The azimuth card is most accurately described as which of the following?

• A. Heading indicator
• B. Station indicator
• C. Omni Bearing Selector
• D. Course deviation indicator

Answer: (A)

The azimuth card is the rotating compass-like dial inside the heading indicator that shows your aircraft’s heading relative to magnetic north. The gyro keeps the instrument steady while the card rotates to reflect changes in heading, so you read the current heading off the fixed index line on the instrument. This is distinct from navigation aids: a station indicator relates to a VOR station, an Omni Bearing Selector is used to choose a VOR/LOC bearing, and a course deviation indicator shows how far you are off a selected VOR/LOC course. The azimuth card’s purpose is simply to display heading.
