Effects Of Automation On Aircrew Workload And Situation Awareness In Tactical Airlift Missions, David R. Meyer

Theses and Dissertations

In tactical aviation, decision superiority brought upon by high situation awareness remains the arbiter of combat effectiveness. The advancement of sophisticated avionics and highly automated cockpits has allowed for the reduction of aircrew size, and in certain platforms, removal of the crew from the aircraft entirely. However, these developments have not reduced the complex and dynamic interaction between situation awareness and crew workload. While many predictive and experimental methods of evaluating workload exist, situation awareness can only be measured by conducting trials with human operators in a functional prototype. This thesis proposes an innovative methodology to predicatively determine situation awareness …

Market Analysis For Small And Mid-Size Commercial Turboprop Aircraft, Vitaly Guzhva, Tamilla Curtis, Vladislav Borodulin

Dr. Tamilla Curtis

Recent fuel price volatility and growing concerns about the efficiency of regional jets have led to a revival of large turboprop aircraft as efficient passenger carriers on short-haul regional routes. However, the overall market for smaller turboprops is much less defined as it is characterized by a plethora of small commuter and niche operators in addition to regional carriers. Since most small and mid-size turboprop manufacturers have gone bankrupt or discontinued production due to some other reasons, current operators of this aircraft class are left with aging fleets that would need to be replaced by 2020-2030. This paper assesses the …

Improving The Integration Of Launch And Reentry Operations Into The National Airspace System, Gwendolyn Mazzotta, Daniel P. Murray

Space Traffic Management Conference

With increasing commercial space activities occurring in the National Airspace System, the FAA has identified a need for more efficient management of the NAS with respect to commercial space operations. Current methods for integration of aviation and space activities employ a segregation approach, in which hazard areas are constructed around launch and reentry operations and sections of airspace are closed to other users. Mission objectives and vehicle characteristics dictate the extent of the closure in terms of location, duration, and volume of airspace affected. Launches, reentries, and other operations have an effect on other NAS stakeholders, causing delays, changes to …

Safe Operations Above Fl600, Lt. Col. Stephen Hunter

Space Traffic Management Conference

Safe Operations Above FL600

Abstract

With the increase in likelihood of near-term development of revenue-generating point-to-point suborbital flights and the increase in high-altitude-long-endurance commercial operations above FL600, the criticality of addressing operations above class A airspace has never been more pressing. While the Federal Aviation Administration describes the National Airspace System, it doesn’t offer a description that includes a top. Technological, physiological, physical and administrative limitations have relegated most air operations to FL600 and below. As that changes, previous work on Space Traffic Management (STM) concepts begin to take on new life and add to sincere considerations for adaptation or …

A multi linear modeling process was applied on the two categories to determine whether there is …

The Implementation Of Safety Management Systems In Maintenance Operations, Daniel H. Siao

Aviation / Aeronautics / Aerospace International Research Conference

Literature for Safety Management Systems (SMS) that apply to flight operations is abundant, but there is a limited supply of SMS-related literature for maintenance operations. The FAA emphatically states on its website that safety is the “foundation of everything we do,” and this is reflected in the FAA Flight Plan, where the general tenor of this document is increasing safety. However, while there is ample mention of flight safety, there is no mention of maintenance-related safety in the FAA Flight Plan.

Even though the benefits of SMS are well established, it is difficult for maintenance facilities—especially small repair stations—to justify …

Is “Green Dot” Always The Optimum Engines-Out Glide Speed On The Airbus A320 Aircraft?, Kivanc A. Avrenli, Barry J. Dempsey

Journal of Aviation/Aerospace Education & Research

The dual-engine failure checklist of the Airbus A320 states that the optimum airspeed at which the aircraft can be flown is the “green dot” speed when an engine restart is considered impossible. This is because the “green dot” speed maximizes the power-off glide range in wings-level flight. However, it is not known whether the “green dot” speed would still be the optimum airspeed if the power-off landing maneuver primarily consists of sharp turns. The objective of this study is to find out the optimum power-off glide speed for the A320 if the emergency landing maneuver primarily requires sharp turns rather …

How System Errors Affect Aircrew Resource Management (Crm), Justin Y. Adkins, Kevin Macg. Adams, Patrick T. Hester

Engineering Management & Systems Engineering Faculty Publications

System errors, both mechanical and human in nature, can have a grave effect on aircrew judgement in flight. The effects of these errors can be massively compounded during emergency situations. Crew Resource Management (CRM) is an important process aircrews can utilize to minimize risks and enhance assessments. The employment of this technique can be validated by aviation mishaps over the last three decades and how system errors increased the probability of the incident occurring. Suggestions can be made to further prevent similar accidents from occurring in the future utilizing historical aeronautical records. This paper outlines an approach by which systems …
