Airspace from 18,000 ft Mean Sea Level (MSL) up to and including Flight Level (FL) 600, including that airspace overlying the waters within 12 nautical miles of the coast of the 48 contiguous states and Alaska, and designated international airspace beyond 12 nautical miles of the coast of the 48 contiguous states and Alaska within areas of domestic radio navigational signal or ATC radar coverage, and within which domestic procedures are applied.
