Ronald Reagan Washington National Airport (DCA), located near the heart of the US capital, is a key hub for American Airlines and its regional brand, American Eagle. Known for its scenic approach over the Potomac River, the airport presents a unique challenge for pilots due to restricted airspace over Washington D.C.
The primary runway at DCA is 01/19, which runs north to south. When approaching from the north, aircraft use what is known as the river visual approach. This path allows pilots to visually navigate using the Potomac River, offering spectacular views of the city. However, this route serves a critical purpose beyond sightseeing: it avoids restricted airspace areas P-56A and P-56B.
According to Washington National Airport, P-56A spans from the Lincoln Memorial to the US Capitol Building and includes sensitive sites like the White House. Meanwhile, P-56B covers a half-mile radius around the Vice President's residence at the US Naval Observatory. The Federal Aviation Administration (FAA) and US Secret Service enforce these restrictions strictly.
