The much anticipated Supplemental Type Certificate (STC) for Universal Avionics WAAS/SBAS Flight Management Systems in the Learjet 60 was recently announced in a joint statement from Universal Avionics Systems Corp. and Haggan Aviation. Haggan Aviation, based out of Englewood, CO, completed the installation of dual UNS-1Fw SBAS/WAAS-FMSs in the Learjet 60 and holds the STC.  

The STC includes approval for 3D coupled WAAS GPS (RNAV) approach types, including Localizer Performance with Vertical Guidance (LPV) procedures. These approaches require the use of GPS signals broadcast from the Wide Area Augmentation System (WAAS), which include signal correction that significantly improve position accuracy and reliability. Operators of aircraft equipped was WAAS-enabled avionics can take advantage of lower descent minima, greater airport options and improved safety in poor weather conditions. In this installation, Universal’s WAAS/SBAS-capable UNS-1Fws replaced earlier generation UNS-1B+ FMSs. 

“Haggan Aviation is pleased to have added this STC to our capabilities,” says Jeff Graser, Vice President of Sales. “We have been working hard over the last several years to establish ourselves as the finest Learjet service facility in the country. This STC is just one more tool to help our customers maintain their aircraft to the latest standards. According to the FAA, there are now more than 1,333 WAAS LPV approaches.  This number now surpasses the number of ILS approaches.” 

 Dan Reida, Universal’s Vice President of Marketing adds, “Bringing new technology to our marketplace requires close teamwork between the installation center and avionics supplier in order to ensure a successful outcome. We have been very impressed with the professionalism and dedication Haggan demonstrated throughout this installation. We believe this will prove a very successful platform for them, as it makes WAAS capability available to the 300-plus aircraft in the Lear 60 fleet.”
