UNSPSC 39111625: Precision approach path indicator (PAPI) system

A precision approach path indicator (PAPI) is a visual aid that provides guidance information to help a pilot acquire and maintain the correct approach (in the vertical plane) to an airport or an aerodrome. It is generally located on the left-hand side of the runway approximately 300 meters beyond the landing threshold of the runway.

UNSPSC 39111625 Precision approach path indicator (PAPI) system is a Commodity code representing specialized airfield lighting systems and testing services that state and local airports procure to maintain and certify navigational lighting infrastructure. Recent solicitations show airports purchasing comprehensive photometric testing of runway and taxiway lighting, including centerline, edge, and touchdown zone lights, with compliance to FAA Advisory Circular 150/5345-46E and automated intensity calculations using mobile test systems with GPS positioning and calibration certification deliverables. The code sees activity from airport authorities and port authorities, primarily those operating commercial service airports managing multiple runway systems requiring periodic photometric validation and constant current regulator testing at multiple intensity levels. Equipment and services are internally staffed or outsourced to specialized photometric testing firms capable of delivering results in standardized Excel and Word formats with documented calibration records.

Lee County Port Authority at Southwest Florida International Airport has issued two recent solicitations under this code. The first, RFQ 2026115BW (due October 29, 2026), requests comprehensive airfield photometric testing of runway and taxiway lighting systems, with a three-year initial contract term beginning September 9, 2026, and compensation detailed in a Service Provider Agreement exhibit. A second, nearly identical RFQ 2026061BW (posted August 20, 2026, due August 20, 2026), sought the same scope with matching contract structure and insurance requirements ($5 million commercial general liability for airside operations; $5 million automobile liability). Both solicitations require providers to furnish all specialized photometric testing equipment, software, and vehicles; the Authority provides only parking. Activity in this code is concentrated in Florida and appears tied to commercial airport capital improvement and compliance maintenance cycles, with response windows typically 30 to 40 days from posting.
