The GIV-SP is a large cabin, long range airplane that seats up to 19 passengers in three discreet living areas. Like the GIV it employs a Goodyear Aerospace brake-by-wire system and a Dowty fail-passive steer-by-wire system, making pilot maneuverability easier. The Rolls-Royce Tay engines, bring significant fuel burn and noise emission improvements despite their higher thrust output than the GII and GIII Spey engines.
