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 …

Reliability Of Eyewitness Reports To A Major Aviation Accident, Dave English, Michael Kuzel

International Journal of Aviation, Aeronautics, and Aerospace

There is a paucity of studies on the reliability of eyewitness reports to aviation crashes. We examine witness statements to a widely observed major airline accident to determine if reported accident investigator distrust of details in eyewitness reports is supported by empirical evidence. The extensive archival witness record (N > 300) of a wide-body airliner crash in clear daylight conditions is subjected to statistical analysis to test eyewitness reliability. Even with over 200 witnesses within a three square kilometre (1.6 square mile) area answering a binary observation question, the variance is sometimes high enough to preclude forming statistically significant conclusions …

Something Old Is New Again: Airline-Airport Consortia And Key Stakeholder Benefits, Janet K. Tinoco, Brian W. Sherman

Management, Marketing and Operations - Daytona Beach

Although consortia in the aviation sector predate deregulation by decades, this type of cooperative agreement, particularly in the airline industry, is experiencing a resurgence of interest from industry participants and academia. Airlines are searching for new innovative ways to reduce costs while airports are searching for private partners to improve terminal facilities and equipment and update services. Passengers, on the other hand, continue to balance price versus performance in their travel experience. This empirical research study finds evidence of positive influences of airline consortia to all key stakeholders; however the majority of benefit appears to be felt by the airlines …

A Descriptive Analysis Of Public Comments Submitted In Response To Notice Of Proposed Rules On Air Carrier Pilot Qualification, Amy Chaffee Doolittle

Doctoral Dissertations and Master's Theses

In 2009, the crash of Colgan Flight 3407 in Buffalo, NY raised concerns regarding the adequacy of current pilot qualification standards for entering air carrier operations. In response, the U.S. Congress enacted Public Law 111-216, which requires a pilot to hold an Airline Transport Pilot (ATP) certificate in order to be qualified as a flight crewmember under 14 CFR, part 121, and also allows the Federal Aviation Administration (FAA) to modify the requirements to obtain an ATP certificate. In February 2012, the FAA issued a Notice of Proposed Rulemaking (NPRM) outlining these requirements and calling for public comments on the …

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

Publications

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 …
