Plain English Meaning

A warning the pilot hears, rather than sees. The airplane makes a sound — a horn, beep, or spoken message — to get the pilot's attention when something needs to be checked or corrected.

Full Definition

A sound-based alert generated by an aircraft system to notify the pilot of a specific condition requiring attention, such as an approaching stall, gear not extended, or autopilot disconnect. Aural warnings are produced by horns, tones, voice messages, or buzzers, and are typically triggered automatically when sensed parameters cross a defined threshold.
