15.7.2 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. When configured by the installer,
there may also be a fourth option: External. If “External” is selected, the GTN
Nav Angle will be synchronized with the on-side MFD.
NOTE
: When changing the Nav angle, the DTK on the Flight Plan page
for an approach does not change until that approach is reloaded.
