Tango Posted September 18, 2014 Posted September 18, 2014 Hi, HSI doesn't appear to behave correctly during start up and alignment. When pressing the button to align the system to the sensed magnetic heading, the course pointer moves but not the compass card, then when the course pointer reaches zero, the heading card then aligns and both rotate together. It depends upon the start position of the aircraft as to how apparent this behavior is.
