Tucson, Arizona – April 7, 2008 – Universal Avionics Systems Corporation is pleased to announce another successful certification for its WAAS-FMS Flight Management Systems (FMS). The upgrade installation and certification of a single UNS-1Fw WAAS-FMS in a Falcon-20 aircraft was recently completed by Alternative Aviation Services, Inc.

Alternative’s success in certifying Universal’s Wide Area Augmented System (WAAS) FMS enables its operators to fly WAAS approach types. These approaches, which are the fastest growing GPS approach type in the country, require highly precise GPS-derived position information obtained from a Space-Based Augmentation System (SBAS). The Universal WAAS-FMS utilizes an internal GPS receiver to obtain GPS altitude data from the WAAS SBAS and allows GPS to be used as the primary means of navigation from takeoff through Category I precision approach. These approaches, denoted RNAV (GPS) on the approach plate, are approved for WAAS vertical guidance in lieu of Baro altitude for LNAV/VNAV and LNAV approach minima.

Universal Avionics’ new line of WAAS-capable FMS systems are STC’d for Part 23 and Part 25 aircraft and meets FAA TSO-C146b Gamma-3 and DO229D certification criteria. The WAAS-FMSs have been certified for LNAV/VNAV and LNAV on many aircraft types, including Kingair, Challenger, Boeing 737 and Astra.
