An air defense identification zone (ADIZ) has existed since February 10, 2003, [1] around the Baltimore-Washington Metropolitan Area to restrict air traffic near Washington, D.C.
The ADIZ was established as a precursor to the US invasion of Iraq in 2003. [2] It has been erroneously connected to the September 11 attacks as a temporary measure to prevent further attacks. [ citation needed ] It was made permanent in 2008. [3]
Despite efforts by the Federal Aviation Administration to inform pilots of the ADIZ, there are still many unauthorized incursions by unsuspecting pilots. A pilot who violates the boundaries may be intercepted by military aircraft and escorted to the nearest airport. [4] [5]
The ADIZ (now known by its components, the Flight Restricted Zone and Special Flight Rules Area) was created by the FAA in response to demands by a working group that became formalized as the National Capital Region Coordination Center. The U.S. Congress has never legitimized these restrictions, and any consideration of opposing the Executive Branch's actions became politically unpalatable in the wake of two mishaps that led to the evacuation of the Capitol. [6] [7] One involved a plane carrying Ernie Fletcher, the Governor of Kentucky, which led to an evacuation in 2004. [8] The other, almost a year later, involved a Cessna 150 flown by a student pilot accompanied by a pilot who was not familiar with the ADIZ rules, using an outdated chart.
The original Washington ADIZ was roughly co-extensive with the Class B airspace around Washington. On August 30, 2007, the dimensions of the ADIZ were changed to a 30-nautical-mile-radius (35 mi; 56 km) circle centered on the Ronald Reagan Washington National Airport (DCA) VOR/DME (located at 38°51′34″N77°2′11″W / 38.85944°N 77.03639°W ), with a small triangular cutout for Leesburg Executive Airport (JYO). This change reduced the size of the ADIZ by 1,800 sq mi (4,700 km2) and removed 33 airports from its coverage.
Within the ADIZ is an even more sensitive zone designated the Washington, D.C. Metropolitan Area Flight Restricted Zone (DC FRZ). The DC FRZ extends approximately 13–15 nmi (15–17 mi; 24–28 km) around the DCA VOR/DME. Flight within the FRZ is restricted to governmental, certain scheduled commercial and a limited set of waivered flights. Two general aviation airports (known as the "Maryland 3" or the "DC 3") are located inside the DC FRZ: College Park Airport (CGS) and Potomac Airport (VKX). [9] Washington Executive/Hyde Field (W32) closed permanently in 2022. [10]
Pilots' groups, led by the Aircraft Owners and Pilots Association (AOPA), have argued that the ADIZ is unnecessary and has a harmful effect on the economy of small airports and aviation-related businesses in and near the ADIZ. [11] Pilots involved in law enforcement have described the ADIZ as a "major, unnecessary burden on pilots and air traffic controllers with almost no increased security benefit." [12] AOPA and other groups are hoping to persuade Congress to lift or ease the ADIZ restrictions from Washington airspace – or at the very least to dramatically improve its operational aspects.
In 2006, the FAA issued a Notice of Proposed Rulemaking (NPRM) docket number 17005 concerning making the temporary rules permanent. Over 20,000 responses were received, the vast majority of them in opposition to making the temporary rules permanent. [13] There were two public hearings held by the FAA in the Washington D.C. area on the NPRM. All speakers were opposed to making the NPRM permanent [ citation needed ]. The FAA published transcripts of the public hearings. The transcripts were later withdrawn from the public as they were alleged to contain Sensitive Security Information, but were returned following review. [14]
On August 30, 2007, the FAA implemented new rules for air traffic controllers and issued revised NOTAMs for pilots flying in the ADIZ. Although the NOTAMs and FAA procedures state that no radar services will be provided to pilots unless requested, air traffic controllers at Potomac TRACON are providing such services. This is due to a memorandum from the Potomac TRACON Air Traffic Manager to air traffic controllers stating that a certain paragraph (2-1-2) of the Air Traffic Control handbook (7110.65) is still applicable when providing ATC Security Services. [15]
Effective February 9, 2009, any pilots flying VFR within a 60-nautical-mile (110 km) radius centered on the ADIZ are required to complete training about the ADIZ. This training can be completed online through a course called "Navigating the New DC ADIZ" (now "DC Special Flight Rules Area"). [16] Pilots may also complete the required training by attending a seminar offered at a Flight Standards District Office. Pilots must obtain a certificate which proves that the training has been completed. This certificate is not required to be carried with the pilot, but must be produced when requested from law enforcement or other agencies. Pilots flying IFR are not subject to this requirement. [17]
On February 17, 2009, the status of the ADIZ was scheduled to change from a temporary flight restriction to a permanent special flight rules area. [18] On February 6, 2009, White House officials declined a request to postpone the implementation. [19]
In February 2012, the FAA Modernization and Reform Act of 2012 [20] required a joint plan to be submitted in 180 days by the Administrator of the Federal Aviation Administration, in consultation with the Secretaries of Homeland Security and Defense.
The plan shall outline specific changes to the D.C. Metropolitan Area Special Flight Rules Area that will decrease operational impacts and improve general aviation access to airports in the National Capital Region that are currently impacted by the zone. [20]
In June 2014, Leesburg airport traffic was granted authority to perform local traffic pattern practice without a SFRA plan filed while operating under tower control without departing the pattern. [21]
In May 2005, NORAD started using a laser warning system to warn pilots that cross into restricted airspace. The bright laser beams, which flash red-red-green, are easily seen, even during daylight. The laser beams can be seen 15 to 20 miles (24 to 32 km) away. Other pilots are unlikely to see the lasers because, when activated, the directional beams are pointed at the aircraft that has crossed into restricted airspace. Multiple lasers could be activated. These lasers do not harm the eyes of aircrew or passengers. [22] [23] [24]
Air traffic control (ATC) is a service provided by ground-based air traffic controllers (people) who direct aircraft on the ground and through a given section of controlled airspace, and can provide advisory services to aircraft in non-controlled airspace. The primary purpose of ATC worldwide is to prevent collisions, organise and expedite the flow of traffic in the air, and provide information and other support for pilots.
Aviation is the design, development, production, operation, and use of aircraft, especially heavier-than-air aircraft. Articles related to aviation include:
Airspace is the portion of the atmosphere controlled by a country above its territory, including its territorial waters or, more generally, any specific three-dimensional portion of the atmosphere. It is not the same as outer space which is the expanse or space outside the Earth and aerospace which is the general term for Earth's atmosphere and the outer space within the planet's vicinity.
A NOTAM is a notice filed with an aviation authority to alert aircraft pilots of potential hazards along a flight route or at a location that could affect the flight. NOTAMs are notices or advisories that contain information concerning the establishment, conditions or change in any aeronautical facility, service, procedure or hazard, the timely knowledge of which may be essential to personnel and systems concerned with flight operations.
Washington Executive Airport, also known as Washington Executive Airpark or Hyde Field, was a public use general aviation airport located 2 miles (3.2 km) southwest of the central business district (CBD) of Clinton, in Prince George's County, Maryland, United States. The airport ceased operations on November 30, 2022, following a bankruptcy sale of the property.
In aviation, a non-towered airport is an airport without a control tower, or air traffic control (ATC) unit. The vast majority of the world's airports are non-towered. In the United States, there are close to 20,000 non-towered airports compared to approximately 500 airports with control towers. Airports with a control tower without 24/7 ATC service follow non-towered airport procedures when the tower is closed but the airport remains open, for example at night.
Special use airspace (SUA) is a type of special airspaces in the United States designated for operations of a nature such that limitations may be imposed on aircraft not participating in those operations. Often these operations are of a military nature. The designation of SUAs identifies for other users the areas where such activity occurs, provides for segregation of that activity from other users, and allows charting to keep airspace users informed of potential hazards.
The East River Special Flight Rules Area (SFRA), formally known as the East River class-B exclusion, is a section of airspace above the East River in New York City in which flight is permitted under visual flight rules (VFR). Formerly, this could be done without being in contact with air traffic control. Pilots operating within the SFRA are expected to self-announce on a designated frequency of 123.075 MHz, and to maintain appropriate separation visually.
A prohibited airspace is an area (volume) of airspace within which flight of aircraft is not allowed, usually due to security concerns. It is one of many types of special use airspace designations and is depicted on aeronautical charts with the letter "P" followed by a serial number. It differs from restricted airspace in that entry is typically forbidden at all times from all aircraft and is not subject to clearance from ATC or the airspace's controlling body.
The United States airspace system's classification scheme is intended to maximize pilot flexibility within acceptable levels of risk appropriate to the type of operation and traffic density within that class of airspace – in particular to provide separation and active control in areas of dense or high-speed flight operations.
In United States aviation, a special flight rules area (SFRA) is a region in which the normal regulations of flight do not apply in whole or in part, especially regulations concerning airspace classification, altitude, course, and speed restrictions, and the like.
The Next Generation Air Transportation System (NextGen) is an ongoing United States Federal Aviation Administration (FAA) project to modernize the National Airspace System (NAS). The FAA began work on NextGen improvements in 2007 and plans to finish the final implementation segment by 2030. The goals of the modernization include using new technologies and procedures to increase the safety, efficiency, capacity, access, flexibility, predictability, and resilience of the NAS while reducing the environmental impact of aviation.
The Air Defense Identification Zone of North America is an air defense identification zone (ADIZ) that covers the airspace surrounding the United States and Canada – in which the ready identification, location, and control of civil aircraft over land or water is required in the interest of national security. This ADIZ is jointly administered by the civilian air traffic control authorities and the militaries of both nations, under the auspices of the North American Aerospace Defense Command (NORAD). The Federal Aviation Administration (FAA) handles the requests of international aircraft and Transport Canada handles Canadian requests. Any aircraft flying in these zones without authorization may be identified as a threat and treated as an enemy aircraft, potentially leading to interception by fighter aircraft.
The National Airspace System (NAS) is the airspace, navigation facilities and airports of the United States along with their associated information, services, rules, regulations, policies, procedures, personnel and equipment. It includes components shared jointly with the military. It is one of the most complex aviation systems in the world, and services air travel in the United States and over large portions of the world's oceans.
The Air Traffic Organization (ATO) is an air navigation service provider in the United States of America. The ATO is the operational division of the Federal Aviation Administration (FAA).
Automatic Dependent Surveillance–Broadcast (ADS-B) is an aviation surveillance technology and form of electronic conspicuity in which an aircraft determines its position via satellite navigation or other sensors and periodically broadcasts its position and other related data, enabling it to be tracked. The information can be received by air traffic control ground-based or satellite-based receivers as a replacement for secondary surveillance radar (SSR). Unlike SSR, ADS-B does not require an interrogation signal from the ground or from other aircraft to activate its transmissions. ADS-B can also receive point-to-point by other nearby equipped "ADS-B In" equipped aircraft to provide traffic situational awareness and support self-separation. ADS-B is "automatic" in that it requires no pilot or external input to trigger its transmissions. It is "dependent" in that it depends on data from the aircraft's navigation system to provide the transmitted data.
A ground stop is an air traffic control procedure that requires all aircraft that fit certain criteria to remain on the ground. This could be airport specific or perhaps equipment or airspace specific, depending on the exact event that caused the ground stop to occur. Downstream effects can occur from the hazard, causes flights to be delayed or canceled and flight crew being unable to reach the location of their next scheduled aircraft.
On August 8, 2009, at 11:53 a.m. (15:53 UTC), nine people died when a tour helicopter and a small private airplane collided over the Hudson River near Frank Sinatra Park in Hoboken, New Jersey, United States. The aircraft were in an area known as the "Hudson River VFR Corridor", which extends from the surface of the river to altitudes of 800 to 1,500 ft at various locations along the Hudson River in the immediate area of New York City. Within this corridor, aircraft operate under visual flight rules (VFR), under which the responsibility to see and avoid other air traffic rests with the individual pilots rather than with the air traffic controller (ATC).
A contact approach is an approach available to aircraft operating on an instrument flight rules (IFR) flight plan, where the pilot may deviate from the published instrument approach procedure (IAP) and proceed to the destination airport by visual reference to the surface. It is similar to a visual approach, except that the pilot is not required to have the destination airport nor the preceding aircraft in sight at all times during the approach, and the visibility requirements are less stringent.
On Thursday, January 15, 1987, SkyWest Airlines Flight 1834, a Swearingen SA-226TC, and a Mooney M20 were involved in a midair collision at 12:52 MST (UTC−7) near Kearns, Utah, a suburb southwest of Salt Lake City. All ten aboard the two aircraft were killed: two pilots and six passengers aboard the METRO II and two aboard the Mooney.
