Some flexibility for real-time embedded software systems has been achieved recently through time and space partitioned (TSP) operating systems. TSP operating systems have been implemented through ARINC-653 architectures by a number of commercial vendors to support safety critical applications. However, for increased functionality and flexibility to support future battle space scenarios, aircraft needs to communicate over multiple networks while maintaining data separation and multiple levels of security (MLS). As a result, new MLS-capable real time operating systems referred to as multiple independent levels of security/safety (MILS) separation kernels are emerging and in the process of being certified. The ARINC-653 standard, which too is used by the new MILS kernel, allows for independently produced applications to run together on the same hardware and provide most of the capability necessary for isolating applications with different security levels. With MILS, functionality such as device drivers, files systems, and networks stacks are moved out of the RTOS and put into partitions, so the kernel can be affordably evaluated (using mathematical verification) and information flow, data isolation, periods processing, and damage limitation can be enforced. To better understand the impacts of separating device drivers from the kernel, Boeing moved the bulk of a Dy-4 Systems' MIL-STD-1553 device driver functionality out of a RTOS kernel and into an application partition. This paper details the design, decisions, effort, results, and lessons learned as a result of performing this activity under the Air Force Research Laboratory (AFRL) program in support of the CV-22. AFRL's objective was to gain insight and promote the development and application of commercial TSP operating systems for real-time embedded software systems","PeriodicalId":443824,"journal":{"name":"2006 ieee/aiaa 25TH Digital Avionics Systems Conference","volume":"132 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131406316","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This development has leveraged decades of work on improving terminal area operations, especially the arrival phase. With APS operations, the air traffic controller instructs the participating aircraft to achieve an assigned inter-arrival spacing interval at the runway threshold, relative to another aircraft. The flight crew then uses airborne automation to manage the aircraft's speed to achieve the goal. The spacing tool is designed to keep the speed within acceptable operational limits, promote system-wide stability, and meet the assigned goal. This reallocation of tasks with the controller issuing strategic goals and the flight crew managing the tactical achievement of those goals has been shown to be feasible through simulation and flight test. A precision of plusmn2-3 seconds is generally achievable. Simulations of long strings of arriving traffic show no signs of instabilities or compression waves. Subject pilots have rated the workload to be similar to current-day operations and eye-tracking data substantiate this result. This paper will present a high-level review of research results over the past seven years from a variety of tests and experiments. The results will focus on the precision and accuracy achievable, flow stability and some major sources of uncertainty. The paper also includes a summary of the flight crew's procedures and interface and a brief concept overview","PeriodicalId":443824,"journal":{"name":"2006 ieee/aiaa 25TH Digital Avionics Systems Conference","volume":"20 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-10-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115430643","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

TBO are envisioned to form the basis for both more strategic planning in the NGATS and for more tactical operations including separation management. The cornerstone of this concept is the establishment of a four-dimensional trajectory. The concept also calls for the use of a controlled time of arrival (CTA) to help manage the use of a specific system resource. A flight management system (FMS) onboard the aircraft has capabilities that may prove useful when operating under TBO. Such capabilities include required time of arrival (RTA) - the capability to \"self-deliver\" to a specified waypoint at a specified time. The RTA capability may be employed to implement a CTA. This paper presents an investigation into the FMS capabilities to meet an RTA and looks at the impact of using a lateral offset maneuver to address a tactical situation has on a flight's ability to meet an RTA. Several PC-based models of a Smiths Aerospace FMS/Boeing 737 aircraft were used during this investigation.

Based on the exchange of information between aircraft and ATC via data link, a trajectory based traffic management can take into account user preferred trajectories as well as make use of highly accurate prediction of aircraft movements. This contribution focuses on the airborne part - in particular on the 4D FMS functions for planning and flying various types of CDA approaches. The planning functions to compute approach profiles ranging from 2 degree (clean configuration) up to steep slopes (more than 5 degree) with early configuration and glide path intersection from above are presented. Furthermore, functions to compensate deviations due to inaccurately forecasted wind are described. These functions ensure flying the predicted flight path. The new CDA functionalities have been implemented in DLR's 4D capable advanced flight management system (AFMS) and intensively tested during various flight trials in the A330 full flight simulator in Berlin and with DLR's test aircraft ATTAS, a VFW 614 twin engine jet transport aircraft modified for research purposes.

A response to this is enhancing the runway utilization and throughput before investing on new runways or instruments. Runway throughput can be increased by reducing in-trail landing separation between aircraft, but the consequence may be an increase in the chance of a severe wake vortex encounter or a simultaneous runway occupancy (or go-around). Current instrument flight rule (IFR) standards provide fixed separation minima for given pairs of wake vortex weight classes of aircraft. In practice, the observed separation is a random variable and fluctuates near or above the specified minimum. In this paper, we propose a framework for statistical separation standards that specifies not only a lower bound for the separation but also a standard for the target value and the variance of the process. We address the question of what a more efficient separation standard is in order to control the risk in the approach process. We also consider whether separation variability may be reduced by employing such standards, i.e. more detailed standards that take the \"realized variability\" into account. Analytical results of this study suggest that (under specific assumptions) throughput can be increased to some extent without degrading safety for the given facilities, infrastructure, and weather condition. The arguments and concepts are illustrated with statistical observations from Detroit airport (DTW)","PeriodicalId":443824,"journal":{"name":"2006 ieee/aiaa 25TH Digital Avionics Systems Conference","volume":"148 ","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134162030","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
