If you experience a last-minute weather change before departure, what is your best course of action?

When faced with a last-minute weather change before departure, making adjustments and reassessing for safety is the most prudent course of action. This approach emphasizes the importance of assessing the current flight conditions and determining how they align with your pre-flight planning and the aircraft's capabilities. It is crucial to prioritize safety and ensure that the flight can be conducted within safe parameters.

In this situation, evaluating the weather changes allows you to make informed decisions regarding alternative routing, potential delays, or even postponing the flight entirely if conditions are not conducive to a safe operation. Such reassessment can include checking updated weather reports, discussing the changes with your crew, and considering any limitations your aircraft may have in adverse weather conditions.

The other choices do not reflect best practices for pilot decision-making. Continuing the flight without considering safety could lead to hazardous situations. Relying solely on the flight manual overlooks the dynamic nature of flying, where real-time adjustments and situational awareness are crucial. Additionally, waiting for passengers to decide puts the onus of safety on individuals who may not have the necessary training or knowledge to assess the situation appropriately. Thus, the most responsible action is to reassess based on the new weather information and adjust your plans accordingly for a safe flight.
