...but it will "wake up" on a dark night, scud-running min wx approach at 600 ft if the PF's scan rate fails and he allows the speed to approach the stall
...and it will provide G/A thrust upon TOGA for a go-around (which of course the PF will back up anyway and not forget!)
...and it wont have any effect on an approach unless, once again, the PF's scan rate fails and he allows the speed to approach the stall
Looks like a lot of good stuff for redundancy/safety.
Cheers.
