The stall barrier system is constantly monitored for faults or failures.
If a fault or failure in the control column pusher is detected,
messages are prompted for display on CAS.
(3) Angle of Attack Probe:
Two heated Angle of Attack (AOA) probes provide aircraft AOA
information via the Aeronautical Radio Incorporated (ARINC) 429
databus to the DAUs. The left AOA probe provides information to
DAU #1 and the right AOA probe provides information to DAU #2.
AOA values are displayed on the Primary Flight Display (PFD).
The AOA system is constantly monitored for faults or failures. If a
probe heater failure occurs, or data transmitted by the probes to
their respective DAUs is in gross disagreement, messages are
prompted for display on CAS.
3. Controls and Indications:
(See Figure 3 through Figure 6.)
