Available in PDF, EPUB and Kindle. Book excerpt: A study was made to evaluate competency of pilots trained in aircraft having a stability augmentation system. This is to determine the necessity of issuing restricted certificates to private pilots if they are unable to pass the private flight check by manual operation of controls. This project was to train five students to required flight performance for a private pilot certificate in a Cherokee-140 equipped with the Mitchell AK-153 Stability Augmentation System. When the students reached private pilot proficiency, they were given three flight checks. The first with the system on, the second with it off, and the third in a different aircraft without the stability system. All students passed the checks without difficulty. The results of the project indicate that all students reached private pilot proficiency in an average time. The stability system had no particular effect on the students' control of the aircraft with or without visual references. Therefore, it would seem unnecessary to issue restricted pilot certificates.

Download or read book The Design of Stability Augmentation Systems for Decoupling Aircraft Responses written by Rhall Edward Pope and published by . This book was released on 1972 with total page 152 pages. Available in PDF, EPUB and Kindle. Book excerpt: Tactical aircraft with STOL capability exhibit undesirable coupled response during the landing phase of flight. A simplified method for designing a stability augmentation system which eliminates the coupling effects is demonstrated. The method is based on Gilbert's decoupling theory which utilizes a feedback control law to obtain a set of single input, single output subsystems. The augmentation system can be designed to provide either command rate or command angle authority in the three rotational axes. Analyses is facilitated through the use of two computer programs, the first of which determines the class of control laws which will decouple a system. The second computer program determines, through transient response analysis, the values of the transfer function parameters required to satisfy response criteria. The results of a piloted simulation which analyzed several decoupled configurations is also presented. (Author).

This book was released on 1966 with total page 164 pages. Available in PDF, EPUB and Kindle. Book excerpt: The results of a flight evaluation of a Stability Augmentation System (SAS) for light airplanes are reported and discussed. Twenty-six non-instrument rated private and commercial pilots, whose distribution by rating and flight hours was typical of those who are involved in IFR disorientation accidents, and five instrument rated commercial pilots were flown. Quantitative measures of the bank angle, airspeed, altitude and heading were recorded during a series of planned VFR and IFR tasks with the SAS ON and OFF. Qualitative data were obtained from the subject pilots by questionnaire and the recorded observations of the safety pilot. A statistical analysis was made of the differences in pilot performance during system ON and system OFF operation. It was shown that the stabilizing effects of SAS, although not sufficient in itself to prevent this type of accident, significantly improved the non-instrument rated pilot's ability to maintain control of the airplane during an inadvertent encounter with IFR conditions.

Available in PDF, EPUB and Kindle. Book excerpt: The report evaluates the feasibility and desirability of a fluidic Automatic Flight Control System. The study is carried out in four parts: (1) a description of the basic flight control system and fluidic components; (2) the definition and requirements for an automatic flight control; (3) a proposed fluidic system; and (4) an evaluation of the proposed system with a comparison with an existing Automatic Flight Control System. The Automatic Flight Control System (AFCS) to be implemented consists of open loop damping (OLD) systems, stability augmentation systems (SAS) and an autopilot. Each mode of control - pitch, yaw, roll, and translation - is similar in function. The portion of the complete AFCS chosen for implementation is the pitch axis of a fly-by-wire system. For the Fluidic system under consideration in this report, a fluid signal transmission system is the equivalent of the conventional fly-by-wire system. The proposed fluidic control has hydraulic OLD and SAS, and a pneumatic autopilot. These fluids were chosen primarily for compatibility with the power drive and response, respectively. The reliability comparison, which for the fluidic components was based on estimated failure rates, shows better performance for the fluidic system.

Available in PDF, EPUB and Kindle. Book excerpt: An experiment was performed to investigate the proficiencies of student pilots trained to the required flight performance for a private pilot's certificate in airplanes incorporating a stability augmentation system. Two selected flight schools trained five subjects each. Upon reaching the required proficiency, each student was given three separate flight checks with and without the use of the stability systems and an additional check in a same class airplane not having a stability system. Results indicated pilot competence was not effected one way or another by training with such a system. All students met the required performance standards and were issued unlimited private pilots certificates. (Author).

This book was released on 2012-12-06 with total page 335 pages. Available in PDF, EPUB and Kindle. Book excerpt: Masters Theses in the Pure and Applied Sciences was first conceived, published, and disseminated by the Center for Information and Numerical Data Analysis and Synthesis (CINDAS) * at Purdue University in 1957, starting its coverage of theses with the academic year 1955. Beginning with Volume 13, the printing and dissemination phases of the activity were transferred to University Microfilms/Xerox of Ann Arbor, Michigan, with the thought that such an arrangement would be more beneficial to the academic and general scientific and technical community. After five years of this joint undertaking we had concluded that it was in the interest of all con cerned if the printing and distribution of the volume were handled by an international publishing house to assure improved service and broader dissemination. Hence, starting with Volume 18, Masters Theses in the Pure and Applied Sciences has been disseminated on a worldwide basis by Plenum Publishing Cor poration of New York, and in the same year the coverage was broadened to include Canadian universities. All back issues can also be ordered from Plenum. We have reported in Volume 26 (thesis year 1981) a total of 11 ,048 theses titles from 24 Canadian and 21 8 United States universities. We are sure that this broader base for these titles reported will greatly enhance the value of this important annual reference work. While Volume 26 reports theses submitted in 1981, on occasion, certain univer sities do report theses submitted in previous years but not reported at the time.
