Modification to the Gulf of Mexico High Offshore Airspace Area

This action amends the Gulf of Mexico High Offshore Airspace Area. Specifically, this action modifies the Gulf of Mexico High Offshore Airspace Area by extending the boundaries further east and south of the current location to the Houston Air Route Traffic Control Center (ARTCC) Flight Information Region/Control Area (FIR/CTA). The FAA is taking this action to increase the vertical limits of the airspace area from Flight Level (FL) 280 up to and including FL 600. This action provides additional airspace in which domestic air traffic control (ATC) procedures may be used to separate and manage aircraft operations, and will enhance the efficient utilization of that airspace.
