Proposed Alteration of the Los Angeles, CA, Class B Airspace; Proposed Rule DEPARTMENT OF TRANSPORTATION

摘要

This notice proposes to alter the Los Angeles, CA, Class B airspace area. This proposal would lower the ceiling of the Los Angeles Class B airspace area from 12,500 feet mean sea level (MSL) to 10,000 feet MSL; raise the base altitude west of Santa Monica, CA, from 4,000 feet MSL to 7,000 feet MSL to provide for more airspace for uncontrolled traffic to navigate outside of the Los Angeles Class B airspace area; and expand the eastern, southern and southeastern boundaries for additional airspace for the arrival of high performance aircraft. This action would improve aviation traffic flow and enhance safety in the Los Angeles area while accommodating the concerns of airspace users.
