	Avionics software - Wikipedia, the free encyclopedia
		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 the development process is required by law and is optimized for safety.
		The reliability of the software running in airborne vehicles (civil or military) is shown by the fact that most air borne accidents occur due to manual errors.

		Software engineering is the technologies and practices that are used to create computer software while improving productivity and quality.
		Software engineering is much younger than civil engineering and electronic engineering and much older than space engineering[?] and biological engineering.
		Software engineering arose out of the so called software crisis of the 1960s, 1970s, and 1980s, when many software projects had bad endings.

		Avionics software is embedded software with legally-mandated safety and reliability concerns.
		Avionic software is viewed as a rather nasty and unpredictable part of the avionics.
		One of the major differences between avionics and commercial electronics is that everything on an aircraft can usually be semi-automatically tested in the time it takes to turn around the aircraft at an airport.

	Avionics - Wikipedia, the free encyclopedia
		Avionics include communications and navigation systems, autopilots, and electronic flight management systems (FMS).
		Since the aircraft's time is precious, most avionics are designed as "line replaceable units." In the electronic bay these are literally fl boxes, in standard sizes, with standard trays, and standard connectors for power and cooling.
		Avionics have changed significantly with the advent of the GPS receiver and "glass cockpit" display systems.

	DO-178B - Wikipedia, the free encyclopedia
		The FAA accepts use of DO-178B as a means of certifying software in avionics.
		The required level is determined from the safety assessment process and hazard analysis by examining the effects of a failure condition in the system.
		Analysis of all code and traceability from tests and results to all requirements is typically required (depending on software level).

	Boeing delivers updated F-22 avionics software; final board requirement met (Site not responding. Last check: 2007-10-13)
		In conjunction with the delivery, Boeing completed a number of modifications to the test bed aircraft and to the CNI and EW systems, including missile-launch detectors, which were installed in the aircraft's cabin, on its "sensor wing" and on a special pod attached to the underside of the fuselage.
		The FTB, a modified Boeing 757 jet, is helping reduce avionics development costs, risks and future F-22 flight test hours by enabling extensive in-flight testing, evaluation and troubleshooting before full avionics are ever installed and flown on the Raptor.
		Previous modifications to the test bed include installation of an F-22 forward fuselage section to the nose of the plane, installation of a sensor wing on the plane's crown and installation of a simulated F-22 cockpit in the test bed cabin.

	Software Dioxide: Avionics Software Quality (Site not responding. Last check: 2007-10-13)
		Embedded software in airborne equipment must follow stringent and rigorous process guidelines throughout the development life cycle.
		The standard that enforces this, referred to as DO-178B, ensures that every line of code in the airborne embedded system is verified and tested and that requirements are accurate, consistent, verifiable, conforming to standards and compatible with the target computer, down to the object code.
		It defines the embedded software life cycle processes, the outputs expected as well as what should go into each output or deliverable.

	STSC CrossTalk - Lessons Learned From Another Failed Software Contract - Sep 2003 (Site not responding. Last check: 2007-10-13)
		A software component is a white box when (1) modification is required to meet system requirements, (2) the component reliability is in question, or (3) the knowledge of the component and its documentation are inadequate for the application.
		The baseline software was not being developed with reuse as an attribute, nor could its developer have been expected to be more than minimally cooperative with the adaptation of that software to the new requirements.
		Since the software estimate totally ignored these issues, as well as the experience issues, the logical assessment is they assumed the volatility of the development environment was also no problem.

		The Capability Maturity Model (CMM) of the Software Engineering Institute (SEI) describes the maturity of software development organisations on a scale of 1 to 5.
		The CMM has been used extensively for avionics software and for government projects.
		More commercially successful methodologies have focused not on the capability of the organization to produce software to satisfy some other organization or a collectively-produced specification, but on the capability of organizations to satisfy specific end user "use cases".

	AVIONICS SYSTEMS
		Almost all electrical and electronic equipment is installed in three areas of the orbiter: the flight deck, the three avionics equipment bays in the middeck of the orbiter crew compartment and the three avionics equipment bays in the orbiter aft fuselage.
		The flight deck of the orbiter crew compartment is the center of avionics activity, both in flight and on the ground.
		One of the system software responsibilities is to manage the GPC input and output operations, which includes assigning computers as commanders and listeners on the data buses and exercising the logic involved in sending commands to these data buses at specified rates and upon request from the applications software.

		It is known that one of the side effects of merging multiple software applications using existing software development tools is unwanted dependencies between the software applications, such as the propagation of faults from one failing software application to others.
		In addition, each application executive and its associated software applications are temporally isolated from other application executives and their associated software applications by enforcing usage restrictions on the CPU and other system resources based on a pre- computed static execution timetable.
		The software applications 321, interface library 312, and timer interrupt services routines 501 (shown in Figure 5) associated with each application executive 311 also consist of instructions that are executed on central processing unit 201 and are stored in the same application partition 500 (shown in Figure 5) as the associated application executive 311.

	Avionics Software Engineering Division Moves to Systems Engineering Department as Part of BPR (Site not responding. Last check: 2007-10-13)
		The move of the Avionics Software Engineering Division from the Avionics Department (code 4.5) to the Systems Engineering Department (code 4.1), in which all branches and branch heads initially remain unchanged, is a recog- nition of how integral software is to all of today's systems—not just avionics.
		Additionally, because software is so pervasive and the cost to change software increases exponentially over time, the earlier software professionals are involved on an IPT, the better.
		Another attribute of the Software Center of Excellence will be the scalability and portabil- ity of its workforce; the ability to proactively shift employees to the right team to better meet the changing needs of programs and projects, and to assure continuity of workload for all Division employees.

		Avionics software developers today are continually challenged to cut costs and reduce time to market, without compromising the safety of their application.
		It is important to note that although a software component may have been previously included in other systems that were certified under DO-178B, it does not necessarily follow that the software component will be certifiable in the new system.
		For software verification process activities, independence is achieved when a person(s) other than the developer of the item being verified performs the verification activity; a tool(s) may be used to achieve equivalence to the human verification activity.
