Tucson, AZ – July 9, 2013 – Universal Avionics' long-time customer, Horizon Air, has once again hit a new milestone. On June 25th, the Federal Aviation Administration (FAA) approved Horizon Air for Required Navigation Performance (RNP) 0.1 Authorization Required (AR) approach operations, supported with dual Universal Avionics UNS-1Ew WAAS/SBAS-Flight Management Systems (FMS). This is certainly a significant achievement as only one other airframe in aviation history has been approved for RNP 0.1 AR by the FAA.

RNP AR approach operations require the highest level of navigation performance and are unlike any approaches familiar to most operators. The benefits, such as improved safety, efficiency and capacity, are a direct result from procedure design flexibility, reduced obstacle clearance areas and curved flight paths.

In addition to lower approach minimums and improved reliability at airports, smaller RNP values allow Horizon Air to fly RNP approaches to more runways. There are several runways in the Northwest U.S. that used to be accessible only by a circling approach maneuver. With RNP 0.1 AR approaches, Horizon Air can now fly a stable 3D flight path to touchdown.

"Universal Avionics is excited to congratulate all of our friends at Horizon Air," said Scott Campbell, Universal Avionics' Director of Airline Military Sales and Marketing. "It is great to be partnered with such a forward-thinking and innovative airline that proudly sets the pace for others to follow," he added.

"Since we began flying RNP 0.3 AR approaches over a year ago, Horizon Air has been collecting Flight Operations Quality Assurance (FOQA) data and now has safety, fuel burn and flight time data for thousands of RNP approaches," said Perry Solmonson, Director of Flight Standards and Training with Horizon Air. "For safety, the biggest news is that we have seen no unstable RNP approaches – that's important to emphasize; zero unstable approaches out of several thousand flown," he added. "Other benefits of fuel burn and flight time with RNP approaches are shown by FOQA to be virtually identical during both visual and instrument weather conditions, while non-RNP instrument approaches show a significant increase in time and fuel to complete the approach and landing."

Certified on over 50 aircraft types, Universal Avionics' WAAS/SBAS-FMS was the first to be approved for Part 25 aircraft. To date, over 2,500 WAAS/SBAS-FMS units have been installed. To learn more about Universal's line of WAAS/SBAS-FMSs, visit
