FAA Ground School Practice Test

What is the purpose of the segmented circle in aviation?

1. To show runway dimensions

2. To indicate traffic patterns

3. To measure flight distance

4. To determine altitude

The correct answer is: To indicate traffic patterns

The segmented circle serves a crucial role in aviation by indicating traffic patterns at airports, especially those without an operating control tower. It is a visual aid for pilots, helping them understand the flow of aircraft in the vicinity of the airport. The various segments of the circle represent specific traffic pattern indicators, such as the preferred runway in use and the direction of traffic relative to that runway, thereby promoting safety and efficiency in airport operations. While showing runway dimensions, measuring flight distances, or determining altitude are important aspects of aviation, they do not pertain to the primary function of the segmented circle. The circle itself directly relates to the management of air traffic around an airport, guiding pilots on how to approach and depart while maintaining proper separation from one another.
