Moreover, in many cases, if proper design, materials, and packaging approaches, and assembly and quality assurance procedures are utilized, both MCM-L/COB and silicon microbench passive alignment technologies may actually enable design ad manufacturing of low cost avionics optoelectronics modules. Silicon microbench passive alignment packaging technology has been demonstrated for LED, PIN photodiode, VCSEL and edge emitting laser diode packaging. Although MCM-L/COB and silicon microbench passive alignment technologies have been shown to be ruggedizable for the avionics environment, additional reliability testing and infrastructure development work is required before they are implemented in real avionics systems. VCSELs and edge-emitting diode lasers can be reliably used in systems with excursions to high temperature avionics environments) if the total time-at-high temperature is kept modest. Simple temperature measuring circuits and laser diode drive current monitoring circuits for onboard diagnostics and maintenance could be implemented to ensure reliable operations of high-speed laser-based transmitters in the avionics environment.","PeriodicalId":269139,"journal":{"name":"Gateway to the New Millennium. 18th Digital Avionics Systems Conference.

The merit of aircraft airworthiness management has proven extremely successful for the government fleet for more than a decade. The inspection and information management technologies are particularly effective for rapid fault detection and fault assessment when hidden structural corrosion, hidden structural cracks, internal engine blade cracks, or composite disbonding occurs. In the future, advanced NDI will be the only means of finding faults when advanced or designer materials are used. Analogously, the process can be likened to a doctor's administration of an MRI (and other tests) to each of his patients and then following through with long-term health management plans for the entire patient group.","PeriodicalId":269139,"journal":{"name":"Gateway to the New Millennium. 18th Digital Avionics Systems Conference.

Results indicated that use of a moving-map display was superior to either a tabular, text-only display or a text display with an additional orienting symbol. In addition, in contrast to an earlier study (Williams, 1999), pilots performed better using a north-up map than when using a track-up map. Discussion of the results focuses on recommendations for moving-map displays and the display requirements for support of the nearest-airport function within a navigational display in particular.","PeriodicalId":269139,"journal":{"name":"Gateway to the New Millennium. 18th Digital Avionics Systems Conference.

These legacy aircraft currently cool avionics and electronics with air as the coolant medium. The next generation of electronics will be densely packaged and will require liquid cooling, low coolant temperatures, and increased cooling capacities. Numerous advanced efforts have demonstrated that heat pump cooling systems offer a cost-effective solution that avoids the redesign of avionics modules or aircraft cooling systems. This paper will describe the design, development, and integration of an electrically-driven vapor cycle heat pump and its integration into the F-16 aircraft. This is an example of augmenting (versus redesigning) existing aircraft cooling systems, which then can provide liquid cooling for retrofit avionics.","PeriodicalId":269139,"journal":{"name":"Gateway to the New Millennium. 18th Digital Avionics Systems Conference.

The CAA program was started in 1996 as a method to gain valuable operational benefits from the emerging ADS-B technology. Three major CAA member airlines (UPS, FedEx, and Airborne Express) formed a technical steering committee to explore bringing an ADS-B system to reality. The system was to be STC certified for use in revenue service for the three airlines. With the FAA Safe Flight 21 program consisting of the CAA larger aircraft systems development and the Capstone smaller aircraft systems development, ADS-B is rapidly maturing into a valuable element of the new National Airspace System.","PeriodicalId":269139,"journal":{"name":"Gateway to the New Millennium. 18th Digital Avionics Systems Conference.

This paper describes a mechanism to implement OOP in Ada-83. Ada-83 is well suited for object based designs. Implementing the critical OOP features of inheritance and polymorphism in Ada-83 allows a programmer to move beyond an object-oriented design to an object design that utilizes object-oriented programming. By taking advantage of the strengths of both Ada-83 and OOP, software systems that are reliable, resilient to change, and easy to maintain can be developed. This paper provides details on the mechanism used to implement inheritance and polymorphism in Ada-83. This mechanism was developed for real-time applications that could not use Ada's tasking mechanism or dynamic memory allocation. Ada source code examples are provided to illustrate this OOP technique.","PeriodicalId":269139,"journal":{"name":"Gateway to the New Millennium. 18th Digital Avionics Systems Conference.

Digital map requirements for both fixed and rotary wing platforms were combined with the results from human factors studies to arrive at the desired capabilities that shaped the requirements for the TAMMAC program. The resultant system offers a significant improvement in aircrew situational awareness, particularly during nap of the Earth (NOE) flight and other high crew workload flight regimes. The baseline capabilities of the system will, in themselves, allow users to tailor the digital map operation to suit the needs of their particular missions. Considerable thought has already been given to identifying and shaping the growth capabilities described for the TAMMAC system. However, a methodical study, including flight crew interaction and human factors activities, should be undertaken to guide the platforms in deciding how to manage the considerable growth capabilities offered by the system.","PeriodicalId":269139,"journal":{"name":"Gateway to the New Millennium. 18th Digital Avionics Systems Conference.

The design uses commercial off-the-shelf (COTS) software components as much as possible, to reduce cost and software development time. The features of the IDS design that provide radiation hardness and fault tolerance are described. Implementation of software to meet the functional requirements is accomplished using a relatively small number of prioritized real-time tasks. A commercial real-time operating system kernel manages and supports these tasks. Inter-task communication is described, as are the software test and validation methods. The paper shows how custom ground support equipment was developed to facilitate software development and testing. Reliable communications between the IDS and the FUSE spacecraft bus are accomplished using a MIL-STD-1553B bus that has an imposed, deterministic real-time protocol. Similarly, communication between the IDS and the other instrument subsystems uses a second MIL-STD-1553B bus that has its own time division multiplex real-time protocol. The design of these real-time protocols is described, with particular attention to reliability and testability.","PeriodicalId":269139,"journal":{"name":"Gateway to the New Millennium. 18th Digital Avionics Systems Conference.
