Which information is not provided by the EHSI?

• A. Bearing 1 and 2
• B. Groundspeed
• C. Heading
• D. Attitude

Answer: (D)

The EHSI is a navigation-oriented display that combines information essential for flying on a horizontal plane. It shows where you’re pointed relative to magnetic heading and it also provides bearings to selected navigation aids. In practice, you can see bearing information to navigation aids (often two: nav 1 and nav 2) and you can read your current heading on the instrument’s rotating compass card. It does not show the aircraft’s attitude or orientation relative to the horizon—this is the role of the Attitude Indicator (artificial horizon). So, the information not provided by the EHSI is Attitude, since attitude describes pitch and roll relative to the horizon, which the Attitude Indicator displays.
