Aviation comes from the Latin avis meaning “bird,” an appropriate translation given that aviation deals with travel by air, specifically in a plane. The aviation industry is the business sector dedicated to manufacturing and operating all types of aircraft.
Avionics are the electronic systems used on aircraft, artificial satellites, and spacecraft. Avionic systems include communications, navigation, the display and management of multiple systems, and the hundreds of systems that are fitted to aircraft to perform individual functions.
Everything regarding aviation is rather expensive. Especially the hardware, as it requires a great level of precision. Most modern AHRS use micro-mechanical internals, magnetometers and other complex units. These units need to maintain precision at all times.
Avionics refers to the electrical equipment used in aircraft, spacecraft, etc. Avionics Engineers work in the aerospace industry designing and developing aircraft, spacecraft, satellites and spacecraft avionics instrumentation.
In order to pursue a career as an avionics technician, you must earn a certification in avionics. Candidates must complete an 18-month course at an FAA-approved institution where they will learn about analog and digital circuits, radio transmitters and receivers, power supplies, antenna theory, and more.
The six basic aircraft instruments are an Altimeter (Pitot Static System), Airspeed Indicator (Pitot Static System), Vertical Speed Indicator (Pitot Static System), Attitude Indicator (Gyroscopic System), Heading Indicator (Gyroscopic System, and a Turn Coordinator (Gyroscopic System).
There are three basic kinds of instruments classified by the job they perform: flight instruments, engine instruments, and navigation instruments. There are also miscellaneous gauges and indicators that provide information that do not fall into these classifications, especially on large complex aircraft.
A Symbol Generator (SG) is the device that receives the data from the airframe sensors and serves as the television transmitting station by processing the data for appropriate viewing. Aircraft with a five-tube EFIS will typically have three Symbol Generators.
In an airliner, the cockpit is usually referred to as the flight deck, the term deriving from its use by the RAF for the separate, upper platform in large flying boats where the pilot and co-pilot sat. In the US and many other countries, however, the term cockpit is also used for airliners.
Today, modern gyroscopes come in three general varieties: mechanical gyroscopes, gas-bearing gyroscopes and optical gyroscopes. Mechanical and gas-bearing gyroscopes work on the principle of conservation of angular momentum to detect movement, though some use other principles.
