This book was released on 1989 with total page 20 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report presents a brief description of the derivation of the collision risk equations for the use on the vertical separation Midair Collision Simulation Risk Model. It also describes the estimation of the Collision Risk Model parameters for the current 2000-foot standard and the proposed 1000-foot planned vertical separation standard. The model itself consist of specialized computer programs and systematic procedures that realistically and economically simulate aircraft flight-planned movements in the National Airspace System (NAS). These aircraft movements are based on flight plans and tracking data transmitted to Central Flow Control FAcility (CFCF) from all the 20 centers that make up the NAS. The task is to find the frequency, Na, with which a pair of aircraft flying at and above flight level (FL)290 would, by flight-planned intent, be proximate (near each other) in the NAS. The purpose of this mathematical model is to make a quantitative judgement about the safety of the proposed 1000-foot vertical separation, and provide an estimate of the risk of midair collision due to the loss of 1000-foot planned vertical separation. As the result of this first phase of the study, it is recommended that the model be enhanced to do the following: 1) step climbing, and 2) point-to-point navigation. Keywords: Tracking system; Proximity shell; Separation vectors; Collision slab; Central flow.

This book was released on 2020-03-18 with total page 176 pages. Available in PDF, EPUB and Kindle. Book excerpt: One of the most complex challenges for the future of aviation is to ensure a safe integration of the expected air traffic demand. Air traffic is expected to almost double its current value in 20 years, which cannot be managed without the development and implementation of a safe air traffic management (ATM) system. In ATM, risk assessment is a crucial cornerstone to validate the operation of air traffic flows, airport processes, or navigation accuracy. This book tries to be a focal point and motivate further research by encompassing crosswise and widespread knowledge about this critical and exciting issue by bringing to light the different purposes and methods developed for risk assessment in ATM.

Download or read book Rare Event Simulation using Monte Carlo Methods written by Gerardo Rubino and published by John Wiley & Sons. This book was released on 2009-03-18 with total page 278 pages. Available in PDF, EPUB and Kindle. Book excerpt: In a probabilistic model, a rare event is an event with a very small probability of occurrence. The forecasting of rare events is a formidable task but is important in many areas. For instance a catastrophic failure in a transport system or in a nuclear power plant, the failure of an information processing system in a bank, or in the communication network of a group of banks, leading to financial losses. Being able to evaluate the probability of rare events is therefore a critical issue. Monte Carlo Methods, the simulation of corresponding models, are used to analyze rare events. This book sets out to present the mathematical tools available for the efficient simulation of rare events. Importance sampling and splitting are presented along with an exposition of how to apply these tools to a variety of fields ranging from performance and dependability evaluation of complex systems, typically in computer science or in telecommunications, to chemical reaction analysis in biology or particle transport in physics. Graduate students, researchers and practitioners who wish to learn and apply rare event simulation techniques will find this book beneficial.

Download or read book Advances in Air Navigation Services written by Tone Magister and published by BoD – Books on Demand. This book was released on 2012-08-01 with total page 190 pages. Available in PDF, EPUB and Kindle. Book excerpt: Provision of air navigation services entered a new era of performance scheme. The performance scheme provides binding targets on four key performance areas of safety, capacity, environment and cost-efficiency. It is imposed that targets are fully achieved, but it is not prescribed how, this being typical for the performance based and goal oriented regulation. Those key performance areas are interlaced by proportional and inversely proportional interdependencies. Namely, for example and simplified into one sentence; if one aims to increase sector capacity with existing human resources (constant staff costs) and not investing into the technology (constant support cost) to achieve improved cost-efficiency of service provision, the resulting overloaded system might unlock the Pandora box of latent safety issues. Since failure is not an option, we - the general, migrating and traveling public, airspace users, airport operators, air navigation services providers and the economy - will gain attaining the goals of performance scheme in the process. However, un-answered cardinal question is what is the winning strategy? This book provides do-not-forget-peculiarities insight into the elements of new business model of air navigation services provision as evolution of the latter became essential.
