well, since they mention this accident specifically and then go on to wash their hands of any responsibility for the accuracy of such databases, it sounds like someone is making sure they aren't to blame should it turn out the database was flawed and was a significant contributory cause.
ED76 and DO200A in my experience ensure the integrity not the veracity of the data. Therefore for a company route, the data would still have to be ensured by the operator. As for the terrain data it comes from a government authorised source. The procedures, to my eye, allow an operator to use processed databases without having to independently verify them.
Thanks 212man, I'll be interested whether the "company route" in the FMS made use of altitude constraints even if it was only a reminder on the control and display unit.
