Triplex FMS makes first flight on GV-SP
The first fully synchronized triplex FMS for business aviation made its maiden flight on the prototype Gulfstream V-SP late last month, said Honeywell. According to the avionics maker, the triplex FMS provides increased reliability and safety and reduces pilot workload. The system is part of the GV-SP PlaneView cockpit, featuring Honeywell’s Primus Epic integrated avionics. The triplex designation means that three multifunction control display units in the PlaneView cockpit provide the crew interface to three separate but synchronized navigation/performance computers. Flight data entered into any of the three displays is shared among all three computers.
