PRIMUSr 1000 Integrated Avionics System
A28--1146--112--00
AHZ--800 Attitude and Heading Reference System (AHRS)
A--6
D MAG/DG (Magnetic/Directional Gyro) Switch -- When the pilot
inputs the MAG value, either a flux valve compensated heading, or
DG only heading is displayed.
NOTES: 1. If MAG is selected while in level flight, the AHRS
instantly returns to flux valve slaving. However, if
MAG is selected while in a turn, slaving starts only
after the bank is reduced to a small value and
occurs at 1_ per minute.
2. While in MAG, no display of flux valve slaving
occurs.
D CW/CCW (Clockwise/Counterclockwise) Switch -- When a DG
heading is displayed, the CW/CCW switches let the pilot enter the
desired heading.
