What does RMI do?

What does RMI do?

• A. Points toward 2 VORs and 2 NDBs
• B. Provides attitude information
• C. Displays weather radar
• D. Shows altitude above ground

Answer: (A)

RMI shows the direction to radio navigation aids. It combines bearing information with a heading reference, so you know which way to fly to reach a VOR or an NDB. You can select nav aids to display; many RMIs can show bearings to two nav aids at once—such as two VORs or two NDBs—giving you dual reference points for cross-checking or triangulating your position. The instrument’s pointer indicates the direction to the chosen station relative to your aircraft’s heading, helping you intercept and track courses accurately. This is different from an attitude indicator (which shows sky/ground orientation), weather radar (which displays precipitation), or an altimeter (which shows altitude).
