An airworthiness and Flight Characteristics evaluation of the UH-60A helicopter (S/N 82-23748) with the XM-139 Multiple Mine Dispensing System (VOLCANO) installed was conducted by the U.S. Army Aviation Engineering Flight Activity. The tests required 59 productive flight hours. Performance and handling qualities tests were conducted. The change in equivalent flat plate area in forward flight varied as a function of the thrust coefficient and airspeed from approximately 36 to 50 square feet. The out-of-ground effect hover capability was reduced by approximately 520 pounds. The handling qualities of the UH-60A with the VOLCANO installed were slightly degraded when compared to the normal utility configuration. Seven shortcomings were noted in this configuration: the large position error for this ship's airspeed system, the negative longitudinal static stability at 100 KCAS during level flight, the neutral static longitudinal stability during intermediate rated power (IRP) climbs, the neutral to slightly negative maneuver stability above a load factor of 1.4 at 116 KCAS.(sdw)
