QUESTIONS: ADS-B

Non-Performing
Equipment
The following information is from the Dec.
20, 2017, Federal Register notice titled "Change to
Automatic Dependent Surveillance-Broadcast Services."

Question:

What happens if my customer has an ADS-B
Out installation that is not broadcasting properly?

Answer:

The FAA has begun a process of "filtering" aircraft
with a known NPE. This filter, in essence, will not
recognize the aircraft as being ADS-B equipped. From
the Federal Register notice:
The FAA is implementing a filter for certain
ADS-B equipped aircraft broadcasting erroneous
or improper information when the broadcast
information could affect the safe provision of air
traffic services. Any aircraft subject to the filter
will not have its ADS-B information sent to an
air traffic control facility nor will the aircraft be
a client for TIS-B services.

Affected aircraft will continue to receive ATC
services within radar coverage using secondary
radar information.
To reduce the potential hazard presented by
NPE aircraft, the FAA is filtering individual
24-bit ICAO address codes (also known as
Mode S codes) for certain aircraft from the
FAA's operational ADS-B network. The FAA is
implementing an ATC filtering capability on Jan.
2, 2018. This filtering prevents processing of data
transmitted by uniquely identified NPE aircraft
within FAA air traffic control systems and by the
FAA TIS-B service.
ATC will continue to receive transponder replies
to secondary radar interrogations and will be able
to provide ATC services within radar coverage to
aircraft subject to the filter, using secondary radar
information.
Also, any aircraft with a filtered ICAO address
code will continue to appear as a ''target'' to
nearby aircraft with ADS-B-In equipment.
