A NASA University Research Center Achieve broad-based, competitive aerospace research capability among the nation's minority institutions Foster new aerospace science and technology concepts and expand the nation's base for aerospace R & D Increase the participation of socially and economically disadvantaged students in STEM careers
What is CHAAT?
CHAAT Research Goals• Metrics for operator situation awareness,
workload and performance in NextGen• Part-task simulations for identifying the most
promising automation concepts• Information requirements and critical task
components for training future NextGen operators
• Design recommendations for human-machine interfaces
CHAAT Education Goals• Attract and train more students in NASA-
relevant majors (especially minority and underrepresented groups )
• Inspire K-12 students to pursue STEM careers.
• Opportunities for faculty collaborations between NASA and other universities
Overview: NextGen
NextGen changes: • Roles and responsibilities
between air and ground operators
• Automation technologies • CONOPS• Increased reliance on
automation
Changes affect:• Situation awareness• Workload• Performance
CHAAT:• Metrics for operator situation awareness, workload
and performance in NextGen• Part-task simulations for identifying the most
promising automation concepts• Information requirements and critical task
components for training future NextGen operators • Design recommendations for human-machine
interfaces
Comprehensive Overhaul of NAS
• increase capacity • improve safety• increase reliability
Distributed Simulation?

Why: Cognitive Fidelity*• Degree to which the simulated task environment
places cognitive demands on operators that are comparable to those experienced in operational settings
Implications for Human-in-the-Loop (HIL) Simulations • Simulations must place demands on information
acquisition and integration, decision making, problem solving, etc.
• Involves simulators and task environment
NextGen Simulations** • Cognitive fidelity achieved by:
• Automating roles that are not the focus of the researchAdding more role players to
the simulationEducational Benefit• A valuable tool for training the
future workforce in human factors and NASA-relevant STEM technologies
What: Human-in-the-loop simulations over the internet when operators and/or participants are located at remote sites
Distributed Simulation CHAAT- FDDRL
Multi-aircraft Control System (MACS)• Used for simulations, rapid prototyping,
and concept evaluation• Can be configured for several operating
modes: • ATC en route, ATC TRACON, pilot,
pseudopilot, simulation manager, etc.)
Aeronautical Datalink and Radar Simulator (ADRS) • Routes information amongst client
processes during a simulation• Provides data about precise aircraft
positions and states, flight plans, etc.
Software: MACS and ADRS from NASA AOL (Prevot, 2002)
MACS DSR Mode MACS Simulation MangerMACS Single Pilot Mode
Software: 3D-CSD and DagVoice from FDDRL 3D Cockpit Situation Display (CSD) (Grandada et al., 2005)• Volumetric representation of the
surrounding 3D traffic environment, • Terrain, weather, CD&R, spacing
DAGVoice (Canton et al., 2005)• Multicast, multichannel, voiceIP
communication system • Emulates pilot and ATC radio
communications
Distributed Master - FDDRL (George Lawton)
Capabilities• Integrates simulation system start-up using
single interface • Send commands using script-based code• Provides system-wide status feedback• Updates simulation software on all stations• Finds, copies, and transfers data to file serverAdvantages• Reduces number of points of failure• Provides control over system start-up and
shutdown• Provides basic system error alerting• Enables minimally-intrusive remote
troubleshooting and system restart control• Easy and consistent data archiving function
CHAAT Simulation Capability Benefits NASA• A flexible high-cognitive-fidelity HIL simulation capability
at a reduced cost• NASA FDDRL has expanded its flight deck simulation
capability by adding pseudopilot stations and an ATC center for its simulations of flight deck automation tools without adding physical components and personnel
– CHAAT has served as ground control for several FDDRL simulations of pilot merging and spacing operations in the presence of weather.
– Hardware, software, and trained operators available for all simulation roles– Operators obtained from retired ATCs in the community, student ATCs from
MtSAC, and students at CSULB who are studying human factors
CHAAT Remote-Site Support of NASA FDDRL Simulations • Distributed Simulation of UAS’s Flying in Terminal Airspace (2006)
• Trajectory Oriented Operations with Limited Delegation during Convective Weather (TOOWiLDx) Simulation Demonstrations (2008)
• Evaluation of Automated Spacing Support Tools for Interval Management Operations under Hazardous Weather Conditions (2009)
• Situation Awareness and Workload with Trajectory Oriented Operation in Weather I and II (2009)

A Distributed Simulation: NASA and Three Universities
CHAAT On-Site Support of NASA Simulations• FDDRL
– Five students support FDDRL simulation project WATERSHED (2011)
– Four students and faculty support FDDRL simulation project SAFARI (2010)
– Three students support FDDRL Audio Twitter simulation project (2009)
• FDDRL and AOL– Three students support air-ground simulation of off-nominal
events (2008)• Aviation Systems Division
– One student supports UAVs flying in high altitude airspace simulation (Access-5)
Educational Benefits of Distributed Simulation
Distributed Simulation
“Hands On” Distance Learning
CHAAT Students • Interact with NASA scientists remotely and directly
• E.g., CHAAT interns trained at CSULB prior to arriving at NASA• Students graduate with expertise and experience in
• Basic and applied research and experimental design• Airspace operations (air and ground)• Simulation development and analysis• Scenario development• Airspace human factors
•NASA and aerospace industry get workforce with “known” capabilities
CHAAT Students Benefit from NASA Software• 4 student theses in progress based on MACS and CSD
• Over 40 graduate/undergraduate students trained in NASA software, simulation techniques, airspace operations and human factors
• Over 60 students from MtSAC have gained radar experience prior to entering the FAA Academy
• Approximately 20 eighth-grade girls were exposed to ATC operations and NASA software
