Where do traffic pattern indicators extend from?

Traffic pattern indicators extend inward from the circle, providing crucial guidance for pilots approaching the airport. These indicators are designed to help pilots establish their position relative to the airport layout, enabling them to line up with the runway for landing safely. The traffic pattern itself typically consists of a rectangular area in which aircraft maneuver to ensure safe spacing and sequencing as they approach the runway.

The other options do not accurately represent the function or structure of traffic pattern indicators. The design does not extend outward from the runway, nor does it originate from the runway toward the terminal or from the departure gate. Instead, it is primarily about organizing aircraft movement within a defined area around the airport, making inward extension from the circle the most logical and accurate description of how traffic patterns are established and communicated to pilots.
