−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.
