Question 1International law: ICAO Convention, Chicago Convention, annexes and international organisations

Under the Convention on International Civil Aviation (Chicago Convention), which body is the permanent governing organ of the International Civil Aviation Organization, meeting at least once every three years?

  1. The Secretariat
  2. The Assembly Correct answer.
  3. The Air Navigation Commission
  4. The Council

Explanation

The Assembly is the sovereign body of ICAO, composed of all contracting States, and it convenes not less than once every three years to set policy and approve budgets. The Council is the smaller permanent executive organ elected by the Assembly, so it does not meet as the full body of States.

Question 2International law: ICAO Convention, Chicago Convention, annexes and international organisations

Which ICAO organ is responsible for adopting Standards and Recommended Practices as Annexes to the Chicago Convention?

  1. The Legal Committee
  2. The Air Navigation Commission
  3. The Assembly
  4. The Council Correct answer.

Explanation

Under Article 54 of the Chicago Convention the Council adopts and amends Annexes containing Standards and Recommended Practices, and notifies contracting States of their adoption. The Assembly and technical commissions may propose or review material but do not hold the adopting power.

Question 3International law: ICAO Convention, Chicago Convention, annexes and international organisations

A State finds it impracticable to comply with an international Standard in an ICAO Annex. What does the Chicago Convention require that State to do?

  1. Publish the difference only in its own national aeronautical information publication
  2. Suspend the affected operations until full compliance is achieved
  3. Notify ICAO immediately of the difference between its practice and the Standard Correct answer.
  4. Request a waiver from the Council before resuming operations

Explanation

Article 38 of the Chicago Convention requires a State that finds it impracticable to comply with any international Standard to notify ICAO immediately of the differences between its own practice and that established by the Standard. Notification to ICAO is the core obligation, from which publication of the difference in the State's AIP then follows.

Question 4International law: ICAO Convention, Chicago Convention, annexes and international organisations

Which Annex to the Chicago Convention contains the Standards and Recommended Practices for Personnel Licensing?

  1. Annex 6
  2. Annex 1 Correct answer.
  3. Annex 8
  4. Annex 2

Explanation

Annex 1 to the Chicago Convention is titled Personnel Licensing and covers licences and ratings for flight crew, air traffic controllers and other aviation personnel. The other Annexes listed deal with different subjects, such as rules of the air or airworthiness.

Question 5International law: ICAO Convention, Chicago Convention, annexes and international organisations

Annex 19 to the Chicago Convention deals with which subject?

  1. Aircraft Accident and Incident Investigation
  2. Facilitation
  3. Safety Management Correct answer.
  4. Aviation Security

Explanation

Annex 19 is dedicated to Safety Management, establishing the framework for State Safety Programmes and safety management systems. Security is Annex 17, facilitation is Annex 9, and accident investigation is Annex 13.

Question 6International law: ICAO Convention, Chicago Convention, annexes and international organisations

Which Annex contains the Standards and Recommended Practices governing Aircraft Accident and Incident Investigation?

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

Explanation

Annex 13 sets out the international requirements for the investigation of aircraft accidents and incidents, including the rights and obligations of the State of Occurrence, State of Registry and State of Design and Manufacture. The neighbouring Annexes cover different fields such as search and rescue and aerodromes.

Question 7International law: ICAO Convention, Chicago Convention, annexes and international organisations

Under the Chicago Convention, each contracting State recognises the certificates of airworthiness and licences issued by other contracting States, provided that the requirements under which they were issued are equal to or above the minimum Standards established under the Convention. This principle is expressed in which Article?

  1. Article 1
  2. Article 44
  3. Article 5
  4. Article 33 Correct answer.

Explanation

Article 33 embodies the mutual recognition principle: certificates of airworthiness and licences issued by one contracting State are recognised by others if their issuing requirements meet or exceed the minimum Standards. Article 1 states sovereignty over airspace, Article 5 concerns non-scheduled flights, and Article 44 sets out ICAO's aims and objectives.

Question 8International law: ICAO Convention, Chicago Convention, annexes and international organisations

Which Article of the Chicago Convention confirms that every State has complete and exclusive sovereignty over the airspace above its territory?

  1. Article 6
  2. Article 1 Correct answer.
  3. Article 12
  4. Article 9

Explanation

Article 1 states the foundational principle that contracting States recognise the complete and exclusive sovereignty of every State over the airspace above its territory. This principle underpins the requirement for permission before scheduled international air services may operate.

Question 9International law: ICAO Convention, Chicago Convention, annexes and international organisations

Under Article 6 of the Chicago Convention, scheduled international air services may be operated over or into the territory of a contracting State only with the special permission or other authorisation of that State. This requirement is the basis for which type of bilateral arrangement?

  1. Air Services Agreements Correct answer.
  2. Technical standardisation arrangements
  3. Search and rescue coordination agreements
  4. Aircraft registration conventions

Explanation

Because Article 6 requires specific permission for scheduled services, States conclude bilateral Air Services Agreements that grant route rights, capacity entitlements and traffic rights. These agreements are the practical mechanism through which the Article 6 permission is given.

Question 10International law: ICAO Convention, Chicago Convention, annexes and international organisations

The 'Five Freedoms of the Air' are commonly associated with which instrument?

  1. The Tokyo Convention
  2. The Paris Convention of 1919
  3. The International Air Services Transit Agreement Correct answer.
  4. The Warsaw Convention

Explanation

The International Air Services Transit Agreement, adopted together with the Chicago Convention in 1944, grants the first two freedoms (overflight and technical stops) to participating States, and the wider group of five freedoms is conventionally discussed in that framework. The Warsaw and Tokyo Conventions deal with liability and offences on board respectively.

Question 11International law: ICAO Convention, Chicago Convention, annexes and international organisations

Under the Chicago Convention, what is the nationality of an aircraft for international purposes?

  1. The nationality of the operator company
  2. The nationality of the State in which the aircraft is registered Correct answer.
  3. The nationality of the State where the aircraft was manufactured
  4. The nationality of the pilot in command

Explanation

Article 17 provides that aircraft have the nationality of the State in which they are registered, and an aircraft cannot be validly registered in more than one State under Article 18. The operator's, pilot's or manufacturer's nationality does not determine the aircraft's nationality.

Question 12International law: ICAO Convention, Chicago Convention, annexes and international organisations

Under Article 12 of the Chicago Convention, an aircraft flying over the high seas is subject to which rules of the air?

  1. The rules established under the Convention, that is the Standards in Annex 2 Correct answer.
  2. The rules of the State of Registry only
  3. The rules of the State of the operator only
  4. The rules of the nearest coastal State

Explanation

Article 12 requires States to keep their rules of the air uniform to the greatest possible extent and provides that over the high seas the rules in force are those established under the Convention, namely the Standards of Annex 2. National rules of the State of Registry apply over its own territory, not over the high seas.

Question 13International law: ICAO Convention, Chicago Convention, annexes and international organisations

A contracting State wishes to prohibit flights over a particular area of its territory for military reasons. Which Article of the Chicago Convention provides the basis for such a restriction?

  1. Article 15
  2. Article 10
  3. Article 13
  4. Article 9 Correct answer.

Explanation

Article 9 allows a State, on grounds of military necessity or public safety, to restrict or prohibit uniformly the aircraft of other States from flying over certain areas of its territory, subject to conditions on notification and non-discrimination. Article 10 concerns landing at customs airports, Article 13 concerns entry and clearance regulations, and Article 15 concerns airport charges.

Question 14International law: ICAO Convention, Chicago Convention, annexes and international organisations

Which organisation was established by the Convention on Offences and Certain Other Acts Committed on Board Aircraft to address jurisdiction over offences aboard aircraft?

  1. The Tokyo Convention framework Correct answer.
  2. The Montreal Convention framework
  3. The Geneva Convention framework
  4. The Rome Convention framework

Explanation

The Tokyo Convention of 1963 addresses offences and acts committed on board aircraft, including the powers of the aircraft commander and the jurisdiction of the State of Registry. The Rome Convention concerns surface damage, the Montreal Convention concerns carrier liability, and the Geneva Convention concerns recognition of rights in aircraft.

Question 15International law: ICAO Convention, Chicago Convention, annexes and international organisations

Which instrument governs the liability of the carrier for international carriage of passengers and baggage and consolidated earlier Warsaw-system rules?

  1. The Chicago Convention
  2. The Tokyo Convention
  3. The Cape Town Convention
  4. The Montreal Convention of 1999 Correct answer.

Explanation

The Montreal Convention of 1999 modernised and consolidated the Warsaw system, setting out carrier liability for death or injury, delay, baggage and cargo. It is separate from the Chicago Convention, which governs aviation regulation rather than carrier liability.

Question 16International law: ICAO Convention, Chicago Convention, annexes and international organisations

Which ICAO document type communicates mandatory requirements adopted by the Council that States must implement under the Convention?

  1. Standards and Recommended Practices in Annexes Correct answer.
  2. Training manuals distributed to approved organisations
  3. Guidance material published for information only
  4. Advisory circulars issued by the Secretariat

Explanation

Standards and Recommended Practices contained in Annexes are the formal instruments through which the Council sets international requirements. Standards are mandatory in character, while Recommended Practices are desirable, and guidance material and manuals are informational only.

Question 17International law: ICAO Convention, Chicago Convention, annexes and international organisations

In ICAO terminology, what distinguishes a Standard from a Recommended Practice?

  1. A Standard is binding on all States without exception, while a Recommended Practice is advisory
  2. A Standard is issued by the Assembly, while a Recommended Practice is issued by the Council
  3. A Standard is a specification whose uniform application is recognised as necessary, while a Recommended Practice is desirable but not essential Correct answer.
  4. A Standard applies only to commercial air transport, while a Recommended Practice applies to general aviation

Explanation

ICAO defines a Standard as a specification whose uniform application is recognised as necessary for the safety or regularity of international air navigation, and a Recommended Practice as one whose uniform application is recognised as desirable. Both are adopted by the Council, and States may file differences against either.

Question 18International law: ICAO Convention, Chicago Convention, annexes and international organisations

Which Annex contains the Standards relating to Aeronautical Charts?

  1. Annex 3
  2. Annex 4 Correct answer.
  3. Annex 10
  4. Annex 5

Explanation

Annex 4 is titled Aeronautical Charts and specifies the charts to be provided for international air navigation. Annex 3 covers meteorological services, Annex 5 covers units of measurement, and Annex 10 covers aeronautical telecommunications.

Question 19International law: ICAO Convention, Chicago Convention, annexes and international organisations

A State issues an airworthiness certificate to an aircraft but its certification requirements fall below the minimum Standards of Annex 8. What is the consequence under Article 33 of the Chicago Convention?

  1. Other contracting States may refuse recognition of the certificate Correct answer.
  2. The certificate becomes invalid worldwide immediately
  3. ICAO suspends the State's voting rights in the Assembly
  4. Other contracting States are automatically obliged to recognise the certificate

Explanation

Article 33 conditions recognition on the issuing requirements being equal to or above the minimum Standards established under the Convention. Where they fall below that level, other States are not obliged to recognise the certificate and may refuse it.

Question 20International law: ICAO Convention, Chicago Convention, annexes and international organisations

Which body of the ICAO Council structure is composed of experts nominated by contracting States and reviews technical proposals before they are submitted to the Council?

  1. The Legal Committee
  2. The Finance Committee
  3. The Committee on Unlawful Interference
  4. The Air Navigation Commission Correct answer.

Explanation

The Air Navigation Commission consists of persons nominated by contracting States and appointed by the Council, and it considers technical matters, including proposed amendments to the technical Annexes, before they go to the Council. The other bodies listed deal with legal, security or financial matters rather than technical Annex content.

Question 21International law: ICAO Convention, Chicago Convention, annexes and international organisations

Under the Chicago Convention, which State is responsible for ensuring that aircraft on its register comply with the rules of the air in force in the territory overflown?

  1. The State of the operator's principal place of business
  2. The State of Registry Correct answer.
  3. The State whose territory is overflown
  4. The State of departure

Explanation

Article 12 requires each contracting State to ensure that aircraft on its register, wherever they may be, comply with the rules of the air in force in the territory overflown. Enforcement of the rules against the aircraft therefore rests with the State of Registry.

Question 22International law: ICAO Convention, Chicago Convention, annexes and international organisations

Which Annex deals with Facilitation of the movement of persons and goods across national boundaries?

  1. Annex 9 Correct answer.
  2. Annex 15
  3. Annex 17
  4. Annex 11

Explanation

Annex 9 is titled Facilitation and covers formalities, documentation and procedures for the clearance of aircraft, passengers and cargo. Annex 11 covers air traffic services, Annex 15 aeronautical information services, and Annex 17 security.

Question 23International law: ICAO Convention, Chicago Convention, annexes and international organisations

The International Air Services Transit Agreement grants participating States which privileges for scheduled flights?

  1. The right to carry traffic between two foreign States
  2. The right to establish domestic cabotage services in another State
  3. The privilege to fly across territory without landing and to land for non-traffic purposes Correct answer.
  4. The right to operate without any notification to the overflown State

Explanation

The Transit Agreement grants the first and second freedoms, namely the privilege to fly across the territory of another party without landing and to land for non-traffic purposes such as refuelling. It does not grant traffic rights between foreign States or cabotage.

Question 24International law: ICAO Convention, Chicago Convention, annexes and international organisations

Article 7 of the Chicago Convention reserves cabotage to the national State. What does cabotage mean in this context?

  1. The carriage of traffic between two different States by a national carrier
  2. The carriage of traffic between two points within the territory of the same State by a foreign aircraft Correct answer.
  3. The transit of an aircraft through another State's airspace without landing
  4. The operation of non-scheduled flights for humanitarian purposes

Explanation

Cabotage refers to the carriage of traffic, such as passengers or cargo, between two points within the territory of a single State, and Article 7 reserves this to that State's own aircraft. It does not refer to international carriage between different States or to overflight.

Question 25International law: ICAO Convention, Chicago Convention, annexes and international organisations

Which ICAO organ elects the members of the Council and reviews the reports of the Council?

  1. The Assembly Correct answer.
  2. The Legal Committee
  3. The Air Navigation Commission
  4. The Secretariat

Explanation

The Assembly elects the contracting States to be represented on the Council and reviews the Council's reports and the organisation's work programme and budget. The other bodies are subordinate or advisory and do not elect the Council.

Question 26International law: ICAO Convention, Chicago Convention, annexes and international organisations

Which ICAO document is the formal legal instrument, opened for signature at Chicago in 1944, that established the International Civil Aviation Organization and replaced the earlier Paris and Havana arrangements?

  1. The Warsaw Convention
  2. The Protocol relating to the Neutrality of Aircraft
  3. The International Air Services Transit Agreement
  4. The Convention on International Civil Aviation Correct answer.

Explanation

The Convention on International Civil Aviation, signed at Chicago on 7 December 1944, created ICAO and set out the constitutional framework for international civil aviation. It superseded the Paris Convention of 1919 and the Havana Convention of 1928. The other instruments listed are separate treaties or agreements.

Question 27International law: ICAO Convention, Chicago Convention, annexes and international organisations

In which city is the headquarters of the International Civil Aviation Organization located?

  1. Paris
  2. Montreal Correct answer.
  3. New York
  4. Geneva

Explanation

ICAO's headquarters are in Montreal, Canada, where the Assembly and Council meet and where the Secretariat is based. Geneva hosts other international bodies but not ICAO's headquarters. New York is the seat of the United Nations Headquarters, and Paris is associated with the earlier Paris Convention and with other bodies such as EASA.

Question 28International law: ICAO Convention, Chicago Convention, annexes and international organisations

Which ICAO body meets at least once every three years and brings together delegates from all contracting States to set the organisation's broad policy and budget?

  1. The Council
  2. The Assembly Correct answer.
  3. The Legal Committee
  4. The Air Navigation Commission

Explanation

The Assembly is the sovereign body of ICAO, composed of delegates from all contracting States, and it convenes at least once every three years. It approves the budget, reviews the work of the Council and adopts resolutions. The Council is a smaller elected body, while the Air Navigation Commission and Legal Committee are subordinate technical and legal bodies.

Question 29International law: ICAO Convention, Chicago Convention, annexes and international organisations

Under the Chicago Convention, what is the principal consequence for a contracting State that fails to comply with an Annex Standard without notifying ICAO of a difference?

  1. The State's airworthiness certificates are automatically invalidated by the Council.
  2. The State's aircraft lose their nationality and may not be flown internationally.
  3. The State is automatically suspended from ICAO until the difference is filed.
  4. The State remains obliged to comply, and the difference is not published, so other States may assume full conformity. Correct answer.

Explanation

Article 38 requires a State that finds it impracticable to comply with any international Standard to notify ICAO of the difference, and ICAO then publishes it. If no difference is notified, other States are entitled to assume that the State conforms fully to the Standard. There is no automatic suspension or invalidation of certificates as a sanction.

Question 30International law: ICAO Convention, Chicago Convention, annexes and international organisations

Which ICAO Annex contains the Standards and Recommended Practices for the safe transport of dangerous goods by air?

  1. Annex 18 Correct answer.
  2. Annex 14
  3. Annex 17
  4. Annex 9

Explanation

Annex 18, The Safe Transport of Dangerous Goods by Air, contains the Standards and Recommended Practices for dangerous goods, with the detailed technical instructions published separately by ICAO. Annex 14 deals with aerodromes, Annex 17 with security and Annex 9 with facilitation.

Question 31International law: ICAO Convention, Chicago Convention, annexes and international organisations

Which ICAO Annex governs the licensing of flight crew and other aviation personnel?

  1. Annex 6
  2. Annex 2
  3. Annex 11
  4. Annex 1 Correct answer.

Explanation

Annex 1, Personnel Licensing, sets out the Standards and Recommended Practices for the licensing and medical fitness of flight crew, air traffic controllers and other aviation personnel. Annex 2 contains the Rules of the Air, Annex 6 covers operation of aircraft and Annex 11 covers air traffic services.

Question 32International law: ICAO Convention, Chicago Convention, annexes and international organisations

Under the Chicago Convention, which State is responsible for the licensing of a flight crew member and for ensuring that the licence meets the minimum Standards of Annex 1?

  1. The State of Registry of the aircraft flown
  2. The State of the aircraft manufacturer
  3. The State that issues the licence, normally the State of which the holder is a national Correct answer.
  4. The State of the operator

Explanation

Licences for flight crew are issued by the State whose nationality the person holds or by the State where the person is ordinarily resident, and that issuing State must ensure the licence meets Annex 1 Standards. Other States recognise these licences under Article 33, subject to the licence being equal to or above the minimum Standards. The State of Registry of the aircraft is not the licensing authority for the crew.

Question 33International law: ICAO Convention, Chicago Convention, annexes and international organisations

Which Article of the Chicago Convention requires aircraft engaged in international navigation to carry specified documents, including certificates of registration and airworthiness, crew licences and journey log books?

  1. Article 29 Correct answer.
  2. Article 35
  3. Article 26
  4. Article 21

Explanation

Article 29 lists the documents that aircraft engaged in international navigation must carry, such as the certificate of registration, certificate of airworthiness, appropriate licences and the journey log book. Article 21 concerns reporting of registrations, Article 26 concerns investigation of accidents and Article 35 concerns cargo restrictions.

Question 34International law: ICAO Convention, Chicago Convention, annexes and international organisations

Under the Chicago Convention, what is the status of the Annexes adopted by the Council?

  1. They are Standards and Recommended Practices adopted under Articles 37 and 54 and become effective unless a majority of States disapprove. Correct answer.
  2. They are binding treaties requiring separate ratification by each State before entry into force.
  3. They are advisory guidance only, with no obligation on contracting States.
  4. They are recommendations of the Assembly that take effect only after a unanimous vote.

Explanation

Articles 37 and 54 empower the Council to adopt and amend the Annexes as Standards and Recommended Practices, and they become effective unless a majority of contracting States register disapproval within the specified period. They are therefore adopted through the Convention itself rather than by separate ratification. They are not merely advisory.

Question 35International law: ICAO Convention, Chicago Convention, annexes and international organisations

A contracting State refuses to permit an aircraft registered in another contracting State to enter its territory because the aircraft's certificate of airworthiness does not meet the minimum Standards of Annex 8. Which provision supports that refusal?

  1. Article 5, which grants the privilege of non-scheduled flight
  2. Article 13, which concerns entry and clearance regulations
  3. Article 33, which requires recognition of certificates only if they equal or exceed the minimum Standards Correct answer.
  4. Article 16, which concerns search of aircraft

Explanation

Article 33 obliges States to recognise certificates of airworthiness and licences issued by the State of Registry only where the issuing State's requirements equal or exceed the minimum Standards established under the Convention. Where the certificate falls below those Standards, the State may refuse recognition. Article 5 concerns non-scheduled flight privileges, not certificate recognition.

Question 36International law: ICAO Convention, Chicago Convention, annexes and international organisations

Which ICAO Annex contains the Standards and Recommended Practices for meteorological service for international air navigation?

  1. Annex 15
  2. Annex 3 Correct answer.
  3. Annex 12
  4. Annex 10

Explanation

Annex 3, Meteorological Service for International Air Navigation, sets out the meteorological requirements and the provision of forecasts, observations and warnings for international air navigation. Annex 10 covers aeronautical telecommunications, Annex 12 covers search and rescue and Annex 15 covers aeronautical information services.

Question 37International law: ICAO Convention, Chicago Convention, annexes and international organisations

Under the Chicago Convention, when an aircraft registered in one contracting State is involved in an accident in another contracting State, which State is responsible for instituting the investigation?

  1. The State of Registry of the aircraft
  2. The State of Manufacture of the aircraft
  3. The State of the operator
  4. The State in whose territory the accident occurred Correct answer.

Explanation

Article 26 requires the State in whose territory the accident occurs to institute an inquiry into the circumstances, in accordance with the procedure of ICAO, where practicable. The State of Registry is entitled to appoint observers to be present at the inquiry. The State of Manufacture and the State of the operator may participate but do not hold the primary responsibility.

Question 38International law: ICAO Convention, Chicago Convention, annexes and international organisations

Which international instrument, adopted in 1963, addresses offences and certain other acts committed on board aircraft and is the basis for the Tokyo Convention?

  1. The Convention for the Suppression of Unlawful Acts against the Safety of Civil Aviation
  2. The Convention for the Suppression of Unlawful Seizure of Aircraft
  3. The Convention on Offences and Certain Other Acts Committed on Board Aircraft Correct answer.
  4. The Convention on the Marking of Plastic Explosives for the Purpose of Detection

Explanation

The Convention on Offences and Certain Other Acts Committed on Board Aircraft, adopted at Tokyo in 1963, deals with jurisdiction over offences committed on board and with the powers of the aircraft commander. The Hague Convention of 1970 concerns unlawful seizure, the Montreal Convention of 1971 concerns unlawful acts against safety, and the 1991 Montreal Convention concerns plastic explosives.

Question 39International law: ICAO Convention, Chicago Convention, annexes and international organisations

Which ICAO Annex contains the Standards and Recommended Practices for aircraft nationality and registration marks?

  1. Annex 13
  2. Annex 8
  3. Annex 7 Correct answer.
  4. Annex 5

Explanation

Annex 7, Aircraft Nationality and Registration Marks, specifies the nationality and registration marks to be carried by aircraft and the manner of displaying them. Annex 8 covers airworthiness of aircraft, Annex 5 covers units of measurement and Annex 13 covers aircraft accident and incident investigation.

Question 40International law: ICAO Convention, Chicago Convention, annexes and international organisations

A State wishes to designate a prohibited area over a military installation and to restrict flight over it. Which Article of the Chicago Convention expressly permits a State to restrict or prohibit flying over areas of its territory for military or public safety reasons?

  1. Article 15
  2. Article 12
  3. Article 9 Correct answer.
  4. Article 11

Explanation

Article 9 permits a contracting State, for reasons of military necessity or public safety, to restrict or prohibit uniformly the aircraft of other States from flying over certain areas of its territory, subject to the conditions set out in that Article. Article 11 concerns applicability of laws on entry and departure, Article 12 concerns rules of the air and Article 15 concerns airport charges.

Question 41Aircraft nationality, registration, airworthiness and documents

Under the Convention on International Civil Aviation (Chicago Convention), which State is responsible for registering an aircraft and thereby granting it a nationality?

  1. The State of manufacture of the aircraft
  2. The State in which the aircraft is registered Correct answer.
  3. The State whose airspace the aircraft most frequently uses
  4. The State of the operator's principal place of business

Explanation

The Chicago Convention provides that aircraft have the nationality of the State in which they are registered. Registration is the legal act that confers nationality, and an aircraft cannot be validly registered in more than one State. The place of manufacture, the operator's base or route patterns do not confer nationality.

Question 42Aircraft nationality, registration, airworthiness and documents

An aircraft is registered in two States at the same time. According to the Chicago Convention, what is the consequence?

  1. The registration remains valid if the two States are parties to a bilateral agreement
  2. The registration is valid but the aircraft may only fly in one of the two States
  3. The aircraft may be operated internationally provided both States consent in writing
  4. The registration in both States is invalid, and the aircraft loses any valid nationality Correct answer.

Explanation

The Convention states that an aircraft cannot be validly registered in more than one State. Dual registration is therefore not permitted, and the effect is that the registration in both States is invalid. Bilateral arrangements or consent cannot cure the fundamental prohibition.

Question 43Aircraft nationality, registration, airworthiness and documents

Which document principally establishes that an aircraft complies with the applicable airworthiness requirements and is therefore fit for flight?

  1. The aircraft radio station licence
  2. The certificate of airworthiness Correct answer.
  3. The certificate of registration
  4. The certificate of insurance

Explanation

The certificate of airworthiness is issued by the State of Registry after the aircraft is shown to meet the applicable airworthiness requirements. It is the document that attests fitness for flight from an airworthiness standpoint. Registration merely records nationality, while the radio licence and insurance cover different matters.

Question 44Aircraft nationality, registration, airworthiness and documents

A commercial air transport operator's aircraft has its certificate of airworthiness expire while the aircraft is abroad. Which statement best reflects the standard position under Annex 8 to the Chicago Convention?

  1. The aircraft automatically obtains a new certificate from the State of landing
  2. The aircraft may continue commercial flights indefinitely if the operator self-certifies airworthiness
  3. The aircraft must be dismantled and shipped back to the State of Registry
  4. The aircraft may be flown only for the purpose of proceeding to a place where it can be inspected and a new certificate issued, subject to the State of Registry's conditions Correct answer.

Explanation

Annex 8 recognises that a certificate of airworthiness may lapse while the aircraft is outside the State of Registry. In that case the State of Registry may permit flight to a place where inspection and re-issue can occur, subject to any conditions it imposes. The aircraft cannot continue normal commercial operations on an expired certificate.

Question 45Aircraft nationality, registration, airworthiness and documents

Which document must be carried on board and contains the names of the crew and the points of departure and arrival of the flight?

  1. The aircraft technical log
  2. The general declaration
  3. The journey log book Correct answer.
  4. The operations manual

Explanation

The journey log book records the aircraft's flights, including the names of crew members and the points of departure and arrival. It is one of the documents Annex 6 requires to be carried on board. The general declaration is a customs document, the technical log records defects and maintenance, and the operations manual gives operating procedures.

Question 46Aircraft nationality, registration, airworthiness and documents

Which of the following is a document that Annex 6 requires to be carried on board every international commercial flight?

  1. The certificate of registration Correct answer.
  2. The manufacturer's type certificate
  3. The aircraft maintenance programme
  4. The operator's quality manual

Explanation

Annex 6 lists documents that must be carried on board, and the certificate of registration is among them, together with the certificate of airworthiness, licences of crew members and the journey log book. The maintenance programme, quality manual and type certificate are held by the operator or authority rather than carried on the flight.

Question 47Aircraft nationality, registration, airworthiness and documents

In relation to aircraft nationality marks, which statement correctly reflects the Chicago Convention?

  1. The nationality mark may be chosen freely by the operator to reflect its brand
  2. The nationality mark must be the full name of the State of Registry
  3. The nationality mark is selected from the distinctive marks allocated to the State of Registry and must be displayed on the aircraft Correct answer.
  4. The nationality mark must be the same as the aircraft's registration mark

Explanation

Each State selects its nationality mark from the distinctive marks allocated to it, and aircraft must carry the appropriate nationality and registration marks. The marks must be displayed in the prescribed manner. Operators cannot choose marks for branding, and the nationality mark is distinct from the registration mark.

Question 48Aircraft nationality, registration, airworthiness and documents

For an aircraft used in international air navigation, who or what determines the form and manner of displaying the registration mark?

  1. The State of Registry, in accordance with Annex 7 provisions Correct answer.
  2. The aircraft manufacturer's design standard
  3. The operator's maintenance organisation
  4. The State in which the aircraft is most often operated

Explanation

Annex 7 to the Chicago Convention sets out the requirements for nationality and registration marks, and the State of Registry ensures they are displayed in the prescribed form and manner. Manufacturer standards and operator preferences are not the legal source. The State of operation does not determine the marks of a foreign-registered aircraft.

Question 49Aircraft nationality, registration, airworthiness and documents

An operator wishes to dry-lease an aircraft registered in State A to a company established in State B. What is the standard legal position under the Chicago Convention and Annex 8?

  1. The transfer of registration to State B is always mandatory for any dry lease
  2. The aircraft may be registered in both State A and State B for the lease period
  3. The aircraft automatically loses its nationality when the lease begins
  4. The aircraft may remain on the register of State A, and State A remains responsible for airworthiness, subject to any applicable arrangements Correct answer.

Explanation

The Convention permits an aircraft to remain registered in the State of Registry while operated under a lease, and that State retains responsibility for airworthiness. Article 83 bis allows certain functions to be transferred to the State of the operator by agreement, but registration does not automatically change. Dual registration remains prohibited.

Question 50Aircraft nationality, registration, airworthiness and documents

Which certificate confirms that an aircraft meets the environmental noise requirements applicable to it?

  1. The noise certificate, where required by the State of Registry Correct answer.
  2. The certificate of registration
  3. The certificate of airworthiness only
  4. The radio station licence

Explanation

Annex 16 sets out environmental standards, and many States issue a noise certificate confirming compliance with the applicable noise requirements. This is separate from the certificate of airworthiness, although noise compliance may also be reflected in airworthiness documentation. Registration and radio licensing address unrelated matters.
