Thales computers for Gulfstream G650 FBW

Thales is to provide quadruple-redundant computers for the Gulfstream G650’s fly-by-wire (FBW) flight controls. The new large-cabin, ultra-long-range business jet will be the first to feature Thales’ Quad-Dual architecture. While Thales will act as Gulfstream’s deputy, the aircraft manufacturer retains authority for FBW system integration.

According to Alain Boursier, general manager of Thales’ aerospace business in Canada, in 2004 Gulfstream selected the company for its advanced flight control research program, which eventually yielded the G650’s flight control configuration. It consists of two primary computers and a backup unit. The primary computers share work–unless one of them is totally out of action. In that case, the primary system reconfigures itself to a downgraded safe mode of operation.
