Which component is a primary function of the Electronic Standby Instrument System?

• A. Flight Data Recorder
• B. Navigation System
• C. Emergency Power System
• D. Attitude Indication

Answer: (D)

The primary function of the Electronic Standby Instrument System (ESIS) is to provide critical attitude indication during flight operations. The ESIS is designed to serve as a backup system for the primary flight instruments, particularly in situations where the primary instruments may fail or are not available. Attitude indication is essential for pilot situational awareness and maintaining control of the aircraft, particularly in instrument flight conditions. The importance of attitude indication can't be overstated, as it allows the pilot to determine the aircraft's orientation with respect to the horizontal plane, aiding in tasks such as leveling the wings or maintaining a climb or descent. In scenarios of instrument flight, where visual references may be minimal or absent, having a reliable source of attitude information is vital for safe aviation operations. While the other components mentioned, such as the Flight Data Recorder, Navigation System, and Emergency Power System, are also crucial for various safety and operational aspects of the aircraft, they do not specifically fulfill the primary role of providing attitude information, which is the essential function of the Electronic Standby Instrument System.
