VDDS was developed early in the V-22 program to emulate real \"glass cockpit\" displays. It uses Commercial Off The Shelf (COTS) technology and is being maintained for the life of the V-22 aircraft. Our experience with VDDS has proven it to be an invaluable tool for risk reduction and life cycle support and has validated the product's potential for reducing avionics integration costs and risk on other military platforms. VDDS provides a windows-based simulation of five avionics display processors and the eight display surfaces that comprise the V-22 glass cockpit. The use of COTS technology significantly decreased program risk by allowing the prime contractor to use a functionally equivalent glass cockpit well in advance of integrating real display systems. This allowed early verification and validation of the V-22 mission-critical software and the various avionics display system requirements, thereby reducing risk to both the prime contractor and all display subcontractors. VDDS also supports quick updates to resolve issues in support of lab integration, software test, and on-aircraft integration test.","PeriodicalId":269139,"journal":{"name":"Gateway to the New Millennium. 18th Digital Avionics Systems Conference.

Although the FAA has recommended turbulence procedures, the surveys were designed to investigate what decisions they actually make in turbulence. A previous paper details the pilot survey results (Bass & Ernst-Fortin, 1999). This paper discusses the FA survey results, differences found between the two communities with regard to turbulence judgments and decision making, and suggested improvements.","PeriodicalId":269139,"journal":{"name":"Gateway to the New Millennium. 18th Digital Avionics Systems Conference.

The subjects addressed within this paper include: scope and methodology of the study, and the CBA results for the various implementation scenarios identified. The results include the differing levels of expected economic benefits for airport configurations and AGATE options which were foreseen. These economic results are then weighted based upon a high level risk analysis to address potential implementation issues associated with each scenario. Based on the weighted results a recommended set of actions are developed. The significance of this work is that it is one of the key inputs into Europe's decision making process as it applies to future A-SMGCS implementation plans and policies.","PeriodicalId":269139,"journal":{"name":"Gateway to the New Millennium. 18th Digital Avionics Systems Conference.

The avionics development included the design of an ultrasonic altimeter and mounting of a three-axis accelerometer. A small data logger based on a Motorola MC68332 processor was used to collect sensor data. A control program for the data logger was developed using the C programming language. The operation of the avionics package was validated through ground and flight testing. Concurrently with the development of the avionics package, a dynamic model of the helicopter was developed using aerodynamic parameterization and linear state-space modeling techniques. The Joint Army/Navy Rotorcraft Analysis and Design (JANRAD) computer program was utilized to obtain the stability and control derivatives. The fidelity of the simulation model was verified by comparing the simulation responses with data collected from the avionics sensors during flight tests.","PeriodicalId":269139,"journal":{"name":"Gateway to the New Millennium. 18th Digital Avionics Systems Conference.

This undesired coupling of electromagnetic energy can cause system performance degradation. Bench-level EMI tests are required by both commercial and military customers to verify that electronic control systems are sufficiently hardened against this EME. This paper will illustrate an example of a high-power (>1000 V/m) radiated susceptibility test on an aircraft full-authority digital electronic control (FADEC) which was performed in a reverberation chamber. The reverberation chamber was chosen for this test because it offers several advantages over the traditional anechoic chamber, such as the ability to generate high field strengths more efficiently and a much quicker test time (making it more economical). The reverberation chamber also provides a more thorough test, with less uncertainty than anechoic or other facility types. Since a FADEC operating closed-loop is a fairly complex system, the methods described in this paper can be considered to be a useful model of successful, effective radiated susceptibility testing for electronic systems.","PeriodicalId":269139,"journal":{"name":"Gateway to the New Millennium. 18th Digital Avionics Systems Conference.
