ADS-B FOR FLIGHT SCHOOLS

efforts in the event of an emergency,
even if the accident aircraft isn't
equipped with ADS-B. The FAA and
the National Transportation Safety
Board can use Traffic Information
Service - Broadcast data of equipped
aircraft in the accident area to narrow
the search area and begin rescue or
recovery operations.
Data of non-accident aircraft also
can be used to reconstruct the scenario
immediately prior to an accident,
which is useful for both search and
rescue/recovery and investigation.
Investigation efforts can be much
more efficient and effective if the
accident aircraft is equipped with
ADS-B compared to an accident

aircraft without ADS-B. For example,
after one university aircraft had a hard
landing resulting in a propeller strike
and runway excursion, the university
pulled the data from the aircraft and
determined the approach was high and
fast, likely the result of the pilot experiencing night illusion. This information was available within minutes of
the incident rather than after a lengthy
investigation. Not only did that save
investigating entities' resources,
but it also allowed the university to
share lessons from the incident with
other students quickly, instead of
after a long investigation over several
months.

on everything from the best traffic
pattern for a particular runway to
procedure development. ERAU also is
working on methods for using ADSB-related data to improve the quality
and value of student debriefs.
5. Proactive community
management
Flight training maneuvers typically
occur in concentrated practice areas
and at altitudes that can result in noise
complaints. Add multiple touchand-goes, takeoffs and landings, and
practice approaches necessary in flight
training, and communities can become
sensitive to noise. ADS-B data can be
used to verify students are operating
at appropriate altitudes and to inform
concerned community members of legal and reasonable operating altitudes.
In order to evaluate and manage
flights near sensitive areas, ERAU
has experimented with "geometric
fences." If an airplane penetrates that
fenced area, an email is sent to operations managers. The university says
this allows them to be proactive in
avoiding noise or altitude complaints
in these sensitive areas and to be
proactive when responding to community concerns. UND has established
similar "fences" but uses flight data
monitoring to manage the areas.
Making the case for ADS-B
- now
Although no one wants to spend
extra money on new equipment,
especially when considering the
costs of equipping a multi-aircraft
flight training fleet, the flight training experts with the most ADS-B
experience agree: The cost of not
equipping - that is, the potential for
a serious accident - is too high to
delay in seeking an ADS-B solution
for your fleet.
The ADS-B Out 2020 mandate is
here to stay, and it's prudent for flight
training organizations to include
