Pierre,
Hows life in your ever-changing uniform?
Don't know about Swanwick i.e. LACC, but at TC (civvy side) we still ident to activate certain flight plans - not all departures have the facility of doing this automatically.
That will continue to be the case when we move to Swanwick in Nov (or at a later date tbc!), using the same equipment near enough, but with a new fangled comms set up (if it works)
