FSLabs Updates the Community on Prepar3D v4 Changes!

Today, FSLabs has provided the release notes for the updated version of their Airbus A320 for Prepar3D v4.

From the phrasing used on their forum post, it sounds like the changes detailed are only going to be released for the new platform, at least initially – the FSX/FSX:SE/P3d 1-3 versions are referred to as the ‘older products’.

The list of updates is truly extensive, and includes considerable changes – if not complete overhauls – to/of all of the following elements:

  • Security protection
  • External model
  • Virtual Cockpit
  • Sounds
  • FMGC
  • ATSU
  • ACSC
  • ECB
  • FWC
  • SDAC
  • FAC
  • ELAC
  • MCDU
  • PFD
  • E/WD
  • ADIRUs
  • Brake logic
  • Failures
  • Keyboard usage
  • Tiller
  • Visual effects
  • Many other small bug fixes/improvements too small to note!

For the full list of improvements and updates, please see below.  For more information, you can see the post here and always keep an eye on FSLabs’ website and Facebook for more updates.

With this changelog posted, I have to think that the release for P3Dv4 is coming soon – good things come to those who wait, patience is a virtue, and all that!
