A predominant research focus in the free flight community has been on the type of information required on the flight deck to enable pilots to "autonomously" maintain separation from other aircraft. At issue are the relative utility and requirement for information exchange between aircraft regarding the current "state" and/or the "intent" of each aircraft. This paper presents the experimental design and some initial findings of an experimental research study designed to provide insight into the issue of intent information exchange in constrained en-route operations and its effect on pilot decision making and flight performance. Two operational modes for autonomous operations were compared in a piloted simulation. The tactical mode was characterized primarily by the use of state information for conflict detection and resolution and an open-loop means for the pilot to meet operational constraints.

Two operational modes for autonomous operations were compared in a piloted simulation. The tactical mode was characterized primarily by the use of state information for conflict detection and resolution and an open-loop means for the pilot to meet operational constraints. The strategic mode involved the combined use of state and intent information, provided the pilot an additional level of alerting, and allowed a closed-loop approach to meeting operational constraints. Potential operational benefits of both modes are illustrated through several scenario case studies. Subjective data results are presented that generally indicate pilot consensus in favor of the strategic mode.Wing, David J. and Adams, Richard J. and Duley, Jacqueline A. and Legan, Brian M. and Barmore, Bryan E. and Moses, DonaldLangley Research CenterAIR TRAFFIC CONTROL; DECISION MAKING; FEEDBACK CONTROL; AUTONOMY; FLIGHT OPERATIONS; EXPERIMENT DESIGN; FREE FLIGHT

RTCA Special Committee 186 has recently adopted a series of changes to the original Minimum Aviation System Performance Standards (MASPS) for Automatic Dependent Surveillance Broadcast (ADS-B). The new document will be published as DO-242A. Major changes to the MASPS include a significant restructuring and expansion of the intent parameters for future ADS-B systems. ADS-B provides a means for aircraft to exchange information about their intended trajectories with each other and with ground systems. NASA and Boeing have played significant roles in recommending these changes and providing supporting analysis. The intent changes are anticipated to provide substantial benefits to several programs and operational concepts under development by the two organizations. Major changes include the addition of Target State reports and the replacement of Trajectory Change Point reports with Trajectory Change reports.

An essential element in the Free Flight concept is the detection and avoidance of air traffic conflicts. A conflict occurs when the required separation between two aircraft, namely the ownership and the intruder, is lost. Conflict detection and resolution systems predict loss of separation and output conflict avoidance maneuvers that divert the ownership from its original trajectory. In this paper, we address the problem of redirecting the ownership to its original path, in a geometric optimal way, without introducing new conflicts. We call this concept Resolution and Recovery. Given the current 3-dimensional position and velocity vectors of two aircraft in predicted conflict and the ownership's required time of arrival at the target point, the resolution and recovery algorithm outputs a choice of maneuvers. Each maneuver comprises an escape course and a recovery course to be followed by the ownership. The escape course brings the ownership off the predicted conflict and the recovery course returns it to the original target point. We provide a rigorous mathematical description of the problem and show that the algorithm is correct, i.e., no matter which of the proposed maneuvers the ownership picks, it will arrive at the target point at the scheduled time while maintaining the minimum required separation to the intruder at all times.

The National Research Council (NRC) of the National Academies was asked by NASA and the Office of Management and Budget to perform an assessment of NASA's Aerospace Technology Enterprise. The first such review, which began in early 2002, examined Pioneering Revolutionary Technology (now known as Mission and Science Measurement Technology). The assessment presented here, of the Aeronautics Technology Programs, began in early 2003 and is the second in the review series. The Aeronautics Technology Programs has three components: the Vehicle Systems Program, the Airspace Systems Program, and the Aviation Safety Program. To conduct this review, the NRC established three panels, one for each of the component programs. The NRC also established a parent committee, consisting of the chairman and a subset of members from each panel. The committee and panels comprised a cross-section of experts from industry, academia, and government and included senior-level managers and researchers in the aeronautics field. Biographical information on the committee and panel members is found in Appendix A. Review of NASA's Aerospace Technology Enterprise: An Assessment of NASA's Aeronautics Technology Programs contains the committee's assessment of the Aeronautics Technology Programs. Chapter 1 presents a top-level assessment, and Chapters 2 through 4 provide the assessments of the Vehicle Systems Program, the Airspace Systems Program, and the Aviation Safety Program, respectively.
