“…Under VFR, the pilots are responsible for maintaining safe separation distances. Under IFR, theAir Traffic Controllers (ATC) areresponsible for maintaining the separation distances mandated by the FAA [1]. When conditions require an airport to operate under IFIL the airport capacity is significantly diminished.…”

Several of our major airports are operating at or near their capacity limit, increasing congestion and delays for travelers. As a result, the National Aeronautics and Space Administration (NASA) has been working in conjunction with the Federal Aviation Adminiswation (FAA), airline operators, and the airline industry to increase airport capacity and safety. As more and more airplanes are placed into the terminal area the probability of encountering wake turbulence is increased. The NASA Langley Research Center conducted a series of flight tests from 1995 through 1997 to develop a wake encounter and wake-measurement data set with the accompanying atmospheric state information. The purpose of this research is to use the data from those flights to compute the wake-induced forced and moments exerted on the aircraR. The calculated forces and moments will then be compiled into a database that can be used by wake vortex researchers to compare with experimental and computational results.

An overview is presented of the development, use, and current flight-test status of a highlyinstrumented North American Rockwell OV-10A Bronco as a wake-vortex-hazards research aircraft. A description of the operational requirements and measurements criteria, the resulting instrumentation systems and aircraft modifications, system-calibration and research flights completed to date, and current flight status are included. These experiments are being conducted by the National Aeronautics and Space Administration as part of an effort to provide the technology to safely improve the capacity of the nation's air transportation system and specifically to provide key data in understanding and predicting wakevortex decay, transport characteristics, and the dynamics of encountering wake turbulence. The OV-10A performs several roles including meteorologicalmeasurements platform, wake-decay quantifier, and trajectory-quantifier for wake encounters. Extensive research instrumentation systems include multiple airdata sensors, video cameras with cockpit displays, aircraft state and control-position measurements, inertial aircraft-position measurements, meteorological measurements, and an on-board personal computer for real-time processing and cockpit display of research data. To date, several of the preliminary system check flights and two meteorological-measurements deployments have been completed. Several wakeencounter and wake-decay-measurements flights are planned for the fall of 1995.
