Gulfstream G550

The Gulfstream G550 is a business jet aircraft produced by General Dynamics' Gulfstream Aerospace unit in Savannah, Georgia, US. The certification designation is GV-SP. As of January 2016, there were 450 G550s in service. The final G550 commercially available unit is to be delivered in 2021. A version of the airplane with reduced fuel capacity was marketed as the G500.
Development.
The G550 (GV-SP) with improved engines received its FAA type certificate on August 14, 2003. In 2014, Gulfstream looked at a re-engine with the Rolls-Royce Pearl BR700 development announced in May 2018 for the new Global Express 5500 and 6500 variants but preferred the BR725-powered, 7,500 nmi G650. The 500th Gulfstream G550 aircraft was delivered in May 2015.
As it is replaced by the $54.5 million Gulfstream G600 with a lower 6,200 nmi range but with a better cabin and cockpit, faster long range cruise and lower fuel burn, it could leave production in 2019. Deliveries went from 50 aircraft in 2011 to 19 in 2016 and with 40 units for sale in a fleet of 540, its valuation are falling: a 10-year-old G550 valued $28 million a year before is worth $18-$20 million in January 2017, while a two-year-old went from $40 to $35 million. In May 2017, early 2003 G550s are valued $14 million against more than $45 million new, flying an average of 425 h per year. In December 2018, a 2012-2013 G550 is valued $28-31 million, and it costs $7,135 per hour for 400 hours a year.
As it was replaced by the Gulfstream G600 by October 2019, the G550 was kept in limited production for long-term special missions applications and government orders.
Design.
Compared to the Gulfstream V, drag reduction details boost range by and increase fuel efficiency. Maximum takeoff weight (MTOW) is increased by and takeoff performance is enhanced. A seventh pair of windows is added and the entry door is moved forward to increase usable cabin length. The PlaneView flight deck features cursor control devices, Honeywell Primus Epic avionics, standard head-up guidance system by Rockwell Collins and enhanced vision system by Elbit, improving situational awareness in reduced visibility conditions.
Initial long-range cruise altitude is FL 400-410, first hour fuel burn is decreasing for the second hour to for the last hour. Flight hourly budget is $700-950 for engine reserves, $250 for parts and 2.5 maintenance hours. It competes against the Bombardier Global 6000, which has higher direct operating costs and less range but a more spacious cross section, and the Dassault Falcon 7X with fly-by-wire flight controls, better fuel efficiency and a wider but shorter cabin.
Operators.
Civil operators.
The aircraft is operated by private individuals, companies and executive charter operators. A number of companies also use the aircraft as part of fractional ownership programs.
