结合现代航线驾驶工作特性及CRM和TEM模型基础上, 通过文献分析、专家访谈和开放式问卷调查, 筛选出现代航线飞行员驾驶安全所必备的27种关键行为特征, 构成中国文化背景下航线驾驶安全行为评价量表的检测项目。对118名中国航线飞行员测评数据的验证性因素分析表明, 由自动化系统认识、领导和管理、情境意识与决策、人际交流与合作技能组成的四维模型优于其他假设模型, 且在四个飞行阶段中均具有良好的信度和结构效度。以其中86名飞行员的安全绩效考核(安全规章、飞行作风、飞行技能和机组管理)数据和飞行员在每个飞行阶段的驾驶安全行为总体表现为效标变量, 以航线驾驶安全行为评价量表四个维度上的驾驶行为特征为预测变量分别进行层次回归分析, 结果表明: 航线驾驶安全行为多维评价量表具有良好的预测效度; 四个维度变量对维护不同飞行阶段的驾驶安全行为分别具有显著的贡献性, 且这种贡献性因飞行阶段的任务不同而有所差异。航线安全驾驶行为多维评价量表的构建, 不仅为航线飞行员安全驾驶行为规范性评估、机组驾驶行为问题诊断以及安全绩效考核提供了一套客观有效的评价工具, 而且也为有针对性的设计航线飞行员选拔模式和有效实施机组人员非技术性技能/CRM训练提供了一个良好的理论基础。     

航线飞行安全文化特征评价方法的因素分析研究

本研究采用航线飞行管理态度调查量表（FMAQ2．0,国际版）,旨在通过对中国航线飞行员试用结果的分析考察FMAQ2．0的因素结构及其在评价中国航线飞行安全文化特征的有效性。本量表主要由基本工作态度、飞行管理态度、自动化驾驶态度三个分量表所构成。在对来自国内四大骨干航空公司174名航线飞行员测试结果进行因素分析的基础上,分别提取出了组织信任度、工作满意度、交流协作、权力梯度、风险意识、自动化依赖和自动化认识等七个表征现代航线色行安全文化特征的主因素。研究结果初步表明,FMAQ2.0具有良好的信度和效度,符合心理测量学标准,能够作为评价和分析航线飞行安全文化特征的工具。     

飞行管理态度对航线飞行驾驶行为规范性的影响

在对航线飞行管理态度量表进行验证性因素分析的基础上,通过对飞行员航线飞行中所表现出的驾驶行为规范性水平的实时评估, 着重探讨了飞行管理态度与航线飞行员驾驶舱操作行为规范性水平之间的关系。结果表明： （1）由基本组织态度、驾驶舱工作态度和自动化驾驶态度所构成的航线飞行管理态度量表三因素结构模型具有良好的拟合效果和较高的信、效度,达到了心理计量学的标准。（2）基本组织态度中的组织信任度和工作满意度分别对驾驶舱工作态度和自动化驾驶态度产生显著影响,但并不直接影响飞行员的驾驶行为,而驾驶舱工作态度和自动化驾驶态度两个因素对航线飞行驾驶行为的规范性有显著影响。研究提示,基本组织态度通过驾驶舱工作态度和自动化驾驶态度间接影响驾驶行为的规范性。因此,驾驶舱工作态度和自动化驾驶态度构成了影响航线飞行员驾驶行为规范性的两个重要中介变量。研究为中国文化背景下的航空安全文化特征诊断和CRM训练奠定了一定的工作基础

飞行学员进近阶段易犯错误的心理因素分析

飞行进近阶段是飞行话动的重要阶段,任务数多、对飞行技能的要求高,是飞行学员出现错误较多的阶。本从心理因素和心理品质对飞行活动产生影响的角度,对飞行学员在进近阶段易犯的三种错误类型(进近时出现偏差未及时修正、对进近下降梯度的控制缺乏难确性、注意力分配忙乱导致飞机状态丢失)进行了分析,提出了飞行学员在学习和掌握进近阶段的飞行技能时,从心理因素和心理品质方面应该注意的问题。     

航线飞行员危险态度测量及对驾驶安全行为的影响

为了探讨现代航线飞行员危险态度特点及其与驾驶安全行为的关系,采用文献分析、问卷调查和专家访谈,编制了中国文化背景下航线飞行员危险态度问卷,并对中国南方航空公司257名飞行员进行调查。结果发现,自信、冲动性、男子气概、焦虑、服从性和风险意识等因素能解释飞行员危险态度总体变异的60.275%,同时对驾驶安全行为产生显著负向影响。这一结果表明六维结构模型具有较好的信度和效度,可以作为现代航线飞行员驾驶安全行为评估的预测指标。     

飞行中惊吓和惊奇的管理——拓展的Landman模型

在飞行活动中,飞行员的惊吓和惊奇反应是导致飞行失控的重要因素。惊吓和惊奇反应可能使飞行员熟练训练过的操作程序和技能被遗忘,取而代之的是不适当的直觉性的行为或草率的决策。现有的使用飞行模拟器的研究表明,Landman模型对减轻飞行员惊吓和惊奇的训练有重要价值。在Landman模型的基础上,我们加入了飞行员心理能力的个体间差别（即拓展的Landman模型）,因此拓展的Landman模型对于飞行员的选拔和训练将具有重要意义。     

航空决策模型及其影响因素分析

航空决策指在航空飞行驾驶过程中,飞行员面对特定情境做出最佳决策时的心理过程。情景评估和风险评估是航空决策模型中最重要的两个阶段。个体认知因素、疲劳和动机因素以及知识经验的限制会导致不良航空决策,组织压力和社会因素则通过混淆飞行员对飞行安全的看法间接影响航空决策。在未来的研究中,研究者应当重视构建更合理的航空决策模型,从辩证的角度全面看待知识经验与飞行安全的关系,加强对动机因素和环境因素的调查分析和实验性研究。     

飞行员风险知觉的影响因素及加工机制

风险知觉作为风险管理的核心成分,显著影响飞行安全。本文首先综述了飞行员风险知觉的影响因素,发现飞行环境、飞行员特征和组织文化等均会对飞行员的风险知觉产生影响。其次,借鉴汽车驾驶员危险知觉模型,比较飞行员与汽车驾驶员的差异性,并结合影响飞行员风险知觉的因素提出飞行员的风险知觉是一个包括风险识别、风险评价和行为倾向的三阶段加工过程,且采用串行和并行相结合的方式进行加工。最后,就飞行员风险知觉加工机制和影响因素研究的不足提出建议。     

认知特征、场独立性与飞行空间定向关系的研究

通过认知分化测验（ＣＬＢ）、团体镶嵌图形测验（ＧＥＦＴ）以及飞行定向水平的模糊评价技术,旨在检验认知特征、场独立性和飞行空间定向水平之间的关系。研究结果表明;（１）高水平的视觉空间认知能力及较强的场独立性特征不仅有助于获得一个良好的飞行定向水平,而且还构成了预测定向水平差异的有效指标;（２）场独立性特征与空间认知特征之间存在着一个很高的相关。具有较强场独立性特征的飞行员往往也具有较为典型的空间认知特征;（３）错觉水平较低的飞行员与中、重度错觉水平组飞行员在空间认知、认知分化和场独立性上的得分分别构成了显著的差异,表明轻度组飞行员在空间定向中表现出了良好的视觉空间信息组织、加工和某些元认知技能方面的优势。研究结果进一步证明了视觉空间认知加工和场独立性水平与飞行空间定向之间的紧密关系。     

National culture and flight deck automation: results of a multination survey

Attitudes regarding flight deck automation were surveyed in a sample of 5,879 airline pilots from 12 nations. The average difference in endorsement levels across 11 items for pilots flying automated aircraft in 12 nations was 53%, reflecting significant national differences in attitudes on all items, with the largest differences observed for preference and enthusiasm for automation. The range of agreement across nations was on average four times larger than the range of agreement across different airlines within the same nation, and roughly six times larger than the range across pilots of standard and pilots of automated aircraft. Patterns of response are described in terms of dimensions of national culture. Implications of the results for development of safety cultures and culturally sensitive training are discussed.     

Cockpit-cabin communication: II. Shall we tell the pilots?

In a previous article (Chute & Wiener, 1995), we explored the coordination between the "two cultures" in an airliner's crew: cockpit and cabin. In this article, we discuss a particular problem: the dilemma facing the cabin crew when they feel that they have safety-critical information and must decide whether to take it to the cockpit. We explore the reasons for the reluctance of the flight attendant to come forward with the information, such as self-doubt about the accuracy or importance of the information, fear of dismissal or rebuke by the pilots, and misunderstanding of the sterile cockpit rule. Insight into crew attitudes was based on our examination of accident and incident reports and data from questionnaires submitted by pilots and flight attendants at two airlines. The results show confusion and disagreement about what is permissible to take to the cockpit when it is sterile, as well as imbalances in authority and operational knowledge. Possible remedies are proposed.     

Effects of flight workload on urinary catecholamine responses in experienced military pilots

This study investigated the flight responses induced by strenuous aerobatic demonstration flight and an air-to-air combat maneuvering flight in experienced pilots. Subjects were 54 military male pilots on a volunteer basis: 8 T-4 pilots (M= 35.8 yr., SD=4.9), 15 F-4 pilots (M=32.6 yr., SD=5.1), 13 F-15 pilots (M=33.8 yr., SD=1.0), and 18 F-2 pilots (M=33.7 yr., SD=3.9). Samples of urine were collected approximately 30 min. before and 20 min. after the flights. The postflight adrenaline in all pilots was significantly higher than at preflight, while a significant increase in noradrenaline at postflight was not observed. The post-/preflight ratio of adrenaline in all pilots was relatively similar and high. These findings might be regarded as a result of autonomic nervous system response to the flight workload of military pilots. Especially is increment in sympathetic activity considered to play an important part in psychological adaptation to flight.     

The influence of expertise and task factors on age differences in pilot communication

The influence of expertise and task factors on age differences in a simulated pilot-Air Traffic Control (ATC) communication task was examined. Young, middle-aged, and older pilots and nonpilots listened to ATC messages that described a route through an airspace, during which they referred to a chart of this airspace. Participants read back each message and then answered a probe question about the route. It was found that pilots read back messages more accurately than nonpilots, and younger participants were more accurate than older participants. Age differences were not reduced for pilots. Pilots and younger participants also answered probes more accurately, suggesting that they were better able to interpret the ATC messages in terms of the chart in order to create a situation model of the flight. The findings suggest that expertise benefits occur for adults of all ages. High levels of flying experience among older pilots (as compared with younger pilots) helped to buffer age-related declines in cognitive resources, thus providing evidence for the mediating effects of experience on age differences.     

Autogenic Feedback Training Exercise and pilot performance: enhanced functioning under search-and-rescue flying conditions

Studies have shown that autonomous mode behavior is one cause of aircraft fatalities due to pilot error. In such cases, the pilot is in a high state of psychological and physiological arousal and tends to focus on one problem, while ignoring more critical information. This study examined the effect of training in physiological self-recognition and regulation, as a means of improving crew cockpit performance. Seventeen pilots were assigned to the treatment and control groups matched for accumulated flight hours. The treatment group contained 4 pilots from HC-130 Hercules aircraft and 4 HH-65 Dolphin helicopter pilots; the control group contained 3 pilots of HC-130s and 6 helicopter pilots. During an initial flight, physiological data were recorded on each crewmember and an instructor pilot rated individual crew performance. Eight crewmembers were then taught to regulate their own physiological response levels using Autogenic-Feedback Training Exercise (AFTE). The remaining participants received no training. During a second flight, treatment participants showed significant improvement in performance (rated by the same instructor pilot as in pretests) while controls did not improve. The results indicate that AFTE management of high states of physiological arousal may improve pilot performance during emergency flying conditions.     

THE EFFECT OF FEEDBACK ON THE ACCURACY OF CHECKLIST COMPLETION DURING INSTRUMENT FLIGHT TRAINING

This study examined whether pilots completed airplane checklists more accurately when they receive postflight graphic and verbal feedback. Participants were 8 college students who are pilots with an instrument rating. The task consisted of flying a designated flight pattern using a personal computer aviation training device (PCATD). The dependent variables were the number of checklist items completed correctly. A multiple baseline design across pairs of participants with withdrawal of treatment was employed in this study. During baseline, participants were given postflight technical feedback. During intervention, participants were given postflight graphic feedback on checklist use and praise for improvements along with technical feedback. The intervention produced near perfect checklist performance, which was maintained following a return to the baseline conditions.
