    How to display / calculate TWD and TWS?

    Hi,
    How to best display TWD and TWS?
    I am connected to a NMEA 2000 bus and B&G plotter via Actisense box. In expedition, I can view GPS, BSP as well as AWA + AWS. How can I get to display TWD and TWS? Should I let expedition calculate them? What is the best way to do this?

    Thanks a lot!

    Do you have a compass?

    If they aren't available from the instruments, you can tell Exp which vars to calculate in the Exp system settings window.

    OK, thank you!
    It should be available but it does not seem to get to Exp, only AWA, AWS, so I will try to calculate it.
    Which system settings window exactly? I have tried several options but can't find the right one.

    Thanks again.

    The Calculate section on the System settings page.

    Also see the Exp System settings and Instruments Calculations help topics.
