How frequently is a wind shear report updated?

Wind shear reports are updated frequently to ensure that pilots have the most current information available for safe operation, especially during takeoff and landing phases where wind shear can pose significant hazards. The correct answer emphasizes that wind shear reports are updated every minute. This frequent updating allows for real-time tracking of changing atmospheric conditions, which is critical for maintaining operational safety and effective decision-making by flight crews.

In the context of aviation operations, particularly around airports, conditions can change rapidly; thus, timely updates reflect the latest observations. Other options, such as longer intervals for updates, would not adequately provide the level of situational awareness necessary for pilots to react to rapidly changing conditions.
