Beechcraft 1900D

[itsresidualmate]

Gents, need help from Beechcraft 1900D pilots on a couple of questions!

1. On the autopilot control panel there's a button marked 'SR'; what is it?
2. The status/fault codes that appear in the A/P panel window, do you know what they relate to? I assume that;
YAW DIS - yaw damp disconnect
AP DIS - A/P disconnect
T - ?
AP - ?
A - Aileron
R - Rudder
E - Elevator
1/2 - ?
SR - ?
Trim Trim - Not sure exactly, probably the electric pitch trim?

Any help much apprieciated!!

I used to operate a B200.

SR refers to 'slow roll, (or soft roll I think). I believe if makes the AP behave with a slow rate in turns for pax comfort.

1/2 refers to half bank.. 17.5 degrees but don't quote me, again for pax comfort but might be a consideration to use this during single engine ops and AP engaged.

It was 4 years since I last flew one of these so don't quote me!

Hi!
The information I have comes from the 350 manual, but it should be the same.
SR means Soft Ride and reduce the response of the Autopilot during turbolent flight.
Which model of autopilot there is on the 1900? Autopilot is an optional and maybe is different...
The two trim annuciators are in different colors? Maybe one is for the "trim in motion" an the other te 2trim failure2
AP should be Autopilot failure annuncietor, but you have more annuncitors than me so probably is a different model.
Just my two cent
