A Qualitative Descriptive Study On Re-Assessing The Mental Certification By Faa For Future Pilots, Kaung Z. Min Sep 2022

A Qualitative Descriptive Study On Re-Assessing The Mental Certification By Faa For Future Pilots, Kaung Z. Min

Student Works

Mental illness becomes one of the main problems that most pilots do not usually address. It is not because pilots do not have the courage or are open enough to talk with someone, but because the Federal Aviation Administration (FAA) forces them to hide from mental depression. Most of the time, the pilots are not willing to declare such illnesses as they fear losing their job; simultaneously, the Federal Aviation Agencies across the world require pilots to be in peat health, including their mental condition, to operate the aircraft. While it can be said that the passengers’ and crews’ safety …

Physiological Effects During Aerobatic Flights On Science Astronaut Candidates, Pedro Llanos, Diego M. Garcia Jan 2020

Physiological Effects During Aerobatic Flights On Science Astronaut Candidates, Pedro Llanos, Diego M. Garcia

Publications

Spaceflight is considered the last frontier in terms of science, technology, and engineering. But it is also the next frontier in terms of human physiology and performance. After more than 200,000 years humans have evolved under earth’s gravity and atmospheric conditions, spaceflight poses environmental stresses for which human physiology is not adapted. Hypoxia, accelerations, and radiation are among such stressors, our research involves suborbital flights aiming to develop effective countermeasures in order to assure sustainable human space presence. The physiologic baseline of spaceflight participants is subject to great variability driven by age, gender, fitness, and metabolic reserve. The objective of …

Reimagining Icarus: Ethics, Law And Policy Considerations For Commercial Human Spaceflight, Sara M. Langston May 2018

Reimagining Icarus: Ethics, Law And Policy Considerations For Commercial Human Spaceflight, Sara M. Langston

Publications

Commercial human spaceflight presents an area for engaging novel human activity and objectives, to include space exploration, entertainment, transportation and extraterrestrial resource acquisition. The inherent dangers and lack of scientific and medical certainty involved however raise interrelated questions of ethics, bioethics, law and public policy. This is particularly the case with spaceflight participant (SFP) screening, selection, and commercial human spaceflight activities where regulations are currently silent or lacking. In the absence of established law, ethics can play an important role by informing industry standards, policies and best practices. Understanding the fundamental ethical values at stake in the application of new …


General Aviation Hypoxia And Reporting Statistics, Timothy B. Holt, Jacqueline Luedtke, Claire Schindler Apr 2017

General Aviation Hypoxia And Reporting Statistics, Timothy B. Holt, Jacqueline Luedtke, Claire Schindler

Publications

“All too often, pilots tell me they don't need physiological training because they don't fly that high. The statement points out the general feelings of a large majority of the aviation population. I suppose then the burning question is ‘why do we still have aircraft accidents?’” (Boshers, 2015). To this day there are no statistics on how often general aviation pilots experience hypoxia during everyday operations. General aviation pilots (i.e. non-commercial operations) were chosen for this study because:

  • Little regulation regarding flight physiology training
  • General attitude of invulnerability towards hypoxia
  • No requirement to report hypoxia or similar events

Crew Resource Management And Its Possible Role In Nursing Risk Management, I. R. Mcandrew, G. P. Wise Jun 2014

Crew Resource Management And Its Possible Role In Nursing Risk Management, I. R. Mcandrew, G. P. Wise

Publications

Crew Resource Management (CRM) was introduced within the aviation industry in the late 1970s after an aircraft ran out of fuel whilst the pilots were trying to solve an undercarriage problem. To reduce such errors and ultimately lower the probability of failure and the severity of risks that occur, training in CRM was rolled out across the whole industry. It has been successful over the last few years in major reductions in the number of crashes and fatalities in the commercial aviation sector. Nursing has similar concerns in that errors can ultimately result in fatalities. There are parallels in the …

Left Ventricular Assist Devices: Engineering Design Considerations, Marwan A. Simaan, Eduardo Divo, George Faragallah, Yu Wang

Publications

Patients with end-stage congestive heart failure awaiting heart transplantation often wait long periods of time (300 days or more on the average) before a suitable donor heart becomes available. The medical community has placed increased emphasis on the use of Left Ventricular Assist Devices or LVADs that can substitute for, or enhance, the function of the natural heart while the patient is waiting for the heart transplant (Poirier, 1997; Frazier & Myers, 1999). Essentially, a rotary LVAD is a pump that operates continuously directing blood from the left ventricle into the aorta by avoiding the aortic valve. Generally speaking, the …
