Avionic display systems and methods are provided for generating avionic displays, which include symbology and other graphics pertaining to forecast overpressure events, which are forecast to occur during supersonic aircraft flight. In various embodiments, the avionic display system includes a display device on which an avionic display is produced. A controller architecture is operably coupled to the display device. Storage media contains computer-readable code or instructions that, when executed by the controller architecture, cause the avionic display system to determine whether an overpressure event is forecast to occur due to the predicted future occurrence of a sonic boom, which has a magnitude exceeding a boom tolerance threshold. When the controller architecture determines that an overpressure event is forecast to occur, the avionic display system further generates symbology on the avionic display indicative of or visually signifying the forecast overpressure event.
