Flight Manual: Saab 35 Draken 5.0Updated: 2019-11-02


This is a complete package with model, textures, flight dynamics, sounds and effects. No other files are required except Lockheed Martin Prepar3D version 4.5 or later.

  1. Unzip the downloaded archive to a location on your computer.

  2. Double-click the installer executable and follow the on-screen instructions.

    The installer will try to locate the path to the Prepar3D v4 Add-ons folder in your user directory. If you made a custom install of Prepar3D you may have to enter the path manually.

  3. Click Next to accept the installation path, and Start in the following dialog box. The installer will now install all files in their correct locations.

  4. When you start Prepar3D after installing Draken, confirm that you wish to enable the Bookmark Simulations add-on.

First startup

The first time that you load Draken in Prepar3D, click on Shift-9 to bring up the options dialog if it is not already open. This panel is where you enable extra features such as the animated control stick and the engine and wing condensation fx.

If you load Draken after starting Prepar3D with the default scenario, the engine will be on but most of the sytems will still be off. For maximum realism you should start with a "cold and dark" aircraft. Close the fuel valve to shut down the engine, shut off the main electrical bus, and wait for the engine to spool down, then follow the procedure check lists to start up Draken.

Texture resolution

The exterior texture sheets are in 2048 pixel resolution. You need to set texture resolution in Prepar3D to High to enjoy the new textures.

To uninstall Draken, use the Programs and Features control panel in Windows. You can also simply delete the files in your Prepar3D v4 Add-ons folder. A configuration file for Draken is created in your user directory on first use. This file is not removed by the uninstaller.

Remember to back up any modifications that you wish to keep, such as modifications to the Aircraft.cfg file or textures that have been changed in the original folders. Files and folders that you may have added after installation (such as additional textures, sounds, effects, etc.) will not be affected by the uninstaller.
