[0002] Backup flight displays are a critical safety device on aircraft, used to provide a backup display function when the primary flight display fails.

[0003] The backup flight display includes a multi-function keypad, primarily providing pilots with backup display and parameter setting functions in the event of a failure of the main touchscreen display. The backup flight display allows switching between displays for the horizon, compass, electromechanical systems, and parameter settings via peripheral keys, while the multi-function keypad allows for setting parameters such as radio communication and navigation.

[0004] There are two existing structures for backup flight displays: The first is a stand-alone multi-function keyboard. In this design, the keyboard and display are separate, connected via a cable with connectors at both ends. The disadvantages are: a separate keyboard bracket structure is required, or the bracket structure must be integrated into the keyboard structure; additionally, a cable with connectors at both ends is needed, significantly increasing costs. The second type is an integrated multi-function keyboard. In this structure, the keyboard is integrated into the display panel, sharing a single housing. Therefore, the overall size of the display is much larger due to the integration of the keyboard, resulting in a larger footprint on the instrument panel. Utility Model Content
