mile full scale, one pixel width on the Navigator display equals approximately 25 feet of course deviation.
The Navigator can be configured to display the internal CDI sensitivity in nautical miles, statute miles or
kilometers. See Section 3.2.2.5 for information on setting user units.
NOTE: The Internal CDI will always be less than or equal to the external setting. For example, if the internal
CDI is set to 2.5 nm and the external CDI is set to 1.0 nm, both will be set to 1.0 nm.
