NOTE

−

 

Enhanced surveillance capability is the ability of the aircraft to down-link aircraft derived data via a Mode S transponder. 

Followed by one or more of the following codes if the aircraft has ADS-B capability: 

B1  ADS-B with dedicated 1090 MHz ADS-B “out” capability 

B2  ADS-B with dedicated 1090 MHz ADS-B “out” and “in” capability 

U1  ADS-B “out” capability using UAT 

U2  ADS-B “out” and “in” capability using UAT 

V1  ADS-B “out” capability using VDL Mode 4 

V2  ADS-B “out” and “in” capability using VDL Mode 4 

NOTE

−

 

File no more than one code for each type of capability; for example, file B1 or B2,but not both. 

Followed by one or more of the following codes if the aircraft has ADS-C capability:
