How can adverse weather conditions affect navigation?

Adverse weather conditions can significantly impact navigation by limiting visibility and altering flight planning. Low visibility due to fog, rain, snow, or other meteorological phenomena can hinder a pilot's ability to see the runway, other aircraft, and navigational aids. This reduction in visibility can lead to challenges in maintaining situational awareness and executing safe navigation.

Additionally, adverse weather conditions may necessitate changes in flight plans. For instance, strong winds may require deviations from the original route to ensure safety, and storms may preclude the ability to follow the planned course altogether. Pilots often rely on updated weather information to make real-time decisions about altitude, route, and even potential diversions to alternate airports. This adaptability in flight planning is crucial for ensuring safety and efficiency in navigation, which is directly impacted by weather conditions.
