2.2 Basic Operating Principles and Hints
Auto and Standby
Autopilotoperationhas beensimplifiedto asetof push-buttonkeys,
allofwhich are confirmedbya beep orbeeps.
Engagingtheautopilot couldnotbe easier.Simplysteer yourvessel
ontotherequired heading, presstheAUTObuttonand release the
wheel/tiller. Whenyouwant toreturn tomanualsteeringsimply
pressSTANDBYand regaincontrol.
Caution: Hand steering is not possible when your vessel is under
autopilot control. The pilot MUST be disengaged by pressing
STANDBY.It is the skippers responsibility to ensure that all crew
members are aware of this procedure.
CourseChanges
Coursechangesunder autopilotcontrol are madeusing the–1, +1,
–10and+10 keys. Thesekeysallow youtomake changesin 1°or
10°incrementsto port (–)and starboard (+).
Track
Trackmodetells theautopilot to steerunder thesupervisionof a
radioor satellitenavigationsystem. Therefore,the followingbasic
guidelinesshouldbeobserved before track isengaged:
• Alwayssteeryour vesselto within0.1nmof thetrack.
• Makesurethat thereare nonavigationalhazards eitherside ofthe
intended track.
• Maintainanaccurate log.
• Make regular plots to verify the computed position provided by your
positiontransducer.
• Maintaina properlookoutat alltimes.

TrackAdvance/Acceptance
Ifyournavigation receiver istransmittingwaypoint number and
bearingtowaypoint, a waypointalarmwill sound wheneveranew
targetwaypoint isselected.Theautopilot maintainsthe current
headingandautomatic track controlissuspended. Check thenew
bearingtowaypoint, makesure that itis safetoturn, andthenreturn
toautomatictrack controlby simply pressingthetrackkey. Thenew
targetwaypointis acceptedand the autopilotsteers yourvesselonto
the new heading.
Youmayfind thatthetidal offsetisvery differentonthe newbearing.
Therefore,it isadvisableto checkthe crosstrackerror(XTE)after a
coupleofminutes. Ifthe cross trackerror increases,makea course
adjustment(e.g.,10°) inthe direction ofthe arrow.Thishelps to
speeduptrack control correctionfor the newtidalvector.
Response
Therearethree responselevels.
Level1isthe defaultand suitablefor mostsituations. Thissetting
provides the best compromise between course-keeping accuracy and
power consumption.
Level2ensures tightercourse-keepingat theexpenseof increased
powerconsumptionand wearandtear duetoincreased pilotactivity.
Itis advisabletouse theminimum responsenecessarytoachievethe
desired course keeping accuracy.
Onlargervessels,level3 canimproveslow speedsteeringwhere
naturalyawdamping of thevessel is reduced.
Note: Level 3 is not recommended for use at planing speeds, or in rough
seas if a rate gyro transducer is not fitted.
