Projeto conceitual de uma aeronave de aviação geral e análise de compromissos / A conceptual design of general aviation aircraft and analysis of commitmentsAbdalla, Alvaro Martins 19 November 2004 (has links)
Busca-se encontrar a solução de compromissos para o desenvolvimento de uma aeronave multifuncional, de aviação geral, a pistão, que atenda às necessidades do mercado brasileiro e cujas características de desempenho estejam próximas ou superiores às das aeronaves típicas da aviação geral que operam nos Estados Unidos e Brasil. O objetivo principal do trabalho consistiu em desenvolver uma metodologia para projetos conceituais de aeronaves de pequeno porte e de uma família de aeronaves de forma que a geradora da família possa ser facilmente convertida em configurações diferentes, conservando o maior número de partes em comum, mantendo as características de desempenho almejadas e cumprindo com os requisitos de certificação impostos para a categoria. Apresentam-se definições, conhecimentos e técnicas na área de projetos aeronáuticos e descrevem-se de forma sucinta os aspectos mais importantes que envolvem o projeto conceitual. Em seguida é exposta a metodologia utilizada e são definidos os objetivos e os compromissos. Finalmente são apresentadas tabelas geradas pelo software PCA-Projeto Conceitual de Aeronaves e gráficos contendo as caracterizações onde se enquadra o objeto de estudo, a discussão e as conclusões da investigação. / The purpose of this work is to derive compromise solutions for the conceptual design of a general aviation aircraft, aimed to fulfill the requirements of the brazilian market. Fitted with a conventional piston engine, such aircraft should however sport technical and flight characteristics which are equal or better than those found on existing typical general aviation aircraft in operation both in Brazil and United States. The main objective of the thesis consisted of development of methodology for the conceptual design of a family of light aircraft so that the \"core aircraft\" can be regarded as a platform for the derivation and conversion to any of the family members - two, four and six - seats. Commonality of parts to the highest degree possible, achievement of a set of performance and efficiency goals and compliance with the existing certification requirements for the aircraft category are some of the main project drivers. The work presents the major topics definitions, the main specific techniques required in the subject of aircraft conceptual design followed by the key aspects associated with such an undertaking. The employed methodology is presented next, followed by the set objectives and compromise solutions so reached. Finally, the results for the three aircraft family are presented both graphically and in a set of data tables complemented by a few print-outs of the computer screen outputs generated by the software developed - PCA, which embodies the whole work carried out and can be used for the further improvements in the future. The conclusions present some critical analysis points and suggestions for the future work.

DETECTING GA AIRCRAFT HAZARDOUS STATE USING A LOW-COST ATTITUDE AND HEADING REFERENCE SYSTEMArpan Chakraborty (5930570) 17 January 2019 (has links)
General Aviation (GA)
accidents constitute the majority of aviation related accidents. In the United
States, there have been over 7,000 GA accidents compared to 190 airline
accidents in the last 8 years. Flight data analysis has helped reduce the
accident rate in commercial aviation. Similarly, safety analysis based on
flight data can help GA be safer. The FAA mandates flight data recorders for
multi-engine and turbine powered aircraft, but nearly 80% of General Aviation
consists of single engine, of which only a small portion contain any form of
data recording device. GA aircraft flight data recorders are costly for
operating pilots. Low-cost flight recorders are few and rarely used in GA
safety analysis due to lack of accuracy compared to the certified on-board
equipment. In this thesis, I investigate the feasibility of using a low-cost Attitude
and Heading Reference System (AHRS) to detect hazardous states in GA aircraft. I
considered the case of roll angles and found that the low-cost device has
significant measurement errors. I developed models to correct the roll angle
error as well as methods to improve the detection of hazardous roll angles. I devised
a method to evaluate the time accuracy along with the angle accuracy and showed
that despite the errors, the low-cost device can provide partial hazardous
state detection information.

Supporting general aviation pilots during rerouting process due to sudden weather changesTokadli, Guliz 21 September 2015 (has links)
General aviation pilots need different types of flight information in order to follow events and the changes related to the aircraft environment while flying. However, general aviation cockpits have some limitations as space to install flight displays to provide flight information beyond the basics to the pilot. Additionally, more sophisticated instrumentation is often expensive to install and maintain. With the development of the tablet-based software applications (such as ForeFlight, WingX Pro7 or Garmin Pilot applications for iPad), general aviation pilots have started to use them instead of paper documentation. These software applications provide essential flight information such as weather forecast, aviation charts, flight documents, etc. Unfortunately, the expectations for their capabilities are changing with the increased demand and popularity of these software applications. Therefore, these flight planning software applications are compared to find what is missing and what have not met the expectation of pilots.
First, how the software applications support their decision-making process was described and demonstrated to choose the appropriate flight parameters to change flight path while handling with the other cockpit responsibilities. Finally, these design requirements were validated via HITL tests in a part-task flight simulator. The results provided that the suggested design requirements are found highly useful for both novice and expert general aviation pilots. Specifically, novice general aviation pilots might be able to get visualization to compare real-time weather and weather forecast, and then they might gain experience to improve their success for a in-flight re-planning. On the other side, expert pilots might prefer to use this system if they fly an airspace which they are not familiar to weather features of that region.

Defining Airport Operational Sustainability for the U.S. General Aviation AirportsYue Gu (6635894) 15 May 2019 (has links)
<p>While
the general public may be familiar with commercial airports, there are
thousands of small General Aviation (GA) airports serving communities across
the United States. Many of these airports are under pressure to survive and to
bring in more revenue without impinging on the community
and environment. Many organizations and governmental agencies such as the
Federal Aviation Administration (FAA), now recognize the value of sustainable
development and importance of operation to airport sustainability. Achieving
operational sustainability is a means that may help airports on sustainable
development and has positive impacts on airports’
economic viability, natural resource conservation, and social responsibility. However,
airport operational sustainability is rarely defined in a consistent,
measurable manner (Johnson & Gu, 2017).</p><p><br></p><p>This study
explored the understanding of airport operational sustainability among five GA
Regional and Local airports. Based on the findings, a new definition of airport
operational sustainability for U.S Regional and Local GA airports was proposed.
A set of performance metrics for airport
operational sustainability was developed. The outcomes of the study may help
airport shareholders contribute to airport sustainability planning through a
better understanding of sustainability principles<a>. A set
of performance metrics for airport operational sustainability </a>may be used
to quantify the sustainability achievements of airports and help airports
measure their performance.</p><p></p>

EVALUATION MODELING FOR ENERGY MANAGEMENT IN GENERAL AVIATION AIRPLANESAlexandra Courtney Kemp (16648827) 02 August 2023 (has links)
<p>The dissertation research was conducted to examine articles, research, and studies that have been collected in recent years to understand energy management for general aviation airplane pilots. The experiment was broken down into four phases with control and treatment groups which have evaluated the real-world problem of energy management in aviation. The four phases were to fly a flight profile, evaluate the energy state of the airplane within the flight by video, fly the same flight profile again, and a post-flight interview with the pilots. The idea of this experiment was to recognize the lack of understanding in energy management in pilots, build a conceptual model, and lastly verify and validate Phase II of the model by utilizing previous studies and research. Additionally, the three main goals were to assess the ability to interpret energy management, assess the ability to control the aircraft, and lastly, to interview for perception of energy management. The data was collected on the flight training device’s G1000, and the researcher analyzed the data using R, Minitab, Excel, and NVivo. The research provided ideas for creating a future model to evaluate energy management, validated by testing Phase II of the model to understand assessing energy management in real time, and interviewed pilots on their experiences with energy management, identified gaps in general aviation research, and suggested methods of how to facilitate understanding of energy management.</p>

General Aviation Demand Forecasting Models and a Microscopic North Atlantic Air Traffic Simulation ModelLi, Tao 06 January 2015 (has links)
This thesis is focused on two topics. The first topic is the General Aviation (GA) demand forecasting models. The contributions to this topic are three fold: 1) we calibrated an econometric model to investigate the impact of fuel price on the utilization rate of GA piston engine aircraft, 2) we adopted a logistic model to identify the relationship between fuel price and an aircraft's probability of staying active, and 3) we developed an econometric model to forecast the airport-level itinerant and local GA operations. Our calibration results are compared with those reported in literature. Demand forecasts are made with these models and compared with those prepared by the Federal Aviation Administration. The second topic is to model the air traffic in the Organized Track System (OTS) over the North Atlantic. We developed a discrete-time event model to simulate the air traffic that uses the OTS. We proposed four new operational procedures to improve the flight operations for the OTS. Two procedures aim to improve the OTS assignments in the OTS entry area, and the other two aim to benefit flights once they are inside the OTS. The four procedures are implemented with the simulation model and their benefits are analyzed. Several implementation issues are discussed and recommendations are given. / Ph. D.
