People under ADS contract do include non-official waypoints in the FMS routing?
In my airline I would be hanged, drawn and quartered if I did...
(but then again, if given a shortcut (Shanwick don't do that often, but Gander do, west of 50W) does ATC appreciate ADS reports abeam the flight planned reporting points? The Airbus FMS automatically creates those when going directly to a point down route...)
