ADS-B Out Failure Annunciations Required for Part 23 and 25 Aircraft

By: Stacy Honda, Marketing Manager

The FAA has announced that Automatic Dependent Surveillance-Broadcast (ADS–B) Out failure annunciations in the flight deck are required for Part 23 and Part 25 aircraft.

The latest Universal Avionics Flight Management System (FMS) Software, Version SCN 1001.2/1101.2/1101.2M, includes messaging to alert crews of a failure of the ADS-B Out or transponder system. With this functionality built into the SCN, the upgrade relieves the need to install an additional failure annunciator in the instrument panel.

The new FMS software includes support for two new discrete inputs. These inputs are monitored for data indicating the state of ADS-B Out and transponder failure. In addition, it includes a monitor with messaging capability to alert the crew to a failure of the ADS-B Out or transponder system.

For operators seeking a streamlined ADS-B fail annunciator, SCN 1001.2/1101.2 provides significant savings versus standalone cockpit panel annunciators and Digital Discrete Adapters (DDA). Plus, the SBAS-FMS provides a growth path to Localizer Performance with Vertical Guidance (LPV), Required Navigation Performance (RNP), and with the UniLink® UL-800/801 Communications Management Unit (CMU), Controller-Pilot Data Link Communications (CPDLC) and CPDLC-Departure Clearance (DCL), Future Air Navigation System (FANS), and the European Data Link Mandate.
