Main article: Iraqi no-fly zones

In 1992, France, the United Kingdom and the United States intervened in Kurdish-Iraqi dispute in northern Iraq by establishing a no-fly zone in which Iraqi aircraft were prevented from flying. The intent of the no-fly zone was to prevent possible bombing and chemical attacks against the Kurdish people by the Iraqi regime. The legality of this operation is a subject of debate. Proponents claim that the no-fly zone was implicitly authorized by United Nations Security Council Resolution 688. Critics point out that Resolution 688 does not actually authorize or mention such an operation.

In the United States, the colloquial phrase "no-fly zone" has no official meaning. What most people would consider a "no-fly zone" is termed a "Prohibited Area" by the Federal Aviation Administration. These Prohibited Areas are listed in the Federal Register and are depicted on all aeronautical charts.

The following Prohibited Areas are in effect at all times:

• Washington, D.C., National Mall area around White House, U.S. Capitol (Prohibited Area 56A)
• Washington, D.C., U.S. Naval Observatory, the home of the Vice President of the United States (Prohibited Area 56B)
• Amarillo, Texas, Pantex nuclear assembly plant (Prohibited Area 47)
• Boundary Waters Canoe Area Wilderness in northern Minnesota (Prohibited Areas 204, 205, and 206)
• Crawford, Texas, Ranch of George W. Bush (Prohibited Area 49)
• Kennebunkport, Maine, site of Bush Compound - (Prohibited Area 67)
• Mount Vernon, Virginia, home of George Washington (to prevent vibrations) (Prohibited Area 73)
• Thurmont, Maryland, site of Presidential retreat Camp David (Prohibited Area 40)

In addition to areas completely off limits to civil aviation, a variety of other airspace restrictions exist in the United States. Some prominent ones include the the Flight Restriction Zone (FRZ) encompassing all airspace up to 18,000 feet within approximately 15 nautical miles of Ronald Reagan National Airport around Washington, D.C. Flights within this airspace, while not entirely prohibited, are highly restricted. All pilots flying within the FRZ are required to undergo a background check and fingerprinting. An additional area encompassing most of the Baltimore-Washington D.C. metropolitan area requires the filing of a flight plan and communication with air traffic control.

Furthermore, Temporary Flight Restrictions (TFRs) are frequently issued around the country. Whenever the President leaves Washington, D.C., a TFR is issued to prohibit flights near his location. TFRs are also issued to ensure a safe environment for firefighting operations in the case of wildfires and for other reasons as necessary. A TFR was quickly issued around the crash site of Cory Lidle's airplane in New York City. Later, a broader TFR was issued to require pilots traveling over the East River to obtain air traffic control clearance. TFRs are issued by a Notice to Airmen (NOTAM), which are available online and by calling a Flight Service Station.
