In the context of aviation and aerospace, the "Eastern Region" typically refers to one of the geographical regions used by the Federal Aviation Administration (FAA) to organize and manage air traffic control, aviation safety, and other regulatory activities in the United States.

The FAA divides the country into several regions, including:

1. Eastern Region (AR)
2. Central Region (CT)
3. Southern Region (SO)
4. Western Region (WP)
5. Alaskan Region (AL)
6. Pacific Region (PA)

The Eastern Region, also known as the "Eastern Service Area" or "Region 1," encompasses the northeastern and mid-Atlantic states, including:

• Maine
• New Hampshire
• Vermont
• Massachusetts
• Rhode Island
• Connecticut
• New York
• New Jersey
• Pennsylvania
• Delaware
• Maryland
• Washington D.C.
• Virginia
• West Virginia

This region is responsible for overseeing aviation activities, including air traffic control, airport management, and safety inspections, within its boundaries. The Eastern Region is headquartered in Jamaica, New York, and is one of the busiest and most complex regions in the country, with many major airports, including John F. Kennedy International Airport (JFK), LaGuardia Airport (LGA), and Newark Liberty International Airport (EWR).
