With regards to the Paris computer not having all the aircraft types, surely it's the airline's operations people that sends out the initial flightplan to all the enroute adressees, and that should be the correct information. And if the company changes the operating equipment, it is up to them to send the appropriate change message.
Is this another case of catering for the lowest common denominator and not giving a swift kick up the ar$e to those who don't do the right thing?
In my brief 12 years in ATC, I can count on one hand the number of times that the operating equipment have changed and we have not been notified before the aircraft moves. Even then, the crew have a copy of the submitted flightplan and have always cross-checked and alerted us if there has been a change.
As for descending on the glidepath, don't get me started on that lowest common denominator, just-in-case crap.
Cheers,
NFR.
