The test objective of the maneuvering flying qualities evaluation on the OH-6A, OH-58A, BO-105, and L-286 helicopters was to evaluate the suitability of three types of rotor systems (articulated, teetering, and hingeless) to perform the proposed utility tactical transport aircraft system (UTTAS) pull-up and pushover maneuvers. The testing consisted of 41 flights for a total of 22 productive hours. The results obtained during this test established a data base to assess the applicability of the presently stated UTTAS maneuverability requirements. It was determined that present-day rotary-wing aircraft can be tested against the prescribed maneuver criteria with meaningful results. Three flying quality deficiencies were noted, correction of which is mandatory if procurement or envelope expansion is anticipated. There were two shortcomings, correction of which is desirable if procurement or envelope expansion is anticipated.
