A flight deck display system and related operating methods for an aircraft are provided. The system includes a processor architecture and a display element coupled to the processor architecture. The processor architecture is configured to receive real-time aircraft data and terrain data for the aircraft and, based upon the real-time aircraft data and the terrain data, generate image rendering display commands. The display element receives the image rendering display commands and, in response thereto, renders a primary flight display that includes a conformal view of terrain corresponding to a flight deck viewpoint. The primary flight display also includes a conformal terrain avoidance guidance (TAG) element on the view of terrain. The TAG element includes visual indicia of a desired navigation path that is intended to avoid terrain that obstructs a current flight path of the aircraft.
