Accident Rates, Phase Of Operations, And Injury Severity For Solo Students In Pursuit Of Private Pilot Certification (1994–2013), Douglas Boyd, Peter Dittmer

Journal of Aviation Technology and Engineering

Flight training accidents constitute 14% of general aviation accidents. Herein we determined the rates, injury severity, and phase of flight for primary student solo accidents/incidents (mishaps) in Cessna 172 aircraft.

Mishaps over the period spanning 1994–2013 were identified from the NTSB database. Student population data were from the FAA. Statistics employed proportion tests, Poisson distribution, and Mann-Whitney tests.

Across the study period, 598 mishaps were identified. While the mishap rate increased nearly two-fold between 1994/1997 and 2002/ 2005, a 35% decline was evident thereafter. Nevertheless, no statistical difference in mishap rates was evident between the initial and current periods. Over …

Flight Emergency Advice Works Just As Well Back On The Ground, Carolyn Massiah

UCF Forum

Save yourself first!

This one sentence is a valuable piece of advice I wish I had received and fully embraced so much earlier in life. In fact, it is still a notion that I struggle with because it is one that sounds selfish in nature. However, now more than at any other point in my life, I realize that in order to be selfless and to be able to assist others, you must first truly work on thinking of your own self first.

Abstract

High Altitude Ballooning and The Effect of Temperature on Balloon Ascent Rate.

Christopher Young

High-altitude balloons are unmanned balloons, usually filled with helium or hydrogen, that after release, ascend into the stratosphere, generally attaining an altitude of between 60,000 to 100,000 feet. The balloon payload includes scientific experiments on organisms, equipment to study radiation, temperature, ultra- violet radiation, and pressure. The balloon flights and experiments are logged by means of video devices and are tracked from the ground through multiple tracking devices. The effect of temperature on the ascent rate of the balloon could change how the balloon expands …

ERAU Prescott Aviation History Program

Europe to the U.S. in less than 3 ½ hours at 60,000 feet and Mach 2! The Concorde was one of world’s most recognized aircraft and a technological marvel. Learn what it was like to fly it from a pilot who did so for 15 years. Capt. Hutchinson was a Concorde route check airman and a British Airways pilot selector. He also worked with BBC television as a presenter of Airshow programmes and helped promote the Concorde/QE2 travel packages. What a way to travel!

Applying The Technology Acceptance Model To Understand Aviation Students’ Perceptions Toward Augmented Reality Maintenance Training Instruction, Yu Wang, Amadou Anne, Tim Ropp

International Journal of Aviation, Aeronautics, and Aerospace

Augmented Reality (AR) Technology, since its inception, has been enhanced significantly by software and hardware developers, and has been widely utilized in various fields such as manufacturing, entertainment, architecture, commerce and education. In recent years, maintenance instructions developed on the basis of AR technology have demonstrated their potential to positively impact maintenance training and technical tasks in aviation. Features of AR maintenance instructions include interactive content, user-friendly operation interface, enhanced visualization and real-time data feeds. The researchers conducted a case study of forty-one aviation maintenance students at a Midwestern university. The purpose of this study was twofold: to evaluate the …

Designing Fixed-Base Operations Utilizing Systems Engineering Principles, Ross L. Stephenson Jr., David A. Carroll

Journal of Aviation Technology and Engineering

There are currently over 3,200 fixed-base operations (FBOs) conducting business in the United States attempting to meet the demands of FAA Part 91, Part 135, and a limited number of Part 121 operations. With the US economy slowly climbing out of the trough during 2013, the utilization of fixed-base operations has become more attractive and economical to the corporate business and the affluent recreational traveler. Despite the increased flight activities utilizing the services of fixed-base operators, keen competition, rising fuel cost, and the economies of scale recognized by large FBO franchises significantly erode the profitability and sustainability of smaller FBOs. …

Investigation Into Unmanned Aircraft System Incidents In The National Airspace System, Rohan S. Sharma

International Journal of Aviation, Aeronautics, and Aerospace

With the promulgation of Federal Aviation Regulations for small unmanned aircraft systems, the volume of unmanned flight operations is expected to increase, which demands an analysis of potential hazards to the National Airspace System. Descriptive statistics were used to investigate reports archived in the Aviation Safety Information and Analysis and Sharing system involving unmanned aircraft systems, as well as the FAA UAS Sightings Reports database. The frequency of reports involving airspace violations, and Near Mid-air Collisions by unmanned aircraft systems as well as an analysis of the location, sponsor category, phase of flight, altitude, and airspace type in which the …

Automotive-Inspired Inceptors And Control Laws Designed For Simplified Piloted Flight, Kashif Ali

Doctoral Dissertations and Master's Theses

This thesis details the development of a simulator-based experiment in automotive- inspired controls for aircraft. The goal is to fuse the ease of drivability of a car with the flight of an aircraft. A standard automotive control hardware setup coupled with fly-by-wire control laws will allow non-pilots to fly a plane using their familiarity with driving a car. A mathematical description of the control law logic and controller implementation is presented and the human subjects' performance is measured from data collected during experimental testing of the simulator. Preliminary results indicate that non-pilots improve their path-tracking performance and reduce control activity …

Safety Assurance Of Non-Deterministic Flight Controllers In Aircraft Applications, Alfonso Noriega

Doctoral Dissertations and Master's Theses

Loss of control is a serious problem in aviation that primarily affects General Aviation. Technological advancements can help mitigate the problem, but the FAA certification process makes certain solutions economically unfeasible. This investigation presents the design of a generic adaptive autopilot that could potentially lead to a single certification for use in several makes and models of aircraft. The autopilot consists of a conventional controller connected in series with a robust direct adaptive model reference controller. In this architecture, the conventional controller is tuned once to provide outer-loop guidance and navigation to a reference model. The adaptive controller makes unknown …

Can Flight Data Recorder Memory Be Stored On The Cloud?, Yair Wiseman

Journal of Aviation Technology and Engineering

Flight data recorders (FDRs, or black boxes) generate data that is collected on an embedded memory device. A well-known difficulty with these devices is that the embedded memory device runs out of space. To avoid getting into this problematic situation, the software of the FDR is designed to operate in a watchful mode, constantly working to minimize the use of memory space; otherwise a larger FDR would be needed. However, larger FDRs can be a problem because they have very rigorous requirements; thus, enlargement is costly. Outcomes of this research include the recommendation to send FDR data to a remote …
