  • Page 47: Auto Mode

    Other relevant settings are described under STANDBY mode in this chapter. Response The Autotune function in the AP26 and AP27 is so refined that 80-85 % of the boats will need no further adjustments of the steering parameters. On some boats, however, or at particular sea conditions a fine tuning of the steering parameters may improve the performance of the autopilot.

  • Page 118 Glossary True bearing – Bearing relative to true north; compass bearing corrected for compass error. True heading – Heading relative to true north (the meridian). Waypoint - A discrete point, stored in a navigator, located on the surface of the earth. Normally this point will be identified by Lat/Lon coordinates although in some systems it may be shown by T.D.'s.
