avionics suile
in
order to compute the manenvcrs to be performed by the aer-
oplane and actuale them. The below table

In
control
of
the roll axis, the autopilot senses turn rate,
a~
well as closure rate to the sclcclcd
course. along with the non-rate quantities
of
heading error, course error and course dcvialion
indication.
In
conlrol
of
the pilch axis, the autopilot senses vertical speed, acceleration. and closure ralc
lo the selected glidcslope, along with lhc non-rate quantities
of
altitude and glidcslopc devia-
tion indicalion.
The "aulolrim'" function senses when lhe aircrnft needs lo
be
trimmed about the pitch axis,
and responds by driving the trim servo
in
the proper direclion to provide trim.
