[CA] [CA11] Heading Flash Offset

[Type1]

Yesterday the Raymarine dealer installed the EV1 sensor core on a trial basis and accompanied us on a sea trial. The behavior of the radar image was identical to the behavior with the H1283 sensor, i.e. an installation offset of 16°S (equal to our magnetic variation) was still required to align the image with the ships head. When the 16°S offset is dialed in the head up image in the radar app becomes properly aligned, but the radar overlay in the chart app then rotates out of alignment by the same amount.

We appreciate Raymarine providing the EV1 sensor on loan. This was a useful exercise in that it has ruled out the heading sensor as the source of the issue. Does this now look like a software issue?

We continue to operate with our heading sensor disconnected until a solution can be found.
