  MIDAS 5.0- The NASA - FAA Closely Spaced Parallel Operations MIDAS Model
           
 

To meet the expected increases in air traffic demands, the Federal Aviation Administration (FAA), the National Aeronautics and Space Administration (NASA), and their industry and academic partners are researching and developing Next Generation Air Transportation System (NextGen) concepts. It is expected that these NextGen concepts will include substantial increases to the data available to pilots on the flight deck (e.g., weather, wake, traffic trajectory projections, etc.) to support more precise and closely coordinated operations (e.g., self-separation, RNAV/RNP, and closely spaced parallel operations, CSPO). These NextGen procedures and operations, along with the pilots’ roles and responsibilities and information requirements, must be designed with consideration of the pilots’ capabilities and limitations. Failure to do so will leave the pilots, and thus the entire aviation system, vulnerable if errors are made.

The objectives of the current research were to develop valid human performance models (HPMs) of approach and land operations; use these models to evaluate the impact of NextGen Closely Spaced Parallel Operations (CSPO) on pilot performance; and draw conclusions regarding flight deck displays and pilot roles and responsibilities for NextGen CSPO concepts. A methodical and comprehensive process was undertaken to develop and validate models of current-day RNAV and NextGen CSPO operations. The models were extended to examine “what-if” off-nominal scenarios. The off-nominal scenarios were then extended to examine candidate roles and responsibilities that could be expected to occur in full implementation of the NextGen. The findings yielded seven primary guidelines and implications for candidate NextGen roles and responsibilities and flight deck displays and automation.

The movie file of the CSPO model shows the external environment on the leftmost side, the microsaint sharp task network model of all of the tasks grouped by phase of flight in the simulation in the middle panel, and the Jack model of the Co-Captains responsible for the ownship of the simulation. The lead aircraft progressing towards the SFO runway is shown in the left panel. The active primitives, the operator responsible for the active task on the flight deck as well as the air traffic controllers, the context driving the model, the phase of flight task groupings, the code embedded in some of the individual tasks that drive the attention model (Salience, Expectancy, Effort, Value) including the task importance and the cost of interruption per crew member, the runtime workload and situation awareness model output is shown in the middle panel. The Jack model visualization of the flight deck crewmember scan patterns and the crewmember interaction on the flight deck is shown in the right most panel.
