The correct answer indicates that a sovereign country or governmental unit must authorize GPS instrument approach operations outside the U.S. This is because aviation regulations and procedures, including those governing navigation systems like GPS, are established by the country in which the operation is taking place.

When flying in international airspace or when operating within a foreign country’s airspace, pilots must adhere to the local regulations and requirements. Each country has its own authority that governs flight operations, including the use of navigational aids and approaches. This may involve either a formal aviation authority or a governmental body that oversees and regulates aviation within that jurisdiction.

In contrast, other options do not accurately reflect the structure of aviation authority and regulations outside the U.S. For example, the FAA Administrator’s authority does not extend beyond U.S. borders, and aircraft flight manuals provide operational guidance but do not confer regulatory authority in foreign airspace. Similarly, while regulatory bodies may exist in various countries, the requirement for specific authorization from a recognized country or governmental unit is paramount for international operations involving GPS approaches.
