In the last decade, we have seen several emerging technologies that will potentially have a great impact in complex systems. These new technologies are expected to cause a disruptive impact not only in the products but also in to the tools used across the whole product life cycle. For this reason, is imperative to perform a critical review of the current systems engineering tooling ecosystem. This assessment should also map the open research problems that could prevent the complete integration of the new technologies into the systems engineering framework. This paper proposes a new architecture for a system engineering environment to operate in large scale projects. The objective of this research is twofold: it will first identify the capabilities for the next generation platform, and secondly, it will evaluate how artificial intelligence applications can be integrated in compliance with DO-330. The concept developed by this research will drive tool design recommendations enabling the use of artificial intelligence driven applications in a systems engineering tooling ecosystem.","PeriodicalId":112045,"journal":{"name":"2020 AIAA/IEEE 39th Digital Avionics Systems Conference (DASC)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-10-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129378879","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}

Shi, Kaiquan Cai, Zhaoxuan Liu, Lanchenhui Yu","doi":"10.1109/DASC50938.2020.9256477","DOIUrl":"https://doi.org/10.1109/DASC50938.2020.9256477","url":null,"abstract":"Recently, with the rapid development of related avionics, Unmanned Aircraft Systems (UAS) have been widely used in various fields. The current segregated operations cannot meet their increasing demand and it is expected that UAS could operate in the integrated airspace with manned aircraft. However, full integration of UAS into civil airspace is confronted with the safety challenge because their Detect and Avoid (DAA) ability is not equivalent with that of manned aircraft. As the number of aircraft grows in the shared airspace, the possibility of flight conflicts will inevitably increase. In order to ensure the safe operation of various types of aircraft, a distributed Conflict Detection and Resolution (CD&R) method for integrated operation is proposed in this paper. First, a dynamic protect zone based on time threshold in the presence of uncertainty is designed to obtain efficient separation criteria. Based on the established protect zone, the Closest Point of Approach (CPA) strategy is employed to detect potential conflicts. Additionally, two conflict risk ranking mechanisms are specifically introduced to guarantee the efficiency of subsequent multi-aircraft conflict resolution. Finally, the mixed integer programming models have been built to minimize the conflict-free trajectory deviation via the Velocity Obstacle (VO) method. Numerical results have shown the superior performance of proposed method in different scenarios.","PeriodicalId":112045,"journal":{"name":"2020 AIAA/IEEE 39th Digital Avionics Systems Conference (DASC)","volume":"38 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-10-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133685419","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}

The directionality of acoustic waves has also been long used for localization by human beings. The term ‘echolocation’ was coined by Donald R. Griffin, where he discusses ship captains exploiting sound to ascertain the ship's surroundings and avoid obstacles in low-visibility environments. Acoustic sensors can provide a low-cost, size, weight, and power (C-SWaP) navigation solution, which is scalable and robust. Moreover, acoustic sensors have the capability to provide high-resolution spatial information at short distance range. This paper presents a novel acoustic positioning and navigation system for a micro aerial vehicle. Flight tests are performed to evaluate the system, where the performance of the acoustic system is compared with a motion capture system.","PeriodicalId":112045,"journal":{"name":"2020 AIAA/IEEE 39th Digital Avionics Systems Conference (DASC)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-10-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132452797","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}

Damage analysis on the surface of the mock space module is performed in real-time using video from each free-flyer. Three-dimensional modeling is deployed offline to supplement and improve damage detection.

Some are required due to system needs (i.e. to connect sensors and actuators) but some are part of the design of the avionics platform itself, like field buses and networks. While networks are well established, field buses often still use classic technology like ARINC 429. In this publication, a method is proposed that allows the avionics platform designer to compare field bus technologies, optimise the field bus networks and integrate this optimisation into an overall avionics platform optimisation. This is realised through modelling the architecture, network and signals in a formal way and formulating an combinatorial optimisation problem out of it. Off-the-shelf solvers are used to solve the resulting binary program using a Branch-and-Cut approach and obtain optimal field bus architectures for the constraints given.","PeriodicalId":112045,"journal":{"name":"2020 AIAA/IEEE 39th Digital Avionics Systems Conference (DASC)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-10-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115579763","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}

Schuetz","doi":"10.1109/DASC50938.2020.9256474","DOIUrl":"https://doi.org/10.1109/DASC50938.2020.9256474","url":null,"abstract":"A reduction of delay costs can be achieved through more adaptable flight planning, which hinges on accurate prediction of delays. In order to counteract the expected delay of flights, air traffic control may adapt flight plans through slot swapping, opening another runway, or changing the runway configuration, for example. Environmental conditions and external events such as runway and airspace closures may render a flight plan obsolete, which must be taken into account when aiming to reduce delay. Air traffic control must recognize changes in the environment and external events such as runway and airspace closures as early as possible in order to adapt flight plans accordingly and avoid delays. Current systems employed by air traffic control do not sufficiently leverage the multitude of available data for the detection of upcoming congestion and, consequently, flight delays. Therefore, flight plans are not adapted fast enough in air traffic scenarios with potentially high delay. In this paper, we aim to predict the risk class of an air traffic scenario based on the expected cost of the delays, and considering information about environmental conditions and external events. In particular, we present a random forest classifier for Atlanta International Airport, which achieves an accuracy of 82.5% for the highest and thus most important risk classes. The development of similar classifiers for other airports may help air traffic control to more accurately predict scenarios with high congestion, and counteract accordingly in the future.","PeriodicalId":112045,"journal":{"name":"2020 AIAA/IEEE 39th Digital Avionics Systems Conference (DASC)","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-10-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124067514","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}

The development of safety-critical system functions is troublesome and time-consuming. Most of the effort is spent on the development and verification of functions such as redundancy management or master/slave management to provide a fault-tolerant platform behavior. The SMW provides an efficient development method for platform management as a middleware used for safety-critical system functions on IMA. It is based on a knowledge-based toolchain, which automatically derives the instance of the platform management middleware from a manually designed high-level system architecture model. In addition to the platform management software, the required design artifacts and verification artifacts are automatically generated. Since the SMW approach supports the software development process with highly automated process activities, it is investigated to what extent the SMW approach reduces the development effort. Therefore, a detailed assessment framework is developed, which covers and evaluates its impact on development phases. Hence, four evaluation views are defined according to the development process, project management process, and the qualification process. The emphasis of this paper is on the so-called project view. Thereby the benefit of the SMW can be identified versus the conventional method. In order to be able to make a quantitative assessment, a set of criteria was defined. For each criterion, a figure of merit is given to quantify the impact. It allows the comparison of different development approaches, e.g., the SMW approach against the conventional IMA development approach. The assessment framework with the project view is applied to evaluate the SMW approach based on the experiences of a high-lift system development. Finally, the efficiency of the SMW is quantified and presented to estimate the approximate profit for the user.","PeriodicalId":112045,"journal":{"name":"2020 AIAA/IEEE 39th Digital Avionics Systems Conference (DASC)","volume":"29 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-10-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125865020","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}

However, increasing departure capacity at airports with narrow departure corridors remains challenging as implementations of additional departure paths and the current requirement for immediate divergence may markedly change an airport's noise footprint. This paper explores options for capacity-enhancing application of divergence-based initial spacing without requiring aircraft to diverge immediately after departure. It presents the analysis approach taken to characterize departure performance of aircraft observed in actual operations and the simulation model developed to estimate collision risk. The results indicate that the proposed operations meet target level of safety requirements for aircraft on PBN procedures that diverge within 10 miles after departure and suggest the feasibility of realizing departure capacity benefits while minimizing changes to the noise footprint of the operations.","PeriodicalId":112045,"journal":{"name":"2020 AIAA/IEEE 39th Digital Avionics Systems Conference (DASC)","volume":"18 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-10-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125896755","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}
