The Radar summary chart specifically displays observed weather conditions in real-time. It provides a visual representation of precipitation, including its intensity and movement, which is crucial for pilots and dispatchers in flight planning and management. This chart uses radar technology to detect and depict various weather phenomena such as rain, thunderstorms, and other significant weather systems currently affecting an area.

Future weather forecasts are not included in the radar summary, as this chart is designed to show live conditions rather than predictions. Historical weather trends are also outside the scope of the radar chart, as it focuses solely on what is happening at the moment. Air pressure readings, while important in meteorology and aviation, are measured separately and represented differently, such as in surface weather charts or METARs, not in a radar summary chart. Therefore, the radar summary chart provides essential real-time data that aids in ensuring safe and efficient flight operations.
