Pilot's Guide to Avionics 2016-2017 - 55
The FAA Equip ADS-B website at www.faa.gov/go/
equipadsb is designed to help inform general aviation
pilots in various stages of decision making about if,
when, why and how to equip with ADS-B - while also
answering the questions that most often arise .
Handy research tools you can use
The first question to research is: "Do I need
ADS-B?" The FAA final rule issued in 2010 designates
the types of airspace where ADS-B will be mandatory
in 2020 .
ADS-B Out will be required in the following airspace:
Class A, B and C airspace .
Class E airspace - areas at or above 10,000
feet mean sea level over the contiguous U .S .,
excluding airspace at and below 2,500 feet
above ground level .
Airspace within 30 nautical miles at certain
busy airports, from the surface up to 10,000
feet MSL .
Above the ceiling and within the lateral
boundaries of a Class B or C airspace area up
to 10,000 feet .
Class E airspace over the Gulf of Mexico at and
above 3,000 feet MSL within 12 nautical miles
of the U .S . coastline .
If you are flying an aircraft that doesn't have an
electrical system such as a balloon or a glider, the
answer is "no" you don't need ADS-B .
But if you are flying an aircraft with an electrical
system, and you want to fly at or above 10,000 feet,
you will need to equip with either a Universal Access
Transceiver or a transponder with extended squitter
capability broadcasting on 1090 megahertz . At Flight
Level 180 and above, aircraft have to be equipped with
1090 MHz, so UAT is not an option .
A decision tree on the Equip ADS-B website will
help aircraft owners determine if they need to equip .
But simply put: ADS-B will be required to fly in most
controlled airspace when the 2020 mandate takes
For those aircraft owners who plan to operate below
10,000 feet, the equipage question hinges on where
they plan to fly. Most controlled airspace will require
the use of ADS-B while uncontrolled airspace will not .
Aircraft owners can download the FAA's ADS-B
Google Earth Airspace Map to view the location of
ADS-B airspace near their home airports, near airports
they want to visit and in airspace along the routes
between these airports . Visitors to the website can pan
