The pilot operational procedures (POP) defines the display interface and operation logic of the avionics system. It is the most important top-level design document for avionics integrated design, and its simulation has an irreplaceable role in supporting the overall design. The display control interface of the avionics system is the main human-machine interaction interface of pilots. The optimized and convenient display control interface can significantly improve the pilot’s operational efficiency and reduce the pilot’s workload. The size of the aviation radio stands built is too large, which makes it difficult to communicate with front-line pilots, optimize and train air and ground crews. Portable equipment is easy to carry and display, which provides convenience for designers. Firstly, the composition and task operation of POP were explained from the perspective of the integrated avionics system of a certain aircraft model, and then the steps of establishing POP simulation model were introduced. Finally, the integrated avionics system POP was simulated, and a portable POP simulation platform was built. The results can be used to support display interface design and communication with pilots during the system design process.
