According to the Department of Airspace Control (Decea) terminals aviators Guarulhos, Brasilia, Curitiba and Galeão are the most affected by delays due to bad weather.
In normal situations, the Cumbica Airport, in Guarulhos, has an average of 5.3% of delays. In days of weather impact, as fogs, this figure rises to 16.7%.
In Brasilia and Curitiba, the average reaches quadruple. The Airline Gol believes that South airports, like Porto Alegre, Caxias do Sul, Joinville, Navegantes, Curitiba, Londrina and Maringa, are the most affected by the bad weather.
To improve the issue of delays and everyday passengers, the Decea installed a new technology, called D-VOLMET, where the pilot can receive, in seconds, information about the weather to take the best decision in the case the need for change of course or landing at another airport.
The pilot should just enter the code from the airport to receive this data, without the need for verbal contact between pilot and the control tower, which also avoids the problems in communication.
The system can now be deployed in 100% of TAM aircraft and 51% of the Gol aircraft, which intends to expand this new system to its total aircraft operating by 2013.
