The Federal Aviation Administration’s 2014 annual airman certificate demographics report revealed that women comprise roughly 23% of the non-pilot certificated airman in the United States; however, only 2.3% of the certified aircraft mechanic workforce are women. The problem explored in this mixed-methods concurrent triangulation study was the literature gap regarding factors that impact the demographic disparity between men and women in the aircraft maintenance technician field. The purpose of the study was to understand why most women choose not to become aircraft mechanics. A total of 431 female participants completed a 13-question survey containing 5-point Likert and open-ended questions to collect quantitative and qualitative data that addressed the research question. Results indicated that neither motherhood nor marriage were factors that impacted a woman’s interest in a career as an aircraft maintenance technician. Furthermore, there was a relationship between a woman’s perception of physical limitations as a mechanic, career appropriateness, work environment safety, social acceptance, and advancement opportunities. Finally, the qualitative analysis yielded a substantial amount of informative themes and nodes that illuminated a general lack of women’s knowledge regarding the field and a perception of sexual discrimination if one were to start such a career.
美国联邦航空管理局(Federal Aviation Administration) 2014年年度飞行员证书人口统计报告显示,女性约占美国非飞行员认证飞行员的23%;然而,只有2.3%的持证飞机机械师是女性。在这项混合方法并行三角测量研究中,探讨的问题是关于影响飞机维修技术人员领域男女人口差异因素的文献缺口。这项研究的目的是了解为什么大多数女性不选择成为飞机机械师。共有431名女性参与者完成了一项包含五点李克特和开放式问题的13个问题的调查,以收集解决研究问题的定量和定性数据。结果表明,母性和婚姻都不是影响女性对飞机维修技师职业兴趣的因素。此外,女性对技工身体缺陷的认知与职业适宜性、工作环境安全、社会接受度和晋升机会之间存在关系。最后,定性分析产生了大量的资料主题和节点,说明妇女对这一领域普遍缺乏知识,如果开始从事这一职业,就会感到性别歧视。

Ground-based laser illuminations directed towards arriving and departing aircraft have increased in the past decade. A laser aimed at the windshield of an aircraft may distract a pilot and compromise safety. Previous studies provided empirical evidence of laser intensity in the flight deck from ground-based laser illumination events and the potential for adverse effects to flight safety. Most recent studies focused on testing the application of various coatings to aircraft windshields in order to reduce the effects of laser exposure to crewmembers. Safe and efficient flight operations depend on the ability of a pilot to see normal spectrums of color. Therefore, this study used the Ishihara Pseudoisochromatic Plates Color Vision Test to investigate participants’ color perception through an aircraft windshield coated with a photoresponsive nanocomposite film designed to reduce laser intensity from entering a flight deck. This study tested the hypothesis that there were no differences between color vision test scores when conducting trials with coated and non-coated windshields. Participants were individuals who held a current FAA medical certificate and held a minimum of a student pilot certificate (N = 104). Data analysis consisted of a repeated measures design that included within-subjects factors where each of the participants was tested from two trials, each under two conditions: coated and non-coated. The order of trials was altered using a counterbalancing technique which also provided a between-subjects factor. A paired-samples t-test was calculated to compare the mean of error by participants when taking the Ishihara Test through the non-coated windshield to the mean of the error by participants when taking the test through the coated windshield. No significant difference from the non-coated to the coated windshield was found (t(103) = 1.274, p > 0.05, n = 104). Findings suggest that effective color vision can be maintained through photoresponsive nanocomposite coatings.
在过去十年中,针对抵港和离港飞机的地面激光照明有所增加。瞄准飞机挡风玻璃的激光可能会分散飞行员的注意力,危及安全。先前的研究提供了地面激光照射事件中飞行甲板激光强度的经验证据,以及对飞行安全的潜在不利影响。最近的研究集中在测试各种涂层在飞机挡风玻璃上的应用,以减少激光照射对机组人员的影响。安全有效的飞行操作取决于飞行员看到正常光谱的能力。因此,本研究使用石原伪等色板色觉测试来研究参与者通过涂有光响应纳米复合薄膜的飞机挡风玻璃的色觉,该薄膜旨在降低进入飞行甲板的激光强度。这项研究验证了这样一种假设,即在使用涂层和非涂层挡风玻璃进行试验时,色觉测试分数之间没有差异。参与者是持有美国联邦航空管理局现行医疗证书并至少持有学生飞行员证书的个人(N=104)。数据分析包括重复测量设计,其中包括受试者内部的因素,其中每个参与者都在两种条件下接受了两次试验的测试:涂层和非涂层。使用平衡技术改变了试验顺序,该技术还提供了受试者之间的因素。计算成对样本t检验,以比较参与者在通过无涂层挡风玻璃进行石原测试时的误差平均值与参与者在通过涂层挡风玻璃测试时的错误平均值。无涂层挡风玻璃与有涂层挡风玻璃之间无显著差异(t(103)=1.274,p>0.05,n=104)。研究结果表明,通过光响应纳米复合涂层可以保持有效的色觉。

An Analysis of Cabin Ozone Regulations 客舱臭氧法规分析
Q3 Social Sciences Pub Date : 2018-09-01 DOI: 10.22488/OKSTATE.18.101002
Taylor Pottinger, Cheryl L. Marcham
Exposure to elevated levels of ozone have been reported to be associated with complaints of discomfort such as dry mouth, eye irritation and dryness, nasal irritation coughing, and headaches.  The Federal Aviation Administration (FAA) established regulatory requirements in 1980 to limit cabin ozone levels to no more than 0.25 parts per million (ppm) at any time or 0.1 ppm averaged over a 3-hour interval for any flight over four hours in length.  The FAA also published an Advisory Circular (AC), AC 120-38, to provide guidance to air carriers on how to comply with these then new ozone regulations. Methods of compliance include the use of catalytic converters, or ozone filters, designed to remove ozone, utilizing statistical methods to prove that ozone concentrations will not exceed limits for the carrier’s route structure and flight planning to avoid areas of reported high concentrations of ozone. The calculations used to determine cabin ozone concentration from manufacturer’s filter efficiency data and ozone levels are to be based on published ozonesonde data found in the AC 120-38 or an equivalent data set.  Unfortunately, the published ozonesonde data in the AC 120-38 are outdated and the AC does not point to any other data source that is acceptable to the FAA to conduct the required statistical analysis. In addition, once compliance is shown, no follow-up measurements are required to ensure that ozone levels remain below these required levels.  Actual ozone concentrations have been measured in the aircraft by several researchers that exceed these regulatory levels. Finally, FAA ozone regulations and AC 120-38 do not address cumulative effects of ozone exposure to crewmembers over multiple flights and do not offer any protection against ozone exposure for crewmembers on non-passenger carrying flights. A revision of federal regulations to afford protection to all crewmembers, account for cumulative effects, and updated compliance methods that rely on current ozonesonde data and periodic ozone monitoring should be accomplished to ensure crewmembers are not subjected to ozone levels that could potentially result in serious health concerns.
据报道,暴露在臭氧水平升高的环境中会引起口腔干燥、眼睛刺激和干燥、鼻腔刺激、咳嗽和头痛等不适症状。美国联邦航空管理局(FAA)于1980年制定了监管要求,将客舱臭氧水平限制在任何时候都不超过百万分之0.25,或将超过四小时的任何飞行在3小时内的平均臭氧水平限制为百万分之0.1。美国联邦航空局还发布了一份咨询通告(AC),AC 120-38,为航空公司提供如何遵守这些当时新的臭氧法规的指导。遵约方法包括使用旨在去除臭氧的催化转化器或臭氧过滤器,利用统计方法证明臭氧浓度不会超过承运人航线结构和飞行计划的限制,以避免报告的臭氧高浓度区域。用于根据制造商的过滤器效率数据和臭氧水平确定客舱臭氧浓度的计算应基于AC 120-38中公布的臭氧探测器数据或等效数据集。不幸的是,AC 120-38中公布的臭氧探测器数据已经过时,并且AC没有指向FAA可以接受的任何其他数据源来进行所需的统计分析。此外,一旦证明符合要求,就不需要进行后续测量,以确保臭氧水平保持在这些要求水平以下。几位研究人员已经测量到飞机上的实际臭氧浓度超过了这些监管水平。最后,美国联邦航空局臭氧条例和AC 120-38没有解决多次飞行中臭氧暴露对机组人员的累积影响,也没有为非载客航班上的机组人员提供任何防止臭氧暴露的保护。应修订联邦法规,为所有机组人员提供保护,考虑累积影响,并根据当前臭氧探测器数据和定期臭氧监测更新合规方法,以确保机组人员不会受到可能导致严重健康问题的臭氧水平的影响。

The phenomenon of encountering instrument meteorological conditions (IMC) on a visual flight rules (VFR) flight has been the focus of several previous studies. Most of these past studies, though, have involved examining various databases quantitatively or via a mixed-methods approach in search of possible causal factors such as pilot characteristics, weather conditions, aircraft type, and time of day. Missing from the literature are qualitative studies that tell the story of pilots who actually experienced such flights. To help fill this gap in the aviation literature, the purpose of the current study was to describe the first-hand experiences of GA pilots who inadvertently flew VFR-into-IMC. Participants consisted of 11 male pilots who previously had flown from VFR-into-IMC inadvertently at some point during their aviation career. The study used a phenomenological approach to describe participants’ shared experiences and then applied grounded theory to develop a set of conjectures derived inductively from participants’ responses. Using Spradley’s (1979) domain analysis to categorize common themes and patterns, the major domains of Weather Considerations and Expectations, Thoughts and Actions, and Postflight Experiences emerged. Major findings from the first domain revealed that as part of their preflight actions prior to departure, participants received a weather briefing, gave little consideration to overall weather conditions, neither expected nor anticipated IMC, and used a variety of communication resources to keep current with weather related issues. Major findings from the second domain revealed that participants recognized changes in the weather en route, used various communication resources to assess their current condition, reacted to IMC by trying to avoid and escape it, expressed feelings of trepidation about what they should do, were surprised over how the weather was not what they expected, and reverted to their training to get out of IMC. Major findings from the third domain revealed that participants’ postflight actions ranged from doing nothing to submitting a report to NASA’s ASRS, and that lessons learned included acquiring a heightened sense of situational awareness, a need to do a better job in alternative planning, and a greater appreciation for the weather. A comparison of these findings to past studies and theory are discussed, and implications and recommendations for practice and research are provided.
目视飞行规则(VFR)飞行中遇到仪表气象条件(IMC)现象一直是前人研究的重点。然而,过去的大多数研究都涉及到定量地检查各种数据库,或者通过混合方法来寻找可能的因果因素,如飞行员特征、天气条件、飞机类型和一天中的时间。文献中缺少的是讲述实际经历过这种飞行的飞行员故事的定性研究。为了帮助填补航空文献中的这一空白,本研究的目的是描述无意中将vfr飞行到imc的GA飞行员的第一手经验。参与者包括11名男性飞行员,他们之前在他们的航空生涯中无意中从vfr飞到imc。本研究采用现象学方法描述参与者的共同经历,然后运用扎根理论从参与者的反应中归纳出一系列猜想。使用Spradley(1979)的领域分析对共同主题和模式进行分类,出现了天气考虑和期望、思想和行动以及飞行后体验的主要领域。第一个领域的主要发现表明,作为起飞前飞行前行动的一部分,参与者收到了天气简报,很少考虑整体天气状况,既没有预期也没有预期IMC,并使用各种通信资源来保持与天气相关的最新问题。第二个领域的主要研究结果显示,参与者认识到途中天气的变化,使用各种通信资源来评估他们目前的状况,对IMC的反应是试图避免和逃避它,表达他们应该做什么的恐惧情绪,对天气与他们预期的不一样感到惊讶,并回到他们的训练中去摆脱IMC。第三个领域的主要研究结果显示,参与者的飞行后行动范围从什么都不做到向NASA的ASRS提交报告,从中吸取的教训包括获得更高的态势感知感,需要更好地做好备选计划,以及对天气有更大的了解。本文将这些发现与以往的研究和理论进行比较,并对实践和研究提供启示和建议。

Sociability relates to one’s preference to interact with others or remain alone. The current study sought to determine how a pilot’s perceived sociability would relate to consumers’ trust ratings in their pilot using participants from India and the United States. Consumers were presented with one of two scenarios. In the control condition, the pilot was described as sociable, while in the other, the pilot was presented as unsociable. Participants were then asked to rate their trust in the pilot based off of these cues. In general, participants indicated that the pilot who was perceived as unsociable was less trusting compared to the pilot that was perceived as sociable. Americans tended to be more extreme in their trust ratings of the pilots than those participants from India. Finally, affect measures were also collected, and it was found that affect completely mediated the relationship between the sociable/unsociable conditions and trust ratings.
社交性与一个人喜欢与他人互动或独处有关。目前的研究试图确定飞行员感知到的社交能力与消费者对其飞行员的信任评级之间的关系,研究对象来自印度和美国。向消费者展示了两种场景之一。在控制条件下,飞行员被描述为善于交际,而在另一种情况下,飞行员被描述为不善交际。然后,参与者被要求根据这些线索评估他们对飞行员的信任程度。总的来说,参与者表示,与被认为善于交际的飞行员相比,被认为不善交际的飞行员更不值得信任。美国人对飞行员的信任程度往往比印度人更极端。最后,还收集了情感测量,发现情感完全中介了社交/非社交条件与信任评分之间的关系。

Understanding patterns of entry and exit decisions and determinants shaping the patterns are necessary for airline planners in drawing a robust route map and gaining their own competitive advantages.  The study used logit models to exam the relationship between two separate binary dependent variables: entry versus no-entry, exit versus no-exit, and multiple independent variables.  Dataset was extracted from the Bureau of Transportation Statistics DB1B for Quarter 1 of 2018, then was reconstructed based on original and destination (O&D) airport pairs to gain insights.  The entry decision pattern model yielded seven significant factors: total passengers, average market fare, number of carriers, distance, low-cost carriers (LCC) existence, origin hub, and destination hub.  In the meantime, the exit decision pattern model yielded all the seven aforementioned factors and two other significant factors: route type and the business model of the largest share airline.  The findings made a practical implication to airline network planners in considering determinants affecting entry and exit decisions to build a more efficient and profitable network.
了解进入和退出的决策模式和决定因素形成的模式是必要的航空公司规划者在绘制一个强大的路线图和获得自己的竞争优势。该研究使用logit模型来检验两个独立的二元因变量之间的关系:进入与不进入,退出与不退出,以及多个自变量。数据集提取自美国交通统计局(Bureau of Transportation Statistics) 2018年第一季度的DB1B数据集,然后基于原始和目的地(O&D)机场对进行重建,以获得见解。进入决策模式模型得到7个显著因素:总客运量、平均市场票价、航空公司数量、距离、低成本航空公司(LCC)存在程度、出发地枢纽和目的地枢纽。同时,退出决策模式模型得到了上述7个因素和另外两个显著因素:航线类型和最大份额航空公司的商业模式。研究结果对航空网络规划者在考虑影响进入和退出决策的决定因素以建立更高效和盈利的网络时具有实际意义。

In response to the 2009 Colgan 3407 airline crash and ensuing public concern, Public Law 111-216: The Airline Safety and Federal Aviation Administration Extension Act of 2010 was signed into law on August 1, 2010. This legislation mandated significant changes to the aviation and airline industries. Among these changes, an increase in pilot qualification standards was enforced for pilots seeking employment with US air carriers. This study explores the perceptions of aviation faculty members and flight center personnel at four-year collegiate flight training programs in the US regarding the effect of PL 111-216. Results of this national study indicate the majority of respondents believe PL 111-216 will have an adverse effect on collegiate aviation flight students, collegiate aviation flight training programs and the US air carrier industry. This study also revealed the perception that collegiate flight students will begin to pursue flight careers (non-US airline or corporate aviation) that are not directly impacted by PL 111-216.
为了回应2009年科尔根3407航空公司坠机事件以及随之而来的公众关注,2010年8月1日,《公法111-216:航空安全和联邦航空管理局扩展法案》签署成为法律。这项立法要求对航空和航空业进行重大改革。在这些变化中,对寻求在美国航空公司工作的飞行员,提高了飞行员资格标准。本研究探讨了美国四年制大学飞行训练项目中航空教员和飞行中心人员对PL 111-216的影响的看法。这项全国性研究的结果表明,大多数受访者认为PL 111-216将对大学航空飞行学生、大学航空飞行培训计划和美国航空运输业产生不利影响。这项研究还揭示了这样一种看法,即大学飞行专业的学生将开始从事飞行职业(非美国航空公司或公司航空),而这些职业不受PL 111-216的直接影响。

Controlled Rest in Position (CRIP): Consumer Perceptions in the United States 位置控制休息(CRIP):美国消费者的认知
Q3 Social Sciences Pub Date : 2015-09-01 DOI: 10.22488/OKSTATE.18.100461

Controlled rest in position (CRIP) has been suggested as a viable countermeasure to the Federal Aviation Administration (FAA) in the ongoing efforts to combat in-flight pilot fatigue. It is already in use in other parts of the world; however, it is not currently permitted in the United States. While expert opinion suggested it poses little threat to flight safety, with valuable returns in terms of improved crew alertness and performance, there is some doubt about the level of consumer buy-in. This study completed a preliminary investigation into overall consumer willingness to fly, in the use of CRIP procedures in the United States. Two studies were completed to examine consumer perceptions toward the use of CRIP. It was found in both studies that male and female participants were less willing to fly when CRIP was used. Additionally, female participants were less willing than their male counterparts in both the control and experimental condition. In the second study, affect measures were collected and found to completely mediate the relationship between the use of CRIP and consumers’ willingness to fly. Findings may provide both regulators and airlines data that could aid in their decision-making processes as it relates to implementing such practices in the United States.
在美国联邦航空管理局(FAA)持续努力对抗飞行中飞行员疲劳的过程中,可控位置休息(CRIP)已被建议作为一种可行的对策。它已经在世界其他地区使用;然而,目前这在美国是不允许的。虽然专家意见认为,它对飞行安全构成的威胁很小,在提高机组人员的警觉性和表现方面带来了宝贵的回报,但人们对消费者的接受程度存在一些疑问。本研究完成了对美国使用CRIP程序的总体消费者飞行意愿的初步调查。完成了两项研究,以检查消费者对使用CRIP的看法。两项研究都发现,当使用CRIP时,男性和女性参与者都不太愿意坐飞机。此外,在对照组和实验条件下,女性参与者比男性参与者更不愿意。在第二项研究中,我们收集了影响测量,发现它完全中介了CRIP的使用与消费者的飞行意愿之间的关系。调查结果可能为监管机构和航空公司提供数据,有助于他们在美国实施此类做法的决策过程。

Examining the Relationship between Familiarity and Reliability of Automation in the Cockpit 座舱自动化熟悉度与可靠性关系的研究
Q3 Social Sciences Pub Date : 2014-01-01 DOI: 10.22488/OKSTATE.18.100452

This study sought to determine the correlation between familiarity and perceptions of reliability, as associated to specific aviation-related automated devices. Participants’ experience levels ranged from non-pilots to novice pilots to certified flight instructors. It was hypothesized that familiarity has a direct correlation with ratings of reliability for various aviation-related automated devices and that the correlation across devices for each participant would be positive. The researchers expected to find a difference in the familiarity-reliability relationship as a function of experience. Findings showed that there was a significant positive correlation between familiarity and reliability for every single automated device. A positive correlation across automated devices for 87% of the participants was also found. Interestingly, the study did not find any relationship between experience and the  familiarity-reliability relationship.
本研究旨在确定熟悉度与可靠性感知之间的相关性,如与特定航空相关的自动化设备相关。参与者的经验水平从非飞行员到新手飞行员再到认证飞行教官。假设熟悉度与各种航空相关自动化设备的可靠性评级直接相关,并且每个参与者的设备之间的相关性将是正的。研究人员希望发现熟悉度-可靠性关系的差异,作为经验的函数。研究结果表明,每一个自动化设备的熟悉度和可靠性之间存在显著的正相关关系。87%的参与者还发现自动化设备之间存在正相关关系。有趣的是,这项研究并没有发现经验和熟悉度-可靠性之间有任何关系。

An Investigation of the Effects of Carrier Groups on Airline Quality Rating Components Using a Two-way Analysis of Variance 利用双向方差分析研究航空公司航空质量评级成分对航空公司航空集团的影响
Q3 Social Sciences Pub Date : 2013-10-01 DOI: 10.22488/OKSTATE.18.100514
John H. Mott, Branden K. Avery
The Airline Quality Rating is a quantitative determination of the quality of U.S. domestic air carriers based on parameters published by the U.S. Department of Transportation. The rating is unique in that it is of interval scale and is comparable across carriers and time periods (Bowen & Headley, 2012). In order to gain insight into the relationship of the AQR metric to the carriers to which it is applied, it is helpful to group the carriers and examine the effects of those groupings on the four individual factors that comprise the AQR. Such a methodology allows one to better understand the relationship of the AQR metric to each of the carrier groups and ultimately improve the predictability of the metric. The authors employ a two-way analysis of variance to determine differences between carrier group means for each of the four AQR factors while examining longitudinal effects, along with post-hoc difference testing. While the post-hoc test results indicate significant differences between some groupings, suggesting that separate econometric models for those groupings might be created with the goal of more accurately forecasting the metric, some of the assumptions upon which the ANOVA is predicated are violated. This article will examine those violations and suggest that further research using nontraditional methods (e.g., Bayesian analysis) is indicated.
航空公司质量评级是基于美国交通部公布的参数对美国国内航空公司质量的定量确定。该评级的独特之处在于它是间隔尺度的,并且在运营商和时间段之间具有可比性(Bowen & Headley, 2012)。为了深入了解AQR指标与所应用的携带者之间的关系,对携带者进行分组并检查这些分组对构成AQR的四个单独因素的影响是有帮助的。这样的方法使人们能够更好地理解AQR度量与每个载波组的关系,并最终提高度量的可预测性。作者采用双向方差分析来确定四个AQR因素中每个携带者组均值之间的差异,同时检查纵向影响,以及事后差异测试。虽然事后检验结果表明一些分组之间存在显著差异,这表明可以为这些分组创建单独的计量经济模型,以更准确地预测指标,但ANOVA预测的一些假设是违反的。本文将检查这些违规行为,并建议使用非传统方法(例如贝叶斯分析)进行进一步研究。
