This report documents the approaches portion of the Fixed Wing Microwave Landing System MLS Terminal Instrument Procedures TERPS data collection and processing project using a Cessna 172 C-172 aircraft. This is one part of the Fixed Wing MLS TERPS data collection and processing program being performed at the Federal Aviation Administration FAA Technical Center. The program was undertaken to collect flight test data in various aircraft to establish a data base for development of MLS TERPS criteria. Data were collected during both missed approaches and landings using glideslopes of 3 deg, 4 deg, and 5 deg with all flights being tracked by ground based tracking systems. Statistical processing was performed on both the airborne and tracker data, and various graphical plots were produced. The processed data were delivered to AVN-120 for inclusion in the MLS TERPS criteria development data base.
