Instrument Remote Controllers
Figure 4--3
The function of each control on the pilot’s and copilot’s controller is
described in the following paragraphs.
D HDG (Heading) Select Knob and PUSH SYNC Button -- T h e
HDG knob is used to set a heading reference by positioning
the heading bug on the pilot’s or copilot’s EHSI.
Pushing the PUSH SYNC button synchronizes the heading bug to
the present heading (lubber line).
D CRS (Course) Select Knob and PUSH DCT (Direct) Button --
The CRS knob is used to set VOR or ILS course by positioning the
course select pointer on the pilot’s or copilot’s EHSI.
Pushing the PUSH DCT button automatically slews the course
pointer to center the course deviation to the tuned station.
When FMS is selected, the pilot can preview an on--side localizer
course. When in the course preview mode, turning the CRS knob
replaces the desired track (DTK) annunciator with CRS and sets the
localizer course. The digital preselected course readout is removed
5 seconds after the CRS select knob is turned.
