Detailed Operation
IFR En Route (IFR) Chart Function
The IFR En Route Chart function shows an IFR en route style map for the display. The IFR display shows
navigational aid information and the flight plan course line. The “smart” keys on the bottom of the screen
control zooming in and out, panning, and the display of information on the current TO waypoint. The menu
of options available for the IFR mode include Flight Plan, map orientation, Invert, and turning labels on or off.
This data is advisory only and does not replace primary indicators, such as the CDI. Navigation should not be
based on the data presented on the MX20. Review the Limitations section in the front of this guide.
