What would the tail of the RMI indicate when an aircraft is flying outbound on a magnetic bearing?

When an aircraft is flying outbound on a magnetic bearing, the tail of the Radio Magnetic Indicator (RMI) shows the magnetic bearing from the station. The RMI is designed to provide pilots with information about their position relative to a VOR (VHF Omnidirectional Range) or NDB (Non-Directional Beacon) station.

In this situation, if the aircraft is flying away from the station, the tail of the RMI points in the direction from which the aircraft is departing. This is crucial for navigation, as it allows the pilot to understand the path being followed away from the navigation source. Understanding the RMI's indication aids in maintaining situational awareness and ensuring accurate course tracking during the outbound leg of the flight.

The other options do not apply here because the magnetic heading indicates the direction the aircraft is facing, the bearing to the station shows the direction toward the VOR or NDB when flying toward it, and relative wind direction pertains to the wind flow outside the aircraft, not to navigation information. Therefore, option C is the clear and accurate choice in this scenario.
