3.1.1 KI 525/525A INDICATOR AND CONTROLS
INDICATOR AND CONTROLS FUNCTION
Compass Card:
This rotating card displays gyro stabilized magnetic
compass in formation beneath the lubber line.
Heading Select Knob:
Positions the heading select marker relative to the
compass card.
Symbolic Aircraft:
Represents the relationship of the aircraft with respect
to the display.
Reciprocal Course Pointer: Indicates the reciprocal of the selected course.
Course Select Knob:
Positions the selected course pointer with respect to
the compass card.
Lateral Deviation Bar:
Represents VOR radial or LOC course. When refer-
enced to the symbolic aircraft the position of the devi-
ation bar is the same as the position of the chosen
VOR radial or LOC Course to the air craft.
Glideslope Pointer:
Represents the actual aircraft deviation from the
glideslope path. When unusable glideslope informa-
tion is present the glideslope pointer is biased out of
view. When a valid glideslope signal is received there
is a 2 to 12 second delay before the pointers come
into view.
Heading Select: Indicates the selected aircraft heading.
NAV Warning Flag:
When unusable VOR/LOC information is present the
warning flag is in view.
Lubber Line: Aircraft magnetic heading is read under this line.
Heading Warning Flag: (KI 525A only)
Inadequate Power, manual slave, fast auto slave or
spin motor less than 50% normal speed.
Power Flag (KI 525 only) Inadequate Power.
Selected Course Pointer: Indicates the selected VOR radial or LOC course.
To-From Indicator:
Indicates the direction to the VOR station along the
selected radial.
Slaving Meter:
Indicates the difference between the displayed head-
ing. Positive deflection indicates a clockwise error of
the compass card.
Counterclockwise Manual
Heading Drive Pushbutton:
When the system is in the free gyro mode, engage-
ment of this pushbutton will cause the compass card
rotate counterclockwise at a constant rate of 360 de-
grees per minute.
