Aviation Navigation: Synchronizing the RMI and HSI

How can you synchronize the copilot's RMI heading with the copilot's HSI heading?

a) By adjusting the RMI knob

b) By syncing it with the pilot's HSI

c) By contacting air traffic control

d) By pressing the heading sync button

Final answer:

The correct answer is option D.

The copilot's RMI (Radio Magnetic Indicator) heading is changed to match the copilot's HSI (Horizontal Situation Indicator) heading by utilizing the 'Heading Sync' button. This process is not performed by adjusting the RMI knob, syncing with the pilot's HSI, or contacting Air Traffic Control. The 'heading sync' button is generally found on the HSI unit. Once this button is pressed, the RMI heading should reflect the HSI heading. In some older systems the RMI may have a knob that needs to be manually adjusted to match the HSI, but in most modern systems, it's achieved through the 'heading sync' command.

To change the copilot's RMI heading to match the copilot's HSI heading, you need to:

1. Use the RMI knob to adjust the heading on the copilot's RMI display.

2. Sync the copilot's RMI with the pilot's HSI by aligning the heading bug on both instruments.

Pressing the heading sync button or contacting air traffic control does not directly change the copilot's RMI heading to match the copilot's HSI heading.
