What type of weather phenomena would be included in a TAF?

A Terminal Aerodrome Forecast (TAF) is designed to provide essential weather information for aviation operations at airports and aerodromes. It focuses on significant meteorological phenomena that may affect flight operations over a designated period, typically a 24 to 30-hour forecast period.

Fog, hail, and snow are all important weather phenomena that can impact visibility, aircraft performance, and safety. Fog can reduce visibility to critical levels, making it a significant focus for TAFs, particularly at airports where operations depend heavily on visual flight rules.

Hail, while typically associated with thunderstorms, can damage aircraft and impact ground operations. Thus, its presence in a TAF is relevant when there is a risk of thunderstorms.

Snow can have various effects, including runway conditions and aircraft de-icing procedures, making it a crucial element within TAFs, especially in winter months or areas prone to snowfall.

Including all these meteorological phenomena in a TAF reflects its comprehensive nature, aimed at ensuring pilots and air traffic controllers receive relevant forecasts that help them make informed decisions regarding flight safety and operational planning. Therefore, encompassing fog, hail, and snow under the umbrella of significant weather phenomena deemed essential for aviation makes the selection of “all of the above” the
