In short, the G-III is a reliable, long-range private jet that still offers a very large cabin and the high performance standards needed to compete in today’s private jet market.  The Gulfstream series keeps getting better with time, as the G-III demonstrates.

Cabin

The GIII’s cabin is typically divided into three sections so that travelers may enjoy fully reclining club seating, take a nap on the divan, have a meal in the dining area, or participate in a conference at their whim. Seating in the stand-up cabin may be rearranged to hold as many as 18 passengers. The GIII also offers a DVD entertainment system, a large, fully-equipped galley, and a full-width lavatory, which may even include a shower in some aircraft. A total of 169 cubic feet of available baggage area is accessible during flight.

Flight deck

A completely new nose design resulted in a redesigned cockpit as well.  It is three feet longer, providing enough space for a third pilot to come along for extended trips (as much as eight hours).

In addition to the much roomier cockpit, pilots should appreciate the new avionics system.  A Dual Sperry ED-800 electronic flight instrumentation system coupled with a Sperry Primus 800 multifunctional display and a four-screen EFIS dominate the flight deck.  Standard equipment includes three Honeywell laser gyros (which are lighter and more reliable than mechanical gyros), a Sperry SPZ800 flight director system, Global GNS 1000 FMS, a Sperry Primus 800 color weather radar, as well as all necessary communication and situation awareness equipment.

Engines

The choice to use two Rolls-Royce Spey Mark 511-8 engines, the exact engines used on the GII, was not a choice by default. Each engine is able to produce 11,400 pounds of thrust each on takeoff, but the two are flat-rated to 9,000 pounds in order to meet FAR part 36 noise requirements. Before deciding on the two-engine configuration, Gulfstream Aerospace Corp tested three and four-engine configurations.  In the end, they decided that two engines would provide the performance capabilities for the jet while keeping costs low.
