INTRODUCTION
This section contains supplemental information to operate, in a safe and efficient
manner, the aircraft when equipped with S-TEC Fifty Five X autopilot device
interfacing Garmin G950 IFDS.
GENERAL
The System Fifty Five X is a rate based autopilot. When in control of the roll
axis, the autopilot senses turn rate, as well as closure rate to the selected course,
along with the non-rate quantities of heading error, course error and course
deviation indication.
When in control of the pitch axis, the autopilot senses vertical speed, acceleration,
and closure rate to the selected glideslope, along with the non-rate quantities of
altitude and glideslope deviation indication.
These sensed data provide feedback to the autopilot, which processes them in
order to control the aircraft through the use of mechanisms coupled to the control
system.
The “autotrim” function senses when the aircraft needs to be trimmed about the
pitch axis, and responds by driving the trim servo in the proper direction to
provide trim.
