    AviTab

    AviTab

    X-Plane plugin that displays a tablet to aid VR usage

    ...It displays a tablet-like computer with a few apps in the cockpit. It is mainly used for flying in virtual reality. When flying in a simulator, one often needs to look up details in PDF charts, plane manuals, checklists or other documents. Using a PDF reader breaks the immersion because the virtual aviator either has to take off of their HMD or use other tools that can move windows into VR. AviTab tries to solve this problem by offering a PDF reader inside a native plugin for X-Plane. Using a plugin also opens possibilities for more apps inside the tablet, for example, to display information about the plane status or aid in navigation. ...
