Annex 6: Operation of Aircraft

Scope and Structure of Annex 6: Operation of Aircraft

Annex 6 is a core part of the Chicago Convention framework, focusing on the safe and standardized operation of aircraft worldwide. It is divided into parts that address different types of operations—commercial air transport, general aviation, and helicopter operations. Each part sets out requirements for operator certification, crew qualifications, aircraft equipment, and ongoing oversight.

Key Content Areas

• Operator Certification: Annex 6 requires operators to hold valid certificates, specifying the conditions for issuance, continuation, and revocation. This ensures only competent operators conduct flights.
• Flight Operations Requirements: The annex prescribes rules for flight preparation, in-flight procedures, crew composition, and operational control. These cover everything from flight planning to fuel requirements and emergency procedures.
• Safety and Oversight: Operators must demonstrate ongoing compliance with safety standards. Authorities are empowered to inspect, restrict, or prohibit operations that do not meet requirements.
• Special Approvals: Certain high-risk or complex operations (e.g., low visibility, transport of dangerous goods, extended range flights) require additional specific approvals, as detailed in associated annexes and regulations.
• Application in Europe: Regulation (EU) 965/2012 implements Annex 6 standards in the EU, covering both commercial and non-commercial operations, with specific annexes for each (e.g., Annex V for special approvals, Annex VI for commercial, Annex VII for non-commercial).

Exclusions and Special Considerations

Annex 6 does not apply to all aircraft types—airships, balloons (with some exceptions), and sailplanes are generally excluded. For aviation security, special attention is given to flight crew compartment doors, ensuring protection against unlawful interference.

Definitions and Regulatory Links

Key definitions in Annex 6 and related regulations clarify terms like 'operator,' 'commercial operation,' and 'complex motor-powered aircraft.' These definitions are crucial for understanding which rules apply in different operational contexts.
