RNAV2
RNAV2 is a navigation specification within the ICAO framework for area navigation (RNAV). It defines a lateral navigation performance standard that allows an aircraft to follow routes with a typical allowable lateral deviation of about 2 nautical miles from the intended path for a specified percentage of flight time. In practice, RNAV2 enables navigation along defined trajectories without sole reliance on ground-based navaids, supporting more flexible routing and improved airspace efficiency.
Applications and scope vary by region, but RNAV2 is commonly used for en-route segments and certain terminal
