Navigation angles (track, heading, course, bearing) are set on the AUX – SYSTEM SETUP Page and are either
corrected to the computed magnetic variation (MAG VAR) or referenced to true north (denoted ‘T’). When an
approach referenced to true north has been loaded into the flight plan, the system generates a message to change
the NAV ANGLE setting to TRUE at the appropriate time.
