What does EFIS stand for?

• A. Electronic Flight Instrument System
• B. Electronic Flight Information System
• C. Enhanced Flight Instrument System
• D. Electronic Flight Instrument Service

Answer: (A)

EFIS stands for Electronic Flight Instrument System. The key idea is that this is the cockpit system that electronically presents the flight instruments on digital displays, replacing the traditional analog gauges. The “Instrument” part signals that it’s the instrument data—attitude, airspeed, altitude, vertical speed, and flight/navigation information—being shown, rather than a generic data set or a service. The other options use terms that aren’t the standard name for this cockpit technology, such as Information, Service, or Enhanced, so they don’t match the well-established terminology used in glass cockpit systems.
