Brazilian operator Gol will equip its Boeing 737 fleet with the Rockwell Collins datalink system and multi mode receiver certified for a GPS landing system as a precursor to developing a Required Navigation Performance (RNP) programme.
A GPS landing system will allow Gol to perform continuous ascents or descents through the plotting of curved segments in a single procedure in advance of Brazilian regulators authorising the carrier to perform RNP operations within the country.
GOL is interested in using RNP once the procedures gain regulatory approval, which is expected by the end of 2010, Gol vice president of technical Fernando Rockert de Magalhaes told ATI in December 2009.
RNP uses GPS and other signals to allow aircraft to operate along a pre-defined flight path with a specific degree of lateral accuracy.
GOL has selected Rockwell Collins' CMU-900 communications management unit and its GLU-925 multi mode receiver (MMR), a navigation sensor that provides highly accurate position data to enable both GPS landing systems and RNP operations.
The GLU-925 MMR is also certified for precision landing using instrument landing systems (ILS) while the CMU-900 enables digital communications between aircraft systems, pilots, airline IT infrastructure and various operations control functions. The CMU-900 also enhances an airline's ability to more effectively communicate and manage airline operations.
GLU-925 MMR and CMU-900 deliveries are scheduled to begin in May, a Rockwell Collins spokeswoman says. .
