It is anticipated that a greater number of Flight Data Analysis Programs will lead to significantly greater safety levels through analysis of critical event sets and incidents. Action: The FDAP working group is requesting support for greater implementation of FDAP/FDMP throughout the Pan American Regions and consideration of new ICAO standards through the actions outlined in Section 4 of this working paper. Strategic Safety Objectives: References: Annex 6 ‐ Operation of Aircraft, Part 1 sections as mentioned in this working paper RASG‐PA ESC/28 ‐ WP/09 presented at the ICAO SAM Regional Office, 4 to 5 May 2017. 1.

Rourkela Institute of Management Studies, Rourkela 2 Aviation Executive Summary India is one of the fastest growing aviation markets in the world. With the liberalization of the Indian aviation sector, the industry had witnessed a transformation with the entry of the privately owned full service airlines and low cost carriers. The sector has seen a significant increase in number of domestic air travel passengers. Some of the factors that have resulted in higher demand for air transport in India include the growing middle class and its purchasing power, low airfares offered by low cost carriers, the growth of the tourism industry in India, increasing outbound travel from India, and the overall economic growth of india.

  • A Conceptual Model for the Computer Simulation of Air Traffic Control Radar Surveillance Systems
    A Conceptual Model for the Computer Simulation of Air Traffic Control Radar Surveillance Systems Reza Adibnia B.A.Sc. (Electrical Engineering), Sharif University of Technology, 1999 , THE THESIS SUBMITTED IN PARTIAL FULFILMENT OF THE REQUIREMENTS FOR THE DEGREE OF MASTER OF APPLIED SCIENCE in THE FACULTY OF GRADUATE STUDIES ( ELECTRICAL AND COMPUTER ENGINEERING ) THE UNIVERSITY OF BRITISH COLUMBIA September 2005 © Reza Adibnia, 2005 Abstract The objective of this work is to identify and characterize a fundamental set of abstractions to design a software tool to simulate the behaviour of one or more Air Traffic Control (ATC) Primary Surveillance Radar (PSR) and Secondary Surveillance Radar (SSR) systems. The Air Traffic Control (ATC) radar data is very important in the provision of ATC services. Air traffic controllers use radar data to assure the separation of aircraft. Radar data contains information about the altitude of an aircraft. It also may have indications of emergency conditions transmitted by means of a transponder from an aircraft to a radar source on the ground. Simulating the generation of these radar data is important for training ATC operators and testing other ATC equipment that uses radar surveillance data as input. To simulate the generation of radar data, it is required to simulate aircraft, surveillance radar and the environment between aircraft and radar, which may consists of simulation of weather conditions and obstructions. Simulation provides useful means to analyze and study the reaction of ATC radar system against different conditions. In particular, simulation avoids the high cost and often high risk of using real inputs (i.e., flying real aircraft) for the purposes of training and equipment testing We have also demonstrated the practical application of the concepts presented in this dissertation through the implementation of an ATC radar simulation tool.
