Note 2: The EHSI may not display a primary navigational source annunci-
ation if the aircraft is configured to utilize external relay switching instead
of utilizing the KI 825’s internal switching.
1.1.5 SELECTED HEADING
A notched heading bug (amber) is manually rotated around the compass
card by the heading set knob. The heading bug indicates selected head-
ing, and once set, rotates with the compass card. A clockwise (CW)
rotation of the knob produces clockwise (CW) rotation of the heading bug
and vice versa. The knob response will be dependent on the speed of
rotation. A heading control annunciator is displayed next to the knob. A
three-digit numeric heading readout is an indication of the position of the
heading bug and is located on the top left corner of the display just below
the course readout.
1.1.6 COURSE POINTER
When the primary navigational source is a VOR, the selected course
pointer is manually rotated around the compass card by the course set
knob. The pointer indicates the desired navigation course. The color of the
course pointer matches the color of the primary navigational source
annunciation.
When the primary navigational source is a GPS operating in the LEG
mode, the course pointer is replaced with a desired track (DTK) and the
course set knob is not active.
When the primary navigational source is a GPS operating in OBS mode,
the course set knob is used to select the desired OBS course. A clockwise
(CW) rotation of the course set knob produces CW rotation of the course
pointer and vice versa. A course control annunciator is displayed next to
the knob.
1.1.7 COURSE READOUT
The course readout is depicted by a three-digit numeric display located in
the upper left corner of the display and is proceeded by CRS (DTK if
source of data is a GPS that is in LEG mode). The color of this display is
the same as the selected course pointer.
