Seems to me that the value should be as it is since it is a measurement downstream of the heat exchanger where the fuel temperature is controlled.

But this FT value remains constant and not change during all phases of flight.

Hi Stanislav, did you tested the cold and dark situation and check the fuel temp gauge right after switching the batteries on ? At this stage have a look on the gauge. On my system it shows a lower temp than after switchting all on. So may be its real simulated and the heating system will hold the temp all the time on the same level ? Its my conclusion on this.BestSteffen
