FAA Aircraft Dispatcher Practice Exam

Which of the following information is NOT typically displayed in a Radar summary chart?

1. Areas of precipitation

2. Wind direction

3. Movement of precipitation cells

4. Weather watches

The correct answer is: Wind direction

A radar summary chart provides a visual representation of various weather elements that can assist in flight planning and operations. Typically, it includes areas of precipitation, showing where rain, snow, or other forms of precipitation are occurring. It also indicates the movement of precipitation cells, helping meteorologists and dispatchers understand how weather systems are changing over time. In addition to these elements, the chart may include alerts or notifications about severe weather conditions, such as weather watches, which inform users of potential hazardous weather that could impact flight safety. Wind direction, however, is not usually included on a radar summary chart. While understanding wind conditions is crucial for pilots and dispatchers, wind vectors are typically found in other types of weather charts, such as surface analysis charts or wind shear maps. These charts are specifically designed to depict wind patterns and conditions at various altitudes, making them more suitable for that information compared to a radar summary chart focused on precipitation and severe weather alerts.
