    This paper designed a 1553B interface card for the sampleflight simulation computer. The detail schematic of the interface card is given out. The card use Cyclone III FPGA as processor and receive sensor data of 1553B from the exterior Avionics System. Data preprocessing converted the sensor data into data format of FlexRay. Then transmit the data to CPU card by FlexRay bus which is the flight control computer internal bus. Thisimplement a solid hour of the communication between external devices and the flight control computer. The experiment verified the correctness of the design and can provide 1553B communication interface for the new distributed UAV flight simulation computer.
