c. Attitude Director Indicator (ADI) flags and Horizontal Situation
Indicator (HSI) flags — Check that flags have disappeared. This
indicates that vertical and directional gyros have been ener-
gized long enough to time-out erection cycles (approx. 90 sec-
onds).
d.
ENG Button — Depress. The ROLL, PITCH and LVL lights
will illuminate. The autopilot will oppose movement of the
flight controls.
e.
TEST Button — Depress and hold.
f.

If such disengagement does not occur, it may be disre-
garded since roll axis disengagement is not required.
k.
ENG Button — Depress.
l.
Control Wheel Master Switch — Depress. Check that autopilot
pitch and roll axis disengage.
23. Yaw Dampers — Check as follows:
a.
Primary Yaw Damper PWR/TEST Button — Depress and

Release PWR/TEST button. PWR/TEST light will remain illu-
minated and PRI ENG light will go out.
b.
Secondary Yaw Damper PWR/TST Button — Depress and
hold. PWR/TEST light and SEC ENG light will illuminate.
Release PWR/TEST button. PWR/TEST light will remain illu-
minated and SEC ENG light will go out.

Yaw Force Indicator — Center by rotating control wheel.
d.
SEC ENG Button — Depress.
e.
