FLIGHT EVALUATION OF THE NEW HANDLING QUALITIES CRITERIA USING THE BO-105

The Aeronautical Design Standard ADS-33C is a proposed US Army/Navy ha ndling qualities specification for rotorcraft. The DLR at Braunschweig has conducted a partial evaluation of the quantitative forward flight criteria of the ADS-33C by flight testing an unaugmented BO 105 helic opter. This paper describes the flight test and evaluation methods use d to obtain the parameters needed for determining handling qualities l evels. Applicability and repeatability of the criteria are also discus sed. Handling qualities parameters that augment existing handling qual ities databases are provided. Finally, some problem areas are identifi ed and improvements are proposed.
