Avidyne Corporation’s dzus-mounted Avidyne Helios multifunction flight management system (FMS) for helicopters received a Technical Standard Order (TSO) approval from the Federal Aviation Administration (FAA.)

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 flight planning, one-touch departure, airway, and arrival navigation.

“Avidyne Helios provides huge benefits for many helicopter operators and getting TSO approval is just the next step for Avidyne as we continue our growth into the turbine-class helicopter market,” said Avidyne CEO Dan Schwinn in a statement.

“Avidyne Helios gives our customers a powerful new option when upgrading their GPS/FMS navigation capabilities, especially for single- and twin-turbine-class helicopter operators with older-generation EFIS displays where options have been limited,” added John Talmadge, Avidyne’s Vice President of Worldwide Sales. “This TSO approval allows MRO facilities to begin their own Supplemental Type Certificates (STC) programs and field-approved installations into rotor-wing aircraft.”
