(aviation) A sudden large uncommanded roll to the left or right experienced by an aircraft entering a stall, resulting from one wing stalling slightly before the other and exacerbated by the reduction in aileron control authority at high angles of attack.

The Learjet does not possess sufficient inherent prestall buffet characteristics at low speeds to provide the pilot with a clear warning that the aircraft is stalled before it enters a flight condition from which a normal recovery cannot be accomplished. Therefore, the aircraft is equipped with an artificial stall warning system which incorporates a stickshaker and stickpusher to provide a prestall warning in order to prevent an abrupt wing rolloff. The system includes a stall vane on each side of the nose of the aircraft, two angle of attack indicators, two stall warning lights, and a computer.
