The Federal Aviation Administration is conducting a market survey under solicitation 693KA8-26-R-11111 to procure Instrument Landing Systems (ILS) for establishing and sustaining Category I, II, and III approach procedure infrastructure. This sources-sought effort, categorized under NAICS 334511, aims to gather industry feedback on a draft performance specification to refine technical requirements and finalize the acquisition strategy for a future contract. The scope encompasses the testing, evaluation, and delivery of critical subsystems, including Localizers, Glide Slopes, Marker Beacons, Remote Control, and Remote Maintenance Monitoring, adhering to FAA Specification FAA-E-2852/b Change 2 and ICAO Annex 10, Volume 1. Interested industry partners must submit their responses by October 2, 2026. Required submissions include a completed comment matrix in Microsoft Word format, a signed Business Declaration Form, and technical data regarding Ultra-Wide Aperture ILS Antenna technology. The FAA is specifically seeking information on localizer arrays with more than 20 elements and glideslope arrays with more than 3 dipoles. Technical requirements emphasize strict adherence to safety and hazard markings per NEMA Z535.1, the prohibition of mercury and asbestos, and compliance with seismic safety and data security standards. All responses must be submitted electronically to the designated points of contact.
