What must a pilot do to enter the airspace around Washington D.C.?

To enter the airspace around Washington D.C., a pilot is required to file a flight plan and contact Air Traffic Control (ATC) before entry. This requirement is in place due to the sensitive nature of the airspace, which includes restricted areas surrounding national landmarks and government buildings. Engaging with ATC ensures that pilots receive necessary clearance and instructions, which helps maintain a high level of safety and security in the area.

Pilots must provide information about their intended flight, including their route and altitude, so ATC can manage the traffic and prevent conflicts with other aircraft. This procedure is crucial for maintaining order in a busy airspace that has strict regulations and protocols to safeguard national security interests. Therefore, having proper communication and flight planning with ATC is essential for a pilot wishing to operate in this airspace.
