b. ADS-B Certification and Performance
Requirements.

ADS-B equipment may be certified as a surveillance
source for air traffic separation services using
ADS-B Out. ADS-B equipment may also be
certified for use with ADS-B In advisory services
that enable appropriately equipped aircraft to
display traffic and flight information. Refer to the
aircraft's flight manual supplement or Pilot
Operating Handbook for the capabilities of a specific
aircraft installation.

c. ADS-B Capabilities and Procedures.
1. ADS-B enables improved surveillance ser-
vices, both air-to-air and air-to-ground, especially
in areas where radar is ineffective due to terrain or
where it is impractical or cost prohibitive. Initial NAS
applications of air-to-air ADS-B are for "advisory"
use only, enhancing a pilot's visual acquisition of
other nearby equipped aircraft either when airborne
or on the airport surface. Additionally, ADS-B will
enable ATC and fleet operators to monitor aircraft
throughout the available ground station coverage
area.
