rolloff (usually uncountable, plural rolloffs)

   • 1982, National Transportation Safety Board, “1.16.2 Aircraft Characteristics”, in Aircraft Accident Report: Sky Train Air, Inc., Gates Learjet 24, N44CJ, Felt, Oklahoma, October 1, 1981‎, archived from the original on 21 February 2021, pages 11–12:

     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.

2. A rolloff dumpster.
