Version 15.0 AF-5000 Series Pilot Guide 33
Dual AHRS Monitoring
If a system has two ADAHRS units the EFIS screen will constantly compare both ADAHRS units for a
mismatch error in Roll, Pitch, or Heading an AHRS MISMATCH error will be displayed on the center of
the screen. You can select the ADAHRS that the system is using from the OPTIONS MENU (Touch the
center of the PFD display). Selecting an ADAHRS on the Pilot PFD EFIS screen will force all MFD
displays to use the same ADAHRS. Selecting an ADAHRS on a MFD display will only change it on the
MFD and only for that EFIS power cycle.
