Washington County Airport (Pennsylvania)
Washington County Airport is three miles (5 km) southwest of Washington in South Franklin Township, Pennsylvania. It is owned and operated by Washington County and is in the Greater Pittsburgh metropolitan area. Most U.S. airports use the same three-letter location identifier for the FAA and IATA, but Washington County Airport is AFJ to the FAA and WSG to the IATA. At one time, it hosted memorials for DeLloyd Thompson, a famous early pilot from Washington County, but those memorials had been discarded. In 2013 and 2014, Clay Kilgore, executive director of the Washington County Historical Society, led an effort to restore the plaques to the airport. Facilities The airport covers and has 37 T-hangars, seven corporate hangars and seven businesses that employ about thirty people. The airport is a relief airport for other airports such as Pittsburgh International Airport and Allegheny County Airport. Washington County Airport has a runway and a full parallel taxiway ...

Washington County, Pennsylvania
Washington County is a county in the Commonwealth of Pennsylvania. As of the 2020 census, the population was 209,349. Its county seat is Washington. Washington County is part of the Pittsburgh, PA Metropolitan Statistical Area. The county is home to Washington County Airport, three miles (5 km) southwest of Washington. History The county was created on March 28, 1781, from part of Westmoreland County. The city and county were both named after American Revolutionary War leader George Washington, who eventually became the first President of the United States. The town of Charleroi got its name from the Belgian city of Charleroi. There lived many Belgian immigrants in the Monongahela area at the end of the 19th century, some of whom were glass makers. Geography According to the U.S. Census Bureau, the county has a total area of , of which is land and (0.5%) is water.

Taxiway
A taxiway is a path for aircraft at an airport connecting runways with aprons, hangars, terminals and other facilities. They mostly have a hard surface such as asphalt or concrete, although smaller general aviation airports sometimes use gravel or grass. Most airports do not have a specific speed limit for taxiing (though some do). There is a general rule on safe speed based on obstacles. Operators and aircraft manufacturers might have limits. Typical taxi speeds are 20–30 knots (37–56 km/h; 23–35 mph). High-speed exit Busy airports typically construct high-speed or rapid-exit taxiways to allow aircraft to leave the runway at higher speeds. This allows the aircraft to vacate the runway quicker, permitting another to land or take off in a shorter interval of time. This is accomplished by reducing the angle the exiting taxiway intercepts the runway at to 30 degrees, instead of 90 degrees, thus increasing the speed at which the aircraft can exit the runway onto the taxiway ...

Airports In Pennsylvania
An airport is an aerodrome with extended facilities, mostly for commercial air transport. Airports usually consists of a landing area, which comprises an aerially accessible open space including at least one operationally active surface such as a runway for a plane to take off and to land or a helipad, and often includes adjacent utility buildings such as control towers, hangars and terminals, to maintain and monitor aircraft. Larger airports may have airport aprons, taxiway bridges, air traffic control centres, passenger facilities such as restaurants and lounges, and emergency services. In some countries, the US in particular, airports also typically have one or more fixed-base operators, serving general aviation. Operating airports is extremely complicated, with a complex system of aircraft support services, passenger services, and aircraft control services contained within the operation. Thus airports can be major employers, as well as important hubs for tourism ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Air Charter
Air charter is the business of renting an entire aircraft (i.e., chartering) as opposed to individual aircraft seats (i.e., purchasing a ticket through a traditional airline). Regulation Charter – also called air taxi or ad hoc – flights require certification from the associated country's civil aviation authority. The regulations are differentiated from typical commercial/passenger service by offering a non-scheduled service. Analogous regulations generally also apply to air ambulance and cargo operators, which are often also ad hoc for-hire services. United States In the U.S. these flights are regulated under FAA Part 135. There are some cases where a charter operator can sell scheduled flights, but only in limited quantities. As of 2021, the FAA had made it a priority to crack down on unauthorised charter flights, according to industry experts. Types of service There are several business models which offer air charter services from the traditional charter operator to ...

General Aviation
General aviation (GA) is defined by the International Civil Aviation Organization (ICAO) as all civil aviation aircraft operations with the exception of commercial air transport or aerial work, which is defined as specialized aviation services for other purposes. However, for statistical purposes ICAO uses a definition of general aviation which includes aerial work. General aviation thus represents the " private transport" and recreational components of aviation. Definition The International Civil Aviation Organization (ICAO) defines civil aviation aircraft operations in three categories: General Aviation (GA), Aerial Work (AW) and Commercial Air Transport (CAT). Aerial work operations are separated from general aviation by ICAO by this definition. Aerial work is when an aircraft is used for specialized services such as agriculture, construction, photography, surveying, observation and patrol, search and rescue, and aerial advertisement. However, for statistical purpose ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Instrument Landing System
In aviation, the instrument landing system (ILS) is a precision radio navigation system that provides short-range guidance to aircraft to allow them to approach a runway at night or in bad weather. In its original form, it allows an aircraft to approach until it is over the ground, within a of the runway. At that point the runway should be visible to the pilot; if it is not, they perform a missed approach. Bringing the aircraft this close to the runway dramatically increases the range of weather conditions in which a safe landing can be made. Other versions of the system, or "categories", have further reduced the minimum altitudes, runway visual ranges (RVRs), and transmitter and monitoring configurations designed depending on the normal expected weather patterns and airport safety requirements. ILS uses two directional radio signals, the ''localizer'' (108 to 112 MHz frequency), which provides horizontal guidance, and the ''glideslope'' (329.15 to 335 MHz frequen ...

Automated Surface Observing System
Airport weather stations are automated sensor suites which are designed to serve aviation and meteorological operations, weather forecasting and climatology. Automated airport weather stations have become part of the backbone of weather observing in the United States and Canada and are becoming increasingly more prevalent worldwide due to their efficiency and cost-savings. System types within the United States In the United States, there are several varieties of automated weather stations that have somewhat subtle but important differences. These include the automated weather observing system (AWOS) and the automated surface observing system (ASOS). Automated weather observing system (AWOS) The automated weather observing system (AWOS) units are mostly operated, maintained and controlled by state or local governments and other non-federal entities and are certified under the FAA non-federal AWOS Program. The FAA completed an upgrade of the 230 FAA owned AWOS and former automa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Remote Communications Outlet
Remote communications outlets (RCO) are remote aviation band radio transceivers, established to extend the communication capabilities of Flight Information Centres (FIC) and flight service stations (FSS). Pilots can find RCO frequencies in charts or publications such as the Chart Supplement or Canada Flight Supplement. The RCO is used to make a radio call to the outlet as if the pilot were making the call directly to the FSS or FIC. The outlet will relay the call (and the briefer's response) automatically. RCOs are sometimes confused with RTRs, or remote transmitter/receivers. In fact, the difference between the two is subtle. While RCOs serve flight service stations, RTRs serve terminal air traffic control facilities. RCOs and RTRs may be UHF or VHF and are divided into a variety of classes determined by the number of transmitters or receivers. Classes A through G are used mainly for air/ground communications. Class O facilities were created specifically to provide ground-to-gro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Non-directional Beacon
A non-directional beacon (NDB) or non-directional radio beacon is a radio beacon which does not include directional information. Radio beacons are radio transmitters at a known location, used as an aviation or marine navigational aid. NDB are in contrast to directional radio beacons and other navigational aids, such as low-frequency radio range, VHF omnidirectional range (VOR) and tactical air navigation system (TACAN). NDB signals Ground conductivity, follow the curvature of the Earth, so they can be received at much greater distances at lower altitudes, a major advantage over VOR. However, NDB signals are also affected more by atmospheric conditions, mountainous terrain, coastal refraction and electrical storms, particularly at long range. The system, developed by United States Air Force (USAF) Captain Albert Francis Hegenberger, was used to fly the world's first instrument approach on May 9, 1932. Types of NDBs NDBs used for aviation are standardised by International Civil ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Distance Measuring Equipment
In aviation, distance measuring equipment (DME) is a radio navigation technology that measures the slant range (distance) between an aircraft and a ground station by timing the propagation delay of radio signals in the frequency band between 960 and 1215 megahertz (MHz). Line-of-visibility between the aircraft and ground station is required. An interrogator (airborne) initiates an exchange by transmitting a pulse pair, on an assigned 'channel', to the transponder ground station. The channel assignment specifies the carrier frequency and the spacing between the pulses. After a known delay, the transponder replies by transmitting a pulse pair on a frequency that is offset from the interrogation frequency by 63 MHz and having specified separation.''Annex 10 to the Convention on International Civil Aviation, Volume I – Radio Navigation Aids''; International Civil Aviation Organization; International Standards and Recommended Practices. DME systems are used worldwide, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Localizer
An instrument landing system localizer, or simply localizer (LOC), is a system of horizontal guidance in the instrument landing system, which is used to guide aircraft along the axis of the runway. Principle of operation In aviation, a localizer is the lateral component of the ''instrument landing system'' (ILS) for the runway centerline when combined with the vertical glide slope, not to be confused with a locator, although both are parts of aviation navigation systems. A localizer (like a glideslope) requires both a transmitting airport runway system and receiving cockpit instruments. An older aircraft without an ILS receiver cannot take advantage of any ILS facilities at any runway, and much more importantly, the most modern aircraft have no use of their ILS instruments at runways which lack ILS facilities. In parts of Africa and Asia large airports may lack any kind of transmitting ILS system. Some runways have ILS only in one direction, this can however still be used for ...

Allegheny County Airport
Allegheny County Airport is in West Mifflin, Pennsylvania, 7 miles (11 km) southeast of Pittsburgh. It is the fifth-busiest airport in Pennsylvania following Philadelphia, Pittsburgh, Allentown, and Harrisburg. The airport is owned by the Allegheny County Airport Authority and is the primary FAA-designated reliever airport for Pittsburgh International Airport. Allegheny County Airport was dedicated on September 11, 1931. When it was completed, it was third-largest airport in the country and the only hard-surface airport in the country. It was historically the main entrance to metro Pittsburgh via air from its inception until June 1952, when the Greater Pittsburgh Airport (now Pittsburgh International Airport – KPIT) opened for commercial aviation. Like many historic municipal fields, Allegheny serves small and mid-sized private, corporate and commercial traffic well, but was not built to handle jet airliners. A Boeing 727 owned by Rockwell and two DC-9's however were ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
