The Data Bar is the strip of data that is displayed across the top of the AXIS™ flight display. It is able to display many
pertinent fields of data for the pilot to have quick reference to. Up to eight fields of data
from the following list can be displayed across the top of the screen. The amount of data
fields displayed depend upon the amount of space available on the CNS bar. If, for example,
only one communication radio and one navigation radio are displayed, the amount of available
space in the upper portion of the screen is enough to display eight fields of data. If the
Emergency Button (EMER) is then enabled to be displayed, the space at the top of the screen is
prioritized to fit the most pertinent information, consequently removing the last data field
from the data bar.
