DO YOU NEED EFIS?

摘要

Most instrument pilots flying today probably learned with conventional six-pack flight instrumentation. But, that's changing. Rare is a new aircraft available without EFIS and popular shops are installing glass retrofits nearly as fast as they're installing ADS-B systems. Do you need EFIS? Should you consider upgrading your six-pack panel to a fancy electronic package? Like so much in life, the discriminating answer to that question is, "It depends." Let's look at some pros and cons. EFIS is more reliable. With essentially no moving parts, there's almost nothing that can wear out. Yes, EFIS failures do happen, sometimes spectacularly, but those failures are less common and usually more immediately noticeable than with spinning-mass gyro instruments.
