Member states should designate an appropriate authority to maintain a national aviation security programme that applies to which of the following?

• A. Only to passengers and aircrew in international civil transport flights
• B. Only to passengers and aircrew in international civil and domestic flights
• C. To all international air transport including cargo and domestic flights at the discretion of each member state
• D. Only to all international civil transport including aircraft engaged solely in the carriage of cargo

Answer: (C)

The key idea is that a nation must establish an authority to maintain a national aviation security programme that covers the entire spectrum of its air transport operations, not just parts of it. The security programme should apply to all international air transport—including cargo—and also to domestic flights. This breadth ensures there are no gaps where security controls are missing, whether the flight is international or domestic, passenger, crew, or cargo. The option that states the programme applies to all international air transport including cargo and domestic flights, with tailoring allowed by each member state, best reflects this comprehensive scope. Narrow options that limit to passengers only, or exclude domestic operations, would miss significant areas where security measures are needed.
