Tucson, AZ – April 10, 2009 – Two “first of type” Supplemental Type Certificates (STCs) were
issued to West Star Aviation for Universal Avionics WAAS/SBAS-FMS on March 26, 2009. The
STCs are for the UNS-1Lw WAAS/SBAS-FMS with LP/LPV Monitor in the Cessna 550 Bravo
series and Cessna V 560 series aircraft. In what marks the first approval of Universal’s WAAScapable
FMS for these aircraft types, West Star’s achievement opens the door for all other
Cessna 550 and 560 operators to add Wide-Area Augmentation System (WAAS) capabilities to
their aircraft.
With its WAAS/SBAS-FMS product line, Universal Avionics was the first manufacturer to provide
WAAS/SBAS capability for Part 25 Transport Category aircraft, like the Cessna 550 and 560.
West Star’s STCs include approval for 3D coupled WAAS GPS (RNAV) Localizer Performance
with Vertical Guidance (LPV) procedures. These approach types, referred to as RNAV (GPS)
LPV approaches on the approach chart, are the fastest growing GPS approach type in the U.S. In
fact, LPV approaches now outnumber ILS approaches. As part of the NextGen National Airspace
System improvement plan, the FAA is focused on reducing the industry’s dependence on older
ground based navaids such as ILS, and increasing the use of GPS navigation via the Wide Area
Augmentation System (WAAS) Satellite-Based Augmentation System (SBAS). Because of its
ability to alleviate airspace congestion, save fuel and improve safety, SBAS technology is being
applied worldwide, with systems in Europe and Japan to be operational for aircraft use soon.
Operators of aircraft equipped with SBAS-enabled avionics take advantage of lower descent
minima, greater airport accessibility and improved performance and safety in poor weather
conditions. The WAAS/SBAS-FMS allows pilots to fly to ILS-like minimums at airports without an
ILS approach, or in inclement weather. With the WAAS/SBAS-FMS, pilots can fly with RNP-like
accuracy of 0.3 NM and minima as low as 200 ft without special operational approval from the
FAA, as required for RNP SAAAR approaches.
