Which device provides a visual representation of VOR signals without needing interpretation?

The Horizontal Situational Indicator (HSI) is designed to provide pilots with a clear and straightforward visual representation of VOR (VHF Omni-directional Range) signals. It integrates various information into a single display, showing the aircraft's position relative to the navigation aid, as well as the desired course or track. The HSI typically features a rotating compass card and a course selector, which simplifies navigation by allowing pilots to observe their heading, course, and deviation from the intended flight path simultaneously.

In contrast, devices like the Heading Indicator, Radio Magnetic Indicator, and Automatic Direction Finder may require more interpretation and understanding of the displayed information to assess navigation situations effectively. The HSI's intuitive layout minimizes the need for complex deductions, rendering it a valuable tool for ensuring situational awareness during navigation, particularly when flying with VOR signals. This efficiency is crucial in maintaining safety and precision during flight operations.
