visual-aural range
visual-aural range[′vizh·ə·wəl ′ȯr·əl ′rānj] (navigation) A very-high-frequency radio range that provides one course for display to the pilot on a zero-center left-right indicator and another course, at right angles to the first, in the form of aural A-N radio range signals; the A-N aural signals provide a means for differentiating between the two directions of the visual course.
