1. An aircraft computer apparatus comprising:
a display device; and
at least one processor in data communication with a memory storing processor executable code for configuring the at least one processor to:
render a flight path on a navigational display;
render an altitude and speed indicator on a vertical situational display;
compute a real-time sonic boom footprint;
render the real-time sonic boom footprint to the navigational display;
compute a predicted sonic boom footprint;
render the predicted sonic boom footprint to the navigational display;
identify one or more regions along the flight path where a pressure difference or decibel level associated with at least one of the real-time sonic boom footprint or the predicted sonic boom footprint violate a predefined limit;
identify the one or more regions on the vertical situational display;
iteratively modify an altitude parameter and a speed associated with one of the one or more regions and recompute the predicted sonic boom footprint to determine a minimum altitude change to resolve the violation, beginning with an altitude change corresponding to a proportional difference between the predicted pressure difference and the predefined limit;
receive a flight corridor;
beginning from edges of the flight corridor, iteratively recompute the predicted sonic boom footprint to determine a minimum lateral movement to resolve the violation;
iteratively recompute the predicted sonic boom footprint based on the minimum altitude change and minimum lateral movement to identify one or more combinations of altitude change and lateral movement to resolve the violation;
render a plurality of computed interval markers in the real-time sonic boom footprint, spaced according to the speed;
render a plurality of predicted interval markers in the predicted sonic boom footprint, spaced according to the speed;
compile a set of related lateral movements, altitudes, and speeds that resolve the violation; and
display the set of related lateral movements, altitudes, and speeds on the vertical situational display,
wherein:
each computed interval marker is rendered to provide a visual indication if the computed interval marked corresponds to a resolvable violation or an unresolvable violation; and
each predicted interval marker is rendered to provide a visual indication if the predicted interval marked corresponds to a resolvable violation or an unresolvable violation.
