Unless explicitly indicated otherwise, all traffic patterns at non-towered airports are to the left. The direction of the pattern may be indicated by a traffic pattern indicator in the aerodrome's signal square. In the United States, the Code of Federal Regulations CFR 91.126 a. (2) requires helicopters to avoid the flow of fixed wing aircraft. [2]

This SVG diagram contains embedded raster graphics. Such images are liable to produce inferior results when scaled to different sizes (as well as possibly being very inefficient in file size). If appropriate to do so, they should be replaced with images created using vector graphics .
In aviation, a traffic pattern indicator is an L-shaped device which show the airfield traffic pattern to the in-flight aircraft over an aerodrome. [2] The short arm of the "L" represents the base leg, and the long arm the final approach. [3] If no segmented circle is installed, traffic pattern indicators may be installed on or near runway ends ...
The core of a network dataset is a vector layer of polylines representing the paths of travel, either precise geographic routes or schematic diagrams, known as edges. In addition, information is needed on the network topology, representing the connections between the lines, thus enabling the transport from one line to another to be modeled.
Flight Traffic Mapping uses animation to depict flight traffic. The mapping of flights [ 1 ] in real-time is based on a sophisticated air traffic control system that was developed for North America. The air traffic control system is a complex combination of electronics and people that helps guide planes from departure to destination.
A continuous flow intersection (CFI), also called a crossover displaced left-turn (XDL or DLT), is an alternative design for an at-grade road junction. Vehicles attempting to turn across the opposing direction of traffic (left in right-hand drive jurisdictions; right in left-hand drive jurisdictions) cross before they enter the intersection. No ...
Traffic simulation or the simulation of transportation systems is the mathematical modeling of transportation systems (e.g., freeway junctions, arterial routes, roundabouts, downtown grid systems, etc.) through the application of computer software to better help plan, design, and operate transportation systems.
