‡ Only presented as an option if the AeroNav is configured to
communicate with an external fuel flow system
To restore factory defaults to the datablock selections, press the
bottom right AeroNav knob while on the Datablock Setup page
and then accept the green Confirm dialog box that gets displayed
or use the Presets selection in the "Datablock" LSK.
TIPS AND TECHNIQUES
Selecting Desired Datablocks
If a desired datablock selection is grayed out in the
selection box, that means there isn't currently
enough room to put it in the desired location. One
technique is to delete datablocks below the desired
location in order to make room. Each new datablock
selection will push older ones below it "down the
stack".
