A situação da infraestrutura aeroportuária na região norte e seu potencial apoio à aviação regional

The North region of Brazil comprises a wide area with scarcity of transport infrastructure in general. This paper aims to show a quantitative and qualitative analysis of available airport network in the northern Brazilian region. Some current bottlenecks are identified and some actions are proposed. In this region is important that the aviation can play its role of the integration of the scattered communities with the most important regional centers.

Systematics of Deliveries to Increase Postgraduate Courses Scientific Productivity

To assist researchers in the development of scientific studies and optimize the resources invested in engineering postgraduate programs, it is necessary instruments to support both teachers and students in carrying out the activities during the courses. Although there are proposals in the literature for structuring specific studies, there are gaps regarding the follow-up of these activities in a systematic and gradual manner. From an action research in a postgraduate course in engineering, in this study was developed, tested, evaluated and improved a tool to assist students in the development of subject-specific studies in postgraduate courses, identified as Systematics of Deliveries. The results show that the application of this tool can be useful not only in increasing the productivity of postgraduate courses, but also in the personal development of students as they follow the step-by-step the management of scientific studies.

ANALYSIS OF CRITERIA FOR CLOSELY-SPACED PARALLEL RUNWAY APPROACHES: INFLUENCES AND CAPACITY CONSTRAINTS IN A MULTIPLE AIRPORT SYSTEM

In order to increase arrival rates at many of todays heavily congested airports, simultaneous approaches, whenever possible, are conducted on parallel runways. For many years, the FAA has permitted simultaneous independent instrument approach operations only on parallel runways with a minimum separation of 4300 ft. Nowadays, new procedures have been developed to increase the utilization on closely-spaced runways, PRM/SOIA (Precision Runway Monitor/Simultaneous Offset Instrument Approach), one of the most recent of such procedures, allows simultaneous approaches in systems of runways spaced as close as 750 ft. Fraga et al. (2010) [6] using computer simulation showed the potential application of PRM/SOIA at Sao Paulo/Guarulhos International Airport (GRU) evaluating its impact on the airport runway hourly capacity. The present paper considering GRU as part of the airport system of TMA-SP (Sa˜o Paulo Terminal Airspace) focuses on the influence of PRM/SOIA implementation at GRU on the system of main airports in the terminal airspace. Evidences were found that TMA-SP current overlapping approach procedures generate interferences on the operations of the airports in the system reducing the overall runway hourly capacity of the airports. In order to quantify this interference simulation was used to evaluate and to compare the airport system runway hourly capacity as opposed to the individual airport runway hourly capacity added up. It was found that TMA-SP airport system runway hourly capacity is about 30% less than the estimated overall runway hourly capacity of the airports alone.
