What action should pilots take to ensure safety when flying?

Assessing hazards beforehand is a fundamental safety measure for pilots because it allows them to identify potential risks and challenges that could impact the flight. This proactive approach enables pilots to prepare for various scenarios by reviewing weather conditions, air traffic, and any other factors that might pose a danger. By understanding the environment and any hazards present, pilots can make informed decisions and implement strategies to mitigate those risks, thus enhancing the overall safety of the flight.

In contrast, following flight plans strictly, while important, does not account for changing conditions that may arise, such as unexpected weather changes or air traffic control instructions. Similarly, flying with passengers is not inherently linked to safety; it is the pilot's responsibility to ensure safe operations regardless of passenger presence. Making assumptions based on experience can be dangerous as it might lead to complacency, preventing pilots from adequately assessing new or unexpected situations that could arise during flight.
