Beyond The Checklist: Pilot Education, Aviation Resources, And Health Management Skills, Nancy Smith

Pacific Journal of Health

The research study investigates if pilots find aviation health-related materials provided from training or aviation associations to support their own health needs. A mixed methods convergent parallel design was conducted by sampling 27 pilots within general aviation to assess their utilization of aviation health-related materials, health management skills including self-efficacy and prioritization, as well as their views of implementing particular health topics into aviation training. Results of the study indicate that it is unclear if pilots find aviation health materials useful in managing their health, pilots have a relatively high level of self-efficacy and ability to prioritize one’s health and …

Assessing The Influences Of Electronic Flight Bags On General Aviation Single Pilots’ Situation Awareness In Various Conditions, Dongguang Yu

Doctoral Dissertations and Master's Theses

The widespread adoption of Electronic Flight Bags (EFBs) among general aviation pilots prompts safety concerns regarding transitioning from traditional, heavily loaded paper-based flight bags. However, studies evaluating the impact of EFBs on general aviation pilots’ situation awareness are limited. This study aimed to determine whether EFBs enhanced or hindered general aviation pilots’ situation awareness.

The research compared EFBs with traditional paper-based flight bags to investigate pilots’ situation awareness in a single-pilot flight deck under visual flight rules, normal and emergency flight scenarios, and different mounting positions. A sample of 38 participants was recruited, including flight students, flight instructors, and retired …

Assessing Safety Culture: Lessons From The Aviation Industry, Mirrette Gendi, Cheri L. Marcham, Michael O'Toole

Publications

SAFETY CULTURE has been a topic of debate in academia as much as it has been in the practice of various industries (Zohar, 2010). Although the concept and definition of safety culture and what it entails have consumed much of the debate, the assessment of safety culture has been the most controversial. Yet, on the academic level, the topic of monitoring and measuring safety culture has seen limited research that offers reliable and valid assessment tools (Goodheart & Smith, 2014), especially when compared to the importance of safety culture as a component of a safety management system (SMS).

Is Declined Cognitive Function Predictive For Fatal Accidents Involving Aging Pilots?, Douglas D. Boyd, Alan J. Stolzer

Publications

Civil aviation comprises airlines/charters and general aviation (GA). Currently, airlines are experiencing a pilot shortage, partly reflecting scheduled retirements mandatory for airline (but not GA) pilots aged 65 years, fueling a debate as to whether the retirement age should be increased. Herein, using 16–40 years-of-age aviators as a reference, we determined whether GA pilots aged 60+ years (i) incurred an elevated accident rate, employing, for the first time, age-tiered flight time as a measure of risk exposure and (ii) carried an excess risk for cognitive deficiency-related fatal accidents. Methods. Airplane accidents (2002–2016) involving Class 3 medical certificated pilots were per …

Journal of Aviation Technology and Engineering

This article provides a perspective on how an internet of heterogeneous self-service airport terminal systems can be used for data collection, which is stored on a private or consortium blockchain depending on the ownership or operations of an airport or both. Such a setup would help to increase efficiency, reduce costs, and improve traveler experience at airport terminals. Moreover, it would allow airports to gather data directly from passengers as opposed to waiting to receive the same data from airlines. Subsequently, this data, now on a blockchain system, becomes a data source for other applications such as machine learning. In …

Energy Safety Management: A Training Model To Improve Flight Safety, Juan R. Merkt, Matthijs H. J. Amelink, David G. Sizoo

Journal of Aviation Technology and Engineering

Failing to properly manage an airplane’s energy state can be unforgiving. Mismanagement of mechanical energy (altitude and/or airspeed) is a contributing factor to three common types of fatal accidents in aviation: loss of control in flight, approach and landing accidents, and controlled flight into terrain. Recognizing the importance of energy management, the Federal Aviation Administration has incorporated new elements into the Airman Certification Standards, emphasizing knowledge of energy management concepts and the consequences of mishandling an airplane’s energy state. Unfortunately, no adequate guidance has been available in terms of defining key energy management concepts or suggesting how these should be …

Aviation Faculty Publications

In this study, the duality of adaptive capacity in aviation safety is examined, where the need for resilience of frontline workers conflicts with the expectations and assumptions of upstream entities, leading to system brittleness. We explore three critical categories: responsibilization, the application of practical wisdom in navigating challenging situations, and the unrecognized sacrifices that accompany adaptation. A qualitative research design is used, using three focus groups consisting of pilots in a European airline, the airline’s safety department, and the respective civil aviation authority. The study's findings reveal i. significant organizational constraint and pressure on pilots, resulting in workarounds, personal playbooks, …

Exploring A New Conceptual Framework In Aviation Maintenance Incident Reporting Using Natural Language Processing, Christopher P. Braun

Doctoral Dissertations and Master's Theses

In the analysis of human error incidents, human factors specialists predominantly follow two schools of thought in categorization strategies. One is to categorize the operator’s actions by the physical properties of the activity (phenotypes); the other focuses on the cognitive behaviors preceding the incident (genotypes). These categorization strategies are intended to foster an understanding of the events, identify risks, and assist in the implementation of risk reduction interventions. Commercial aviation maintenance presents unique challenges to human factor practitioners in terms of task requirements, working environments, communication modalities, and safety standards. Complex tasks are handed from one shift of personnel to …

Situation Awareness Assessment Of Enhanced Stable Approach Flight Instrument Displays, David J. Hunter

Doctoral Dissertations and Master's Theses

Through the year 2022, runway-related events, including excursions, abnormal runway contact, and runway undershoot and overshoot, were the third leading causes of fatal aircraft accidents. Principal to these runway-related accidents was the presence of an unstable approach. Pilots currently must depend on the timely recall of stable approach criteria stored in long-term memory, application of those criteria against current flight conditions, perception and cognition of deviation from those criteria, and determination of potential courses of action. Such recall is fallible, and challenges to perception and cognition are ever-present.

This study examined whether the presentation of stable approach criteria boundaries and …

Two Heads Are Better Than One: Single Pilot Operation Threatens The Safety Of The Friendly Skies, Alexandria E. Rook

Arkansas Law Review

Boeing’s Maneuvering Characteristics Augmentation System (“MCAS”), an automated piloting system, is only supposed to handle aircraft operations in very specific circumstances. Despite devasting results with MCAS, Boeing has another automated piloting system on the horizon that poses even more grave risks: Single Pilot Operation (“SPO”). Boeing—along with Airbus—wants to replace one of the pilots in the cockpit of commercial airline flights with the new SPO technology it is developing. The FAA should not allow SPO technology to be implemented because it is premature, motivated by financial gain to the detriment of safety, and ignores the importance of professional judgment in …

A Review And Analysis Of General Aviation Instructional Accidents, Sydney Sommers

Mechanical Engineering Undergraduate Honors Theses

General aviation student pilot accidents represent a substantial portion of all aviation accidents in the United States. Almost 50% of general aviation accidents involve student pilots. Analyzing historical accident reports is the most common approach to studying accident causation. The National Transportation Safety Board (NTSB) investigates all civil aviation accidents in the US. Using the NTSB data, I analyzed general aviation student pilot accidents in the US between 2013 and 2022. Results indicate that most accidents take place in California and Florida and can be attributed to student pilots between 18 and 65 years of age. Alaska and Maine had …

An Investigation Into In-Flight Loss Of Control Accidents Due To Horizontal Stabilizer Changes On The Piper Cherokee, Connor John Geran

Theses and Dissertations

Loss of Control (LOC) while in-flight in General Aviation (GA) has been the subject of intense research by academic institutions and regulatory agencies in recent years [4] [9] [11] [19] [20] [21]. This interest is primarily due to a disproportionate number of all aircraft accidents occurring within the GA category of flight, with 94% of accidents in 2022 occurring within GA, caused primarily by pilot LOC, with 42% of accidents having LOC as the listed cause. Research into this subject at FIT yielded the results that many common GA aircraft tend to experience a strong pitch up response after undergoing …

Survival After Ditching In Motorized Aircraft, 1989-2022, Douglas D. Boyd, Volker C. Schick, Catherina Hippler, Jochen Hinkelbein

Publications

INTRODUCTION: Although an unintended aircraft landing on water (referred to as ditching) is a rare event, the potential for occupant injury/fatality increases immediately following the event due to adverse conditions. However, to date, few studies have addressed the subject. Herein, ditching events and post-ditching survival were investigated.

METHODS: Ditchings (1982–2022) in the United States were identified from the National Transportation Safety Board database. Occupant injury severity, aircraft type, pilot experience, flight conditions, and number of occupants were extracted. Poisson distribution, the Chi-squared test (2-tailed), Mann-Whitney U test, and Kruskal-Wallis one-way analysis of variance were employed.

RESULTS: A total of 96 …

Assessing Past Airworthiness Directives And How Safety Management Systems May Benefit Aviation Product Design And Manufacturing, Damon Lercel, Manoj Patankar, Richard Steckel

Journal of Aviation/Aerospace Education & Research

The European Union Aviation Safety Agency (EASA) continues to promulgate Safety Management Systems (SMS) across aviation organizations when it recently issued SMS requirements for EASA certificated Part 145 maintenance, repair and overhaul (MRO) organizations and Part 21 Design & Manufacturing (D&M) organizations. Currently, the Federal Aviation Administration (FAA) has no such rule in place for these U.S.-based organizations, which may challenge those doing business in countries where EASA policies apply. Given that a majority of the United States’ D&M and MRO population is made up of smaller organizations, it is likely a U.S. SMS regulation will require justification of the …
