This paper describes how the USAF's 309th Software Maintenance Group (SMXG) at Hill Air Force Base developed the PATS (Portable Automated Test Set)-70 which supports the testing of various A-10/C systems on the flightline. Based on Marvin Test Solutions' MTS-207, a state-of-the-art, ruggedized, portable PXI-based platform designed for flightline, back shop, and airborne applications, the MTS-207 provided the USAF with the necessary flexibility to add a specific test instrumentation, such as GX6315 and GX2065 PXI cards for supporting the A-10/C's specific flightline test needs.
