How often is the information in D-ATIS updated?

The information in D-ATIS (Digital Automatic Terminal Information Service) is updated continuously as needed to provide the most current flight and weather information to pilots. This system is designed to ensure that the data reflects real-time conditions, including changing weather, runway availability, and other operational details that are crucial for flight safety and planning.

This capability allows pilots to receive immediate updates about factors that might affect their flight, such as changes in weather patterns or adjustments to airport operations. The continuous updating process ensures that pilots are receiving information that is as fresh and accurate as possible, which is essential for maintaining operational efficiency and safety in air travel.

The other options suggest less frequent updating intervals which would not adequately address the dynamic nature of aviation operations where conditions can change rapidly and pilots require up-to-date information for effective decision-making.
