The JAHUMS ACTD technology insertion efforts capitalize on the availability of a commercial health and usage monitoring system (HUMS) that consists of an onboard processing unit, a ground based processor and server, and an enterprise database. A non-proprietary open systems specification for the system provides interface information to support the development of technologies by independent third party providers. Several technology modules are being developed in parallel with the initial fielding of the baseline system and consist of both hardware and software components that will be added to the onboard and ground based systems. It is anticipated that a modular open architecture, coupled with a complementary business architecture, will provide substantial opportunities for technology insertion in both military and commercial HUMS.","PeriodicalId":269139,"journal":{"name":"Gateway to the New Millennium. 18th Digital Avionics Systems Conference.

A viable set of requirements implies that each individual requirement is a necessary element in satisfying the stated goals and that the entire set of requirements, taken as a whole, is sufficient to satisfy the stated goals. Unfortunately, it is the author's experience that during project formulation phases' many of the Systems Engineering customers do not conduct a rigorous analysis of the goals and objectives that drive the system requirements. As a result, the Systems Engineer is often provided with requirements that are vague, incomplete, and internally inconsistent. To complicate matters, most systems development methodologies assume that the customer provides unambiguous, comprehensive and concise requirements. This paper describes the specific steps of a Goals Analysis process applied by Systems Engineers at the NASA Langley Research Center during the formulation of requirements for research projects. The objective of Goals Analysis is to identify and explore all of the influencing factors that ultimately drive the system's requirements.","PeriodicalId":269139,"journal":{"name":"Gateway to the New Millennium. 18th Digital Avionics Systems Conference.

At San Francisco International Airport (SFO), for example, runways 28L and 28R are separated by 750 feet. Use of visual flight rules to runways 28L and 28R allows a typical arrival throughput of approximately 60 landings per hour. During instrument meteorological conditions, a single runway is used, and the arrival throughput is reduced to 30 landings per hour. This loss of throughput can result in significant delays for aircraft intending to arrive at SFO, and can cause backups that have national airspace system (NAS) repercussions as well. To address this loss of throughput during instrument conditions, United Airlines has proposed a procedure for a dependent approach into San Francisco International Airport (SFO). Aircraft would be paired for approach in close longitudinal proximity. Longitudinal separation between paired aircraft would be established and maintained by the use of Automatic Dependent Surveillance Broadcast (ADS-B) combined with a Cockpit Display of Traffic Information (CDTI). The in-trail aircraft of a pair would be required to maintain specific longitudinal separations through the approach for both wake avoidance and collision avoidance purposes. Longitudinal separation between aircraft pairs would be based on standard instrument flight rule separations.","PeriodicalId":269139,"journal":{"name":"Gateway to the New Millennium. 18th Digital Avionics Systems Conference.

These expectations form the basis for what can called the operator's \"mental model\" of the system. An \"automation surprise\" is said to occur when the automation behaves in a manner different from what the operator expects. A requirement for a properly functioning human-machine system is that the human operator have good situation awareness. A key component of an operator's situation awareness is knowing how the machine will behave in the near future. Automation surprises are situations in which this system requirement has failed. In this paper, the modeling language-Murphi-is used to model and analyze an automation surprise in which a flight crew, using the autopilot, climbs above their cleared altitude during a full mission flight simulation. Murphi is a system description language and model checker developed by software engineers to formally evaluate behavioral requirements for concurrent software processes A rule-based model of the autopilot system and the pilot was developed. Murphi was then used to automatically check the validity of the above requirement for a model of the pilot-autopilot-aircraft system. The requirement failed for the same sequence of human and machine events that were recorded in the altitude bust incident. The Murphi model was then modified to explore possible procedural and mode logic fixes to reduce the likelihood of this type of breakdown in the human-machine system.","PeriodicalId":269139,"journal":{"name":"Gateway to the New Millennium. 18th Digital Avionics Systems Conference.
