There are two Angle sensors on each Thrust Lever. If the two sensors disagree about the TLA, on the ground, but not at TOGA or FLX/MCT (i.e. take-off thrust setting), the FADEC selects Idle thrust irrespective of thrust lever position. An ECAM warning occurs and as part of the drill the pilot backs this up by selecting idle.
Question: if we have TLA sensor disagree, does this count as TL idle regarding the spoiler extension logic? in other words, would the ground spoilers extend with TL 1 rev, TL 2 TLA sensor disagree and the lower half of the diagram in TRUE mode (wheel speed or both MLG compressed)?
