of an FAA ground station with available targets of opportunity. If this is not the case, it is
recommended that these checks be performed in flight within range of an FAA ground station.
If the installed system is configured to receive ADS-B In data through an interface with an ADS-B In
capable unit (GNX 375, GTX 3X5 or GDL 50R/52R), the interface is verified as follows:
1. Verify the GDU is in normal mode.
2. Select the Traffic page on the home screen of the MFD or the multi-function pane on the PFD.
