Maybe not, provided that in the CRZ
pitch and power along with
static pressure and altitude is automatically monitored independently and if UAS starts to become an issue for the A/P it switches to flying the "pitch and power" equivalent to the last valid pitot data. Signal the UAS condition and at the same time show the FPV value. The crew are now aware of the condition, and the "suprise" factor has been mitigated.
As an after-thought,
GPS Altitude and GS could be incorporated into the monitored triangle as a backup, should one of the other two components become suspect.
I know its not the total answer, but who/what judges the Judges?
