Garmin has been granted a supplemental type certificate (STC) by the FAA, which allows the retrofit of the company’s GI 275 electronic flight instrument (EFI) in Bell 407s and Robinson R66 helicopters.
The GI 275 provides a scalable approach to an avionics upgrade that is a direct replacement for a variety of legacy primary and backup flight instruments, including the primary attitude indicator, course deviation indicator (CDI), horizontal situation indicator (HSI), or the multi-function display (MFD).
The GI 275 is designed to take advantage of the common 3.125-inch flight instrument size, reducing installation time and preserving the existing instrument panel. The GI 275 is available as a retrofit through authorised Garmin dealers.
