Final answer:
A synoptic page on an MFD can usually be accessed by pressing the "SYNOPTIC" button, but depending on the design and software of the MFD, it may also be available through other means such as the "DISPLAY" menu, "SETTINGS" tab, or a "MAP" option.
Step-by-step explanation:
A synoptic page on an aircraft's Multi-Function Display (MFD) can typically be accessed by selecting the "SYNOPTIC" button. The MFD is a key component in modern aircraft cockpits that provides pilots with a centralized and easily accessible location for airplane data. This data can include various system diagnostics and status reports for the aircraft's various systems such as electrical, hydraulics, and fuel. If the synoptic pages are designed to be within a categorized grouping on the display, this could alternatively be through a "DISPLAY" menu where you could select the specific system synoptic page you are interested in viewing. In some advanced systems, there may also be options within a "SETTINGS" tab to configure which synoptics are displayed or how they are displayed. Lastly, some systems could integrate synoptic information within a "MAP" option to show relevant systems data overlaid on navigational displays, though this would be less common for a dedicated synoptic page.
