- Auto pilots require a heading sensor. When they work properly they are properly aligned with magnetic north and they allow you to engage the autopilot to steer the point to a waypoint (destination) or a series of waypoints. Whey they are not calibrated properly, their functionality is less than desirable to possibly ineffective. Following installation last year, we had several months of trial and error in our set up and location of the heading sensor (free from other magnetic influences on our boat). By September it was all sorted out and working well
- Today, as we approached Kingston, it started to misbehave. It took five minutes or so for me to remember that just west of Kingston there is a well known “magnetic anomaly” that will throw off a regular compass, an auto pilot heading sensor and anything else that relies on magnetic north. Over the course of a few miles our heading sensor moved about to an unnerving extent. I have my fingers crossed all will be normal when we depart Kingston harbour.
