A system for generating an alert to the presence of emission vapors for a low altitude in-flight aircraft, comprising: an obstacle database containing parameters of obstacles in proximity to the aircraft, where the obstacles are located in petrochemical industrial facilities; a terrain database containing parameters of terrain in proximity to the aircraft; a core synthetic vision processor in operable communication with the obstacle database and the terrain database, the core synthetic vision processor configured to create a graphic overlay of the terrain and the obstacles based on the parameters in the obstacle database and the terrain database; an imaging camera configured to create a thermal image of emission vapors detected in proximity to the aircraft, where the emission vapors comprise invisible vapors that are only detected by temperature data recorded by the camera and where the emission vapors are vented by the obstacles from the petrochemical industrial facilities; a combined vision processor in operable communication with the core synthetic vision processor and the imaging camera, the combined vision processor configured to combine the graphic overlay with the thermal image of the emission vapors to create a combined synthetic image; an exhaust threat calculator in operable communication with the combined vision processor and configured to analyze for the presence of emission vapors in proximity to the aircraft based on the combined synthetic image, current environmental conditions in proximity to the aircraft, and characteristics of the emission vapors; an alert system in operable communication with the exhaust threat calculator and configured to alert the aircraft to the presence of emission vapors detected by the emissions threat calculator; and an avoidance advisory system in operable communication with the exhaust threat calculator and configured to generate cues for the pilot of the aircraft with suggested maneuvers to avoid the emission vapors. an obstacle database containing parameters of obstacles in proximity to the aircraft, where the obstacles are located in petrochemical industrial facilities; a terrain database containing parameters of terrain in proximity to the aircraft; a core synthetic vision processor in operable communication with the obstacle database and the terrain database, the core synthetic vision processor configured to create a graphic overlay of the terrain and the obstacles based on the parameters in the obstacle database and the terrain database; an imaging camera configured to create a thermal image of emission vapors detected in proximity to the aircraft, where the emission vapors comprise invisible vapors that are only detected by temperature data recorded by the camera and where the emission vapors are vented by the obstacles from the petrochemical industrial facilities; a combined vision processor in operable communication with the core synthetic vision processor and the imaging camera, the combined vision processor configured to combine the graphic overlay with the thermal image of the emission vapors to create a combined synthetic image; an exhaust threat calculator in operable communication with the combined vision processor and configured to analyze for the presence of emission vapors in proximity to the aircraft based on the combined synthetic image, current environmental conditions in proximity to the aircraft, and characteristics of the emission vapors; an alert system in operable communication with the exhaust threat calculator and configured to alert the aircraft to the presence of emission vapors detected by the emissions threat calculator; and an avoidance advisory system in operable communication with the exhaust threat calculator and configured to generate cues for the pilot of the aircraft with suggested maneuvers to avoid the emission vapors.
