What must be considered when authorizing runway use in the presence of a tailwind?

• A. Runway surface conditions
• B. Aircraft type
• C. Wind direction and velocity
• D. Visibility

Answer: (C)

When authorizing runway use in the presence of a tailwind, it is crucial to consider wind direction and velocity because tailwinds can significantly affect an aircraft's takeoff and landing performance. A tailwind increases the takeoff distance required and can extend the landing distance, reducing the margin for safety. Understanding the specific wind conditions helps ensure that pilots can safely operate their aircraft, especially during critical phases of flight. While factors like runway surface conditions, aircraft type, and visibility are important safety considerations, they do not specifically address the distinct challenges posed by tailwinds. The impact of wind direction and velocity directly correlates with how aircraft performance is affected, making it the focal point for effective runway authorization in such conditions.
