TCAs - groundspeed

Maybe it has groundspeed as input.

I suppose - please correct me if i am wrong - that groundspeed is provided by the Inertial Reference Units only (not ADRs).

All those warnings begin

The crew guesses by turning ADR1 off. Only PRIM2 detects the move.

The ISIS, which is fed by ADR1 input, complains.

this fault is "timestamped" at 2:11 - was received (or transmited) at 2:13

Maybe it was triggered at 2:10 and received by the CMC at 2:11.
