17 -- TRANSPONDER LANDING SYSTEM (TLS) SOL TLS DUE 021299 POC Vickie L. Gordon, Contracting Officer, (202) 493-4759 WEB: No RFP is available, http://www.asu.faa.gov. E-MAIL: None available, No E-Mail responses!. 17 -- The Federal Aviation Administration (FAA) proposes to purchase or lease Transponder Landing Systems (TLS) from Advanced Navigation & Positioning Corporation (ANCP), Hood River, Oregon. The TLS is a ground-based system approved to support special category I precision approach operations by aircraft equipped with standard Instrument Landing System (ILS) receivers and Mode A secondary surveillance radar transponder equipment. It uses radar beacon transponder replies to establish aircraft position and ILS spectrum transmitters to provide the guidance along the precision approach path to the aircraft's ILS receivers. Only those systems for which type approval has been issued by the FAA, in accordance with 14 CFR 171.75(a) will be considered. ANPC is considered to be the only contractor which possesses the unique expertise to produce these TLSs consistent with the time critical nature of this project. Posted 01/25/99 (W-SN290926). (0025)
