Aerospace Operations Systems Program
Pioneer advanced research and technology to enable revolutionary advances in Aerospace Operations Systems to support NASA Goals:
Reduce the aircraft accident rate by a factor of 5 within 10 years, and a factor of 10 within 25 years
While maintaining safety, triple the aviation system throughput, in all weather conditions, within 10 years
Safety
Capacity
Aerospace Operations Systems are ground, satellite, and vehicle systems, and human operators, that determine the operational safety, efficiency and capacity of vehicles operating in the airspace, including:
– communication, navigation and surveillance (CNS) systems;– air traffic management systems, interfaces and procedures;– relevant cockpit systems, interfaces and procedures;– operational human factors, their impact on aviation operations, and error mitigation;– weather and hazardous environment characterization, detection and avoidance systems

Correct Interpretation
Experimental FMA
Control FMA
The aircraft is level at 23,000 ft, the clearance altitude, in VNAV. The crew is waiting for a clearance to 33,000 ft, their cruse altitude.
Observe that there are twoalternative interpretations ofthe Control FMA that are very similar to the correct interpretation.

Human Memory Constraints in Procedure Execution: Predicting Error Vulnerability
1. FMS transitions out of VNAV when altitude capture achieved.

controlled via MCP.
3. Crew fails to recall B757 transition behavior. Results in “Habit Capture”, reversion to B737FMS procedure.
4. Aircraft fails to meet speed target for crossing restriction.

GOAL: To develop interventions to reduce the effects of fatigue, sleep loss, and circadian disruption on flight crews and ATM personnel.
• Original Education and Training Module for Part 121 operations published as NASA/FAA Technical Memorandum: Crew Factors in Flight Operations X: Alertness Management in Flight Operations.
• Initiated piloted simulation to study effectiveness of online, fatigue-dependent feedback to flight crews.
• Completed 747-400 simulator study on effectiveness of in-flight activity breaks on flight crew alertness.
Hourly in-flight activity breaks showed significant decrease in measured sleepiness and increase in reported alertness

• There is a need for a Spatial Standard Observer (SSO) to provide objective measures of visibility and contrast of spatial imagery (e.g., CIE Photometric and Colorimetric Standards)
• Recent multi-lab collaborative data collection (ModelFest) provides a basis for design of SSO
