How does weather impact runway operations?

Weather significantly influences runway operations, particularly in terms of safety. Adverse weather conditions, such as heavy rain, snow, fog, or strong winds, can affect runway surface conditions and visibility, necessitating modifications to operational procedures. For instance, when visibility decreases below certain thresholds, or if snow and ice accumulate on the runway, air traffic control may implement changes to ensure safe landings and takeoffs. This could involve switching to runways that are better suited for current weather conditions or altering approach paths to mitigate risks.

Runway changes for safety purposes are crucial in preventing accidents and ensuring that aircraft operate within safe parameters. Given that other factors can also be influenced by weather, such as gate assignments or aircraft type restrictions, the primary focus during adverse conditions remains aimed at operational safety, which underscores the importance of adjusting runway usage accordingly.
