Descriptive epidemiology of 2007 homebuilt aircraft accidents and accident and fatality rates
Abstract: Homebuilt aircraft are those that the builder has completed at least 51% of the construction themselves. From 1993 National Transportation and Safety Board data, homebuilt aircraft made up only 3% of the flying hours but were involved in 10% of the general aviation accidents in the United …

The Impact of Birthdate Biorhythms on Aviation Accidents Involving Hellenic Air Force Fighter Pilots
… the impact of birthdate biorhythm on aviation accidents involving Hellenic Air Force fighter pilots. A list of names, birthdates, and the dates of accidents was compiled from accidents involving pilots who had flown fighter aircraft and have reacted improperly even though they had sufficient …

Convection from manufactured ice roughness with varying flux boundary conditions.
It is well understood that aircraft wing icing adds weight, increases drag coefficients, decreases lift coefficients, and reduces stall margin, which can lead to aircraft accidents. To predict the shape of these ice accretions, codes, such as the NASA LEWICE code, have been created that step …

UNEXPECTED TRANSITION FROM VFR TO IMC: AN EXAMINATION OF TRAINING PROTOCOLS TO MITIGATE PILOT GAPS IN KNOWLEDGE AND PERFORMANCE
During the past ten years, there have been 264 aircraft accidents identified as Visual Flight Rules (VFR) into Instrument Meteorological Conditions (IMC). These accidents have a nearly 90% fatality rate and hundreds of people have been fatally injured (ASI, 2014a). The general aviation community, …

Tailoring an Airworthiness Document to Unmanned Aircraft Systems: A Case Study of MIL-HDBK-516C
With the popularity of unmanned aircraft systems (UAS), there is a growing need to assess airworthiness for safe operations in shared airspace. In the context of this thesis, shared airspace implies the introduction of UAS into airspace designated for manned aircraft. Airworthiness guidelines are …

Effects of Online Training on Aircrew Monitoring Behaviors: A Field Study
<p>Data from aircraft accidents and line observation studies indicate that inadequate pilot monitoring is a growing safety concern. In the cockpit environment, pilots who fail to properly manage their workload commit more monitoring errors. Given the lack of training and educational programs …

A review of hijack events by airline employees, with a particular reference to Pilot Suicide Using an Aircraft (PSUA): an analysis of the triggering factors and current mitigation
… public attention on Pilot Suicide Using Aircraft accidents or (PSUA), the term used throughout this thesis. The Lubitz event led to the introduction of procedures that called for an in-flight minimum of two crew members in the cockpit and pilots psychometric testing. However, the new …

Galvanic Vestibular Stimulation Applied to Flight Training
… spatial disorientation resulted in at least 202 aircraft accidents, 184 of them resulting in fatalities. Galvanic Vestibular Stimulation (GVS) provides a cost effective and safe way to simulate spatial disorientation and potentially test pilot’s vestibular system prior to aircraft operation. This …

Divergence between the human state assumption and the actual aircraft system state
… involving human-system interaction. Many recent aircraft accidents involve divergence between the crew state assumption and the actual system state. As aircraft systems and automation become more complex, it's possible that the consequential effects of divergence, illustrated by these accidents, …

The causes and consequences of divergence between the air traffic controller state awareness and actual system state
… systems and future systems where unmanned aircraft will be integrated. Prior studies identified pilot divergence as a factor in several recent aircraft accidents and could be a factor for controllers. The future addition of unmanned aircraft in national airspace is a significant change …

The Effects of Angle-of-Attack Indication on Aircraft Control in the Event of an Airspeed Indicator Malfunction
… that loss of control is the leading cause of aircraft accidents. Further evaluation of the data indicates that the majority of loss of control accidents are caused by the aircraft stalling. In response to these data, the Federal Aviation Administration and the General Aviation Joint Steering …

Flight deck engineering: impact of flight deck crew alerting and information systems on English as a second language flight crewmembers performance in airline flight operations
… technical documentation. Contributory causes of aircraft accidents have been due to misunderstandings of crew alerts and procedural divergence by English as-a-second language flight crewmembers (ESL). Research was conducted to understand impact of written English language technical information on …

The evaluation of the 90 second certification test and the analysis of human behaviour within aircraft evacuation modelling
The majority of fatalities during an aircraft accident occur after impact with approximately 95% due to burns and smoke inhalation due to sub optimal evacuations. If post-crash survivors can be evacuated quickly enough then the survival rate could be improved. This thesis will examine the influence …
