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]
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 charts are published "in accordance with Interagency Air Cartographic Committee specifications and agreements, approved by the Department of Defense and the Federal Aviation Administration". The legend of an aeronautical chart lists many of the symbols, colors and codes used to convey information to the map reader.
An aeronautical chart is a map designed to assist in the navigation of aircraft, much as nautical charts do for watercraft, or a roadmap does for drivers. Using these charts and other tools, pilots are able to determine their position, safe altitude, best route to a destination, navigation aids along the way, alternative landing areas in case of an in-flight emergency, and other useful ...
The sectionals are complemented by terminal area charts (TACs) at 1:250,000 scale for the areas around major U.S. airports, and until 2016 by World Aeronautical Charts (WACs) at a scale of 1:1,000,000 for pilots of slower aircraft and aircraft at high altitude. [1] Since February 2021, the charts have been updated on a 56-day publication cycle. [2]

Air traffic control may assist in navigation by assigning pilots specific headings ("radar vectors"). The majority of IFR navigation is given by ground- and satellite-based systems, while radar vectors are usually reserved by ATC for sequencing aircraft for a busy approach or transitioning aircraft from takeoff to cruise, among other things.
