Why The FAA Moved Some Air Traffic By Just 800 Feet In Washington

The United States Federal Aviation Administration (FAA) has moved some air traffic out of Washington National Airport (DCA) just under 800 feet southwest starting on January 30, 2020. Here’s what the FAA is doing.

In a news update, the FAA announced that it had altered some air traffic flows out of Ronald Reagan Washington National Airport (DCA). This change, called HOLTB, the agency moved a waypoint 784 feet southwest. This moved north-flow departing aircraft away from the heavily protected DC-area airspace. But, aircraft will still remain over the Potomac River. Passengers should still expect some amazing views.

The FAA started this test on January 30th. Since then, it appears that the agency is pleased with the results and has now proposed to make this a permanent implementation for all north-flow departures out of DCA. The public is allowed to comment on the procedures through March 30th.

Due to the airport’s proximity to Capitol Hill and the White House, the airspace is heavily restricted. Pilots have to fly in a certain approach and departure over the Potomac River until they can fly around the restricted airspace.

Ronald Reagan Washington National Airport

This airport is a very special one in the United States. It is the closest to Washington D.C. However, it is relatively small. The airport is not allowed to handle widebodies and has restrictions on the number of flights that can operate beyond a certain radius.

Called the Perimeter Rule, this regulation limits the amount of nonstop services to Washington National Airport. Starting in 1966, this originally was limited to 650 statute miles. Then, in the 1980s, Congress expanded this 1,250 statute miles where it still remains.

There are some exemptions, however. The US Department of Transportation allows nonstop flights to select cities. These include Austin, Denver, Las Vegas, Los Angeles, Phoenix, Salt Lake City, San Francisco, San Juan, Seattle, and Portland.

The airport does, however, see lie-flat seats in business class on Delta’s transcontinental hop to Los Angeles with a premium Boeing 757.

Overall

While passengers might not notice this change, the FAA is making this shift so that aircraft stay away from heavily restricted areas. This limits unintended incursions from civil aircraft into restricted airspace.

The FAA is seeking public comment through March 30th on environmental concerns. However, the FAA is doing an environmental review for the implementation of this plan.

I’m glad someone in the FAA has a sense of humor about the route names.
