OPERATING PROCEDURES

When power is applied to the KCS 55 System the PWR flag will disappear from view if the power
is normal. If the system is in the slaved gyro mode the compass card will automatically fast slave
at the rate of 180 degrees per minute towards the magnetic heading. The system will remain in
this fast slave mode for 120 seconds after which it will automatically revert to the normal slaving
mode and slave at a constant rate of 3 degrees per minute to keep the system aligned with the
earth's magnetic field. The slaving meter on the KA 51 indicates relative deviation from this align-
ment.
When power is applied to the KCS 55A System the HDG flag will remain in view until the following
conditions are satisfied: The gyro spin motor is at least 50% of normal speed, the fast slave mode
has been executed and normal system power is present. The fast slaving mode is initiated when
power is applied and is switched to the slow slave mode when the slaving error is reduced to zero.
The fast slave rate is 180 degree/minute. The slow slave rate is 3 degree/minute to keep the sys-
tem aligned with the earth's magnetic field. The slaving meter on the KA 51A/51B indicates rela-
tive deviation from this alignment.
Set the navigation receiver to the desired VOR/LOC station and rotate the course select knob to
adjust the selected course pointer to the desired course radial. When a usable navigation signal
is received by the KI 525A the NAV warning flag will disappear from view.
The KI 525A lateral deviation bar represents the selected VOR/LOC course. The relationship of
the deviation bar to the symbolic aircraft presents the relationship of the selected course to the
aircraft.
For an ILS approach, tune the navigation receiver to the desired frequency. For LOC operation
the selected course pointer should be set to the inbound localizer course. The glideslope pointer
will deflect into view after a 2 to 12 second delay if a usable glideslope signal is received. The
glideslope pointer indicates the relative position of the glideslope path with respect to the aircraft.
For LOC operation and ILS front course approach, tune the navigation receiver to the desired fre-
quency, set the pointer to the selected inbound localizer course, and if a usable glideslope signal
is received the glideslope pointer will deflect into view. The glideslope pointer indicates the posi-
tion of the glideslope path with respect to the aircraft. The position of the deviation bar with respect
to the symbolic aircraft indicates the relative position of the selected course. For backcourse op-
eration set the course pointer to the inbound localizer course. The deviation bar position relative
to the symbolic aircraft then represents the position of the backcourse with respect to the aircraft.

FUNCTION
When depressed the system is in the slaved gyro
mode. When the button is in the outer position the
system is in the free gyro mode.
When the system is in the free gyro mode, engage-
ment of this pushbutton will cause the compass card
to rotate clockwise at a constant rate of 360 degrees
per minute.
