Piggott hook
The Piggott hook is a control element named after Derek Piggott (a kind of "trigger safety") in the cockpit of a glider . The Piggott hook is intended to prevent accidental release or extension of the airbrakes in connection with released brakes during take-off and thus serves the safety of the pilot. Aviation accidents should be avoided which can be traced back to the take-off with accidentally extended spoilers, which cause too low rates of climb. Piggott communicated his idea of such a safety mechanism to a German colleague and employee of DG Flugzeugbau at the SSA Convention in Albuquerque in 2000 . All gliders of the Glaser-Dirks DG-800 / DG-808 and DG Flugzeugbau DG-1000 series that are delivered at the end of 2000 and afterwards will (according to the manufacturer's website) have a Piggott hook and a coupled wheel brake.
