    Chart View (CHART) Function (Optional) The optional MX20 Chart View feature provides the capability to view Jeppesen Sanderson Inc. electronic charts. Two basic types of charts can be viewed: Approach charts and airport surface charts. Approach charts can be manually loaded and overlaid on the moving map during flight, while airport surface charts are automatically overlaid while on the ground.

    Detailed Operation Chart View charts, when viewed from the Chart View Function, the aircraft’ s ownship position is not shown on the airport surface chart. If an approach chart is currently loaded and being displayed (aircraft is in the air), it will take priority over displaying the airport surface chart.

  • Page 108: Chart Notams

    Detailed Operation Chart View When an approach chart is loaded and being flown, and the aircraft ground speed drops below the air/ground threshold (set from within the SYS Function), it is assumed that a landing has been performed. At this point, the loaded approach chart is automatically unloaded and the airport surface chart will be presented on the screen showing runways, taxiways, etc.

  • Page 109: Typical Operational Scenario

    Autoloading The GNS 480-series GPS navigator can request the MX20 to load a chart so you only need to select a chart on one device. In most cases, the MX20 will have the same chart in its database and will display the selected chart.
