The US Army Aviation Engineering Flight Activity conducted a limited Airworthiness and Flight Characteristics test of the RC-12D Improved Guardrail V aircraft with both standard and infrared IR suppressor exhaust stacks installed from 10 May though 1 June 1984 at Wichita, Kansas. During the test program, 12 flights were conducted for a total of 25.7 hours, of which 14.6 were productive. All tests were performed in a normal mission configuration ballasted to a maximum takeoff gross weight of 14,200 pounds and a center of gravity at fuselage station 190.1 fwd. Test results were compared with data obtained during previous testing, and evaluated against military specification MIL-F- 8785C. Takeoff and landing performance presented in the operators manual were confirmed as was the Beech Aircraft Corporation provided drag polar plot of the standard stack configured aircraft. A slight degradation in performance was noted with IR suppressor exhaust stacks installed. The RC-12D aircraft has marginal climb performance capabilities with a combat ceiling below 24,000 feet density altitude. The handling qualities of the RC-12D with both standard and IR suppressor exhaust stacks installed were essentially unchanged from the standard C-12D aircraft with the exception of improved stall characteristics.
