TIS-B Indication On Ground 

The TIS-B Indication is shown on the 

ground primarily due to the Ground 
Station not receiving your ADS-B Out 
information. 

While the ADS-B In Device is 

receiving traffic information, the data 
package transmitted by the ground 
station does not include your tail 
number and ICAO Code.  

This discrepancy is manifested on the 

IFD as a TIS-B Flag with targets 
present.
