X T C is a hardware control panel interface for X-Plane. it is aimed at the training environment to simplify the simulator interface. XTC consists of a backlit 4 line display with a single selection knob on the left hand side which lets you select pairs of settings such as wind direction and speed and a dual knob on the right to let you set values for each. The left knob may be pushed to pause and the right one may be pushed to launch having for example selected a new heading. The Command buttons can instantly load a pre-saved flight. There are 4 push buttons directly below the display. The connection is USB.
A version for Lockheed Martin’s Prepar3D is under consideration.
