Wind... True or Magnetic
i have a question about the spot wind on the FMS/GPS
Flying in a area of medium latitude (60°-20°)in a cruise, do you select to have True or Magnetic wind direction displayed by your FMS/GPS?
thanks

BD, true winds are displayed on our FMS, Smiths U10.2, can't help with stand alone GPS units. Sorry. By the way I am talking about the B73NG, I believe Airbus display Magnetic winds ?.

Based on common sense, I'd say that all upper winds displayed by long-range nav systems are true.
In MET reports, winds aloft are always true, whereas the winds given by tower controllers are magnetic.

B757/767 - The EHSI displays magnetic wind velocity if the heading reference switch is selected to "magnetic" and true when "true" is selected.
The FMC "Cruise" page and "Progress" page 2 display true wind velocity at all times, as does the IRS display.
Hope that helps.
