Although the business jet manufacturer remained quiet for most of 2021, Gulfstream Aerospace has rolled out multiple new aircraft concepts and upgrades in October. The Gulfstream G280, a super-midsize aircraft, will see new features and cabin options. There are more than 220 G280 aircraft currently in service, making it a popular choice for operators."We are seeing tremendous demand for the G280, further proving the aircraft is the high-performing super-midsize leader," said Mark Burns, president, Gulfstream.The G280 will now have the option to be equipped with a plasma ionization clean air system. While the aircraft already has a 100%-fresh-air environment, this system has proven lab tests to neutralize pathogens and allergens.As for the avionics, operators who choose avionics upgrade V3.6.1, including SiriusXM graphical weather with real-time updates; electronic charts to create a paperless flight deck; surface management system to alert pilots to unsafe ground and arrival operations, preventing runway incursions; as well as access to vertical weather and predictive windshear information.In an attempt to reduce downtime, the G280 will have increased vertical separation minimum validation intervals from 24 to 96 months. The Controller-Pilot Datalink Communication (CPDLC) is also now FANS-E compliant.
