The national aviation security programme should apply to which operations?

• A. Only international flights are covered
• B. Only domestic flights are covered
• C. All international civil air transport including cargo and domestic flights at the discretion of each member state
• D. Cargo flights only

Answer: (C)

Focus on the scope of a national aviation security programme. This programme is meant to safeguard all aspects of international civil aviation, including both passenger and cargo operations. Because cargo flights are a key part of international transport and can present security risks just like passenger services, they must be covered. Domestic flights are within a state's sovereignty, so whether they are included is up to that state’s policy, but the baseline obligation is to address international civil air transport comprehensively.

So the best conclusion is that the programme applies to all international civil air transport, including cargo, with the option for domestic flights to be included at the discretion of each member state. The other options are too narrow, excluding either international scope, cargo, or domestic operations.
