NOTE: The ADS-B receiver is a 1090ES receiver and cannot receive
978 MHz UAT broadcasts.
Air-to-air broadcasts from other aircraft equipped with 1090ES ADS-B Out
are used for traffic correlation. Traffic or weather uplinks from ADS-B ground
stations are not used. ADS-B broadcasts must be correlated with an active
transponder reply in order to be shown on the traffic display. Uncorrelated
ADS-B broadcasts are not used, and ADS-B correlation is not used for Traffic
Advisories.
The ADS-B receiver functionality is optional and requires GPS and magnetic
heading interfaces to perform the correlation function.
