Pro Star Aviation Announces FAA Certification of Single Universal Avionics UNS-1Fw/-1Lw WAAS FMS for LPV Approach Procedures in the Sikorsky S-76B/C Models

The WAAS/SBAS capable Flight Management Systems (designated UNS-1Fw and UNS-1Lw), when combined with the LP/LPV Monitor, features the ability to fly RNAV (GPS) approaches coded with LPV procedures.

Pro Star Aviation has extensive experience working on avionics for the Sikorsky S-76 helicopter. Over the last 10 years, Pro Star Aviation has worked with numerous Fortune 100 companies that operate S-76 helicopters. Installations have included Honeywell EFIS and Primus 880 Radar, Collins Navigation and Communication suites including Radio Tuning Units, Aircell and TrueNorth Iridium phones, and Sky Connect and Skytrac Iridium based flight following systems. Pro Star Aviation also holds STC’s in the S-76 models for the Garmin GMX-200 MFD and GDL-69 XM Weather system, Universal Avionics System Corp. software upgrade on the Universal Cockpit Display (UCD) system, the L-3 Communications Avionics Systems GH3100 Electronic Standby Instrument System (ESIS), and a Tail Rotor Drive Shaft Cover Antenna Mount. Pro Star Aviation is currently working on the certification effort for the Kollsman GAViS™ Enhanced Vision System (EVS) on an S-76 which is expected to be completed within the next few weeks.

Many of these projects have been accomplished at the customer’s location during annual inspections or heavy maintenance events. Depending on current FMS or GPS equipment installed, the WAAS STC can be installed in a 5-7 day window along with a short verification test flight.
