2A-27-70: Spoiler System:
1. General Description:
The spoiler system for the Gulfstream V assists the flight crew in maintaining roll

aircraft in flight (as speed brakes), and reduce lift and increase braking
effectiveness on the ground (as ground spoilers).
The aircraft has three spoilers on the upper trailing edge of each wing (from

spoiler. The spoilers are manually and electrically operated, hydraulically
powered, and mechanically actuated. They are bonded composite panels hinged
to open forward when extended and close aft when retracted. Four hydraulic
