It has nevertheless been used on a temporary approval at WPC 2009, WMC 2009 and EMC 2010 with great success.
It is estimated the software modifications will be done some time in the winter 2010-2011 and full approval will be sought before the 2011 European flying season starts.
This is a java application which works on both PC's and Macs. The latest version is always maintained on the FRDL website and includes full instructions.
