External ADS-B Annunciator

When one or more GDL 88 faults are present, the ADS-B annunciator activates one or both of two lights to indicate the presence and type of the highest priority GDL 88 fault present. For example, if both a No Position (priority 2) fault and a Fault (priority 3) are present, the ADS-B annunciator will indicate the presence of a No Position fault.
