From the developer:
FSTramp for FSX is a plug-in that can be activated with Ctrl+F12. Pressing this Hotkey makes Flight Simulator change its face to become FSTramp. At the same time all Flight Simulator functions continue normally. In the alternative display mode FSTramp is a separate window, that can be positioned freely anywhere.
