What are ICAO flight procedures that have been agreed upon and organized in annexes to the convention called?

The term used to refer to the ICAO flight procedures that have been agreed upon and organized in annexes to the Convention is known as SARPS, which stands for Standards and Recommended Practices. These guidelines are essential as they provide a framework for the safe and efficient operation of international civil aviation. SARPS ensure that there is a common understanding and standardization among member states, which aids in the uniformity of aviation regulations and practices globally. This is crucial for ensuring safety and coordination across different countries and their respective airspace.

Other terms like AMCs (Acceptable Means of Compliance) or SOPs (Standard Operating Procedures) relate to specific practices and compliance measures but do not encompass the comprehensive collection of agreed-upon procedures outlined in ICAO's annexes. FIS (Flight Information Service) focuses more on the services provided to pilots and does not address the overarching set of established flight procedures. Thus, SARPS is the correct answer as it directly pertains to the organized procedures recognized by ICAO.
