TECHNICAL ABSTRACT (Limit 2000 characters, approximately 200 words)
Trajectory-based operations constitute a key mechanism considered by the Joint Planning and Development Office (JPDO) for managing traffic in high-density or high-complexity airspace in the Next-Generation Air Transportation System (NextGen). With this concept applied to surface operations at major airports, NASA's NextGen-Airportal Project is exploring the use of surface 4-dimensional (4D) trajectories, which use required times of arrival (RTAs) at selected locations along the route. Observing these RTAs as constraints along the taxi route, the flight still has many degrees of freedom in adjusting its state profiles (i.e., position, velocity, etc. as functions of time) to achieve the timing constraints. This research will investigate whether and how these degrees of freedom in trajectory control may be used to achieve desirable behaviors for the taxi operations. Previous research has applied the trajectory control freedom to assure passenger comfort by keeping the accelerations and decelerations within pre-specified limits, and yet there is still untapped flexibility in designing the trajectories. The proposed research will explore this trajectory design problem to achieve additional desirable behaviors, beginning with the consideration of fuel burn, emissions, and noise. A flight-deck automation experimental prototype will provide the platform for simulating the designs, augmented by models developed to evaluate environmental benefits. The findings will benefit future designs of flight-deck automation systems, as well as tower automation systems which rely on accurate understanding of the flight deck's operational behaviors to plan efficient and safe operations for the entire surface traffic.

POTENTIAL NASA COMMERCIAL APPLICATIONS (Limit 1500 characters, approximately 150 words)
The proposed research contributes directly to trajectory-based surface operations (TBSO), which constitute an important area of research being pursued by the NextGen-Airportal Project under NASA's Airspace Systems Program. The research will produce realistic and favorable surface 4D trajectory designs to enable TBSO. Sharing these design models with the control tower will allow its automation system to plan safe and efficient operations, and enhance separation assurance by using the models to infer intent when monitoring the traffic movements.

POTENTIAL NON-NASA COMMERCIAL APPLICATIONS (Limit 1500 characters, approximately 150 words)
Whereas NASA's NextGen-Airportal Project investigates innovative new technologies, approaches, and procedures to enable capacity enhancements within the airport and terminal domains to meet the JPDO NextGen capacity goals, products from the proposed research will contribute to this cause. The research findings will strengthen the understanding of flight-deck automation potentials for trajectory-based surface operations (TBSO) to help avionics companies design and develop flight control systems that enable such operations. Knowledge of the flight-deck automation will also help developers of air traffic management systems develop control tower automation to realize the full potential of the TBSO concepts. NASA research products, including the technologies envisioned from the proposed research, can be transferred to the FAA through the Research Transition Teams (RTT) set up between NASA and the FAA, to promote transition of these products to real-world applications and acceptance.
