BONDMAN,
Have used both in the last four years and can honestly say Air Data wins hands down.
As for route construction, no it won't do it for you. (it's random route construction is not great). However if you are sitting down with the charts out, the interface to input the route is actually very user friendly.
These days with the SRS changing every Airac cycle, you generally end up having to tweak your FPL's and Plogs quite regularly anyway. Can SITA automatic plans take SRS into account when constructing a routing?
cheers
