HSI Interface Av-Hsi PMA

The AV-HSI PMA enables essential course and glideslope guidance for ILS (Instrument Landing System) and Localizer Performance with Vertical Guidance (LPV) approaches.

Interfacing with most panel-mounted GPS navigators through three ARINC 429 channels (2 RX, 1 TX), the AV-HSI PMA accessory for the AV-30 communicates course and glideslope guidance for display on the AV-30 during GPS and ILS precision instrument approaches and navigation.
