Thanks JH for your answer. Yes I agree that I cannot move them when armed. But before, when disarmed, and lever moved then there is a 'speedbrake' indication on ewd. This indication disappears when the spoiler lever is at 0. Now there is no more indication on ewd and no deployment on the aircraft view, so I assume it does not work (confirmed in flight).
By the way, the flaps are working but I realized that there is no change on the aircraft view.
Difficult to fly without spoilers. Any idea to help me ?
