Sydney Airport Activates Precision Approach GBAS System

Há alguns meses, conversava sobre WAAS / SBAS / GBAS com alguns amigos. Eu havia entendido que ainda não tínhamos um planejamento para GBAS no Brasil por conta de limitações técnicas no uso da constelação GPS no hemisfério sul. Mas com essa iniciativa da Austrália, não parece ser o caso.

 

Para a operação de aeronaves que usam VNAV exclusivamente por GPS (como o Phenom e demais usuários de G1000), seria excepcional. Isso sem falar na vantagem de se trocar instalações de novos ILS por procedimentos GNSS com guiagem vertical.

Sydney Airport has placed into operation a ground-based augmentation system (GBAS) supporting satellite-based precision approaches and landings. The airport is the first in Australia to offer a GBAS landing system, Airservices Australia said.

 

The Honeywell SLS-4000 GBAS, branded as SmartPath, transmits corrected, differentialGPS signals by VHF datalink to an aircrafts flight management system, providing a precision approach path that enables it to land within one meter of the runway center line in low visibility conditions. The Sydney GBAS installation is capable of providing up to 26 simultaneous instrument approaches within a 26-mile radius of the airport. Airservices said that it is working with airlines to encourage fitment of SmartPath-capable avionics.

 

The government-owned air navigation services provider started operational tests of theGBAS system in December 2012 in conjunction with Qantas, using Boeing 737-800 and Airbus A380 airliners operated by pilots qualified to fly SmartPath approaches. Qantas flew some 750 GBAS approaches as part of that evaluation; during an earlier trial of a prototype system between 2006 and 2010 the airline flew more than 2000 satellite-guided precision approaches.

 

Were proud to be the first airport in Australia to install and use this technology, said Kerrie Mather, Sydney Airport CEO. This revolutionary technology does the work of six separate instrument landing system units. Its an additional layer of safety that more and more airlines will take advantage of as new aircraft models such as the Airbus A380 and Boeing 787 Dreamliner go into service.
