Managing Safety Risks In Airline Maintenance Outsourcing, Rajee Olaganathan Dr., Mark Miller Dr., Bettina M. Mrusek Dr.
International Journal of Aviation, Aeronautics, and Aerospace
The U.S aviation industry faced severe financial losses after the 9/11 incident. The financial loss that occurred between 2000 and 2009 in the U.S. alone was $54 billion dollars. One of the operational strategies adopted by air carriers to overcome this hurdle was to outsource aircraft maintenance. Initially, this was accomplished in both home and off-shore locations. Unionized labor relations in the US ultimately forced these organizations to outsource to non-unionized labor sources in foreign countries. However, due to the upsurge in accidents and incidents that resulting from maintenance failures, the concept of outsourcing maintenance became a subject of debate …

Low Level Turbulence Detection For Airports, Anthony O' Connor, Derek Kearney
International Journal of Aviation, Aeronautics, and Aerospace
Abstract—— Low level wind shear and turbulence present a serious safety risk to aircraft during the approach, landing and take-off phases. Despite many advances in on-board and ground based warning systems. Wind shear remains a formidable force that coupled with a microburst can overpower any aircraft. Aviation reports have concluded that pilots need to have improved information in relation to tailwinds, wind shear and wind variations on approach and during the landing phases. Low level wind shear continues to cause disruption, delays and contribute to aircraft crashes. As recently as 2016, two Boeing aircraft crashed while attempting a Go-around …
The Application Of Signal Detection Theory Principles To Aircraft Certification, John M. Maris Ph.D, Alexander V. Ilyin Ph.D
The Application Of Signal Detection Theory Principles To Aircraft Certification, John M. Maris Ph.D, Alexander V. Ilyin Ph.D
International Journal of Aviation, Aeronautics, and Aerospace
This paper presents the application of Signal Detection Theory (SDT) concepts to the certification of optional systems that provide operational or system safety benefits. The method and analysis yield quantitative requirements for the system performance that account for the risks and benefits of the potential system. This is in contrast to the standard certification approach which only focuses on Failure Conditions, and does not examine potential system benefits. A case study of an aircraft spotter on an electronic moving map illustrates that substantial safety improvements may be achieved even with the relatively low levels of software reliability associated with Commercial …

Building Evidence The Federal Aviation Administration's Uas Safety Strategy Needs Improvement, Ryan J. Wallace, Tom Haritos, John Robbins
International Journal of Aviation, Aeronautics, and Aerospace
The growth of unmanned aircraft operations within the National Airspace System (NAS) reveal an uptick of alarming safety indicators that suggest unmanned aircraft system (UAS) regulatory policy may require adjustment. Recent reports of aircraft collisions with UAS, an increase in pilot-reported near-misses, and research findings that indicate UAS platforms are capable of causing structural damage to aircraft suggest safe and effective UAS integration may not be proceeding as planned. The authors examine several safety indicators within the context of Heinrich’s Triangle to reveal the UAS industry’s susceptibility to evolving safety-related problems.

Quantitative Examination And Comparison Of Altimetry Rules-Of-Thumb For General Aviation, Thomas A. Guinn
Quantitative Examination And Comparison Of Altimetry Rules-Of-Thumb For General Aviation, Thomas A. Guinn
International Journal of Aviation, Aeronautics, and Aerospace
General aviation rules of thumb (ROTs) for density altitude and true altitude are examined and developed. Both ROTs originate from the same basic principle of hydrostatic balance, but differ significantly in the assumptions made regarding the atmospheric temperature profile. While the ROT for DA assumes a standard atmospheric vertical temperature lapse rate, the ROT for true altitude requires information regarding the observed layer-mean temperature of the atmosphere. Since the layer-mean temperature between the aircraft and the surface is typically unknown, it must be inferred from the temperature at a single level by again assuming a linear lapse rate. This method …
