Hey ZONNAIR Just tried looking in the FCOM regarding spoilers activation, in an auto land, in case one does not bring the thrust levers back from CL gate to idle and FMA shows idle, after touch down ground spoilers would not activate???
As the book says "IF THE GROUND SPOILERS ARE ARMED AND THRUST LEVERS ARE AT IDLE GROUND SPOILERS WILL ACTIVATE AS SOON AS LANDING GEAR TOUCH"
