The Airspace Control Department (DECEA) began last Wednesday (04/10), at 21pm, the implementation of the Route Efficiency Project, whose scope includes the restructuring of the entire fixed route network in the Information Information regions. Flight from Brasília and Recife (FIR-BS and FIR-RE).
The Project, which is coordinated by the Institute of Aeronautical Cartography (ICA), is part of DECEA's SIRIUS Brasil Program, and aims to reduce distances flown through the optimization of flight paths and rational segregation of airspace depending on demand projected for the next ten years.
Collaborative Decision Making
The Route Efficiency Project was developed through t work between various bodies and sectors of the Brazilian Airspace Control System (SISCEAB). In the planning phase, there was more active work with the Four Integrated Air Defense and Air Traffic Control Centers (CINDACTA I, II, III and IV). In the validation phase, the Air Navigation Management Center (CGNA) and airlines participated more actively, at which time tools and software for modeling and validation of scenarios, with the objective of measuring the reduction in fuel consumption and CO emissions2 In the atmosphere.
Approximately 500 air traffic controllers of CINDACTA I and III They were trained through theoretical and practical instructions on simulators for route changes. During the training, suggestions for improvements to the new air circulation were collected, which will be analyzed and implemented, if appropriate, in the post-implementation phase.
As a result of this multidisciplinary effort, 127 airways were modified in the Brasília and Recife FIR and 213 air navigation procedures for arrival (STAR) and departure (SID) charts in eight Terminal Control Areas (TMA), which made the air network well more efficient.
According to the Deputy Manager of the Route Efficiency Project, Captain Specialist in Air Traffic Control Bruno da Silveira Topini, the results of the simulations carried out show that the new sectorization increased the control capacity in the modified airspace. “It provides better demand management, in order to reduce and, in most cases, avoid waiting to enter more congested air spaces, as is the case with TMA-SP”, states the Official.
In simulated results, considering the pre-pandemic air network, there was a reduction of approximately 73.000 nautical miles flown in one year of operation, resulting in an approximate reduction in the burning of approximately 440 tons of aviation kerosene and emissions of 1.340 tons of carbon dioxide. In the atmosphere. “These data were used as performance indicators, considering the planned scenario, in comparison with the trajectories currently flown”, explains the Efficiency Project Manager, Lieutenant Colonel Specialist in Air Traffic Control Clóvis Fernandes Junior.
More specific information can be found in the Aeronautical Information Circular that discloses in technical detail the Route Efficiency Project (AIC 25/23). s can send questions or suggestions via DECEA channels to serve its s, which will be considered during adjustments and carried out during the project's post-implementation work.
The work of the SIRIUS Brasil Program is continuous and incessant, always seeking to comply with the commitments of the International Civil Aviation Organization (ICAO), to promote the aeronautical industry, thus maintaining a cycle of continuous improvement in global air navigation.
