Universal Avionics Introducing New Line of WAAS-Enabled FMS

Universal Avionics Systems Corporation (UASC) is introducing a new product line of WAAS (wide area augmentation system)-enabled flight management systems for business and regional jets.

The new suite of FMS, known as the UNS-1Lw, UNS-1Ew, UNS-1Espw, and UNS-1Fw, are ready to be approved for all normal en-route operations, including oceanic, and approaches that include LNAV/VNAV (lateral navigation with vertical guidance) and LPV (localizer performance with vertical guidance).

According to the company, the receiver on the new FMS has extensive anti-jamming capabilities in the RF (radio frequency) hardware and incorporates all-in-view tracking of up to 12 satellites with a loss-of-lock re-acquisition time of less than three seconds.  It also meets the CWI (continuous wave interference) specification of RTCA DO-208 and DO-229.

Because the new systems meet FAA DO229C and DO178B Level B requirements without requiring add-on sensors, they are ideal for application in both the forward fit and retrofit markets, according to Paul DeHerrera, Universal Avionics' vice president of marketing and product support.

The company expects the FAA to certify the system in this year's 4th-quarter.  03-29-2007.
