• Are there collaborations being established to accomplish goals in Global Positioning System procurement?

ENVIRONMENTAL MANAGEMENT

  • NextGen ideas run from totally automated execution to totally human (manual) execution.

    • Research is needed to identify human factors issues now.

    • It is particularly important to focus on who is in charge.

    • The environmental challenge is both an execution issue and a policy issue.

    • NextGen is a technology issue (i.e., what is possible?)

  • Are there any radically different or revolutionary ideas about what constitutes an aircraft (e.g., modular airplanes or systems)?

  • Does the plan take into account how new systems enter the aviation system?

    • Can planners be opportunistic in introducing new functionality?

    • How can the changes that systems must accommodate be limited to one rather than several?

  • Is there concern with legacy aircraft and/or concern with continuing to hire for the current air traffic management system rather than for future aircraft and NextGen?

  • Is it recognized that having only one concept for the future is a problem?

  • What skills will be needed 10 years out?

  • What human factors work is needed to understand what criteria are important to guide hiring?

POSITIONING, NAVIGATION, TIMING SERVICES, AND SURVEILLANCE

  • Can the Department of Homeland Security (namely, the Coast Guard) help by providing a standard for the enhanced long-range navigation system (eLORAN)?

  • What are the developmental issues for eLORAN?

  • What is the performance of the systems? What are the limits on accuracy? How much can be invested? Do systems have backward compatibility?

  • How will satellite constellations and their placement affect performance?

WEATHER INFORMATION SERVICES

  • The current system is brittle. Failure can suddenly occur when perturbations occur in the system (e.g., bad weather). Can JPDO “spec out” a less brittle system?

  • Is there any research that is investigating the extent to which a conflict between “official” and “airline” sources of weather information will lead to problems?

  • What research will be done to explore necessary levels of spatial and temporal resolution?

  • What happens when a pilot is routed through a weather cell?

    • What is the impact on other planes routed in that area?

    • What is the pilot’s responsibility for decision making on going through a cell?

    • Are clearances/trajectories advisory or compulsory?

  • How does the industry develop insurance for mitigation of risk?

  • Is there any research planned to investigate consumer reaction to changes in departure times for weather/other potential delays?

  • Is sufficient research being planned and conducted in the areas of data handling and communications as applied to weather information?
