Decision-aid systems, likely to appear in future aircraft generations, could play a central role in the cockpit thanks to the broad spectrum of functionalities and decision support facilities they will offer to the crew. As part of such systems, the exploratory FINDER mock-up is a knowledge-based system (KBS) designed to help crew members continually optimize their flight plan by suggesting solutions considering exhaustive information related to flight context, either on pilot request or upon external information occurrence. The successful evaluation by AIR FRANCE pilots of that first mock-up dedicated to diversion procedure on pilot request has led to the current development of an enhanced system with nominal Enroute operations and real-time capabilities. Nominal Enroute operations concern the optimization with respect to an evolutive constraining or favouring environment (due to weather, traffic or regulated areas, ETOPS constraints). This study paves the way for a future Flight Assistant System concept which is already under investigation and may take place in SEXTANT Avionique's future development steps  相似文献

未来民机驾驶舱将广泛采用触控技术,但目前尚未形成针对民机驾驶舱显示触控系统的人机工效评价体系与评价方法。针对上述问题,首先梳理民机驾驶舱显示触控系统相关的现行标准与规范,结合适航规章中人为因素考察项,提出民机驾驶舱显示触控系统人机工效评价指标体系。其次,考虑到评价指标的模糊性与灰色性,基于灰色关联分析,对传统模糊层次综合评价算法从数据集结处理和指标权重确定两个方向进行改进,通过构造专家信度系数修正秩次矩阵,实现专家认知特性的定量描述,建立民机驾驶舱显示触控系统人机工效综合评价模型。最后,结合ACROSS项目下的民机驾驶舱显示触控系统人机工效评价试验案例,分析驾驶舱显示触控系统配置策略对系统人机工效的影响,验证了评价体系与评价方法的适用性和合理性。  相似文献

The multifunction display (MFD) developed for use as the primary cockpit display system on the US Air Force C-17A military air transport is described. The 6-in by 6-in color cathode ray tube (CRT) display features a self-contained 1750 processor and vector generator capable of processing MIL-STD-1553B aircraft data and raster video into any of 10 formats as selected by the pilot or copilot. The MFD can display stroke, raster, or hybrid formats in 16 colors. Raster images are driven by sensor inputs with an RS-170 or RS-343 interface. The CRT uses a taut mask delta gun design and provides the best available brightness and line-width performance. The display features small size, low weight, low power, standard interface, and adaptable software. Reconfigurability in the aircraft is enhanced by using four identical cockpit displays  相似文献

A study was conducted to evaluate training and displays for the vertical guidance system of a modern glass cockpit airliner. The experiment consisted of a complete flight performed in a fixed-base simulator with airline pilots. Three groups were used to evaluate a new flight mode annunciator display and vertical navigation training. Results showed improved pilot performance with training and significant improvements with the training and the Guidance-Flight Mode Annunciator. Using actual behavior of the avionics to design pilot training and FMA is feasible and yields better pilot performance.  相似文献

A cockpit revolution is in the making. Many of the much ballyhooed, much promised, but little delivered technologies of the 70's and 80's will finally come of age in the 90's just in time to complement the data explosion coming from sensor and processing advances. Technologies such as helmet systems, large flat panel displays, speech recognition, color graphics, decision aiding and stereopsis, are simultaneously reaching technology maturities that promise big payoffs for the third generation cockpit and beyond. The first generation cockpit used round dials to help the pilot keep the airplane flying right side up. The second generation cockpits used multifunction displays and the HUD to interface the pilot with sensors and weapons. What might the third generation cockpit look like? How might it integrate many of these technologies to simplify the pilot's life and most of all: what is the payoff? This paper examines tactical cockpit problems, the technologies needed to solve them and recommend three generations of solutions  相似文献

The avionics of current-day aircraft is termed as modular integrated full glass cockpit. Unlike lots of dials and gauges, the pilot will interact with Multi-Function Displays (MYD). This means that the systems are coupled with multi-function displays, communication and navigation radios with control units, multi-mode interactive instruments for control and navigation, recording and fault management systems, airframes and health monitoring diagnostic capabilities. Pilot Vehicle Interface (PVI) is an important measure of good avionics and cockpit layout, which implies the optimization of man-machine interface, enhancement of the economy, and safety of flight operations. This presents the avionics architecture of a 14-seat Light Transport Aircraft (LTA) for general aviation, which has multi-role commuter capabilities. LTA is a twin turbo-prop, multi-role aircraft, with air taxi and commuter services as its primary roles. The avionics is built on the digital communication mode for both command and control with current requirements of TCAS, digital Autopilot, and AMLCD multi-purpose glass displays. The LTA Avionics suite is grouped into six major groups based on functionality: Display System, Communication System, Navigation System, Recording System, Radar System, and Engine instruments and other cockpit displays. This paper also covers details about the extensive tests carried out to prove the avionics design in terms of functionality, inter-operability, interference, and compatibility. Various practical integration and flight-test issues, methodologies, and details of the scenarios is presented herein.  相似文献

The goal of advanced cockpit display systems is to present large amounts of information quickly and in an understandable format, enabling the aviator to improve mission performance. Current front-line cockpit display systems utilize low-resolution analog video to present two-dimensional (2-D) images on many separate displays. The future cockpit will be capable of integrating large picture digital video with three-dimensional (3-D) and 2-D color images. This system will be capable of rendering icons, maps, and world-views. It will be compatible with head mounted displays and multiple large displays to improve war-planning and combat aviator situational awareness. We are developing a massively parallel 3-D renderer which will be capable of updating 500,000 3-D triangles per second with shading, lighting, transparency, texture mapping, and hidden surface removal. The renderer design employs a massively parallel architecture with 1,024 ALUs per chip to display one million anti-aliased vectors per second. Current high end workstations are capable of these display goals, but fall far short of military reliability, size, and power requirements. The rendering system will be small enough to fit on one board, extensible to dual-seat configuration, and capable of up to eight windows per display channel  相似文献

Over 8,000 altitude deviations are reported to NASA's Aviation Safety Reporting System each year. This is almost one an hour. The narratives of pilot incidents relate how errors made in the automation-assisted altitude change task are caused by the difficulty pilots are having interacting with automatic systems. This paper discusses the impact of increased automation in glass-cockpit airliners on the altitude deviations reported by pilots. By observing the way information is processed by the cockpit system, the author suggests that the philosophies of design and training need to change in order to facilitate, not debilitate, the aircrew  相似文献

Aircraft cockpit display interface (CDI) is one of the most important human-machine interfaces for information perceiving. During the process of aircraft design, situation awareness (SA) is frequently considered to improve the design, as the CDI must provide enough SA for the pilot to maintain the flight safety. In order to study the SA in the pilot-aircraft system, a cockpit flight simulation environment is built up, which includes a virtual instrument panel, a flight visual display and the corresponding control system. Based on the simulation environment, a human-in-the-loop experiment is designed to measure the SA by the situation awareness global assessment technique (SAGAT). Through the experiment, the SA degrees and heart rate (HR) data of the subjects are obtained, and the SA levels under different CDI designs are analyzed. The results show that analyzing the SA can serve as an objective way to evaluate the design of CDI, which could be proved from the consistent HR data. With this method, evaluations of the CDI design are performed in the experimental flight simulation environment, and optimizations could be guided through the analysis.  相似文献
