IvanK Posted February 11 Posted February 11 (edited) With NAV COMP selected and following steering to the selected TGT/waypoint the HSI heading marker can be set to any desired heading by the pilot. This is I believe is a bug. According to the F4E manuals (Page 1-48 Figure 1-18 and the table Page 1-45 Figure 1-15) the heading bug is controlled by the Nav system and set to the wind drift corrected heading to achieve the direct track to the selected Waypoint. It cannot be set by the pilot. TRK attached. F4Hdgbug.trk Edited February 11 by IvanK 2
