Two of three inflatable bags used to lift NASA’s G-III research aircraft during loads testing in NASA Armstrong’s Flight Loads Lab were positioned under the wing root area; the third under the rear fuselage. With an operating pressure of only 3.5 psi, each airbag is capable of supporting 12 tons. The airbags helped isolate the airframe from any potential influence of the landing gear on strain-gage data during the loads tests.
