## Abstract

This action amends Class E airspace extending upward from 700 feet Above Ground Level (AGL) at Altoona, PA. The development of a Standard Instrument Approach Procedure (SIAP) based on the Global Positioning System (GPS) at Altoona-Blair County Airport has made this action necessary. This action is intended to provide adequate Class E airspace for instrument flight rules (IFR) operations by aircraft executing the GPS RWY 2 SIAP to Altoona-Blair County Airport.
