Universal WAAS-FMS Certified on Falcon 20

Alternative Aviation Services has certified a single Universal Avionics Systems' WAAS (wide area augmentation system)-capable FMS (flight management system) on a Falcon 20, enabling it to fly SBAS (space-based augmentation system) approaches.

The Universal UNS-1Fww WAAS-FMS upgrade on the business jet allows GPS to be used as the primary means of navigation from takeoff through Category I precision approaches.  These approaches, which are denoted RNAV (area navigation) (GPS) on approach plates, can use WAAS vertical guidance in lieu of barometric altitude for LNAV (lateral navigation) and LNAV/VNAV (vertical navigation) approach minima.

Universal says its new line of WAAS-capable FMS systems are supplemental-type certificated for Part 23 and Part 25 aircraft and meets FAA TSO-C146b Gamma-3 and DO229D certification criteria. They have been certified on multiple aircraft types, including the King Air, Challenger, B-737 and Astra.  04-06-2008.
