When tracking a bearing from an NDB, which RMI indicates that you are on course?

When tracking a bearing from a Non-Directional Beacon (NDB), the Radio Magnetic Indicator (RMI) displays the bearing to the NDB relative to the aircraft's heading. The RMI pointer, which indicates the direction to the NDB, is positioned such that when you are on course, the pointer will point directly ahead, aligned with the aircraft's heading.

In this scenario, if you are tracking correctly along a bearing to the NDB and the RMI needle is aligned with the aircraft's heading, it shows that you are on the correct course. This alignment ensures you are maintaining the intended track to the NDB.

Understanding how the RMI functions is crucial for navigation as it provides real-time feedback on your position relative to the NDB, enabling you to make necessary adjustments to maintain your path accurately. Knowing which specific RMI indicates your course helps clarify the operational role of each indicator in your navigation strategy.
