When flying over Malaysia, which law regarding aircraft operations should be followed by a Philippine-registered aircraft's crew?

When operating a Philippine-registered aircraft over Malaysia, the crew must adhere to Malaysian regulations. This is based on the principle of territoriality in aviation law, which stipulates that aircraft operations within a country's airspace are subject to the laws and regulations of that particular country. Malaysian aviation authorities maintain jurisdiction over all aircraft operating in their airspace, regardless of the aircraft's country of registration.

Even though there are international standards set by organizations like the International Civil Aviation Organization (ICAO), each country has the authority to implement its own specific regulations and requirements. Therefore, when flying over Malaysia, it is essential for the crew to comply with Malaysian regulations to ensure safety, legal compliance, and to avoid any potential penalties or enforcement actions by local aviation authorities.

The other options relate to different regulations that would not be applicable in Malaysian airspace; thus, they would not govern operations of an aircraft over that territory. Following the appropriate regulations is crucial for maintaining operational integrity while ensuring compliance with international aviation law.
