The GPSS interfaces with the composite roll steering commands output by GPS navigators to fly a complete, pre-programmed flight plan—hands off. If the GPS database includes instrument approach procedures, the flight plan can also include an approach to the destination airport. GPSS is available as a standard feature on the System Fifty-Five X autopilot, and is also available as an upgrade to any existing S-TEC autopilot.*

GPSS benefits:

• Complete GPS Flight Tracking: Interfaces with GPS to fly pre-programmed flight plans hands-free.
• Smooth Waypoint Transitions: Calculates turn initiation point to fly from centerline of current leg to centerline of new leg, enabling autopilot to fly a precisely-curved transition path between legs.
• Reduced Pilot Workload: Eliminates need to set course arrow or heading bug at leg changes.
• Enhanced Autopilot Functionality: Fully-interoperable with any existing S-TEC model autopilot.*
