81194_1.book Page 14 Wednesday, July 25, 2001 12:10 PM 14 ST3000 Wheel Drive Autopilot - Owner’s Handbook Automatic deadband control (Auto Seastate) The wheel pilot is set to AutoSeastate (automatic deadband control) as a default. This causes the pilot to gradually ignore repetitive movements of the boat and respond only to true course variations. By preventing unnecessary rudder movement, AutoSeastate provides the best compromise between power consumption and course keeping accuracy.
81194_1.book Page 15 Wednesday, July 25, 2001 12:10 PM Chapter 2: Using the Wheel Pilot 15 In these situations, the autopilot will not immediately assume the new automatic heading, and will only settle onto course when the automatic trim has been fully established. To minimize this problem, use the following procedure to make major course changes: 1. 2. 3. 4. 5. Note the required new heading. Press STANDBY, disengage the clutch, and steer manually. Bring boat onto the new heading and engage the clutch.

81194_1.book Page 17 Wednesday, July 25, 2001 12:10 PM Chapter 2: Using the Wheel Pilot 17 2.4 Using Track mode In Track mode, the wheel pilot maintains a track between waypoints created on a navigation system. The wheel pilot computes any course changes to keep your boat on track, automatically compensating for tidal streams and leeway.

Cross track error (XTE) 2 Using the Wheel Pilot Cross track error (XTE) is the distance between your current position and the planned route. This is displayed in nautical miles (nm) and is taken directly from your navigator.
81194_1.book Page 21 Wednesday, July 25, 2001 12:10 PM Chapter 2: Using the Wheel Pilot 21 Tidal stream compensation Under most operating conditions, Track mode will hold the selected track to within ±0.05 nm (300 ft) or better. The autopilot takes account of the boat’s speed when computing course changes to ensure optimum performance over a wide range of boat speeds. If speed data is available, the autopilot will use the measured boat speed.

If your navigator transmits valid waypoint name and bearing to waypoint data, you can advance from one waypoint to the next by pressing -10 and +10 together.
81194_1.book Page 23 Wednesday, July 25, 2001 12:10 PM Chapter 2: Using the Wheel Pilot 23 Safety in Track mode WARNING: Track mode provides accurate track keeping even in complex navigational situations. However, it is still the skipper’s responsibility to ensure the safety of their boat at all times through careful navigation and frequent position checks. Passage making in Track mode assists precise navigation and removes the tasks of compensating for wind and tidal drift.
