“Bank angle” is an aviation warning that alerts pilots when an aircraft’s roll angle becomes excessive near the ground or in another potentially hazardous situation. Short recordings of the repeated alert circulate online because the phrase is instantly understandable and has a distinctive automated delivery. Editors often separate it from cockpit footage and apply it to flight simulations, vehicle videos, and visual jokes involving anything that leans sharply. It remains useful because it communicates instability and possible danger within only a few seconds.
