An improved system and method are disclosed for eliminating pilot confusion in visualizing multiple categories of data, such as, for example, weather data and terrain data, simultaneously on an integrated, multi-color display. For example, an aircraft display system is disclosed that includes a processing unit, a terrain database, a weather data source, a visual display for displaying multi-color weather data and terrain data, and a control device for controlling the duration of the weather data being shown on the visual display. As an aircraft proceeds along a flight path, the processing unit retrieves and / or receives weather data from the weather data source and terrain data from the terrain database. The processing unit provides color renderings of the terrain data to the visual display. The processing unit determines a time duration for the weather data from a setting of the control device (e.g., set by a pilot), and provides color renderings of the weather data to the visual display for the selected time duration. For example, the weather data sweep on the display can become narrower or wider depending on the time duration selected. Also, for example, the trailing edge of the weather data sweep can become more transparent and / or opaque as the sweep becomes narrower. Thus, the pilot is allowed to control the length of time that the weather data is being displayed, which reduces and / or eliminates confusion in visualizing the terrain data and weather data being displayed simultaneously on the integrated, multi-color display.
