"An investigation with a variable-stability helicopter was undertaken to ascertain the steadiness and ability to "hold on" to the target of a helicopter employed as a gun platform. Simulated tasks were per formed under differing flight conditions with the control-response characteristics of the helicopter varied for each task. The simulated gun-platform mission included: Variations of headings with respect to wind, constant altitude and "swing around" to a wind he ading of 0 deg, and increases in altitude while performing a swing around to a wind heading of 0 deg. The results showed that increases in control power and damping increased pilot ability to hold on to the target with fewer ya wing oscillations and in a shorter time. The results also indicated that wind direction must be considered in accuracy as sessment. Greatest accuracy throughout these tests was achieved by aiming upwind." ; Prepared at the Langley Research Center, Langley Field, VA. ; Cover title. ; "September 1960"--Cover. ; Includes bibliographical references. ; "An investigation with a variable-stability helicopter was undertaken to ascertain the steadiness and ability to "hold on" to the target of a helicopter employed as a gun platform.
