FAA Aircraft Dispatcher Practice Exam

What critical information is included in TAFs?

1. Only temperature and dew point

2. Visibility and forecasted precipitation

3. Current temperature

4. Time of sunset and sunrise

The correct answer is: Visibility and forecasted precipitation

TAFs, or Terminal Aerodrome Forecasts, provide essential weather information specifically focused on the forecast conditions at an airport over a 24 or 30-hour period, depending on the TAF issuance. The critical information included in TAFs encompasses visibility, forecasted wind direction and speed, forecasted weather phenomena such as rain or snow, and significant changes in weather conditions expected during the forecast period. Visibility and forecasted precipitation are fundamental aspects since they directly impact flight operations, influencing decisions related to takeoff and landing safety. Understanding these elements allows dispatchers to assess the operational environment and plan accordingly, ensuring that all safety measures are considered in flight operations. The other options are limited in scope. For instance, temperature and dew point are important, but TAFs focus more comprehensively on visibility and precipitation rather than solely these aspects. Current temperature does not impact the TAF, as it is typically not part of the forecast for future conditions; TAFs project expected weather, not current readings. Lastly, the time of sunset and sunrise, while relevant to operations, is not part of TAF content. Therefore, the answer highlighting visibility and forecasted precipitation truly captures the essence of what TAFs provide.
