WAAS FMS with LPV Approach Capability to be Offered on Bombardier Dash 8 Aircraft

Austin, Texas, May 24, 2010 —DAC International announced today that it has successfully completed its Type Certificate Inspection (TIA) and is now awaiting award of the Supplemental Type Certificate (STC) for the installation of dual Universal Avionics Systems Corporation, UNS-1Lw with Wide Area Augmentation System (WAAS) and Localizer Performance with Vertical Guidance (LPV) approach capability on Bombardier Dash 8 series aircraft.

The Federal Aviation Administration is reducing dependence on older conventional land-based navigation aids such as Instrument Landing System (ILS) and is moving towards increased use of Global Positioning System (GPS) navigation. Among the fastest growing of these approach types in the United States are the WAAS and Satellite-Based Augmentation Systems (SBAS).

Operators of aircraft equipped with Universal's WAAS-enabled FMS can take advantage of lower descent minimums, greater airport accessibility and improved situational awareness. The installation includes dual UNS-1Lw with either 5” or 4” Displays and covers Bombardier Dash 8-100/200/300 series aircraft.
