If an airline from a non-JAA country flies to an airport located in a JAA member state, what aviation law applies?

The correct choice is based on the significance of the International Civil Aviation Organization (ICAO) regulations in establishing a framework for global aviation safety, air navigation, and operational standards. ICAO, as a specialized agency of the United Nations, sets international standards and recommended practices that all member states, including both JAA (Joint Aviation Authorities) member states and non-JAA countries, are encouraged to follow. This ensures a harmonized approach to aviation safety and regulation worldwide.

In this scenario, although the JAA regulations may be applied to airlines within member states, they do not extend the same jurisdiction over airlines from non-JAA countries. The NAA (National Aviation Authority) regulations of the destination country could be applicable when considering the operational capabilities and legal entry of the airline operating into that country; however, the base standards of operation and safety align with what is outlined by ICAO.

Therefore, the framework established by ICAO ultimately governs the operations of international flights, making it the primary authority even when a non-JAA airline operates into a JAA member state.
