It´s not just a DLC. It´s a PMDG! One has joy and interesting things to read and study for weeks when buying a PMDG 
And so it is true, an iniBuild Airbus is really coming to Flight Sim 20?! EPIC! I hope that this window showing the animated turbine with all the technical data will be available too.
(I would even pay 20$ more added to the price just to get this detailed engine simulation! This is beyond AWESOME it´s fully animated and shows endless details of every engine section.)
