Thanks for your input. We will improve on the muscle memory with more practice.

thank you,
I m very aware of the bad wind. the issue is familiarity with the engines not on auto. . without
the muscle memory you are likely to over or under shoot. more power i agree is better.
I have no idea how
the auto throttles would work even in a bbj on auto land in that crazy wind.
i appreciate the willingess to
inprove

Hi Jeffrey,
Your suggestion about more stick time in the simulator is well received, and we will try to get that
accomplished next week if the simulator is available.
There are very few times during our simulator training that the Autothrottle is ever disengaged. These few
times are while practicing Steep Turns, Stalls, Emergency Descents, Jet Upset, Engine Failure, Windshear
Escape Maneuvers and during some Missed Approaches. When we hand fly approaches in the simulator
without the Autopilot engaged, the Autothrottle is engaged. It's very rare under normal procedures in the
simulator that the Autothrottle is disengaged.
The Autothrottle is very slow to respond when flying through turbulent air or windshear. On the approach
into St. Thomas yesterday, the wind was variable from 90 degrees (which is 10 degrees to the left of the
runway), all the way to 330 degrees (which is a 40 degree quartering tailwind). As a result of the changing
wind direction, there was windshear and turbulence on the approach. When the Autothrottle could not keep
up, I disengaged the Autopilot and Autothrottle less than two miles from the runway. My initial throttle
input was what I thought was needed at the time. It was in fact more power than was required, but I would
rather have too much power than not enough power.
To prevent such an occurrence from happening again, whenever the wind gust factor exceeds the steady state
wind factor, we will turn the Autothrottle off before the approach begins. Yesterday's wind was reported as
06012G29 (060 degrees at 12 knots gusting to 29 knots).
While flying into Brunswick yesterday the wind was 10 knots gusting to 16 knots. At 3000 feet the
Autothrottle was turned off and the approach was hand flown. Most likely during this approach the
Authothrottle would have performed without incident because there was no turbulence or windshear
encountered.

I apologize for any discomfort that was felt yesterday on the approach into St. Thomas. Of all the times I
have flown into St. Thomas, the wind yesterday was the fastest changing wind direction that I have
experienced there as well as the turbulence and windshear on short final.
Best Regards,
Dave
