GPS Instrument Approach Procedures Development and Flight Inspection

Jimmy R. Snow

Abstract:	The Federal Aviation Administration (FAA) has implemented an aggressive program to support the integration of GPS into the National Airspace System through the rapid development and publication of stand- alone GPS instrument approach procedures. This paper outlines the activities that AVN has t‘aken to support this objective in the areas of GPS instrument approach procedures development and flight inspection. An organizational description of AVN is provided with the responsibilities of each major element and the part they play in supporting GPS development and implementation. Specific GPS achievements for 1995 and 1996 are listed as they relate to the number of procedures developed, flight inspected, and published. Flight inspection policy concerning procedures, maneuvers, and criteria is provided for commissioning and periodic inspections. New stand-alone GPS nonprecision procedure design criteria using the “T” design and Terminal Arrival Area concept is discussed with background information concerning their development and objectives. Specific pilot procedures and proposed arrival limitations are explained with their various uses. AVN’s transition to the wide area augmentation system (WAAS) instrument approach procedures development and flight inspection is discussed. The WAAS transition involves development of new precision approach development criteria, flight inspection criteria, and flight inspection aircraft modifications. The WAAS flight inspection procedures and criteria development project with the Ohio University, Avionics Engineering Center, is outlined as it relates to the objectives of the grant and expected outcomes. AVN is directly involved in providing support for the Special Category I (SCAT I) systems and will be responsible for instrument approach procedures design and flight inspection requirements. This paper is an operational look at GPS procedures in the National Airspace System and the support it has taken to make them available to the flying public. It covers current and future GPS instrument approach procedure development projects and flight inspection requirements.
