Compatible Display Requirements for the GDL 88

In a minimal installation, the GDL® 88 datalink provides the required ADS-B Out functionality with a standalone set of annunciators and control switches installed in the cockpit. When a GDL 88 is installed without interface to an external display, some ADS-B In functionality is still retained. A traffic annunciation light is installed in the cockpit for CSA (Conflict Situational Awareness) alerts and aural alerts are provided for these threat aircraft, to include directionality from the ownship and range.
