Definition
On a Multi-Function Display (MFD), page groups are the top-level categories of information screens organized by function — such as Map, Waypoint, Auxiliary, and Nearest. Each page group contains a set of related individual pages the pilot can cycle through to access specific data.
Plain English
The MFD organizes its screens into a few main categories. Each category holds several related screens, and you move between categories first, then between screens inside a category.
Context Anchor
Seen when navigating the pages of a multifunction display, especially when using knobs or display buttons to reach map, flight plan, weather, traffic, or system information.
Why Pilots Care
Reduces head-down time and mental workload by letting pilots reach needed data without scanning through unrelated screens.
Analogy
Think of page groups like tabs in a web browser, where each tab contains several pages you can scroll through. You pick the tab first, then the page within it.
Intuition Check
Do not think of page groups as paper pages. In this context, a page group is a set of related electronic screens on the aircraft display.
Example Sentence 1
The instructor showed the student how to rotate the outer knob to switch between page groups on the MFD.
Example Sentence 2
During the approach briefing, she selected the flight-plan page group to review the arrival routing.
