FAA Certifies Universal Avionics WAAS-FMS on Bombardier CL-600 Series

The FAA has issued a Part 25 STC (supplemental type certificate) to Universal Avionics Systems for its new FMSs (flight management systems) enabled for WAAS and SBAS (wide area and space-based augmentation systems) on Bombardier CL-600s, CL-601s and CL-601-3Rs.

Universal's new generation WAAS/SBAS-enabled FMSs include the UNS-1Lw, UNS-1Ew, UNS-1Espw, and UNS-1Fw, all of which are now available for business, commercial, and regional aircraft, according to the company.

In addition to being capable of LNAV/VNAV (lateral navigation with vertical guidance) approaches, Universal says its new WAAS-FMS could be used to fly over 700 SBAS WAAS/LPV approaches the FAA has already published with minima as low as 200 feet and ½-mile visibility.

According to the FAA's Navigation Services Website, these precision approaches are now available to properly equipped aircraft because of the new L5 GPS civil signal that became available in 2007 to augment the previous existing L1 signal for necessary integrity data.

Universal's WAAS-FMS uses SBAS to improve the accuracy, availability and integrity of its GPS-derived position, thereby increasing navigation capabilities for all classes of aircraft in all phases of flight.  02-13-2008.
