摘要

美国联邦航空管理局(FAA)座舱气象技术(WTIC)项目赞助了一项操作演示,为偏远和海洋地区的商业航班提供基于卫星的气象信息。这项工作被称为远程海洋气象信息操作(ROMIO)示范。为此,国家大气研究中心(NCAR)开发了两种天气产品:1)云顶高度(CTH)和2)对流诊断海洋(CDO)。CTH产品显示FL320、FL340、FL360、FL380和FL400飞行高度的云顶轮廓。CDO产品显示了风暴上升气流、闪电和超冲顶相关的危险,并分为中、高、严重和极端四个强度等级。在本文中,我们通过调查分析来研究ROMIO演示的潜在效益,以衡量飞行员在航路对流天气规避过程中的接受程度和ROMIO辅助行为。我们创建了一个飞行后的飞行员调查,对使用ROMIO应用程序的好处进行定性测量,并评估用户对新的机载信息技术的接受程度。问卷中的问题主要分为5类:1)决策、2)工作量、3)态势感知、4)效率和5)信息质量。我们采用Wilcoxon 's秩和检验来分析李克特量表反应。该研究包括105份试点调查回复。这项研究的结果提高了我们从飞行员的角度对新的机载天气信息技术的潜在好处的理解,并使我们能够确定进一步改进ROMIO演示的潜在领域。

Operational Benefits of Remote Oceanic Meteorology Information Operational (Romio) Demonstration: A Survey-Based Analysis
The Federal Aviation Administration (FAA) Weather Technology in the Cockpit (WTIC) program has sponsored an operational demonstration to provide satellite-based meteorological information to commercial flights in remote and oceanic regions. This effort is called the Remote Oceanic Meteorology Information Operational (ROMIO) demonstration. For this effort, the National Center of Atmospheric Research (NCAR) developed two weather products: 1) Cloud Top Height (CTH), and 2) Convection Diagnosis Oceanic (CDO). The CTH product displays cloud top contours at flight altitudes of FL320, FL340, FL360, FL380, and FL400. The CDO product displays hazards associated with the storm updraft, lightning, and overshooting tops in four intensity levels (medium, high, severe, and extreme).In this paper, we study the potential benefits of the ROMIO demonstration through survey analysis to measure pilots’ acceptance and the ROMIO-aided behavior during en-route convective weather avoidance. We created a post-flight pilot survey to have a qualitative measure of the benefits of using the ROMIO application and to assess users' acceptance of the new airborne information technology. The questions in the questionnaire were mainly categorized into five groups: 1) decision-making, 2) workload, 3) situational awareness, 4) efficiency, and 5) quality of information. We applied Wilcoxon’s rank-sum test to analyze Likert scale responses. The study includes 105 pilot survey responses. The results of this study improve our understanding of the potential benefits of new airborne weather information technology from the pilots’ perspective and allow us to identify potential areas for further improvement of the ROMIO demonstration.
