I have a question about the HSI in the Piper Seneca. There is a discrepancy between the magnetic compass and the HSI, equal to the magnetic variation. So, the HSI seems to be displaying true heading. However, everything I read about HSI's says that it should display magnetic heading. Since the HSI is a gyro device, it needs to be adjusted to agree with the magnetic compass prior to flight, but I cannot find a way of doing that.
Should the HSI be displaying magnetic or true heading? If magnetic, how can it be adjusted to agree with the magnetic compass?
