Published Report (DOT/FAA/CT-94-36)

Controllers also submitted a report documenting their experiences
during the simulation. The controller report is included as
appendix H of this report.
2.3.2 Simulation Pilot Operators.
SPO's operated the TGF aircraft within the various traffic
scenarios. Throughout the simulation, SPO's responded to
controller instructions by entering aircraft heading and altitude
changes using their specialized computer keyboard and display.
SPO's performed their task from the Simulation Pilot Complex in
the TGF at the FAA Technical Center.
2.3.3 Test Director.
Simulation runs and aircraft blunders were under the direction of
the simulation test director. Three individuals assumed the role
of test director throughout the simulation. These individuals
have extensive ATC experience and were trained to work with the
CPA Prediction Tool. The test director was responsible for
initiating blunders based upon the information provided by the
blunder scripts, the CPA Prediction Tool, and his expert
judgment.
2.3.4 Technical Observers.
Four technical observers participated in the DIA simulation. All
technical observers had past ATC experience, and some had FAA
supervisory experience. All technical obsenrers were familiar
with the current MPAP project. Technical observers monitored
controller actions during each simulation run. Their duties
included documenting discrepancies between issued control
instructions and actual aircraft responses; assisting with
alerting responsible parties to correct any problems that may
have occurred during the test (e.g., computer failure, stuck
microphone); assisting controllers with the preparation of
incident reports: and preparing a Technical Observer Report at
the end of the simulation. This report included their opinions
and conclusions concerning the conduct of the simulation as well
as any recommendations to the MPAP TWG. The report is included
as appendix I to this report.
2.3.5 Simulation Observers.
Simulation observers recorded information from the simulation,
such as occurrences of blunders, NBO's, lost beacon signals
(i.e., aircraft that went into coast), and system problems (e.g.,
hardware/software failure, communications, etc.). One simulation
observer was stationed in the Systems Display Laboratory, and
another was located in the area of the test director.
