The automatic flight control system of modern civil aircraft is one of the primary human-machine interaction systems, and its flight mode operation control function consists of two main physical components: FMCP hardware and automatic flight control software. For the validation of complex human-machine interaction functionalities, an approach oriented towards the development process is necessary. Firstly, the development architecture of flight mode operation control functions was decomposed step by step from the system functional level to the functional module level. Then, an architecture for verifying the flight mode operation control functions was designed from the functional module level to the system functional level, in a bottom-up manner. Finally, focusing on the integrated model testing phase within the functional verification architecture, taking the example of FMCP speed window function, all relevant human-machine interactions were categorized and defined. The state transitions and action responses for speed target values were defined separately, and a comprehensive matrix of state transition and action response of speed target value was sorted out based on the definitions. Each table in the matrix corresponds to the state transition or action operation of the speed target value and its corresponding response situation. This provides a reference for the integrated model validation of automatic flight mode operation control.
