uAvionix AV-HSI | FAA-PMA Certified

The AV-HSI enables course and glideslope guidance display on multiple connected AV-30-C to enable GPS and ILS precision instrument approaches and enroute guidance.

The AV-HSI adds three ARINC 429 channels (2 receive, 1 transmit) to interface with most panel-mounted GPS navigators. In addition, the AVHSI includes four serial ports that act as a hub between multiple AV-30C as well as supporting portable GPS and serial VOR/ILS devices.

The hub capability forwards navigation guidance to all connected AV-30-C as well as synchronization of barometric pressure setting, transponder settings, heading bug, OAT, and autopilot modes. If an AV-Link is connected directly to the AV-HSI, this hub function also serves traffic, carbon monoxide alerts, and software updates from the AV-Link to all connected AV-30-C.

The AV-HSI may be connected to one GPS navigation source and one VHF navigation source, whether from one combined GPS nav/com unit or from a standalone GPS navigator and VHF navigator. If the installer wishes to connect to multiple GPS navigators, multiple AV-HSI and independent AV-30-C are required. This creates a fully redundant system.

Can the AV-HSI display glideslope information for ILS or LPV approaches?

Yes, the AV-HSI enables both lateral (course) and vertical (glideslope) guidance to be displayed on the AV-30, supporting precision approaches such as ILS and LPV.

Does the AV-HSI PMA require the AV-Link to function?

No, the AV-HSI PMA does not require the AV-Link for operation. It connects directly to the AV-30 via serial and ARINC 429 interfaces, though AV-Link may still be used in the system for additional functionality such as ADS-B display or software updates.

Is the AV-HSI PMA FAA certified?

Yes, the AV-HSI PMA is a certified part (PMA approved) and can be installed in certified aircraft as part of the AV-30-C system, provided installation requirements are met.

How does the AV-HSI install in my aircraft?

Installation is straightforward for most aircraft and involves wiring the AV-HSI to your GPS navigator and the AV-30 using ARINC 429 and serial connections. A certified avionics technician should perform the installation to ensure compliance with FAA regulations and aircraft compatibility.

Is the AV-HSI PMA compatible with my GPS navigator?

The AV-HSI PMA interfaces with most panel-mounted GPS navigators that support ARINC 429 output, including models from Garmin and other leading manufacturers. It uses two ARINC 429 receive channels and one transmit channel to communicate navigation data to the AV-30.
