Which option correctly pairs wind indicators?

• A. Windsock/Wind Cone and Anemometer
• B. Windsock/Wind Cone and Barometer
• C. Windsock/Wind Cone and Tetrahedron/Wind T
• D. Windsock/Wind Cone and Compass

Answer: (C)

The main idea is that wind indicators are devices used to show the wind’s direction (and sometimes speed) at a location. A windsock or wind cone is the classic visual tool for wind direction at an airfield; it points toward the direction from which the wind is coming and gives a rough sense of wind speed by how extended it is. A tetrahedron, known as Wind T, is another wind direction indicator that rotates with the wind and shows direction when it points toward the airflow. Pairing two wind direction indicators reinforces the concept of observing wind direction from different types of indicators. Other options mix a wind direction indicator with tools that measure something else. Anemometers measure wind speed, not direction, while barometers measure atmospheric pressure. A compass provides navigational heading, not wind information. Since the goal is to pair wind indicators, two devices that indicate wind direction make the best match.
