    Prepar3D® Release 1.2 Highlights


    Reported by Doug Horton. The Prepar3D development staff is very responsive to adding and updating features, including suggestions from users, as well as updating the Learning Center and SDK for users and developers. In September 2011, Prepar3D® version 1.2 was launched. According to Lockheed Martin:


    “The (version 1.2) software release offers users full Windows 7 support in addition to several enhancements and new features. In this iteration, the multi-player experience is redesigned and improved, the multi-channel capability is extended, and rendering performance has been improved. Developers also have access to new resources, making training scenarios even easier to customize or create from scratch.”


    Prepar3D can be used by private pilots, commercial organizations, the military and academic users as a licensed software training program for virtually any scenario imaginable. Users can practice a mission or flight before it happens, to increase effectiveness during real-world operations. In a recent discussion, a senior executive of a chain of nine U.S. flight schools indicated that students learn faster and require fewer in-air training hours when they use computer flight simulator training in conjunction with flight school training.


    One of my favorite features of Prepar3D is that locations of undocked control panel, subpanels, and scenery windows on multiple monitors are saved with flight files and reappear when flights are reloaded.



    Prepar3D saves and loads assignments of undocked control panel and scenery views to multiple monitors in flight files.


    The complete list of updates and improvements in Prepar3D version 1.2 includes:


    Full Windows 7 Support

    • User interface redesign:
      • New interface and extended multiplayer experience

    Additional Flyable Aircraft Added to Standard Vehicle Set


    These aircraft were previously included as AI aircraft only, and they’re now flyable.

    • Beechcraft Baron 58 – in four liveries, plus G1000 model
    • Beechcraft King Air 350, in four liveries

    Below is an excerpt of the Select Vehicle menu showing the flyable Beechcraft airplanes, followed by two images of the airplanes.
