Lateral (and vertical) deviation scales are not the same for all GPS 
units.  To determine the course widths for each mode refer to the 
manual for the GPS that is installed in each particular aircraft. 
 
For deviation values outside the limits of the scale, the deviation 
pointer parks at the end of the scale closer to the deviation value. 
When lateral deviation is invalid the deviation needle is replaced with 
a red X.

Two green bearing pointers that point to the selected NAV source 
are displayed.  The source is either VOR or GPS.  When VOR is 
selected, the pointer indicates the relative bearing to the selected 
NAV facility. When GPS is the source, the pointer points to the active 
waypoint in the flight plan.
