Garmin has announced Supplemental Type Certification (STC) by the FAA for the GI 275 electronic flight instrument in Bell 407 and Robinson R66 helicopters. The GI 275 is a scalable, cost-conscious approach to an avionics upgrade that is a direct replacement for a variety of legacy primary flight instruments in the cockpit, including the primary attitude indicator, course deviation indicator (CDI), horizontal situation indicator (HSI), or the multi-function display (MFD).
