EMERGENCY OPERATION IN CLOUDS

If the vacuum pump fails in flight, the standby attitude indicator will not
be accurate. The pilot must then rely on the attitude and heading
information (from the AHRS) shown on the PFD indicators. With valid
HDG or GPS/NAV inputs, autopilot operation will not be affected.
If a single AHRS unit fails in flight (red X's shown through the PFD
attitude and heading indicators), the pilot must rely on the cross-side
AHRS for attitude and heading information.
The autopilot will not operate if a single AHRS unit fails. The pilot must
manually fly the airplane with cross-side AHRS input. Refer to Section
7, Airplane and Systems Description, for additional details on autopilot
operations.
The following instructions assume a dual AHRS failure and that the
pilot is not very proficient at instrument flying and is flying the airplane
without the autopilot engaged.
