Image Number 2 for United States Patent #4591113.

On an aircraft having spoilers on the wing, the spoilers are converted, according to this invention, following the ACT philosophy, for use in countering gust effects. Accordingly, a sensor of gusts is arranged to transmit warning of the arrival of a significant gust to a spoiler operator which, taking into account airspeed, deploys the spoilers in a mode so that a phase of spoiler generated lift decrement is timed to coincide with effective arrival of the gust.
