Georgia-based aircraft maintenance company Southeast Aerospace (SEA) received a supplemental type certificate to install the Garmin GI 275 electronic flight instrument as an electronic standby instrument in Part 25 aircraft.
The project was a collaboration between SEA, Garmin, and aerospace engineering firm Peregrine to offer transport category aircraft easy-to-install and cost-effective replacements for electronic standby instruments (ESI).
“The GI 275 redefines the capabilities of a standby flight display and will offer operators a modern and cost-effective replacement solution to avoid the high repair costs and ongoing obsolescence associated with legacy standby systems on these aircraft,” said Garmin Vice President of Aviation Sales and Marketing Carl Wolf.
The STC also includes the option for any aircraft on the approved model list (AML) to opt in for “interface of GPS Data, Magnetic Heading, and VHF Navigation information from many common sources approved for interface with the GI 275,” according to an SEA press release. Additional approvals include the option to have the GI 275 equipped with Garmin synthetic vision technology, which can help increase situational awareness.
“The Garmin GI 275 ESI elevates the cockpit. Display clarity, brightness, data presentation, and data accuracy are all leveled up massively with the GI 275 compared to legacy electronic standby instruments,” said SEA Aircraft Modifications Sales Representative Luke Gomoll. “Obsolescence of older ESIs is really a secondary reason to upgrade to the GI 275, and we think that the GI 275 ESI has enough merit on its own to justify upgrades of non-obsolete equipment as well.”
The Part 25 AML ESI STC is available for installation in a variety of business aircraft, including the Hawker 800/1000 Series; Cessna Citation 550, 560, 560XL, and 650; Dassault Falcon 50; Gulfstream G200, GIV, and GV; Challenger 300; and Learjet 60.
