[CA] [CA11] EV-150 Auto Pilot Issue

[Chuck - Raymarine - Moderator]

greenbunch,

The autopilot speed source (used for all autopilot handling/performance calculations) which I have referenced is different than the Data Sources which is used to select which Speed (STW - Speed Through Water) source will be used by rest of the Raymarine system to report/use STW data. The latter only applies to systems featuring more than one set of sensors featuring speed through water paddle wheels. When operating with the latest available autopilot software, the command sequence previously supplied may be used to select the autopilot's speed source (essentially choosing between GPS based speed data, Speed through water (STW) data, or a designated cruise speed. You may want to check that the Calibration Lock (MENU->SET-UP->AUTOPILOT CALIBRATION->VESSEL SETTINGS->CALIBRATION LOCK) has been configured to OFF.
