G650 Cockpit
Gulfstream Fly-By-Wire
The digital fly-by-wire system is based on that in the G650,with a pair of dual-channel Thales flight-control computers
and Parker electronic power-control actuators. But new to
the G500 and G600are the active-inceptor sidestick controls.

These are electrically back-driven, so they appear to be mechanically
linked side to side: When one sidestick is movedthe other moves with it. The sidesticks also move in response
to autopilot inputs, providing the pilots with tactile and visual
feedback.
" Gulfstream further pushes the technology envelope by equipping the G650 with a computer-controlled, highly redundant fly-by-wire flight
system, which, working in concert with the pilot or on full automatic, provides measured, minute adjustments that create smoother flights and increase passenger comfort."

The G500 is also the first business aircraft manufactured with a Data Concentration Network. DCN fiber-optic wires line the airframe, significantly reducing cables and relay equipment.
In addition to the active sidesticks, the new Symmetry flight
deck for the aircraft introduces touchscreen displays and other
features that distinguish it from the PlaneView cockpits of current-
production Gulfstreams. Based on Honeywell integrated
avionics, Symmetry provides four large-format, landscape-orientation
flight displays, their associated cursor-control devices
relocated from the sidewall armrests to the center console to
make room for the sidestick controls.
Three large, software-driven touchscreens on the overhead
panel control virtually all airframe systems. Four smaller
touchscreens, two outside the main displays and two in the
center console, provide flight management system, radio and
avionics/display controls. There are no conventional multifunction
control display units. Wider-screen standby flight
instruments are installed in the glareshield. All this provides
unprecedented redundancy.
" A next-generation Enhanced Vision System heightens pilot awareness in low visibility. An improved infrared sensor boosts resolution by 400 percent, and camera advancements provide a wider field of view. The EVS is linked to a head-up display, allowing the pilot to view images on a transparent screen positioned in his or her field of vision. Gulfstream is the first business aviation company to offer this third-generation EVS, and it comes as standard equipment on the G500."
The new aircraft are equipped with a standard head-up
display and third-generation Elbit Kollsman EVS III infrared
enhanced-vision system camera with four times the image
resolution, an integrated exterior window and digital interface
to the avionics suite.
Several systems are carried over from the G650. The electric
system has left and right engine-driven 40-kVA generators,
a 40-kVA generator driven by the auxiliary power unit
and a 15-kVA ram air turbine. The dual 3,000-psi hydraulic
systems, are powered by left and right engine-driven pumps, plus a left-side
electrically powered auxiliary pump and left-to-right power
transfer system. There is no need for a hydraulically powered
motor generator.
Also shared with the G650 are the digital air data computers,
secondary power distribution system, satellite communications
and cabin management system .
The oxygen, cabin pressurization, landing-gear control and
aircraft health and trend monitoring systems are adapted
from the G650, but are more fully integrated with the avionics
system.
