question 3Air law, air traffic rules and procedures

Which document contains the standards and recommended practices for rules of the air at the international level?

  1. ICAO Annex 17
  2. ICAO Annex 10
  3. ICAO Annex 14
  4. ICAO Annex 2 Correct answer.

Explanation

ICAO Annex 2, Rules of the Air, sets out the international standards and recommended practices for rules of the air. Annex 14 covers aerodromes, Annex 17 covers security, and Annex 10 covers aeronautical telecommunications.

Question 4Air law, air traffic rules and procedures

What is the standard maximum altitude above ground level at which a small RPA may normally be flown without special authorization?

  1. 250 ft
  2. 500 ft
  3. 400 ft Correct answer.
  4. 100 ft

Explanation

Most regulatory frameworks set 400 ft (about 120 m) AGL as the default ceiling for routine RPA operations. Higher flight requires specific authorization because it increases conflict risk with manned aircraft.

Question 5Air law, air traffic rules and procedures

Two RPA are converging head-on at the same altitude. Which avoidance rule applies?

  1. The faster aircraft has right of way
  2. The aircraft on the left has right of way
  3. Both must climb to different altitudes
  4. Both must turn to the right Correct answer.

Explanation

For head-on convergence, each aircraft alters course to the right so they pass port side to port side. This mirrors the manned-aircraft rule and provides predictable separation.

Question 6Air law, air traffic rules and procedures

An RPA operator plans a flight in Class G airspace away from any aerodrome. Which statement best describes the ATC service available?

  1. No ATC clearance is required and separation is the pilot's responsibility Correct answer.
  2. VFR flight is not permitted in Class G
  3. IFR traffic is prohibited in Class G
  4. Full separation from all other traffic is provided

Explanation

Class G is uncontrolled airspace, so no ATC clearance is required and traffic separation is not provided; the remote pilot must see and avoid. Both IFR and VFR may operate there subject to national rules.

Question 7Air law, air traffic rules and procedures

Which signal indicates that an aircraft on the ground should stop?

  1. A steady red light Correct answer.
  2. A flashing green light
  3. A flashing white light
  4. A steady green light

Explanation

A steady red light directed at an aircraft on the ground means stop. A steady green light means cleared for takeoff or to proceed, and flashing signals carry different meanings.

Question 8Air law, air traffic rules and procedures

When must an RPA remote pilot give way to a manned aircraft?

  1. Only when the manned aircraft is larger
  2. Only when the manned aircraft is on final approach
  3. Only inside controlled airspace
  4. At all times, regardless of the right-of-way rules Correct answer.

Explanation

RPA must always give way to manned aircraft; the remote pilot cannot assume the manned pilot has seen the RPA. This conservative rule reduces the risk of mid-air collision.

Question 9Air law, air traffic rules and procedures

What does a flashing red light directed at an aircraft in flight mean?

  1. Cleared to land
  2. Give way and continue circling
  3. Airport unsafe, do not land Correct answer.
  4. Return for landing

Explanation

A flashing red light to an aircraft in flight means the aerodrome is unsafe and landing is prohibited. A steady red light means give way and continue circling.

Question 10Air law, air traffic rules and procedures

Which of the following best describes the purpose of a NOTAM?

  1. To register the RPA with the authority
  2. To notify pilots of temporary changes or hazards affecting flight operations Correct answer.
  3. To record the pilot's flight hours
  4. To certify the airworthiness of an RPA

Explanation

A NOTAM (Notice to Air Missions) informs pilots of temporary or permanent changes and hazards such as closed runways, temporary restricted areas, or unserviceable navigation aids. It is a time-critical operational notice.

Question 11Air law, air traffic rules and procedures

An RPA is approaching a non-towered aerodrome to land. Which traffic pattern direction should normally be used?

  1. Either direction at the pilot's discretion
  2. The direction of the nearest runway threshold
  3. Left-hand pattern unless otherwise published Correct answer.
  4. Right-hand pattern unless otherwise published

Explanation

The standard traffic pattern at an aerodrome is left-hand unless a right-hand pattern is specifically published. This standard reduces conflict by making traffic behavior predictable.

Question 12Air law, air traffic rules and procedures

What is the meaning of the term 'ceiling' as used in aviation weather and flight planning?

  1. The upper limit of controlled airspace
  2. The height of the lowest broken or overcast cloud layer Correct answer.
  3. The maximum altitude of the RPA
  4. The maximum range of the control link

Explanation

Ceiling is the height above ground or water of the lowest layer of cloud reported as broken or overcast. It is a key factor in determining whether visual flight conditions exist.

Question 13Air law, air traffic rules and procedures

An RPA is flying in visibility of 2 km. Under typical small-RPA operating rules, what is the usual minimum flight visibility requirement?

  1. No minimum applies
  2. 1 km
  3. 5 km Correct answer.
  4. 500 m

Explanation

Typical small-RPA rules require flight visibility of at least 5 km and clear of cloud with the remote pilot able to see the aircraft. Operating in 2 km visibility would not meet this standard.

Question 14Air law, air traffic rules and procedures

What is the primary purpose of a transponder in airspace where it is required?

  1. To allow ATC to identify and track the aircraft by radar Correct answer.
  2. To record flight data for maintenance
  3. To stabilize the RPA in turbulence
  4. To provide electrical power to the RPA

Explanation

A transponder replies to radar interrogations, giving ATC the aircraft's identity and altitude so it can be tracked and separated. Certain airspace requires an operable transponder with altitude reporting.

Question 15Air law, air traffic rules and procedures

Which of the following is a restricted area?

  1. Airspace where only IFR flight is permitted
  2. Airspace where flight is prohibited for safety or security reasons Correct answer.
  3. Airspace designated for glider operations only
  4. Airspace where ATC provides advisory service

Explanation

A restricted area is airspace within which flight is prohibited or restricted, often for safety or security reasons. Entry usually requires specific permission from the controlling authority.

Question 16Air law, air traffic rules and procedures

An RPA is overtaking another RPA from behind at the same altitude. Which aircraft has right of way?

  1. The aircraft being overtaken Correct answer.
  2. The aircraft with the higher registration number
  3. Neither; both must descend
  4. The overtaking aircraft

Explanation

The aircraft being overtaken has right of way, and the overtaking aircraft must keep clear. This follows the general right-of-way principle applied to converging traffic.

Question 17Air law, air traffic rules and procedures

What does a steady green light directed at an aircraft in flight mean?

  1. Give way and continue circling
  2. Airport unsafe, do not land
  3. Cleared to land Correct answer.
  4. Return to starting point on the aerodrome

Explanation

A steady green light to an aircraft in flight means it is cleared to land. Other steady and flashing signals carry distinct meanings for ground and airborne aircraft.

Question 18Air law, air traffic rules and procedures

Why must an RPA remote pilot maintain direct visual contact with the RPA during flight?

  1. To improve the video downlink quality
  2. To comply with radio licensing rules
  3. To see and avoid other aircraft and obstacles Correct answer.
  4. To reduce battery consumption

Explanation

Visual line of sight allows the remote pilot to detect and avoid other aircraft, persons, and obstacles that may not appear on a video feed. It is a core safety requirement in most RPA regulations.

Question 19Air law, air traffic rules and procedures

An RPA operator intends to fly within a prohibited area. What is the normal requirement?

  1. A radio check with the nearest tower
  2. No requirement if the flight is below 400 ft
  3. A NOTAM filed at least 24 hours in advance
  4. Specific permission from the authority responsible for the area Correct answer.

Explanation

Prohibited areas forbid flight unless specific permission is granted by the responsible authority. Operating below a certain altitude does not override the prohibition.

Question 20Air law, air traffic rules and procedures

What is the standard unit of speed used in aviation for reporting aircraft speed?

  1. Knots Correct answer.
  2. Metres per second
  3. Kilometres per hour
  4. Miles per hour

Explanation

Aviation uses knots (nautical miles per hour) as the standard unit for speed. Altitudes are typically reported in feet and distances in nautical miles.

Question 21Air law, air traffic rules and procedures

An RPA is flying at 300 ft AGL when a manned helicopter appears on a converging path. What should the remote pilot do?

  1. Accelerate to pass in front of the helicopter
  2. Give way to the helicopter and maneuver clear of its path Correct answer.
  3. Maintain course and altitude because the RPA has right of way
  4. Climb rapidly to pass above the helicopter

Explanation

The RPA must give way to the manned aircraft. The remote pilot should maneuver clear in a predictable manner rather than assuming the helicopter will avoid the RPA.

Question 22Air law, air traffic rules and procedures

Which of the following best describes a controlled aerodrome?

  1. An aerodrome without any radio communication
  2. An aerodrome with a paved runway only
  3. An aerodrome open only to scheduled airlines
  4. An aerodrome where air traffic control service is provided to aerodrome traffic Correct answer.

Explanation

A controlled aerodrome is one where air traffic control service is provided to aerodrome traffic, meaning clearances are required for movements. The presence of a control tower is typical but the defining feature is the ATC service.

Question 23Air law, air traffic rules and procedures

What is the purpose of a clearance delivered by ATC to an RPA operating in controlled airspace?

  1. To confirm the RPA's battery status
  2. To assign the RPA a registration number
  3. To verify the remote pilot's medical fitness
  4. To authorize the flight under specified conditions and provide separation Correct answer.

Explanation

An ATC clearance authorizes a flight under specified conditions and allows ATC to provide separation from other traffic. It is not a technical or administrative approval.

Question 24Air law, air traffic rules and procedures

An RPA remote pilot observes another aircraft on a collision course but cannot determine its type. What is the safest action?

  1. Maneuver early and clearly to increase separation Correct answer.
  2. Continue and rely on the other aircraft to maneuver
  3. Reduce altitude rapidly to pass below
  4. Turn off the control link to avoid interference

Explanation

When the other aircraft's intentions are unknown, the remote pilot should maneuver early and clearly to increase separation. Predictable, timely action reduces the risk of a mid-air collision.

Question 25Air law, air traffic rules and procedures

Which of the following statements about the 'see and avoid' principle is correct?

  1. It requires the remote pilot to detect and avoid other traffic and hazards visually Correct answer.
  2. It applies only to manned aircraft
  3. It is replaced by ADS-B in all airspace
  4. It applies only at night

Explanation

See and avoid requires the pilot to visually detect other traffic and hazards and take timely action to avoid them. For RPA this is closely tied to maintaining visual line of sight.

Question 26Air law, air traffic rules and procedures

Under the standard ICAO rules of the air, what is the general right-of-way rule when two aircraft are approaching head-on at the same altitude?

  1. The aircraft with the lower performance gives way
  2. The faster aircraft maintains its track
  3. Both aircraft alter heading to the right Correct answer.
  4. Both aircraft climb to separate vertically

Explanation

When two aircraft are approaching head-on or nearly so and there is a risk of collision, each shall alter its heading to the right. This creates a predictable, mutual separation action rather than relying on one party to yield.

Question 27Air law, air traffic rules and procedures

In general aviation practice, how are altitudes above mean sea level normally expressed on an altimeter when flying below the transition altitude?

  1. As flight levels
  2. As altitude in feet Correct answer.
  3. As height above ground
  4. As pressure altitude in hectopascals

Explanation

Below the transition altitude, aircraft typically report altitude, which is height above mean sea level in feet with the altimeter set to local pressure. Flight levels are used at and above the transition altitude.

Question 28Air law, air traffic rules and procedures

What is the meaning of the term 'transition altitude' in air traffic operations?

  1. The altitude below which position reports are not required
  2. The altitude at or below which the vertical position is expressed as altitude Correct answer.
  3. The altitude at which an aircraft must switch to a transponder
  4. The altitude at which an RPA must begin its descent

Explanation

The transition altitude is the altitude at or below which the vertical position of an aircraft is controlled by reference to altitudes. Above it, flight levels are used.

Question 29Air law, air traffic rules and procedures

An RPA is being operated at night within a control zone. Which practice best supports compliance with air traffic rules in this situation?

  1. Operating without any lighting provided the RPA stays below 100 ft
  2. Relying only on the RPA's onboard navigation lights Correct answer.
  3. Using a strobe only when crossing runway centrelines
  4. Switching off lights to avoid dazzling other pilots

Explanation

At night, anti-collision and navigation lighting helps other traffic and ATC identify the RPA. Operating without adequate lighting reduces conspicuity and is not acceptable in controlled airspace.

Question 30Air law, air traffic rules and procedures

What is the primary function of an air traffic control tower at a controlled aerodrome?

  1. Providing weather forecasts for the region
  2. Registering RPA ownership records
  3. Issuing clearances and separating traffic in the vicinity of the aerodrome Correct answer.
  4. Maintaining the aerodrome's runway lighting

Explanation

A control tower provides aerodrome control service, issuing clearances and separating aircraft operating on and around the aerodrome. Weather forecasting and aerodrome maintenance are separate functions.

Question 31Air law, air traffic rules and procedures

An RPA remote pilot wishes to enter controlled airspace. What is normally required before entry?

  1. An ATC clearance obtained before entering Correct answer.
  2. A radio call after entering the airspace
  3. Notification to the nearest police station
  4. A written log entry filed after the flight

Explanation

Entry into controlled airspace requires an ATC clearance obtained before entry. Entering first and calling afterwards is not acceptable because separation is not assured.

Question 32Air law, air traffic rules and procedures

Which phrase best describes the purpose of a control zone (CTR)?

  1. Airspace where no radio communication is required
  2. Airspace surrounding an aerodrome within which special rules apply to protect traffic Correct answer.
  3. Airspace reserved only for military operations
  4. Airspace used exclusively for parachute operations

Explanation

A control zone is controlled airspace extending around an aerodrome to protect traffic in the vicinity. It is not reserved for a single user type.

Question 33Air law, air traffic rules and procedures

An RPA is flying near a non-towered aerodrome and sees a manned aircraft on final approach. What should the remote pilot do?

  1. Give way to the manned aircraft and remain clear of the approach path Correct answer.
  2. Land immediately on the nearest taxiway
  3. Continue the flight path and expect the manned aircraft to adjust
  4. Climb above the manned aircraft's approach path

Explanation

An RPA must give way to manned aircraft, and remaining clear of an approach path is the safest way to do so. Continuing or climbing could create a conflict.

Question 34Air law, air traffic rules and procedures

What does a red pyrotechnic signal fired from the ground towards an aircraft in flight indicate?

  1. That the aircraft should continue its current approach
  2. That the aircraft should switch to a different radio frequency
  3. That the aircraft should not land for the time being Correct answer.
  4. That the aircraft should give way and continue

Explanation

A red pyrotechnic signal directed at an aircraft in flight means that landing is not permitted for the time being. The pilot should remain clear and await further instructions.

Question 35Air law, air traffic rules and procedures

An RPA remote pilot observes an unmarked tethered balloon in the vicinity. Which action best reflects good airmanship?

  1. Maintain a safe lateral and vertical distance from the object Correct answer.
  2. Pass directly underneath the balloon
  3. Assume the balloon is stationary and ignore it
  4. Fly closer to identify the object

Explanation

Tethered balloons and similar obstacles may have mooring lines that are difficult to see. Maintaining a generous distance avoids entanglement and collision.

Question 36Air law, air traffic rules and procedures

Which document normally contains the rules and procedures governing air traffic in a particular State?

  1. The aircraft maintenance manual
  2. The RPA battery log
  3. The manufacturer's quick-start guide
  4. The State's aeronautical information publication Correct answer.

Explanation

The aeronautical information publication (AIP) contains the rules, procedures, and aeronautical data for a State. Maintenance manuals and operator logs do not define air traffic rules.

Question 37Air law, air traffic rules and procedures

What does a white cross displayed on a runway or apron indicate to pilots?

  1. That the area is available for landing
  2. That the area is unfit for use by aircraft Correct answer.
  3. That the area has recently been resurfaced
  4. That the area is reserved for gliders

Explanation

A white cross marks an area that is unfit for use by aircraft, for example a closed runway or apron. Pilots should avoid using it.

Question 38Air law, air traffic rules and procedures

An RPA is being flown in airspace where a transponder Mode C is required. What information does Mode C primarily provide?

  1. Fuel remaining
  2. Ground speed
  3. Aircraft identification
  4. Pressure altitude information Correct answer.

Explanation

Mode C reports pressure altitude to ATC, enabling altitude-based separation. Identification is normally provided by Mode A or Mode S data.

Question 39Air law, air traffic rules and procedures

What is the meaning of the term 'ATS route' in air navigation?

  1. A route designated for air traffic service purposes Correct answer.
  2. A route used exclusively for training flights
  3. A route defined by ground-based radar coverage
  4. A route followed only by military aircraft

Explanation

An ATS route is a specified route established for the purpose of providing air traffic services. It is not limited to a single user category.

Question 40Air law, air traffic rules and procedures

An RPA remote pilot intends to operate in a danger area that is active. Which action is most appropriate?

  1. Enter the area and monitor the radio only
  2. Obtain information on activity and avoid the area if it is active Correct answer.
  3. Enter the area at a higher altitude to reduce risk
  4. Proceed because danger areas are always advisory

Explanation

Danger areas contain activity that may be hazardous, such as firing or testing. The remote pilot should check the status and avoid the area when it is active.

Question 41Air law, air traffic rules and procedures

What does a yellow and black striped marker board at an aerodrome normally indicate?

  1. A taxiway holding position Correct answer.
  2. A runway threshold
  3. A wind direction indicator
  4. A designated parking area

Explanation

Yellow and black markings are typically used to identify holding positions on taxiways. They help pilots stop clear of runways and other protected areas.

Question 42Air law, air traffic rules and procedures

An RPA is operating in Class D airspace. Which statement best describes the typical ATC service provided?

  1. Traffic information is provided to VFR aircraft and separation to IFR aircraft Correct answer.
  2. No service is provided to any aircraft
  3. Only weather information is provided
  4. Separation is provided between all IFR and VFR traffic

Explanation

In Class D airspace, ATC provides separation between IFR flights and traffic information to VFR flights. Full separation between all aircraft is not normally provided.

Question 43Air law, air traffic rules and procedures

Which of the following best describes the purpose of a 'flight plan' filed before a flight?

  1. To certify the airworthiness of the aircraft
  2. To authorise the sale of the aircraft
  3. To provide advance notification of the flight to air traffic services Correct answer.
  4. To record the pilot's medical status

Explanation

A flight plan provides air traffic services with advance information about the intended flight. It supports alerting and coordination but does not certify airworthiness.

Question 44Air law, air traffic rules and procedures

An RPA remote pilot hears an ATC instruction that is unclear. What is the correct course of action?

  1. Assume the instruction is correct and continue
  2. Ask ATC to repeat or clarify the instruction Correct answer.
  3. Read back the instruction as understood and proceed
  4. Switch off the radio to avoid confusion

Explanation

When an instruction is unclear, the pilot should request clarification or repetition before acting. Proceeding on an assumption risks non-compliance and collision.

Question 45Air law, air traffic rules and procedures

Which condition normally applies to the use of a standard holding pattern at a non-towered aerodrome?

  1. Turns are made to the left unless specified otherwise
  2. Holding is only permitted above 5000 ft
  3. No turns are permitted
  4. Turns are made to the right unless specified otherwise Correct answer.

Explanation

Standard holding patterns use right-hand turns unless otherwise specified. Left-hand patterns are exceptions that must be published or instructed.

Question 46Air law, air traffic rules and procedures

What is the primary purpose of a runway holding position marking?

  1. To indicate where an aircraft should stop before entering a runway Correct answer.
  2. To mark the centre of the runway
  3. To indicate the maximum aircraft weight
  4. To show the touchdown zone

Explanation

Runway holding position markings show where an aircraft must stop short of a runway until cleared to enter. They protect the runway strip from incursions.

Question 47Air law, air traffic rules and procedures

An RPA is flying in a control zone when the remote pilot loses radio communication with ATC. What is the most appropriate initial action?

  1. Attempt to re-establish communication and follow the applicable lost-communication procedure Correct answer.
  2. Continue the flight as planned without informing anyone
  3. Immediately climb to a higher altitude
  4. Turn off the RPA's transponder

Explanation

The remote pilot should try to restore communication and follow the published lost-communication procedure. Continuing blindly or climbing without coordination increases risk.

Question 48Air law, air traffic rules and procedures

Which statement best describes the meaning of 'clearance limit' in an ATC clearance?

  1. The point to which an aircraft is cleared to proceed Correct answer.
  2. The maximum altitude an aircraft may reach
  3. The time by which an aircraft must land
  4. The minimum fuel required for the flight

Explanation

The clearance limit is the point to which an aircraft is cleared to proceed under its current clearance. Further clearance is required beyond that point.

Question 49Air law, air traffic rules and procedures

An RPA operator is planning a flight near an active glider site. Which consideration is most relevant to air traffic rules?

  1. Gliders are prohibited from operating below 3000 ft
  2. Gliders always have right of way over all other aircraft
  3. Gliders may operate in the area and the RPA must remain clear Correct answer.
  4. Gliders must announce their position on the RPA's control frequency

Explanation

Gliders may operate in the vicinity of a glider site, and other aircraft should remain clear of their activity. Right of way is not automatically granted to gliders over all traffic.

Question 50Air law, air traffic rules and procedures

What is the purpose of an aerodrome's 'wind direction indicator'?

  1. To provide radio communication coverage
  2. To indicate the runway in use
  3. To mark the aerodrome boundary
  4. To show the direction and approximate strength of the surface wind Correct answer.

Explanation

A wind direction indicator, such as a windsock, shows the surface wind direction and gives a rough indication of its strength. It does not designate the active runway.
