(c) 13) Rotate self-test to OFF Pitch Control Channel Self-Test range. Indicator then increases to right stop
STEP ACTION OBSERVATION
1) With self-test switch in OFF position 2) Rotate self-test switch from OFF to position 1 Meter reads in RED range Meter moves to right at a constant rate for approximately 10 seconds. Rate of movement changes in the YELLOW range

(a) Test wings leveling.
Self-test meter initially deflects to right stop, then decreases and settles in YELLOW range
Self-test meter initially deflects left, then increases, with a decreasing rate in the YELLOW range, to the right stop Self-test meter initially reads zero for approximately 10 seconds, increases, then peaks in the GREEN range for approximately 5 seconds, then slowly decreases left for 110 to 170 seconds Self-test meter settles in the YELLOW range Meter reads in RED range
1) Ground roll TP-11, roll TP-13, roll TP-16, and roll TP-18, and center control wheel. Tilt the vertical gyro for 6.5 degrees of right roll.

2) Engage the AIL engage switch. Observe the control wheel remains centered.
3) Disengage the AIL engage switch, tilt the vertical gyro for 3.5 degrees of right roll, and engage the AIL engage switch. Observe the control wheel rotates counterclockwise.
4) Disengage the AIL engage switch.
5) Repeat 2) thru 4) for left roll and clockwise wheel rotation.
6) Remove grounds and level the vertical gyro.
(b) Test aileron gain. 1) With control wheel centered, engage AIL engage switch and ground roll TP-11, roll TP-13, and roll TP-18.
2) With control wheel centered, tilt No. 1 vertical gyro approximately 2 degrees to simulate a right roll until control wheel is rotated counterclockwise 15 degrees. Observe that required gyro tilt is not less than 1.3 degrees and not more than 2.9 degrees.
3) Relevel vertical gyro, disengage AIL engage switch, and remove ground from
roll TP-11. 4) Repeat 1) thru 3) with No. 1 vertical gyro tilted to simulate a left roll. 5) Disengage AIL engage switch, remove grounds and level vertical gyro.
(c) Test Heading Hold (compass heading displacement) 1) Ground roll TP-13, engage AIL engage switch and ground roll TP-11. 2) Increase compass heading by 10 degrees. Observe that control wheel rotates
counterclockwise.
3) Ground roll TP-14.

4) Adjust No. 1 vertical gyro to center wheel. Ensure that vertical gyro bank angle is not less than 7.5 degrees and not more than 12.5 degrees.
5) Disengage AIL engage switch, remove grounds, level vertical gyro, and reset heading.
6) Repeat 1) through 5) for 10-degree- decrease in heading.
(d) Test CWS Gain 1) Remove hydraulic pressure from control surfaces. 2) Apply 7.5 pound-feet of torque in a clockwise direction to the captain's control wheel. Observe voltage at TP-18 of the roll channel is no less than 4.00 and no
