Icing of fuel system is a key problem in air transportation, which is related to the safety and reliability of flight. This paper mainly introduces the relevant standards, regulations and research progress of icing in engine fuel system. On the one hand, combined with domestic and foreign relevant standards and icing test process and other aspects, the similarities and differences of civil aircraft and military aircraft in design criteria are described. On the other hand, the latest progress of icing research on fuel system is described in detail from the aspects of icing mechanism, ice growth and adhesion test. Finally, the paper points out that the green, intelligent and fine icing test standard of engine fuel system will be the key research direction in the future, and the related research of engine fuel system icing is prospected.
