The tumble detect version, (KG 102A, P/N 060-0015-02), while in slaved gyro mode will automat-
ically switch the system to fast slave mode when rates exceed approximately 25 degrees per sec-
ond. Once the system display (KI 525/525A) matches earth’s magnetic field +/- 2 degrees, the
system will revert back to slow slave mode.
Stabilized heading information is supplied to the KI 525/525A by the KG 102/102A. When in the
slaved gyro mode this heading signal, which may vary at rates up to 30 degrees/second, is
summed with the normal slaving signal from the KMT 112 to provide the final drive signal for the
heading display.
When the system is in the free gyro mode the heading signal from the KG102/102A is the only
input to the heading display drive. While in the free gyro mode the pilot may command changes
in the displayed heading by means of depressing the clockwise or counterclockwise push buttons
on the KA 51/51A (toggle switches on the KA 51B).
