A display system for a rotorcraft comprising: a display; an avionics system; a synthetic vision system; and a processor coupled to the display, avionics system, and synthetic vision system, the processor configured to: ascertain flight parameters of the rotorcraft from the avionics system, the flight parameters including a heading; ascertain a view from the rotorcraft from the synthetic vision system, the view comprising a horizontal span; provide commands to the display to display the view; provide commands to the display to display a compass including a first index indicating the heading, the compass including a heading scale; and provide commands to the display to display an arc contiguous or adjacent to a portion of the heading scale of the compass, the arc having a span that represents the horizontal span of the synthetic vision system view being displayed; provide commands to the display such that the arc is moved in relation to the heading scale as a heading of the rotorcraft changes with respect to a flight path of the rotorcraft; and provide commands to the display to display a course pointer within the compass indicating the desired ground track, characterised in that the arc has a transparency which is increased in intensity based on the amount of alignment between the ground track and the heading. a display; an avionics system; a synthetic vision system; and a processor coupled to the display, avionics system, and synthetic vision system, the processor configured to: ascertain flight parameters of the rotorcraft from the avionics system, the flight parameters including a heading; ascertain a view from the rotorcraft from the synthetic vision system, the view comprising a horizontal span; provide commands to the display to display the view; provide commands to the display to display a compass including a first index indicating the heading, the compass including a heading scale; and provide commands to the display to display an arc contiguous or adjacent to a portion of the heading scale of the compass, the arc having a span that represents the horizontal span of the synthetic vision system view being displayed; provide commands to the display such that the arc is moved in relation to the heading scale as a heading of the rotorcraft changes with respect to a flight path of the rotorcraft; and provide commands to the display to display a course pointer within the compass indicating the desired ground track, characterised in that the arc has a transparency which is increased in intensity based on the amount of alignment between the ground track and the heading. ascertain flight parameters of the rotorcraft from the avionics system, the flight parameters including a heading; ascertain a view from the rotorcraft from the synthetic vision system, the view comprising a horizontal span; provide commands to the display to display the view; provide commands to the display to display a compass including a first index indicating the heading, the compass including a heading scale; and provide commands to the display to display an arc contiguous or adjacent to a portion of the heading scale of the compass, the arc having a span that represents the horizontal span of the synthetic vision system view being displayed; provide commands to the display such that the arc is moved in relation to the heading scale as a heading of the rotorcraft changes with respect to a flight path of the rotorcraft; and provide commands to the display to display a course pointer within the compass indicating the desired ground track, characterised in that the arc has a transparency which is increased in intensity based on the amount of alignment between the ground track and the heading.
