To ensure the fight safety of the modern large-scale civil aircraft, ground simulation test has become an important role for the successful development of the aircraft. In this paper, the construction principle of the full machine level integrated verification test platform is pointed out, the plan of iron-bird test rig, avionics test rig and power test rig is described as well. Through the interconnection of test pieces, the interconnection of test equipment and the grounding technology, the different test rig is connected to form the whole machine level integrated test platform.
