Abstract	Current Project: Pilot Behavioral Models for Simulating Flight Operations Near Ships Sponsored by NAVAIR, Contract N68335-05-C-0054, TPOC Susan Polsky, AIR 4.3.2.1 Project team members include Ron Hess, Dave Mitchell, and Simon Bourne. NAVAIR's Advanced Aerodynamics Branch is developing CFD-generated models of the airwake environment around air-capable ships. Pilot behavioral models offer a means for examining, via computer simulation, a variety of terminal flight operations in the context of the overall task-pilot-vehicle (TPV) combination. In particular, the TPV models can enable better evaluation of the airwake models than, say, an open-loop aircraft in the same environment. The pilot models perform terminal flight tasks according to Navy procedures. The basic model architecture consists of a feedback control structure that contains three elements, the task, pilot, and vehicle—a structure that is identified as the TPV model form. The task is a mathematical construct of a specific operation such as approach and landing on a destroyer or aircraft carrier as defined by standard Navy procedures (NATOPS manuals). The task also includes the associated cueing, navigational aid, and guidance. The vehicle consists of a specific aircraft simulation math model. In this case we use vehicle models that reside in the NAVAIR Manned Simulation Facility environment. Finally, the pilot is represented as a structural perceptual-motor model that produces manipulations of the primary and secondary flight controls based on available cues, task procedures and pilot decisions for transitioning from one segment to the next. We are nearing the halfway point in the two-year Phase II project. Pilot models for fixed-wing and hovering vehicles are being implemented in the Navy's CASTLE simulation environment. Pilot models are installed in the F/A-18 and SH-60 simulatory math models and soon in the MV-22 and AV-8. At the ACGSC meeting we demonstrated short movies that illustrate the pilot models operating the F/A-18 and SH-60. Also we listed the steps used to validate the pilot models. At future meetings we will present movies showing complete terminal tasks and effects of ship airwake disturbances.
