ABSTRACT as SESAR in Europe and the myriad


study will be on the use of NextGen Air Traffic Control automation by using a
sample of information on pilot deviation form an unnamed airline.  As ADS-B implementation has been fully
implemented with this airline, I wanted to study how the automation is affecting
(increasing or lowering) deviations. 
Using FOQA data received from aircraft data recorders I was able to get
a sample from 50 aircraft flying out of JFK for ground-based operations before
and after ADS-B implementation. According to the FAA, ADS-B is an environmentally friendly technology
that enhances safety and efficiency, and directly benefits pilots, controllers,
airports, airlines, and the public. It forms the foundation for NextGen by
moving from ground radar and navigational aids to precise tracking using
satellite signals.  Results unfortunately
were not returned by the time of the writing of this paper and I have zero
conclusions to offer.  That being stated
as someone who has flown both with and without ADS-B, I can state that controllers
are much more aware of where aircraft are and are able to stop them much
quicker if something is wrong.

During my first course of my master’s degree I
wrote papers on the implementation of NextGen air traffic control into the Air
Traffic Management System.  This included
U.S. NextGen software, as well as SESAR in Europe and the myriad of other new
systems that are being adopted and meant to work together across the
globe.  These systems are hoped to allow
for greater capacity of air travel in an ever-growing market.  I wanted to use my time and research to see
if the new systems are actually increasing safety as they increase
automation.  I have been working with the
company that I work for in getting data from flight recorders to help with
this.  It has been a process, as most of
the information is confidential, so it must be handled with care.  That being said, no information that is being
given out in this paper is confidential but will not contain names of people or
the company. 
With the completion of ADS-B implementation on all of this airlines aircraft, a
study was started to see if the numbers of runway incursion and pilot deviation
were being lowered.  While it is possible
to see the population numbers and get an exact look on the year, we wanted to
get a sample size for a small portion of the time it had been working out of
our main airport.  With that it was
decided to analyze flights out of JFK airfield to see what, if any, changes had
occurred due to the new technology.

Evaluation of
NextGen Air Traffic Control Operation with Automated Separation Assurance
by Thomas Prevot, Joey Mercer, Lynn Martin, Jeffrey Homola, Christopher Cabrall
and Connie Brasil.  They discuss problems
with safely increasing the capacity of airspace while describing approaches to
allocating separation with ground-based automation.  They used past task studies and an experiment
simulation of the operation in an air traffic environment.  The researchers used a one-way ANVOA test on
the mean workload of four serperate sectors 
to examine the differences as well as Tukeys Honestly Significant
Differences test.  They developed
conclusions that “Overall traffic density has a primary impact on workload,
safety, and acceptability of the concept. 
The Concept of ground-based automated separation assurance, safety,
workload and acceptability are no longer directly linked to the total aircraft
within a sector.”  This means that based
off of their research, it is possible to accommodate the higher demand of
future air travel. (Mercer, et al., 2010)

Algorithm and
operational concept for solving short range conflicts by H. Erzberger and
K. Heere.  A candidate for the
next-generation sys- tem, referred to as the automated airspace concept (AAC),
incorporates two levels of protection against conflicts and one against
The first level, referred to as the autoresolver, is designed for resolving
conflicts that are ?2–30min to first loss of separation. The second level
of separation assurance handles conflicts that are not detected until loss of
separation is
