Welcome to Emerald Sky Technologies (eSky)
eSky was formed to develop advanced general aviation avionics for the 21st century.   

eSky is your source for the OZ primary flight display (PFD), 
a graphical representation of critical flight information that replaces images of 1929's best instruments with graphic symbols that virtually eliminate scan and are provably superior to the traditional six-pack or integrated PFD.  A downloadable, Microsoft Flight Simulator X compatible version of OZ is available to explore OZ and its capability. 

A tutorial is also available on the Download Page as an aid to learning the OZ symbology.
