A highly efficient and safe air transport system relies on individually and system-wide optimized aircraft trajectories, where optimization functions typically focus on fuel, flight time minimization, transport quality, and environmental impact as major market drivers, or a combination thereof. Given these multiple criteria and the large-scale of the air transportation system, the trajectory building process for modern, efficient air transportation is highly computationally expensive, as its optimization relies on accurate aerodynamic and engine characteristics to be reflected in aircraft performance models. Moreover, environmental uncertainty sources should be statistically taken into consideration in the trajectory building process searching for individually optimized altitude, path and time conditions.This project aims to identify the benefits of using big data analysis and data driven methods for efficient trajectory and network design. So far used trajectory optimization tools are mostly analytically driven, model/search-based, and largely neglect historical trajectories as background. The rise of performance mass data gathering and storage capabilities, data mining over historical flight data is a novel candidate for robust and fast optimization. Given ICAO’s mandate on aircraft ADS-B (Automatic Dependent Surveillance - Broadcast) equipment installation by 2020, an aircraft tracking surveillance technology, increasing numbers of commercial aircraft are now being equipped with this capability. Throughout this project, we aim to better understand the suitability of applying big data-driven techniques for predicting single (local optimum) but also multiple (global optimum) aircraft trajectories. The biggest challenge in this approach is how to process these large quantities of data, more than 200,000 messages per second over a period of more than one year. Based on our initial joint research on compressed storage and indexing techniques, we intend to first search for efficient coupling of both partners’ strengths for single flight aircraft trajectory augmentation based on historic ADS-B track data in large entities and aircraft performance models for specific aircraft-engine combinations, then extending the optimization goal towards flow oriented objective functions reflecting particularly on small and large airline networks. Validation of the claimed model will be performed along significantly different styles and behavior in the Chinese and European airspace structure and market strategies guiding both airline network structures differently. Based on our research outcome, it will be possible to turn historical knowledge into scenario-based recommendations, which yield unprecedented accuracy and efficiency for the data-driven, goal-oriented design and optimization of aircraft trajectories.

高效和安全的航空运输系统依赖于单独和系统范围内优化的飞机轨迹，其中优化功能通常侧重于作为主要市场驱动因素的燃料、飞行时间最小化、运输质量和环境影响，或它们的组合。考虑到这些多重标准和航空运输系统的大规模，现代高效航空运输的轨迹建立过程的计算代价非常高，因为其优化依赖于准确的空气动力学和发动机特性，以反映在飞机性能模型中。此外，在寻找单独优化的高度、路径和时间条件的弹道建立过程中，应该在统计上考虑环境不确定性来源。本项目旨在确定使用大数据分析和数据驱动方法进行高效弹道和网络设计的好处。到目前为止，使用的轨迹优化工具大多是基于分析驱动的、基于模型/搜索的，并且在很大程度上忽略了作为背景的历史轨迹。随着性能海量数据收集和存储能力的提高，对历史飞行数据进行数据挖掘是一种新的稳健和快速优化的选择。鉴于国际民航组织的任务是在2020年前安装飞机ADS-B(自动相关监视-广播)设备，这是一种跟踪监视技术，越来越多的商用飞机现在正在配备这一能力。在整个项目中，我们的目标是更好地了解应用大数据驱动的技术预测单一(局部最优)和多个(全局最优)飞机轨迹的适用性。这种方法最大的挑战是如何处理这些海量数据，在一年多的时间里每秒超过20万条消息。基于我们对压缩存储和索引技术的初步联合研究，我们打算首先基于大型实体的历史ADS-B轨迹数据和特定飞机-发动机组合的飞机性能模型，寻找合作伙伴在单次飞行飞机轨迹增强方面的优势的有效结合，然后将优化目标扩展到面向流量的目标函数，特别是反映在小型和大型航空公司网络上。对声称的模型的验证将按照中国和欧洲空域结构中显著不同的风格和行为以及指导两家航空公司网络结构的不同市场战略进行。根据我们的研究成果，将有可能将历史知识转化为基于情景的建议，从而为以数据为驱动、以目标为导向的飞机轨迹设计和优化带来前所未有的准确性和效率。
