The HS34 is an optional expansion module that extends the HSI function already built into and displayed on Dynonís EFISs. This panel-mounted device not only expands the HSI functionality but also enables several new features for any Dynon EFIS, EMS or FlightDEK instrument to which it is networked.
The expansion module concept provides exceptional value and performance while preserving the affordability of Dynonís existing equipment. This modular approach offers greater flexibility when configuring new aircraft panel systems and facilitates future expansion if so desired. The HS34 is now available in the horizontal and vertical mount configurations.
The front panel provides dedicated controls and indicators that optimize the pilotís control over the HSI. The controls are backlit to facilitate night flight conditions. Separate knobs are used for setting the Heading, the Course (OBS) or entering general purpose Values. Other controls include NAV and Bearing Source buttons that facilitate independent selection over each input. Pilots receive feedback of the currently selected navigation source type from separate GPS and NAV indicator lights.Expanded EFIS/EMS Capabilities
In addition to expanded HSI functionality, the HS34 also provides several powerful features to interconnected Dynon instruments that include:
The HS34 expansion module is network connected to Dynonís line of avionics via the Dynon Smart Avionics Bus (DSAB). This two-wire connection not only simplifies wiring but extends individual module benefits to multiple interconnected Dynon instruments
Per Dynon, while the HS34 was designed to interface with other types of avionics, it should work with the AvMap Efis.
