How does weather impact flight planning and operations?

Weather plays a critical role in flight planning and operations, directly influencing various aspects such as route selection, fuel calculations, and overall safety considerations.

When planning a flight, pilots and flight planners must account for current and forecasted weather conditions, including wind speed and direction, precipitation, and visibility. For instance, strong headwinds may require additional fuel to reach the destination, while severe thunderstorms may necessitate the alteration of routes to ensure passenger and crew safety. Furthermore, adverse weather conditions can affect airport operations, including takeoff and landing procedures, potentially leading to delays or diversions.

Incorporating weather information into flight planning is essential to ensure efficient and safe operations, which highlights the importance of option B being the correct answer.
