When must a pilot perform a weather briefing?

A pilot must perform a weather briefing prior to each flight to ensure they have the most current and relevant information regarding weather conditions along their route. This briefing is essential for safe flight planning and decision-making, as it provides critical data such as winds, visibility, cloud cover, and any potential hazards like thunderstorms or icing that may affect the flight. By conducting the briefing beforehand, a pilot can assess whether conditions are suitable for the planned flight and can adjust their plans accordingly if necessary.

The importance of a thorough weather briefing cannot be understated, as weather conditions can change rapidly and significantly impact flight safety. This proactive approach helps to ensure that pilots are well-informed and prepared to handle the actual conditions they may encounter, ultimately enhancing flight safety.
