and zoom to different locations and activate various
map capabilities, including:
3-D depictions of ADS-B airspace, airports and
temporary flight restrictions in real time.
Overlays of where ADS-B surveillance
coverage is provided at altitudes of 500; 1,500;
3,000; 5,000 and 10,000 feet AGL .
Non-radar airspace where aircraft transmitting
ADS-B can be seen by ATC .
The research page also includes a list of all FAAcertified equipment. Each type of ADS-B unit must be
paired with a specific position source, such as a Wide
Area Augmentation System, approved by the FAA for
your make and model aircraft . Aircraft owners can
avoid problems by being certain the specific position
source being installed is approved to be paired with
the ADS-B Out unit being installed .
What can ADS-B do for me?
This is the key question most pilots want to answer as
they decide whether they need to equip . With the ADS-B
ground network operational across the country, pilots
in equipped aircraft have access to air traffic services
that provide a new level of safety, better situational
awareness and more efficient search and rescue.
ADS-B transmissions include position, altitude,
velocity, aircraft number and other information .
ADS-B coverage is more extensive than radar,
especially at lower altitudes where general aviation
aircraft often fly; it is also much more precise. ADS-B
uses GPS, which fixes position much more accurately
than radar . It also provides faster position update
rates of about once per second compared to about
once every 12 seconds for radar . It takes a while for
a rotating radar antenna to circle back to the point
where it first spotted an aircraft target to make the next
observation . ADS-B coverage also is often better than
radar coverage in the mountains .
If you want to know the details of how ADS-B Out
and In will work for you in your aircraft, and how they
interact with the ground infrastructure created by the
FAA, visit www.faa.gov/go/equipadsb .
New ADS-B compliant equipment search tool
The Equip ADS-B website also has a new ADS-B
equipment search tool that lets you enter your aircraft
information to search for ADS-B equipment either as
separate components or part of a complete installation
The Installation section of the website is designed
to help general aviation aircraft owners and the repair
shops . It provides information on the hardware you
