I have two points that may need clarification.
1. How big should the difference from the median AoA be in order to reject ADR1?
2. Could this be the cause of a) autopilot disconnect, (b) false interpretation as due to pitot problem if ADR1 was permanently rejected due to AoA error.
1/ Don't know, actual values are not given in the documentation.
2/ a) No, all AoAs are within 1 degree of one other @02:10:05
2/ b) No, an AoA error wouldn't reject all ADR signals, its the CAS <60Kts which will invalidate the AoA signal (0 degree and SSM to NCD).
Regards.
