When the wind is less than 5 knots, which runway usage is recommended?

1. Crosswind Runway

2. Calm Wind Runway

3. Overflow Runway

4. Remote Runway

The correct answer is: Calm Wind Runway

When the wind is less than 5 knots, the recommended usage is the Calm Wind Runway. This choice is preferred because light and variable winds do not create significant aerodynamic forces on the aircraft, making it less critical to align with the prevailing wind direction for takeoffs and landings. In such conditions, the Calm Wind Runway generally refers to the runway that is most suitable for use when wind conditions are negligible. This enhances safety and efficiency as aircraft can operate more freely without concern for crosswinds affecting their performance during critical phases of flight. Other runway options, such as the Crosswind Runway, are more applicable in situations where winds are stronger and present a challenge for aircraft during operations. Overflow and Remote Runways do not specifically address the need for calm wind conditions and are typically used for other operational purposes unrelated to low wind situations. Thus, the Calm Wind Runway is the logical and safest choice when wind speeds are minimal.
