Fairchild Swearingen Metroliner
The Fairchild Swearingen Metroliner (previously the Swearingen Metro and later Fairchild Aerospace Metro) is a 19-seat, pressurized, twin-turboprop airliner first produced by Swearingen Aircraft and later by Fairchild Aircraft at a plant in San Antonio, Texas. Design The Metroliner was an evolution of the Swearingen Merlin turboprop-powered business aircraft. Ed Swearingen, a Texas fixed-base operator (FBO), started the developments that led to the Metro through gradual modifications to the Beechcraft Twin Bonanza and Queen Air business aircraft, which he dubbed Excalibur. A new fuselage (but with a similar nose) and vertical fin were then developed, married to salvaged and rebuilt (wet) Queen Air wings and horizontal tails, and Twin Bonanza landing gear; this became the SA26 Merlin, more or less a pressurized Excalibur. Through successive models (the SA26-T Merlin IIA and SA26-AT Merlin IIB) the engines were changed to Pratt & Whitney Canada PT6, then Garrett TPE331 t ...

Florida Air National Guard
The Florida Air National Guard (FL ANG) is the aerial militia of the State of Florida. It is, along with the Florida Army National Guard (FL ARNG), an element of the Florida National Guard. It is also an element of the Air National Guard (ANG) at the national level, falling in with the Army National Guard (ARNG) as part of the greater United States National Guard under the National Guard Bureau (NGB). As a U.S. Air Force (USAF) organization, the Florida Air National Guard is also part of the USAF's Air Reserve Component (ARC), a position it shares with its "federal" ARC partner, the Air Force Reserve Command (AFRC). As state militia units, the units in the Florida Air National Guard are not in the normal United States Air Force chain of command. FL ANG units remain under the jurisdiction of the Governor of Florida through the office of the Florida Adjutant General, also known as the "TAG," unless they are federalized by order of the President of the United States. This juris ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Air National Guard
The Air National Guard (ANG), also known as the Air Guard, is a federal military reserve force of the United States Air Force, as well as the air militia of each U.S. state, the District of Columbia, the Commonwealth of Puerto Rico, and the territories of Guam and the U.S. Virgin Islands. It, along with each state's, district's, commonwealth's or territory's Army National Guard component, makes up the National Guard of each state and the districts, commonwealths and territories as applicable. When Air National Guard units are used under the jurisdiction of the state governor they are fulfilling their militia role. However, if federalized by order of the President of the United States, Air National Guard units become an active part of the United States Air Force. They are jointly administered by the states and the National Guard Bureau, a joint bureau of the Army and Air Force that oversees the United States National Guard. Air National Guard operating forces are structur ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

War On Drugs
The war on drugs is a global campaign, led by the United States federal government, of drug prohibition, military aid, and military intervention, with the aim of reducing the illegal drug trade in the United States.Cockburn and St. Clair, 1998: Chapter 14 The initiative includes a set of drug policies that are intended to discourage the production, distribution, and consumption of psychoactive drugs that the participating governments and the United Nations have made illegal. The term was popularized by the media shortly after a press conference given on June 18, 1971, by President Richard Nixon—the day after publication of a special message from President Nixon to the Congress on Drug Abuse Prevention and Control—during which he declared drug abuse "public enemy number one". That message to the Congress included text about devoting more federal resources to the "prevention of new addicts, and the rehabilitation of those who are addicted" but that part did not receive ...

Federal Emergency Management Agency
The Federal Emergency Management Agency (FEMA) is an agency of the United States Department of Homeland Security (DHS), initially created under President Jimmy Carter by Presidential Reorganization Plan No. 3 of 1978 and implemented by two Executive Orders on April 1, 1979. The agency's primary purpose is to coordinate the response to a disaster that has occurred in the United States and that overwhelms the resources of local and state authorities. The governor of the state in which the disaster occurs must declare a state of emergency and formally request from the President that FEMA and the federal government respond to the disaster. The only exception to the state's gubernatorial declaration requirement occurs when an emergency or disaster takes place on federal property or to a federal asset—for example, the 1995 bombing of the Alfred P. Murrah Federal Building in Oklahoma City, Oklahoma, or the Space Shuttle ''Columbia'' in the 2003 return-flight disaster. While o ...

Phased Array
In antenna theory, a phased array usually means an electronically scanned array, a computer-controlled array of antennas which creates a beam of radio waves that can be electronically steered to point in different directions without moving the antennas. In a simple array antenna, the radio frequency current from the transmitter is fed to multiple individual antenna elements with the proper phase relationship so that the radio waves from the separate elements combine ( superpose) to form beams, to increase power radiated in desired directions and suppress radiation in undesired directions. In a phased array, the power from the transmitter is fed to the radiating elements through devices called '' phase shifters'', controlled by a computer system, which can alter the phase or signal delay electronically, thus steering the beam of radio waves to a different direction. Since the size of an antenna array must extend many wavelengths to achieve the high gain needed for narrow ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
