  • Page 34: Chapter 3: Advanced Operation

    3.1 Operating in Track Mode Track mode is used to maintain a track between two waypoints created on a GPS, Decca, or Loran navigation system. The autopilot will then compute any course changes to keep your boat on track, automatically compensating for tidal streams and leeway.

  • Page 35: Automatic Acquisition

    Automatic Acquisition Automatic acquisition can only be achieved if the pilot is receiving cross track error and bearing to waypoint information (via SeaTalk or NMEA 0183). It is initiated as follows: 1. Bring the vessel to within 0.1 nm of track. 2.

  • Page 36: Manual Acquisition

    Chapter 3: Advanced Operation The display shows the new bearing to waypoint. Manual Acquisition For manual track acquisition, when only cross track error data is available: 1. Steer the vessel to within 0.1 nm of track. 2. Bring the heading to within 5° of the bearing to the next waypoint. 3.

  • Page 37: Cross Track Error

    • Make positive positional checks at regular intervals, especially if navigational hazards are close by. Cross Track Error Cross track error (XTE) is the distance between the current position and a planned route. This is displayed in nautical miles (nm), statute miles (SM) or kilometres, and is taken directly from your navigator.

  • Page 38: Tidal Stream Compensation

    Chapter 3: Advanced Operation Tidal Stream Compensation Under most conditions, Track mode will hold the selected track to within ±0.05 nm (300 ft) or better. The autopilot takes account of vessel speed when computing course changes to ensure optimum performance over a wide range of vessel speeds. If speed data is available, the ST7000 Plus uses the measured vessel speed.

  • Page 39: Skipping A Waypoint

    ST7000 Plus Autopilot Control Unit Owner’s Handbook To accept the new target waypoint, press track. Skipping a Waypoint – SeaTalk Navigators Only If you wish to advance to the next waypoint before you have arrived at the target waypoint, press track for 1 second. The Waypoint information for the next waypoint is displayed.

    Chapter 3: Advanced Operation change in the opposite direction. Note: Provided the vessel remains within 0.1 nm of track, there is no need to steer back towards the track. Safety Passage making in Track mode removes the chores of compensating for wind and tidal drift, and will aid precise navigation.

  • Page 41: Operating In Wind Mode (Windtrim)

    3.2 Operating in Wind Mode (WindTrim) Wind mode (also known as WindTrim) allows the ST7000 Plus to maintain a course relative to an apparent wind angle. It uses wind trim to eliminate the effects of turbulence and short term wind variations, and provides smooth precise performance under Wind mode operation with minimal power consumption.

  • Page 42: Adjusting The Locked Wind Angle

    Chapter 3: Advanced Operation Adjusting the Locked Wind Angle The locked wind angle can be adjusted by changing course using the -1, +1, -10 and +10 keys. For example, to bear away by 10° when the vessel is on starboard tack, press -10 to turn the vessel 10°...

  • Page 43: Dodges

    If you do not accept the previous wind within this time, the autopilot locks on to the current apparent wind angle. Dodges Full control is still available from the keypad when the autopilot is in Wind mode. • Dodge manoeuvres are accomplished by simply selecting the desired course change using the course change keys (-1, +1, -10 and +10).

  • Page 44: Operating Hints

    Chapter 3: Advanced Operation Operating Hints • Major changes to the selected apparent wind angle should be made by returning to Standby mode, changing course manually, then reselecting Wind Mode. • Wind mode filters the windvane output. This provides the optimum response for off-shore conditions where genuine shifts in wind direction occur gradually.

  • Page 45: Adjusting Autopilot Performance

    3.3 Adjusting Autopilot Performance The response level and rudder gain can be adjusted during normal operation using the resp key. The calibration settings for response and rudder gain (see Dealer Setup in Chapter 4) are restored when the system is powered on. Changing the Response Level The response level controls the relationship between the autopilot’s course keeping accuracy and the amount of helm/drive activity.

  • Page 46: Changing The Rudder Gain

    Chapter 3: Advanced Operation 3. Wait for 10 seconds, or press disp, to return to the previous display. Changing the Rudder Gain Press either the resp key for 1 second or the +1 and -1 keys together for 1 second to display the Rudder Gain screen, and adjust the setting in the same way as for the response level.

  • Page 47: Off Course

    Off Course OFF alternating with COURSE This alarm is activated when the vessel has been off course from the locked heading by more than the specified angle for more than 20 seconds (see Using Auto Mode in Chapter 2). The alarm is cleared if the heading recovers or the course is changed, or if the operating mode is changed.

  • Page 48: Waypoint Advance

    Chapter 3: Advanced Operation • Track mode is engaged and the position transducer (GPS, Loran, Decca) is receiving a low strength signal – this will clear as soon as the signal strength improves. • Wind mode is engaged and the autopilot has not received wind angle data for 30 seconds.
