The short leg of each L is the traffic pattern indicator and represents the base leg. To determine the correct traffic pattern, just imagine you are flying a base leg for Runway 36 on the short part of the L at the bottom of the figure.
What do the L shaped symbols on a runway mean?
This can be found by examining the “L” shaped symbols around the segmented circle. The long leg of each L is the landing runway indicator and represents the approach end, or final leg, to a runway. The short leg of each L is the traffic pattern indicator and represents the base leg.
What are the components of a segmented circle in aviation?
Each segmented circle consists of three components: the landing runway indicators, the traffic pattern indicators, and the wind cone. Each gives pilots a different piece of information to determine the correct traffic pattern to fly and the correct runway to land on.

How do you enter left traffic patterns?
If departing the traffic pattern, the pilot should continue straight out or exit with a 45° turn (to the left when in a left-hand traffic pattern; to the right when in a right-hand traffic pattern) beyond the departure end of the runway after reaching the traffic pattern altitude.
What is a segmented circle in aviation?
A segmented circle is a visual indicator that provides traffic pattern information to pilots at airports without a control tower. Each segmented circle consists of three components: the landing runway indicators, the traffic pattern indicators, and the wind cone.
What is the purpose of the segmented circle?
The segmented circle performs two functions; it aids the pilot in locating obscure airports and it provides a centralized location for such indicators and signal devices as may be required on a particular airport. Install the circle in a position affording maximum visibility to pilots in the air and on the ground.
What is a tetrahedron in aviation?
A large, triangular-shaped, kite-like object installed near the runway. Tetrahedrons are mounted on a pivot and are free to swing with the wind to show the pilot the direction of the wind as an aid in takeoffs and landings.
How can you determine if another aircraft is on a collision course?
How can you determine if another aircraft is on a collision course with your aircraft? The other aircraft will always appear to get larger and closer at a rapid rate. There will be no apparent relative motion between your aircraft and the other aircraft. The nose of each aircraft is pointed at the same point in space.
What does traffic pattern mean?
Princeton’s WordNet. traffic pattern, approach pattern, pattern (noun) the path that is prescribed for an airplane that is preparing to land at an airport. “the traffic patterns around O’Hare are very crowded”; “they stayed in the pattern until the fog lifted”

Where Are Wind Direction Indicators Located?
A wind cone, windsock, tetrahedron, and landing tee are all examples of wind direction indicators. These wind indicators are typically situated near the runway in a central area and might be in the middle of a segmented circle that indicates the traffic pattern direction if it is not the standard left-hand pattern.
Types of Wind Direction Indicators
1. Wind Socks Windsock displays wind direction and speed as the wind travels through the bigger aperture to its smaller end. There is a calm wind if the windsock is hanging limp. The higher the indicated wind speed, the more straight out the windsock is extended.
How Are Segmented Circles Related to Wind Indicators?
A segmented circle is used at some airports to provide pilots with information about wind and traffic pattern procedures. To form a segmented circle, a wind direction indicator, such as a tetrahedron, is surrounded by traffic pattern indicators.
How to Install a Wind Direction Indicator
As stated earlier, a windsock is an example of a wind direction indicator. While there are other wind indicators, we are going to discuss the installation of a windsock. Let’s begin!
How to Read a Wind Direction Indicator
1. Reading a Wind Cones According to FAA specifications, when the wind speed reaches three knots (3.5 mph), windsocks must orient themselves to point in the direction the wind going. In other words, if the small pointy end of the windsock is extending to the northeast, the wind is coming from the southwest.
How to Approximate Wind Speed from a Wind Cone
When the wind speed reaches three knots (3.5 mph), windsocks are made to orient themselves against the wind. Only the first segment of the windsock will be extended at that speed. This simply means that if the windsock is extending to the northeast, the wind is coming from the southwest.
Wind Cone Videos
This video provides an overview of reading both wind cones and tetrahedrons and also covers segmented circles and traffic patterns.
What Are Circles?
According to the Oxford dictionary, a circle is a plane figure, round in shape whose boundary, also known as a circumference, is equidistant from the center. As Pythagoras, the ancient Greek philosopher, and mathematician, puts it, circles are the most creative form.
What Circles Symbolize
Being one of the oldest geometric symbols, the circle has earned itself a name and respect in both education and culture. It’s a universal sign, with almost all cultures revering it as a sacred symbol. The circle represents limitless things, among them eternity, unity, monotheism, infinity, and wholeness.
Symbols Based on Circles
With the powerful symbolism associated with the circle, it’s no wonder there exist numerous symbols and artifacts resembling circles and shapes. Some of these symbols include:
Wrapping Up
The circle is such a prominent symbol in nature, culture, and life, so much so that its symbolism is inexhaustible. From what we have seen, the universe itself is circular, and life is powered from its core.
How to determine the location of a point on the planet?
The location of every point on the planet can be determined by latitude and longitude coordinates as defined by an imaginary grid pattern. To easily remember the difference between the latitude and longitude, we must first define the location of the equator and the prime meridian.
What is a quadrant on a sectional chart?
A quadrant is an area defined by a boundary within 30 minutes latitude and 30 minutes longitude.
What is class G?
Class G, or uncontrolled airspace, is the least restrictive of all airspace types. Since it’s not under the jurisdiction of any ATC facility, there is no need to secure any authorization to fly in Class G airspace. This type of airspace is not explicitly marked in sectional charts.
Why do we need sectional charts?
Sectional charts are an invaluable tool for situational awareness and flight planning. Whether you’re flying professionally or for fun, checking out a sectional chart must be part of your pre-flight procedures if you don’t want to end up hitting a flight restriction when you’re already out on the field.
Where is the prime meridian?
The prime meridian is a line that runs from the North to South poles and passes through Greenwich, New England. This also acts as the “zero longitude” and is the basis for the measurement of all other longitudes, or lines that run North to South. Lying perpendicular to the prime meridian is the equator.
Is sectional chart confusing?
If you feel the same way, don’t worry – sectional charts are still somewhat confusing even for experienced drone pilots. With a bit of patience, you will eventually learn to make the most out of all the information that a sectional chart offers.
