Planning for Complementary MLS/GPS Operations

Karen L. Burcham

Abstract:	The Microwave Landing System (MLS) and Global Positioning System (GPS) are FAA naviga- tion and landing systems that will play major roles in the National Airspace System (NAS) of the next century. The FAA is committed to the implemen- tation of MLS for precision approaches, and is pursuing an aggressive program to determine the capabilities of GPS for use during all phases of flight. Much of the research, test and evaluation that has been performed on MLS and GPS has focused on each system independently. Currently, signifi- cant interest and investigation has been focused on the techniques and benefits associated with the complementary operation of these systems. A previous paper established a framework to develop complementary roles for both systems. This paper focuses on how the FAA and aviation industry will develop and implement techniques and infrastructure to support fully integrated MLS and GPS for terminal area operations. The specific purpose of this paper is to discuss the FAA’s plan to determine the feasibility of applying complementary MLS/GPS capabilities to the ranging function necessary for curved/segmented approaches. This one application is particularly attractive for its potential to reduce functional redundancy in the airspace system and provide “seamless” transition from en route to terminal area to precision approach guidance.
