商用飞机机载情景感知信息系统的迭代设计

飞行员使用纸质文件和机载电子设备辅助来执行程序以确保飞行的安全性、有效性和舒适性。机载情景感知信息系统设计用以在正常、非正常以及紧急情况下提供飞行、系统、性能和导航4个方面的操作信息。系统内容是由3层信息结构超链接组织的:必须知道的信息或涉及安全的关键信息(级别1);次要信息(级别2);以及需要理解的信息(级别3)。提出不管是自动显示还是人工选择显示的随情景感知的信息,都应使飞行员更容易在正确的时机获得适当的操作内容。机载情景感知信息系统采用“人在环路(HITL)”模拟,并有多名专业飞行员在模拟机上对该系统进行了测试。第一批的数据结果表明,机载情景感知信息系统的操作信息访问是可用且有用的,并且具有纸质文件所没有的特性。 

Iterative Designs of Onboard Context-Sensitive Information System (OCSIS)for Commercial Aircrafts

Pilots use paper-based documentation and electronic systems to guide them following the procedures to ensure safety,efficiency and comfort on commercial aircrafts.The Onboard Context-Sensitive Information System (OC-SIS)is developed to provide operational information on flight,system,performance,and navigation in normal,abnormal and emergency situations.Its content is organized using a hyperlinked three-layer information structure:need-to-know or safety-critical information (Level 1);nice-to-know (Level 2);and need-to-be-understood (Level 3).The claim is that the use of contextual information facilitates access to appropriate operational content at the right time either automatically or on demand.OCSIS is tested using human-in-the-loop (HITL)simulations that involve professional pilots in the simulator. Preliminary results are encouraging because they show that OCSIS is useful for accessing operational information and pro-viding additional features that paper-based documents do not have.
