uAvionix AV-HSI | FAA-PMA Certified

The uAvionix AV-HSI is a modern electronic horizontal situation indicator designed to replace or complement traditional mechanical HSI systems in general aviation aircraft. Featuring a clear digital display in a compact, panel-mount form factor, the AV-HSI delivers accurate heading, course deviation, and navigation information when interfaced with approved GPS or navigation sources.

Designed for seamless integration into modern avionics stacks, the AV-HSI provides pilots with an intuitive presentation of lateral navigation data while reducing mechanical complexity and maintenance associated with legacy gyroscopic instruments.

The unit is optimized for installations where space, weight, and reliability are critical, making it well-suited for both VFR and IFR-equipped aircraft when installed in accordance with approved data.
