(3) Special Symbols
Because of space constraints on the screen, the MCDU uses a number of special
symbols to indicate actions:
• < and > appear at the far left or right to indicate that another menu page is
available in that direction or that a function is available for that label.
• NUMBER/NUMBER appears to tell you which page out of how many pages you
are viewing. For example, 1/3 would appear when you are on page 1 of 3 pages
in total.
(4) Navigating the MCDU
The MCDU includes a number of menus, as shown in Figure 2-2.
