What does a segmented circle's extensions point towards?

A segmented circle is a visual signaling tool used at airports to convey important information to pilots, particularly in non-towered airports or in visual flight rules (VFR) conditions. The extensions of a segmented circle, often referred to as "arms," are designed to point towards the runway in use. This means that their orientation directly correlates with the direction pilots should be approaching and departing from when they are using the airfield.

By pointing towards the center of the circle, the extensions help pilots quickly identify which runway or landing pattern they need to align with, based on wind direction or traffic patterns. This visual cue is crucial for effective communication in busy or uncontrolled airspace, allowing pilots to make informed decisions and maintain safe operations.

In contrast, options like the nearest airport terminal, the aircraft maintenance facility, or the fuel storage area do not provide relevant information for runway orientation and are not the main purpose of the segmented circle's design. The focus of the segmented circle is primarily on aiding pilot navigation and ensuring safety around the airport.
