The Turbine Gas Temperature (TGT) indicating system is a rapid response type system indicating the temperature of the hot gas stream entering the first stage of the LP turbine. All thermocouples are wired in parallel to provide an average temperature indication. TGT signals are connected to the respective indicator located int he flight station and to the engine fuel control amplifier for an over temperature signal.
This blog documents a project to build a functional Lockheed L-1011 cockpit replica using real flight hardware, NI labVIEW and the x-Plane software platform.
