Dave #1625, but that reply doesn’t answer my question (#1622) whether an AoA display is removed from EFIS with an AOA DISAGREE alert. Lion does not have the mod.

If the AoA display is not removed, then the crew will face further conflicting indications, stick shake, low speed awareness, and an erroneous EFIS AoA display; the latter being of particularly concern given all of the AoA enthusiasts in this forum - ‘AoA is the answer to stalling’. Except in this instance the indication is inaccurate - nose high, requiring a nose down pitch which could be the most unwanted action for the situation.
Yet another weak design feature (there is no third system to compare), and an aspect which again could limit the effectiveness of the abnormal drill.
