16.6.2 Setting a User-Configured (Manual) Nav Angle
There are three variation (heading) options: Magnetic, True, and User. If
“Magnetic” is selected, all track, course and heading information is corrected
to the magnetic variation computed by the GPS receiver. The “True” setting
references all information to true north. The “User” selection allows the pilot to
enter values between 0º and 179º E or W.
NOTE: When changing the Nav angle, the DTK on the Flight Plan page
for an approach does not change until that approach is reloaded.
1. While viewing the System page, touch Units key.
