Establishment of Class E Airspace; Metropolitan Oakland International Airport, CA

This action will establish a Class E airspace area consisting of airspace extending upward from the surface designated as an extension to the Class C surface area at Metropolitan Oakland International Airport, CA. The establishment of this E3 airspace is necessary in order to retain the existing instrument approach procedure known as the ILS RWY 27R at Metropolitan Oakland International Airport. Recent installation of new Runway Visual Range (RVR) equipment serving Runway 27R at Oakland has resulted in the need to revise the weather minimums for the ILS RWY 27R instrument approach procedure. In conjunction with revising those minimums, a modification to the protected airspace for the ILS RWY 27R is required in order to satisfy current terrain clearance specifications determined by Federal Aviation Administration Flight Standards Service to be essential for ensuring aviation safety.
