Flight Tracking
Flight tracking is a service that involves the tracking of flights, aircraft and airport activity, often using software. Overview Flight tracking enables travellers as well as those picking up travellers after a flight to know whether a flight has landed or is on schedule, for example to determine whether it is time to go to the airport. Aircraft carry ADS-B transponders, which transmit information such as the aircraft ID, GPS position, and altitude as radio signals. These radio transmission are collected by civilian ADS-B receivers located in the vicinity of the aircraft. These ADS-B receivers are only able to collect information on flights within radio-range of their position, so the data they collect is usually sent to a central server which aggregates feeds from numerous individual receivers throughout the world. Flight tracking can be integrated with travel management and travel tracking services, allowing increased automation of travel software. This application of fligh ...

English Language
English is a West Germanic language that developed in early medieval England and has since become a English as a lingua franca, global lingua franca.

English is the list of languages by total number of speakers, most spoken language in the world, primarily due to the global influences of the former British Empire (succeeded by the Commonwealth of Nations) and the United States. English is the list of languages by number of native speakers, third-most spoken native language, after Mandarin Chinese and Spanish language, Spanish; it is also the most widely learned second language in the world, with more second-language speakers than native speakers. English is either the official language or one of the official languages in list of countries and territories where English ...

Android (operating System)
Android is an operating system based on a modified version of the Linux kernel and other open-source software, open-source software, designed primarily for touchscreen-based mobile devices such as smartphones and tablet computer, tablets. Android has historically been developed by a consortium of developers known as the Open Handset Alliance, but its most widely used version is primarily developed by Google. First released in 2008, Android is the world's Usage share of operating systems, most widely used operating system; the latest version, released on June 10, 2025, is Android 16. At its core, the operating system is known as the Android Open Source Project (AOSP) and is free and open-source software (FOSS) primarily licensed under the Apache License.

Air Traffic Control
Air traffic control (ATC) is a service provided by ground-based air traffic controllers 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 is to prevent collisions, organise and expedite the flow of traffic in the air, and provide information and other support for pilots. Personnel of air traffic control monitor aircraft location in their assigned airspace by radar and communicate with the pilots by radio. To prevent collisions, ATC enforces Separation (air traffic control), traffic separation rules, which ensure each aircraft maintains a minimum amount of 'empty space' around it at all times. It is also common for ATC to provide services to all General aviation, private, Military aviation, military, and commercial aircraft operating within its airspace; not just civilian aircraft. Depending on the type of flight and the class of airspace, AT ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
High Frequency Data Link
High Frequency Data Link (HFDL) is an ACARS communications medium used to exchange data such as Aeronautical Operational Control (AOC) messages, Controller Pilot Data Link Communications (CPDLC) messages and Automatic Dependent Surveillance (ADS) messages between aircraft end-systems and corresponding ground-based HFDL ground stations. Using the unique propagation characteristics of high-frequency radio waves, the ground stations provide data link communications to properly equipped aircraft operating anywhere in the world. As a result, pilots can always communicate with someone on the ground. Avionics supporting HFDL To use the service, an aircraft only needs a Communications Management Unit (CMU), or equivalent and an HFDL data radio. The CMU is an airborne communications router that interfaces with many aircraft communications systems including SATCOM, VHF, HFDL, FMS and others. Global coverage Today, HFDL is an air/ground data link standard with coverage in virtually ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Transponder (aeronautics)
A transponder (short for ''trans''mitter-res''ponder'' and sometimes abbreviated to XPDR, XPNDR, TPDR or TP) is an electronic device that produces a response when it receives a radio-frequency interrogation. Aircraft have transponders to assist in identifying them on air traffic control radar. Collision avoidance systems have been developed to use transponder transmissions as a means of detecting aircraft at risk of colliding with each other. Air traffic control (ATC) units use the term "squawk" when they are assigning an aircraft a transponder code, e.g., "Squawk 7421". Squawk thus can be said to mean "select transponder code" or "squawking ''xxxx''" to mean "I have selected transponder code ''xxxx''". The transponder receives interrogation from the secondary surveillance radar on 1030 MHz and replies on 1090 MHz. Secondary surveillance radar Secondary surveillance radar (SSR) is referred to as "secondary", to distinguish it from the "primary radar" that works ...

Oligarchy
Oligarchy (; ) is a form of government in which power rests with a small number of people. Members of this group, called oligarchs, generally hold usually hard, but sometimes soft power through nobility, fame, wealth, or education; or through corporate, religious, political, or military control. Throughout history, power structures considered to be oligarchies have often been viewed as coercive, relying on public obedience or oppression to exist. Aristotle pioneered the use of the term as meaning rule by the rich, contrasting it with aristocracy, arguing that oligarchy was a corruption of aristocracy. Types Minority rule The consolidation of power by a dominant minority, whether religious or ethnic, can be considered a form of oligarchy. Examples include South Africa during apartheid, Liberia under Americo-Liberians, the Sultanate of Zanzibar, and Rhodesia. In these cases, oligarchic rule was often tied to the legacy of colonialism. In the early 20th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
