FSX/P3D. Aircraft updates can sometimes take long periods to work out and implement. But service packs should only typically take a few weeks to a month or so. In the case with the PMDG777, SP1 took nearly a year. But for the Aerosoft Airbus A318-19 Extended, the time frame is exactly where it should be. And this is no lite service pack either. They have addressed and fixed a number of issues I haven't even heard anyone complain about. Fixes that are too numerous to list here.
