Which one of these is not shown on the EADI?

• A. HDG
• B. Attitude indicator
• C. Bank angle
• D. Turn rate

Answer: (A)

An Electronic Attitude Direction Indicator focuses on how the aircraft sits relative to the horizon. It shows the artificial horizon, the aircraft symbol, the bank angle (via the horizon tilt), and a turn-rate cue to indicate how quickly you’re turning. Heading, or the direction you’re pointing relative to north, isn’t part of this attitude-focused display. That navigation information is provided by the EHSI/HSI or other heading indicators elsewhere on the panel. So heading isn’t shown on the EADI, which is why that option is the best choice. The other items—attitude indicator, bank angle, and turn rate—are all depicted on the EADI.
