The speed fall by ADR 2 and 1 were enough to disconnect the AP and cause the transition to ALT LAW but why the system is not telling the crew the reason for which it takes these steps ?
NAV IAS DISCREPANCY or SUDDEN CHANGE or UAS ...
This could be a serious help to the crew to understand what's happening and switch to the appropriate procedure.
I have not read the BEA mentioning the
NAV IAS DISCREPANCY ecam msg ... did I miss it ?
Was it available on F-GZCP ?
