International Civil Aviation Organization (ICAO) Adopt best practices and regulations for international air navigation and transport. The International Civil Aviation Organization (ICAO) creates regulations for aviation safety, security, efficiency and regularity and environmental protection. The organization also regulates operating practices and procedures covering the technical field of aviation.
ICAO requires pilots to be proficient in English. The limitations section of a pilot certificate is the only place where it would make sense to put free-form text. So rather than redesign the certificate fields, they put it in that section. TMetzinger, Aug 2, 2012
