A320:Unreliable Airspeed
In unreliable airspeed the FCTM states:ONE ADR OUTPUT IS ERRONEOUS AND THE TWO REMAINING ARE CORRECT :The ELACs and the FAC and/or FMGC eliminate the erroneous ADR.There is no cockpit effect (no caution, normal operation is continued), except that one display is wrong and the autoland capability is downgraded to CAT 3 SINGLE.
Suppose ADR 1 is erroneous.My PFD will show me the wrong airspeed.Will I not get any indication of the IAS discrepancy ?
