Abstract : Test and evaluation of an Advanced Integrated Landing System (AILS) was conducted. The AILS is a microwave, scanning beam system and provides precision azimuth and elevation guidance signals to an aircraft. The system incorporates a distance measuring equipment (DME) function, as well as a radar function for providing precision approach radar (PAR) type monitoring of an approach. During the test program, AILS approaches were made in fixed-wing aircraft, both prop and jet, including short take-off and landing (STOL) aircraft. Based on evaluation of the data collected, it was determined that (1) the AILS is capable of providing air-derived space position information to the following accuracies: DME data to plus or minus 100 feet or 1 percent of distance, whichever is greater, azimuth angle data to plus or minus 0.05 deg 1 sigma, and elevation angle data to plus or minus 0.03 deg 1 sigma; (2) the system is not adversely affected by overflying aircraft, and taxiing aircraft and/or other vehicles only affect performance when stopped so that they effectively shadow a transmitting antenna; (3) some minor system deficiencies exist. Proposed corrective measures are discussed. (Author)
