Which of the following is a key factor pilots should check before departure?

Before departure, it is crucial for pilots to check runway clearance and weather conditions. These factors significantly impact the safety and efficiency of a flight.

Runway clearance ensures that the aircraft can take off or land safely without any obstacles or hazards on the runway. Pilots must confirm that the runway is clear and meets the necessary requirements to accommodate their aircraft, such as length and surface condition.

Weather conditions are equally important to assess, as they can affect visibility, wind direction, and overall flight safety. Knowledge of current and forecasted weather conditions helps pilots make informed decisions about whether to proceed with the flight or adjust their plans, including potential delays or rerouting.

Checking runway clearance and weather conditions is a standard part of the pre-flight checklist and is critical for ensuring a safe and successful flight operation.
