A display system for use onboard an aircraft, the display system comprising: a sensor system, configured to detect external conditions; a source of aircraft state data; a display device configured to display images using display techniques including (i) synthetic vision, (ii) enhanced vision, (iii) combined vision, and (iv) compressed attitude; and a processor, communicatively coupled to the sensor system, the source of aircraft state data, and the display device, the processor configured to process the external conditions and aircraft state data to: dynamically determine a current roll angle, a current yaw angle, a current angle of attack, and a current flight path; generate an aircraft orientation cue, the aircraft orientation cue being a polygon defined by a top, a bottom, a first side and a second side, the top and bottom being parallel; orient the polygon reflective of the current roll angle; characterised in that the processor is further configured to: dynamically modify a vertical size of the polygon responsive to the current angle of attack; dynamically modify a length of the first side and a length of the second side responsive to the current yaw angle; and command the display device to dynamically display a representation of a current external environment, overlaid with (a) flight path symbology indicating the current flight path, and (b) the aircraft orientation cue at a current location of the aircraft. a sensor system, configured to detect external conditions; a source of aircraft state data; a display device configured to display images using display techniques including (i) synthetic vision, (ii) enhanced vision, (iii) combined vision, and (iv) compressed attitude; and a processor, communicatively coupled to the sensor system, the source of aircraft state data, and the display device, the processor configured to process the external conditions and aircraft state data to: dynamically determine a current roll angle, a current yaw angle, a current angle of attack, and a current flight path; generate an aircraft orientation cue, the aircraft orientation cue being a polygon defined by a top, a bottom, a first side and a second side, the top and bottom being parallel; orient the polygon reflective of the current roll angle; characterised in that the processor is further configured to: dynamically modify a vertical size of the polygon responsive to the current angle of attack; dynamically modify a length of the first side and a length of the second side responsive to the current yaw angle; and command the display device to dynamically display a representation of a current external environment, overlaid with (a) flight path symbology indicating the current flight path, and (b) the aircraft orientation cue at a current location of the aircraft. dynamically determine a current roll angle, a current yaw angle, a current angle of attack, and a current flight path; generate an aircraft orientation cue, the aircraft orientation cue being a polygon defined by a top, a bottom, a first side and a second side, the top and bottom being parallel; orient the polygon reflective of the current roll angle; dynamically modify a vertical size of the polygon responsive to the current angle of attack; dynamically modify a length of the first side and a length of the second side responsive to the current yaw angle; and command the display device to dynamically display a representation of a current external environment, overlaid with (a) flight path symbology indicating the current flight path, and (b) the aircraft orientation cue at a current location of the aircraft.
