Overview

Avidyne Helios™ : Introducing the Next Generation of Flight Management Systems for Helicopters

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.

The Avidyne Helios boasts a variety of features not found in any other FMS system, such as:

Hybrid touch-screen user interface incorporating a full set of buttons and knobs as well as touch screen operation for virtually all functions.
Moving map with extensive airspace, terrain, navaid, and airport display capability

Flight Planning Made Easy

Entering and editing fllight plans has never been easier than with the Avidyne Helios. It features easy-to-use flight planning with easy airway navigation, Avidyne’s exclusive GeoFill™ waypoint nomination, and full autopilot integration. Easy clearance-language flight plan entry, including SIDS and STARS, Procedure Previews, one-touch Holds, and rubberband flight plan editing, reduce workload and heads-down time. Avidyne Helios can store up to 99 flight plans of 128 waypoints each for quick access, and up to 1,000 LAT/LON and Rho/Theta-defined user waypoints. Its cross-fill capability seamlessly automates the process of synchronizing flight plans in dual FMS installations.

Integrated VHF Communication & Navigation

Avidyne Helios provides an optional integrated VHF communication and navigation radio in the same small enclosure. VHF communication capability provides a powerful 16-watt transceiver with frequency nomination and station identification. It also includes the ability to monitor the standby channel at the same time as the active channel.

The integrated VHF navigation system provides VOR navigation, as well as localizer and glideslope approach capability, which is fully integrated and automated with the FMS. It automatically decodes the identification of VORs and localizers, and insures that the proper frequency is tuned as part of the automated approach process.

Monitor stand-by channel while monitoring active channel
Provides VOR navigation, localizer and glideslope approach capabilities
COMM presets with remote channel increment/decrement and XFER

Wireless Connectivity

All Avidyne Helios systems include integrated WiFi and Bluetooth®
connectivity. Numerous tablet application developers support the
Avidyne Helios wireless protocol. Foreflight® and many other apps
are capable of receiving GPS position, ADS-B weather and traffic, XM
Weather, and other data from the Helios system. Integrated wireless
connectivity allows pilots to transfer flight plans from tablet Apps
including ForeFlight. Imagine being able to plan a flight, file a flight
plan, get a clearance, and transfer the flight plan to your FMS,
seamlessly. And all Helios systems have a built-in USB charger
so you can insure your devices have adequate battery levels.

Exclusive Avidyne GLAS™ Functionality

Avidyne 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. The unique integration capability enables EFISs certified before the availability of LPV approaches to have coupled approach guidance on these and other SBAS approaches.
