FoxDonut77 Posted May 10, 2010 Posted May 10, 2010 (edited) I'm not sure I've figured out the HDI in the Su25. Shouldn't the compasse bearing indicated by the upper center notch indicate the actual geographic compasse bearing? I'm usually finding myself going due north whereas the HDI indicates a bearing that's several tens of degress off, am I reading this thing wrong or something? 37 views and no replies, am I that diffuse or is simply that nobody knows?
