Four pairs of eyes including one TRE didn't pick up the embarrassing reason for RTO and subsequent return to stand on the 380 last week.
Reason for RTO = no FMA indications when take off thrust selected.
Reason for no FMA indications= both Flight Directors off.
W.K. does have a point however not very diplomatic put. As woodja says a double edged sword. Should this incident turn out to be a data entry error however then I am sure we will here much more about the active role of augmenting crew.
