[TG] [TG11] p70s & i70s - wind

[Tom - Raymarine - Moderator]

Hello Watsala,

This isn't a calibration, setup or software problem, it's that the i70 and p70 aren't displaying exactly the same types of data.

The compass-rose type display of the p70's Graphic page layout always shows True wind direction, since it's related to north in that graphic rather than the vessel's bow. Changing the p70's 'Wind Vane Type' changes how the pilot steers in windvane mode but not the displayed wind data on the Graphic page.

In your image Wind2 you have 4 knots of apparent wind dead on the bow but 6 knots of boatspeed, implying a 2 knot air from astern, which is why you can't see the wind indicator on the pilot display.

In your image Wind1 you have 8 knots of AWS just to port of dead ahead and 5.5 knots of boatspeed implying a true wind on the port bow, which is what the pilot shows. Since you're in Vane mode you can also see the current locked wind angle that the pilot is trying to steer to, 31 degrees Port, which would have been the wind angle (apparent or true, whichever was configured in 'Wind Vane Type' at the time when you entered Vane mode.

If you want to display AWA and AWS on the p70, change to 'Multi' view mode and configure the appropriate data-boxes. You will find that these agree with the i70.

To answer your second question, calibration is always stored in the piece of electronics where the transducer is directly connected: in this case, the ITC5.

Regards,
Tom
