Plain English Meaning

Sounds the airplane makes to tell the pilot something needs attention. These can be spoken words like "Traffic, traffic," or simple tones, beeps, or horns.

Full Definition

Audible alerts produced by an aircraft's avionics or warning systems to notify the pilot of a specific condition requiring attention, such as traffic conflicts, terrain proximity, stall onset, altitude deviations, or system faults. Aural warnings may take the form of synthesized voice messages (for example, "Traffic, traffic" or "Pull up"), tones, horns, or beeps, each tied to a defined alert condition.

Context Anchor

In traffic avoidance, aural warnings may come from equipment that detects nearby aircraft and gives the pilot an audible traffic alert.
