ADS-B 
Automatic Dependent Surveillance Broadcast. Automatic 
Dependent Surveillance–Broadcast (ADS–B) equipment 
is an advanced surveillance technology that combines an 
aircraft’s positioning source, aircraft avionics, and a ground 
infrastructure to create an accurate surveillance interface 
between aircraft and ATC. 
ADS-B  In 
ADS–B In refers to an appropriately equipped aircraft’s ability to 
receive and display another aircraft’s  ADS–B Out information 
as well as the ADS–B In services provided by ground systems, 
including Automatic Dependent Surveillance–Rebroadcast 
(ADS–R), Traffic Information Service–Broadcast (TIS–B), and, 
if so equipped, Flight Information Service–Broadcast (FIS–B).
ADS-B Out 
ADS–B Out provides air traffic controllers and other aircraft 
with real-time position information that is, in most cases, 
more accurate than the information available with current 
radar-based systems. With more accurate information, ATC 
will be able to position and separate aircraft with improved 
precision and timing. 
ADS-R 
ADS Rebroadcast. ADS–R collects traffic information from 
each broadcast link and rebroadcasts it to ADS–B In equipped 
operators on the other broadcast link. 
AIRB 
Airborne Situational Awareness. An ADS-B In application that 
provides the ADS-B and external traffic system targets on a 
display to be used by the flight crew for situational awareness. 
Anonymous Mode 
The Anonymous Mode, when armed, will replace the Flight ID 
with a temporary randomized number for privacy while the 
position information will still be provided. 
CSA 
Conflict Situational Awareness. A traffic alerting feature to 
increase flight crew situational awareness of traffic situations 
that could lead to a hazardous condition in the near term. 
Extended Squitter 
With Extended Squitter capabilities, position, velocity, and 
heading information are automatically transmitted by the 
1090 transponder to other aircraft and ground stations.
