It doesn't even get close to full FCS elevator deflection at approach speeds if stopped at 2 ANU,
- are we talking deflection or effect? I have no knowledge of AB THS angles, but what would full deflection at 2ANU achieve? I see mention of THS 13 in AF447 - is that 'sensible'? Presumably CofG and other factors could be used to compute a sensible limit? Remember I am arguing for a 'wake-up call' to the driver, and would full back stick still produce the expected response if the THS had been 'stopped'? There apparently needs to be some way of alerting a crew that auto-trim has gone beyond reasonable bounds and that shirley summat must be wrong?

PS I now have a line in spring-loaded boxing gloves if you want any.
