The symbol generator can go by other names, such as display processing computer, display electronics unit, etc. The symbol generator does more than generate symbols. It has (at the least) monitoring facilities, a graphics generator and a display driver. [2] Inputs from sensors and controls arrive via data buses, and are checked for validity.
In aviation, above aerodrome level (AAL), or above aerodrome elevation (AAE), denotes that an altitude is given above the nearest aerodrome or airport. AAIB Air Accidents Investigation Branch: United Kingdom AAIM Aircraft Autonomous Integrity Monitoring AAO Assumed adverse obstacle AAS Airport advisory service [1] AC Advisory circular [2]
Technical standards exist to provide glossaries of abbreviations, acronyms, and symbols that may be found on engineering drawings. Many corporations have such standards, which define some terms and symbols specific to them; on the national and international level, ASME standard Y14.38 [1] is one of the standards. Australia utilises the ...
On modern aircraft, the CSD is often combined with a generator into a single unit known as an integrated drive generator (IDG). Control engineering – or control systems engineering, is an engineering discipline that applies automatic control theory to design systems with desired behaviors in control environments. [48]
A diagram which shows the interconnection of process equipment and the instrumentation used to control the process. In the process industry, a standard set of symbols is used to prepare drawings of processes. The instrument symbols used in these drawings are generally based on International Society of Automation (ISA) Standard S5.1
The symbols are designed to enhance NATO's joint interoperability by providing a standard set of common symbols. APP-6 constituted a single system of joint military symbology for land, air, space and sea-based formations and units, which can be displayed for either automated map display systems or for manual map marking.
A blank square indicates that there is no interface between the respective entities. Data flows clockwise between entities (i.e., the symbol F1 → F2, in Figure 4, indicates data flowing from function F1 to function F2; the symbol F2 → F1 indicates the feedback). That which passes across the interface is defined in the appropriate squares.
Avionics engineering is similar, but deals with the electronics side of aerospace engineering. "Aeronautical engineering" was the original term for the field. As flight technology advanced to include vehicles operating in outer space, the broader term "aerospace engineering" has come into use. [4] Aerospace engineering, particularly the ...
