FAA-Terminal Area Chart Baltimore-Washington from 2011. Like the VFR sectional charts that they complement, terminal area charts depict topographic features and other information of interest to aviators flying visually, including major landmarks, terrain elevations, visual navigation routes, ground-based navigation aids, airports, rivers, cities, and airspace boundaries.
In 2006, the FAA issued a Notice of Proposed Rulemaking (NPRM) docket number 17005 concerning making the temporary rules permanent. Over 20,000 responses were received, the vast majority of them in opposition to making the temporary rules permanent. [13] There were two public hearings held by the FAA in the Washington D.C. area on the NPRM.
Following the terrorist attacks of September 11, 2001, the airspace around Washington DC underwent a number of changes designed to restrict flying around the city. In 2003, a temporary flight rules area was created and was named the Washington DC Air Defense Identification Zone.
Some prohibited airspace may be supplemented via NOTAMs. For example, Prohibited Area 40 (P-40) and Restricted Area 4009 (R4009) often have additional restricted airspace added via a NOTAM when the president of the United States visits Camp David in Maryland, while normally the airspace outside of P-40 and R4009 is not prohibited/restricted.
The United States has 22 Air Route Traffic Control Centers (ARTCC). [1] They are operated by and are part of the Federal Aviation Administration of the U.S. Department of Transportation . An ARTCC controls aircraft flying in a specified region of airspace, known as a flight information region (FIR), typically during the en route portion of flight.

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]
Between January 1, 2017 and December 31, 2017, Washington Center handled 2,554,410 aircraft operations. [1] The Washington ARTCC covers 165,000 square miles (430,000 km 2) of airspace that includes airports in Maryland, Pennsylvania, West Virginia, Delaware, New Jersey, Virginia, and North Carolina.
