Each floor is clearly marked.
The floor being viewed is displayed in bold.

Icons indicate facility locations.

This is the floor map. The sections in yellow are open to the public.
The sections in orange are only open to passengers boarding or disembarking from aircraft.

Clicking on the icons will show or hide the locations of the relevant facility on the map.
If that facility is not available on that floor, it will be displayed in grey.

These buttons can be used to adjust the size of the display by zooming in or out, or going back to the original size.
The highlighted section can also be moved by clicking and dragging.
