NAT pos'n reprorts. Mag or true winds?
Our FMCs (767 Pegasus) give magnetic winds on the position reoport page but it got me wondering what you use in an oceanic position report since there is such a large variation in...well...variation up near the Canadian coast. Reporting it in the wrong format would screw the plotting charts!
According to the NAT/Oceanic rules, do you report the magnetic or true wind? I couldn't find the answer in any company books or in our copy of the NAT FAA manual.
Thanks.
