Airports/Locations: Special Operating Restrictions

This action amends the Appendix listing airports/locations with special operating restrictions in FAA's general operating and flight rules. Specifically, this action adds an additional entry for Houston, TX (William P. Hobby Airport), and San Diego, CA (Marine Corps Air Station Miramar), to the Appendix, which lists the airports where aircraft operating within 30 nautical miles (NM) of the listed airports, from the surface upward to 10,000 feet mean sea level (MSL) must be equipped with an altitude encoding transponder. The FAA is taking this action to correctly identify applicable airports under the appropriate sections in the Appendix.
