What type of information do TAFs contain?

TAFs, or Terminal Aerodrome Forecasts, provide essential information about expected weather conditions at specific airports over a set time frame, typically covering a 24 to 30-hour period. The primary purpose of TAFs is to help pilots and flight planners understand anticipated weather phenomena that could impact flight safety and operations.

These forecasts include details on significant weather events such as changes in wind direction and speed, visibility issues, precipitation, and cloud cover. By focusing on forecasts for significant weather conditions, TAFs serve as a critical tool for pre-flight planning and in-flight decision-making. Understanding the forecast allows pilots to prepare for conditions that might affect takeoff, landing, or en route flying.

The other options, while related to weather information, do not accurately describe the nature of TAFs. For instance, current weather observations provide real-time data, historical weather data reflects past conditions, and reports on local air traffic pertain to the flow and status of aircraft rather than weather forecasting. Therefore, the content of TAFs specifically emphasizes predictions of future weather that can significantly impact aviation operations.
