PAPI & Airfield Photometric Calibration System — mobile (Unika / PAC, distributed by Vardhman Airport Solutions) vs Trailer-Mounted Mobile ATC Tower & Air Traffic Management System (Vardhman Airport Solutions)
Spec comparison for two products on Aviation Souk. Both compete in Runway Lighting & Airfield Electrical.
A paired photometric calibration solution — vehicle-mounted mobile runway/taxiway light measurement and tripod-based PAPI angle calibration — enabling airfield maintenance teams to verify ICAO and FAA photometric compliance on the airfield without the airport closing.
A fully self-contained, trailer-mounted control tower providing deployable 360° all-weather ATC capability for emergency, temporary, or remote aerodrome operations — available with rapid hydraulic elevation and an integrated communication, weather, and power suite.
