Universal WAAS FMS Gains STC

Universal Avionics last month said it received an STC allowing installations of the company’s line of WAAS-capable FMS units in the Bombardier Challenger 600, 601 and 601-3R. Universal’s line of WAAS-ready flight management systems includes the UNS-1Lw, UNS-1Ew, UNS-1Espw and UNS-1Fw. The units support nonprecision and Lnav/Vnav approaches that give users access to the more than 700 WAAS/LPV (lateral precision with vertical guidance) approaches that the FAA has published so far. WAAS/LPV approach criteria provide landing minimums as low as 200 feet and half-mile visibility.
