An avionic display system, comprising: a display device on which an avionic display (34, 36, 37) is generated; and a controller architecture operably coupled to the display device, the controller architecture configured to: determine (48, 50) when there arises a possibility of an overpressure event occurring in a future timeframe due to constructive interference between pressure waves forecast to occur during supersonic aircraft flight; and when determining that there exists a possibility of an overpressure event occurring in the future timeframe due to constructive interference between pressure waves, provide a visual indication (64, 66, 72, 112, 114, 116, 118, 120, 124) of the potential occurrence of the overpressure event on the avionic display (34, 36, 37),wherein the controller architecture is configured to determine (48, 50) when there exists a possibility of an overpressure event occurring in a future timeframe due to constructive interference between pressure waves by: monitoring for predicted collisions between pressure waves forecast to occur during supersonic aircraft; when pressure waves are predicted to collide, estimating a maximum combined amplitude potentially resulting from constructive interference between the colliding pressure waves; and determining that there exists a possibility of an overpressure event occurring in the future timeframe due to constructive interference between the colliding pressure waves when the maximum combined amplitude exceeds a boom tolerance threshold, characterized in that the boom tolerance threshold has a variable value that is actively adjusted, by the controller architecture, based on one or more parameters pertaining to a pressure wave collision. a display device on which an avionic display (34, 36, 37) is generated; and a controller architecture operably coupled to the display device, the controller architecture configured to: determine (48, 50) when there arises a possibility of an overpressure event occurring in a future timeframe due to constructive interference between pressure waves forecast to occur during supersonic aircraft flight; and when determining that there exists a possibility of an overpressure event occurring in the future timeframe due to constructive interference between pressure waves, provide a visual indication (64, 66, 72, 112, 114, 116, 118, 120, 124) of the potential occurrence of the overpressure event on the avionic display (34, 36, 37),wherein the controller architecture is configured to determine (48, 50) when there exists a possibility of an overpressure event occurring in a future timeframe due to constructive interference between pressure waves by: monitoring for predicted collisions between pressure waves forecast to occur during supersonic aircraft; when pressure waves are predicted to collide, estimating a maximum combined amplitude potentially resulting from constructive interference between the colliding pressure waves; and determining that there exists a possibility of an overpressure event occurring in the future timeframe due to constructive interference between the colliding pressure waves when the maximum combined amplitude exceeds a boom tolerance threshold, characterized in that the boom tolerance threshold has a variable value that is actively adjusted, by the controller architecture, based on one or more parameters pertaining to a pressure wave collision. monitoring for predicted collisions between pressure waves forecast to occur during supersonic aircraft; when pressure waves are predicted to collide, estimating a maximum combined amplitude potentially resulting from constructive interference between the colliding pressure waves; and determining that there exists a possibility of an overpressure event occurring in the future timeframe due to constructive interference between the colliding pressure waves when the maximum combined amplitude exceeds a boom tolerance threshold, characterized in that the boom tolerance threshold has a variable value that is actively adjusted, by the controller architecture, based on one or more parameters pertaining to a pressure wave collision.
