Automation Adoption and Adaptation in
the Air Traffic Control,

URET Case Study

Tatjana Bolic

2


Problem Statement and Goal


Capacity constraint, improvements in form of
Decision Support Tools (DSTs)


Incremental development of Air Traffic Control (ATC)
system in USA


Unexpected consequences


Need to know more about adoption of automation in
ATC


to facilitate easier and faster transitions from
one system to another


Goal


to assess the automation adoption by air
traffic controllers

URET Description


Three displays


Conflict probe


Trial plan


Automated route amendment


5


URET Description


Aircraft List and Plan display


electronic flight strips



Graphic Plan display



Wind Grid display




6


URET Description


Usage variation:



Different teams use it in a different way


Usage differs from the intended usage


Usage differs across centers


7


URET Diffusion


Diffusion of innovation
: “
is the process by
which an innovation is communicated
through certain channels over time among
the members of a social system “



4 elements:


Innovation
-

URET


Communication channels


inter personal and
inter facility FAA networks


Time


length of URET usage


Social system


individual en
-
route facilities




8


URET Diffusion


Social system norms


Innovation characteristics:


Relative advantage


Compatibility


Complexity


Trialability


Observability


Adaptation: “
the degree to which an innovation
is changed or modified by a user in the process
of its adoption and implementation “

URET Issues



False conflict alerts


Training


15


Hypotheses


Hypothesis 1:
The longer the controller
uses URET, the more complete his use
of its capabilities will be.


Time

Learning

16


Hypotheses


Hypothesis 2:
Quality and depth of
training will affect the use of URET.


17


Hypotheses


Hypothesis 3:
New controllers will use
all main functionalities more than the
old controllers.



18


Hypotheses


Hypothesis 4:
Adaptation of URET use
will result when controller works the
sector alone, and if the controller works
alone most of the time, the adaptation
will be even more pronounced.


19


Hypotheses


Hypothesis 5:
Strategic environment is
more suited for full URET use than the
tactical environment.

Hypotheses


Hypothesis 6:
D
-
side controllers who
use the full URET functionality will offer
conflict resolution to their R
-
side
controller more often than D
-
side
controllers who don’t use the full URET
functionality.


21


Conclusions and
Recommendations


Adoption and adaptation of automation
not new


not applied in ATC


Use diffusion of innovation to
investigate innovation adoption in ATC


Future work
-

Survey development and
administration
