The main difference between avionic software and conventional embedded software is that the development process is required by law and is optimized for safety. It is claimed 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 .
Aircraft recognition generally depends on learning the external appearance of the aircraft, both friendly and hostile, most likely to be encountered. Techniques used to teach this information have included scale models , printed silhouette charts, slide projectors , computer aided instruction and even specially-printed playing cards .
The FMS can be summarised as being a dual system consisting of the Flight Management Computer (FMC), CDU and a cross talk bus. The modern FMS was introduced on the Boeing 767, though earlier navigation computers did exist. [1] Now, systems similar to FMS exist on aircraft as small as the Cessna 182. In its evolution an FMS has had many ...
Additionally, it automatically tracks primary and secondary surveillance targets and provides aircraft position information to the enhanced traffic management system (ETMS). Finally, it also detects unsafe proximities between tracked aircraft pairs and provides a warning if tracked aircraft are detected at a dangerously low altitude.
Automatic target recognition (ATR) is the ability for an algorithm or device to recognize targets or other objects based on data obtained from sensors. Target recognition was initially done by using an audible representation of the received signal, where a trained operator who would decipher that sound to classify the target illuminated by the ...
This software may be written manually or with the help of COTS tools such as GL Studio, [2] VAPS, [3] VAPS XT [4] or SCADE Display. [5] Standards such as ARINC 661 specify the integration of the CDS at the software level with the aircraft system applications (called User Applications or UA).
Abstract representation of a Fly-By-Wire flight system. A flight control computer (FCC) is a primary component of the avionics system found in fly-by-wire aircraft. It is a specialized computer system that can create artificial flight characteristics and improve handling characteristics by automating a variety of in-flight tasks which reduce the workload on the cockpit flight crew.
IMA concept also allows the Application developers to focus on the Application layer, reducing the risk of faults in the lower-level software layers. As modules often share an extensive part of their hardware and lower-level software architecture, maintenance of the modules is easier than with previous specific architectures.
