ICAO Annex 2 (Rules of the Air)

ICAO Annex 2, also known as the Rules of the Air, sets internationally agreed standards for safe and efficient aircraft operations. It outlines basic principles like right-of-way rules, aircraft separations, and communication procedures to prevent collisions and confusion in the sky. These rules ensure pilots and air traffic controllers worldwide follow consistent practices, fostering safety, predictability, and coordination during all phases of flight—whether flying solo or in traffic. Compliance with Annex 2 helps maintain order in busy airspace, supporting international aviation safety standards.
