AUSTIN, Texas, Nov. 21, 2013 – DAC International, a Greenwich AeroGroup company, announced today that the European Aviation Safety Agency (EASA) has approved its supplemental type certificate (STC) for the ATR 42 and 72 aircraft equipped with the Universal Avionics UNS-1Lw FMS to be operated into airports that have so-called LPV (Localizer Performance with Vertical) Approach procedures in place.
LPV approaches are the highest-precision GPS/SBAS (Space Based Augmentation System) WAAS/EGNOS-enabled aviation instrument approach procedures available today that do not require specialized aircrew training requirements.
“From the pilot’s viewpoint, an LPV approach looks and flies like an Instrument Landing System (ILS) procedure, but the SBAS approach is more reliable and can be designed for every runway,” said General Manager for DAC International Francisco Hernandez. “The main difference between ILS and LPV is that LPV is based upon SBAS positioning signals, rather than a ground-based localizer and glideslope transmitter. It can provide vertical guidance as low as 200 feet Above Ground Level (AGL) which is great for the pilot.”
The UNS-1Lw FMS installation on the ATR is compatible with the SBAS systems around the world such as the US Wide Area Augmentation System (WAAS), European Geostationary Overlay Navigation (EGNOS) system, the Japanese Multi-Functional Satellite Augmentation System (MSAS) and the Indian GPS And Geo-Augmented Navigation (GAGAN).
The FMS seamlessly integrates with the aircraft’s Display Systems and Automatic Flight Control and provides guidance from take-off to landing. It is compliant with B-RNAV, P-RNAV and RNAV Approaches including LPV.
As of October 2013, Europe has approximately 76 LPV approaches. The ATR installation also complies with European B-RNAV, P-RNAV and other RNAV Approach Procedures.
United States Federal Aviation Administration STC validation is currently in process on this product.
