Brazil: Brazil is planning to use geospatial technology to improve air traffic management and airspace usage as a part of it Green Skies of Brazil programme. The programme will benefit 10 airports in the Southeast Brazil.
Green Skies of Brazil is a result of a two-year research programme where Brazilian air navigation provider DECEA and Brazilian airlines used flight data analytics to identify methods for improving airspace usage. GE Aviation, a subsidiary of General Electronics and a leading aircraft engine supplier, used flight analytics to evaluate the efficiency of historical flight operations, identify areas for improvement, and quantify the potential efficiency gains.
The company has developed a GPS-based tracking system called Required Navigation Performance (RNP) which uses satellite data to track aircrafts with an accuracy of 32 feet. An RNP-equipped aircraft saves approximately 7.5 minutes per flight which translates into low fuel consumption. In Queensland, New Zealand, the use of RNP has reduced flight delays from 2,400 minutes to 200 minutes per month. In Cusco, Peru, it reduced flight cancellations by a whopping 60%.
Now, DECEA plans to implement this technology at 10 airports in Southeast Brazil. According to an estimate, the new system could potentially save an average of 22 track miles, 7.5 minutes, 77 gallons of fuel, and avoid 1,628 lbs of carbon dioxide per approach compared to the conventional landing techniques. This means that an RNP equipped aircraft could save more than $24 million in operational savings over five years.
