Hi guys,
now that I am also over 100 hours into A2A's C182, I thought I look for an alternative for X-Plane. Actually, the thing that most interests me is a way to keep the status of the airplane's equipment "static" from flight to flight with ageing while simulator is off.
And shockingly, there is something for X-Plane that resembles A2A

. It is called Real Expansion Pack for Cessna Centurion. You have a hangar, can change and repair parts, plane state is loaded from the last flight's state, engine temperature is consistent with how long the plane stayed on the ground between the flights, etc. You even get the oxygen system simulated for high cruise flights.
To be able to use this, you do have to own the CT210M Centurion II HD Series from Carenado prior and then get the Reality Expansion from Simcoders. What you don't get is the wear and tear of a plane sitting on the ground for long periods (the engine just cools down) of time as with the A2A's. Also, there is no walk around with worn hinges on ailerons and no impurities in the fuel. But the very good thing is that you do get an engine simulation in X-Plane.
Having said this, there are other X-Plane add-ons that employ a form of persistent state but not to the detail of Simcoders': all Flight Factor add-ons keep track of the landing rates and taxes you on hard landing the next flight.
Cheers.
