screen at all times. The displayed zoom scale can be

determined from the range rings on the arc and 360

displays, or from the distance to the displayed destination

waypoint.

When an approach chart is loaded and being displayed,

the auto zoom mode will limit the low-end zoom level to

5 nm as the current waypoint is being approached. This

prevents the display from zooming into a level where the

overall situational awareness relative to the approach as a

whole is lost. This can be over-ridden by taking the unit

out of auto zoom mode. This limit does not apply when

the auto-zoom mode is tied to the CNX-series GPS

receiver.

Chart Panning

Panning on the loaded chart is currently not supported.

Entering the panning mode will disable the display of the

chart and allow the underlying map layers to be presented.

Chart Orientation

When the chart overlay is presented, the orientation is

identical to the currently selected orientation of the map

itself (North up, track up or desired track up) with

ownship position correctly geo-referenced and presented

on the chart. Note that rotation of the text on the charts

themselves is not supported, meaning that text may not be

oriented horizontally when displayed in track-up fashion.

Chart Info

Pressing the INFO key when a chart is loaded will change

the smart key labels to Header, Profile, Mins, and Info.

Pressing the corresponding keys will allow the different

parts of the chart to be presented along the bottom of the

screen. Pressing the

INFO key will disable this mode and

return the menu to the normal map controls.
