Which device provides received ADS-B information through the Ballard Bus Box to the Mission Processor, combining with TCAS information for the Minotaur tactical picture?

• A. Garmin GDL-88
• B. Garmin GDL-50
• C. L3Harris ADS-B Gateway
• D. Aviation Data Link Unit

Answer: (A)

ADS-B data needs to be fed into the Mission Processor so it can be merged with TCAS tracks to create the Minotaur tactical picture. The Garmin GDL-88 is an ADS-B data-link receiver that provides received ADS-B information to the Ballard Bus Box, which in turn feeds the Mission Processor. This path enables ADS-B targets to be fused with TCAS information for the unified display.

The GDL-50 is a portable ADS-B receiver intended for use with Garmin handheld or cockpit devices and does not integrate with the Ballard Bus Box and Mission Processor in this configuration. The L3Harris ADS-B Gateway serves as a gateway in other architectures but isn’t the device that delivers ADS-B data through the Ballard Bus Box to the Mission Processor for the Minotaur picture. The Aviation Data Link Unit is a generic term and does not specify the actual integration used here.
