Avionics is a portmanteau of "aviation electronics". It comprises electronic systems for use on aircraft, artificial satellites and spacecraft, comprising communications, navigation and the display and management of multiple systems. It also includes the hundreds of systems that are fitted to aircraft to meet individual roles; these can be as simple as a search light for a police helicopter or as complicated as the tactical system for an Airborne Early Warning platform.
The Global Positioning System (GPS) is a U.S. space-based global navigation satellite system. It provides reliable positioning, navigation, and timing services to worldwide users on a continuous basis in all weather, day and night, anywhere on or near the Earth which has an unobstructed view of four or more GPS satellites. GPS is made up of three segments: Space, Control and User.
A radio direction finder (RDF) is a device for finding the direction to a radio source. Due to radio's ability to travel very long distances and "over the horizon", it makes a particularly good navigation system for ships, small boats, and aircraft that might be some distance from their destination.
An Inertial Navigation System (INS) is a navigation aid that uses a computer, motion sensors and rotation sensors to continuously calculate via dead reckoning the position, orientation, and velocity (direction and speed of movement) of a moving object without the need for external references. It is used on vehicles such as ships, aircraft, submarines, guided missiles, and spacecraft.
Honeywell (legally Honeywell International Inc. ) is a major conglomerate company that produces a variety of consumer products, engineering services, and aerospace systems for a wide variety of customers, from private consumers to major corporations and governments. Honeywell is a Fortune 500 company with a workforce of approximately 128,000, of which approximately 58,000 are employed in the United States. The company is headquartered in Morristown, New Jersey.
Avionics software is embedded software with legally-mandated safety and reliability concerns used in avionics. The main difference between avionic software and conventional embedded software is that the development process is required by law and is optimized for safety. Interestingly, some claim that the process described below is only slightly slower and more costly (perhaps 15 percent) than the normal ad-hoc processes used for commercial software.
The heading indicator (Directional Gyro or DG) is a flight instrument used in an aircraft to inform the pilot of their heading. It is sometimes referred to by its older name, the directional gyro, or (UK usage) direction indicator or DI.
An attitude indicator (AI), gyro horizon or artificial horizon, is an instrument used in an aircraft to inform the pilot of the orientation of the aircraft relative to earth. It indicates pitch (fore and aft tilt) and bank or roll (side to side tilt) and is a primary instrument for flight in instrument meteorological conditions. Attitude indicators also have significant application under visual flight rules, though some light aircraft do not have them installed.
An autopilot is a mechanical, electrical, or hydraulic system used to guide a vehicle without assistance from a human being. Most people understand an autopilot to refer specifically to aircraft, but self-steering gear for ships, boats, space craft and missiles are sometimes also called by this term. The autopilot of an aircraft is sometimes referred to as "George."
Albinism (from Latin albus, "white"; see, also called achromia, achromasia, or achromatosis) is a congenital disorder characterized by the complete or partial absence of pigment in the skin, hair and eyes due to absence or defect of an enzyme involved in the production of melanin. Albinism results from inheritance of recessive gene alleles and is known to affect all vertebrates, including humans. The most common term used for an organism affected by albinism is "albino".
A Cornish game hen, also sometimes called a Cornish hen, poussin, Rock Cornish hen, or simply Rock Cornish, is a young chicken sold whole. Despite the name, it is not a game bird, but actually a typical chicken that is slaughtered at a young age and therefore is smaller in size. Though the bird is called a "hen," it can be either male or female. Most sources credit Alphonsine and Jacques Makowsky of Connecticut for developing the small bird in the mid-1950s.
The Gau Bayreuth, until 1942 named Gau Bayerische Ostmark, was an administrative division of Nazi Germany in Lower Bavaria, Upper Palatinate and Upper Franconia,Bavaria from 1933 to 1945. Previous to that, since 1926, it was the regional subdivision of the Nazi Party in this region.
