We use the full LIDO eRoutemanual for quite a few years now on our aircraft installed EFBs, full GEN (including Company GEN), airport and enroute charts (low and high level, all charts interactive on the class II EFB).
The big point would be to have the ability to preview charts outside the aircraft if its available on the iPad. We do have access over the internet to the full route manual, but that is only online via a web site which can be very expensive abroad.
