20 May 2019:Gulfstream Aerospace has set another city-pair speed record on sustainable alternative jet fuel (SAJF). The record was achieved by the Gulfstream G550, connected Charleston, South Carolina, with Farnborough, England, a distance of 3,591 nautical miles/6,651 kilometers, at an average speed of Mach 0.85 in 7 hours and 13 minutes.
"Our record-breaking flight on the G550 is another example of our aircraft's continued high performance with SAJF," said Mark Burns, President of Gulfstream. "We first used SAJF in June 2011 to cross the Atlantic on a G450 and have used it since 2016 with our corporate, demonstration, Customer Support and flight-test aircraft. This is a fuel that we use in Savannah and the fuel that we recommend - and sell - to our customers in Long Beach, California. It is safe, approved, does not hinder aircraft performance and provides a long-term benefit to the environment.
"As an industry, we must continue to promote SAJF and its benefits and collaborate to find a solution for the infrastructure and economic challenges that impede widespread use of the fuel around the world," added Mark Burns.
SAJF has been approved by the Federal Aviation Administration and deemed safe to use. The Gulfstream has also proven that by flying almost 800,000 nm/1.5 million km and setting five city-pair records on SAJF. SAJF meets the same fuel specification as conventional Jet-A and gives at least the same performance and safety standards. Each gallon of fuel burned attains overs a 50 per cent reduction in C02 emissions, relative to petroleum-based jet fuel, on a lifecycle basis.
