At a convenient stage, before or during taxi, and before arming the autobrake, the PF silently applies full longitudinal and lateral sidestick deflection. On the F/CTL page, the PNF checks and calls out full travel of elevators and ailerons, and correct deflection and retraction of spoilers. As each full travel/neutral position is reached, the PNF calls out:
"Full up, full down, neutral"
"Full left, full right, neutral"
The PF silently checks that the PNF calls are in accordance with the sidestick order. -FCTM
The note referred to by John Smith implies ,imho ,that if a spoiler for example has failed the position of the surface cannot be deduced from the sidestick order symbol, however the direction the stick has been moved, and the order symbol should be in agreement with the surface deflection.
