Who do you think Dave, the topic starter, works for??!!
Recently in an approach in a light 319 in moderate to severe turbulence, at night, we could not read the PFDs properly due to eyeball shake. The AP did a superb job but the ATHR did not, sadly.
We were forced to disconnect it to set a mean thrust as the ATHR had got itself totally out of synch with the gust patterns (about 70kts mean @ 2500' with 39kts on the ground).
ATHR was then re-engaged lower down the approach and as we reached the flare, a super-strength gust caused a sudden increase in IAS of about 15kts. A go-around was considered as the ATHR responded slowly.
These kinds of winds are rare, but any company planning to restrict the use of manual thrust will encounter an erosion of skill in its pilots.
