Abstract	HAI is in the final stages of development of an expert system for the application of ADS-33E-PRF, the military specification for rotorcraft handling qualities. Under a Phase II.5 SBIR from NAVAIR, the ADS-33 Specification Assistance Package (ASAP) will pre-process input data from many different sources and formats; compute time- and frequency-response parameters; and assist the user with interpreting the results when those parameters are compared with the requirements of ADS-33E-PRF. A Beta version of the software, running in MATLAB, should be released this Fall. In support of the ASAP development, HAI is helping the Navy in flight test evaluations of handling qualities of large cargo helicopters, focusing on slung-load operations. Testing is ongoing at Patuxent River with a CH-53E. HAI is also developing a display system for evaluations of handling qualities for helicopter shipboard launches and recoveries. Based around the Superslide developed by the Canadian National Research Council, the portable display will be an electronic board that will be programmable for different ship motions and Sea States. HeliSAS, the low-cost, lightweight helicopter SAS system developed by HAI, is finally about to get an FAA Supplemental Type Certification for the Bell 206, and more STC’s should follow shortly. HAI has just completed a survey of UAV designers and users for the Navy. This survey confirmed the need for dedicated UAV flying characteristics design criteria and requirements. Dave Mitchell, the Technical Director at HAI for the past 17 years, has left the company to start his own business part-time, and to work for another small business part-time.
