AMC1 ACNS.D.ADSB.090(b) Flight Deck Interface

ED Decision 2013/031/R

ADS-B   device or function failures, should be indicated in amber or in accordance with the flight deck annunciation philosophy, without undue delay, i.e. a response time within the order of one second.

ADS-B device or function failures may be indicated independently of each other; however, detailed operating instructions should be developed to describe the means to interpret indications.

The ADS-B device or function failure indication should not be confused with an ACAS or Mode S system failure annunciations.

In case of an ADS-B function failure, it is expected that the transponder should continue to support the ACAS, Mode A/C and Mode S functions.

The proper indications of the ADS-B Out system failures should be tested.
