What happens to thrust in the reported scenario? Landing is usually a combination of pitch and thrust.
If in auto thrust, does the RA trigger a thrust reduction for the flare? If so, and if this was early due to a malfunction or failure, then the crew if unaware of the situation could end up slower than they might expect resulting in a slow/nose high landing?
What triggers the ‘Retard’ call? If this involves the RA, then would a malfunction lead the crew, by habit, to move the thrust levers to idle earlier than normal, again encouraging to a slow/nose high arrival?
