Avidyne Helios is a new multifunction SBAS flight management system designed for the rigorous demands of corporate, military and special mission helicopters. It sets a new standard for integration in rotorcraft navigation systems. Avidyne Helios FMS provides full Required Navigation Performance (RNP) and Area Navigation (RNAV) capability, including Localizer Performance with Vertical (LPV), Lateral Navigation/Vertical Navigation (LNAV/VNAV), LNAV-Only, and Approach Procedures with Vertical (APV) approach modes.
The Avidyne Helios is a dzus-mount flight management system that meets TSO-C146c for full SBAS/LPV approach guidance, and is an approved GPS position source for ADS-B. Avidyne Helios features easy-to-use flight planning, one-touch departure, airway, and arrival navigation, and Avidyne’s patented GeoFill™ waypoint nomination. Avidyne Helios features a full QWERTY-style dedicated keyboard along with touch-screen hybrid touch user interface that provides easy map panning and flight plan editing. Its extensive I/O is designed to integrate with existing equipment in the aircraft including a long list of EFIS, PFDs, CDIs, HSIs, remote sensors, and autopilots, and it is also an approved ADS-B GPS position source with numerous transponders. Avidyne’s GPS Legacy Avionics Support (GLAS™) provides a direct interface to legacy Collins Proline 21 and Honeywell Primus EFIS systems for vertical guidance during approach operations. This unique integration capability enables EFISs certified before the availability of LPV approaches to have coupled approach guidance on these and other SBAS approaches.
