Journal ArticleDOI
TL;DR: De and X. Lefevre as discussed by the authors outline the principles of a proposed collision avoidance aid based on the concept of a ship's "room to manoeuvre" in the presence of the vessels' or hazards to navigation.
Abstract: In this paper, by T. Degre and X. Lefevre of the Organisme de Recherches Informatiques et Operationnelles appliques a la Navigation (ORION), the authors outline the principles of a proposed collision avoidance aid based on the concept of a ship's ‘room to manoeuvre’ in the presence of the vessels' or hazards to navigation and a corresponding bridge display.

TL;DR: In this paper, the Fast-Time Encounter Generator (FTEG) is used as a test bed to analyze and validate Aircraft Separation Assurance (ASA) algorithms at the Federal Aviation Administration (FAA) Technical Center in Pomona, New Jersey.
Abstract: This paper describes a digital discrete simulation system which is used as a test bed to analyze and validate Aircraft Separation Assurance (ASA) algorithms at the Federal Aviation Administration (FAA) Technical Center in Pomona, New Jersey. This dynamic interactive system, the Fast-Time Encounter Generator (FTEG), provides special computer simulation capabilities required to support the evaluation of the Active Beacon Collision Avoidance System (BCAS). As part of the overall BCAS project, the FAA Technical Center is utilizing the FTEG to investigate the performance of the collision avoidance logic. This use and some of the results of the investigations will be discussed. Other uses of the FTEG will also be presented.

TL;DR: In this article, the authors investigated the nature and characteristics of problems involving dissemination of weather information, use of this information by pilots, its adequacy for the purpose intended, the ability of the air traffic control system to cope with weather related incidents, and various aspects of pilot behavior, aircraft equipment, and NAVAIDS affecting flights in which weather figures.
Abstract: Consideration is given to the nature and characteristics of problems involving dissemination of weather information, use of this information by pilots, its adequacy for the purpose intended, the ability of the air traffic control system to cope with weather related incidents, and the various aspects of pilot behavior, aircraft equipment, and NAVAIDS affecting flights in which weather figures. It is concluded from the study that skill and training deficiencies of general aviation pilots are not major factors in weather related occurrences, nor is lack of aircraft equipment. Major problem causes are identified with timely and easily interpreted weather information, judgement and attitude factors of pilots, and the functioning of the air traffic control system.

TL;DR: In this paper, the authors describe a set of equipment and procedures which can accomplish the necessary coordination at a low enough cost to enable widespread deployment, using highly reliable technology which is currently available.
Abstract: Collisions between ships are relatively rare, but entail considerable damage to property and, frequently, loss of life. Most of the collisions occur when visibility is limited, due to darkness or weather. Numerous studies have concluded that only through coordinated maneuvers of both ship can collisions be effectively avoided. There are currently no techniques available to accomplish the necessary coordination at a low enough cost to enable widespread deployment. This paper describes a set of equipment and procedures which can accomplish this, using highly reliable technology which is currently available.
