The AHRS used in the G500 is limited in its operational area. Operations are prohibited
north of 72 degrees North and south of 70 degrees South latitudes and in the following
four regions:
1. North of 65 degrees North latitude between longitude 75 degrees West and
120 degrees West

114 degrees East

Loss of G500 heading and attitude may occur beyond these regions, but this will not
affect the GPS track.

The Navigation Angle defines whether the GDU 620 headings are referenced to True or
Magnetic North. The Navigation Angle set in the GDU 620 must match that which is set
on the GNS navigator interfaced to the unit.
