More Versatility Accolades For G280 In 2020 Earlier in the year the Gulfstream G280 demonstrated once again it is one of the best super-midsize luxury jets on the market. Looking back to February 16, the record-making G280 left Vermont’s Burlington International Airport bound for London City Airport arriving 6 hours and 10 minutes later. Of course arrival into London City Airport requires a steep-approach landing. The 2,735-nautical mile/5,065-kilometer trans-Atlantic journey was completed at an average speed of Mach 0.83. Aircraft that operate at London City require steep-approach certification because of the airport’s short runway and stringent noise-abatement requirements.
